JUNE 21, 2016 — Rolls-Royce is investing EUR 57 million (about $64 million) to upgrade its azimuth thruster production facility in Rauma, Finland, consolidating assembly and test capability and modernizing the operation
Over the years, the use of azimuth thruster has changed the way operators do business. The increased maneuverability and efficiency gains allow tug operators to do more with the same installed power. Added maneuverability can also play a role in improving safety during certain operations. With more than 50 years of developing and manufacturing azimuth thrusters, Rolls-Royce has learned a lot about the specific propulsion requirements of different types of ships and floating structures. Working close with the customers has been a key element of the success.
Steerable azimuth thrusters have come a long way since the first one went into service in 1965. With just 80 hp of thrust it was installed on a mud hopper barge in Finland to make it self-propelled. The first azimuth units specifically designed for inland waterway applications were delivered in 1976. They powered a series of three-river push boats built in Holland and are still operating today.
With the aid of modern computer-based design tools and a detailed understanding of hydrodynamics, Rolls-Royce is continuously developing and improving its thruster product range. The current product portfolio covers a power range of 300 to 14,000 hp.
The benefits of Azimuth thrusters on a towboat
With an azimuth thruster the full thrust can be applied in any direction through the full 360 degrees and significantly improve the maneuverability and braking force of the vessel. In performance tests it has been shown that the braking forces produced are nearly 1.5 times those of the conventional towboat, over the whole speed range. This increase in braking force reduces both the distance and the time needed to stop a barge train.
For shallow draft operations, the normal requirement is to fit 2 azimuth units, and it is not unusual to have towboat designs with a triple azimuth thruster propulsion arrangement.
Azimuth thrusters also significantly increase flanking forces, which help operators safely navigate through the most difficult bends of the river. On a conventional towboat, flanking rudders and reverse thrust are normally used to produce the necessary flanking forces. By using azimuth thrusters the transverse force can be maximized and is approximately twice the maximum side force produced by a conventional towboat at all measured speeds, plus there is the benefit of greater braking forces. Maximum flanking forces produced can be up to 4 times that of the conventional towboat with equal braking force.
How Azimuth thruster help in Brazil
Brazil is a country traversed by many rivers, the main one being the Amazon. There are 11 main inland waterways with a total length of some 39,000 miles although only approximately 8,000 miles are regularly used. These waterways are used to transport agricultural commodities such as grain and fertilizer, as well as mineral goods to the coast.
Amaggi Navegação a subsidiary of Amaggi Exportação e Importação Ltda. is one of the operators working in the region who has moved to azimuth thrusters to propel their vessels. They have been operating on these waterways for over 20 years and now have over 30 tugs equipped with azimuth thruster propulsion. Units in their fleet include a range of Rolls-Royce thrusters from our smaller US 105 model to our larger US 255’s.
Amaggi Navegacao operate on the Madeira and Amazones rivers where they are involved in the transportation of grain and soya to and from local processing plants. The move away from conventional towboat design has enabled them to increase the size of barge trains, which is due to increased turning and stopping capacity at full load.
Open prope
llers are used for the majority of these thruster applications due to the amount of debris in the rivers. The trend outside the Amazon is to fit azimuth thrusters with nozzles and thereby maximize thrust.
The future of Azimuth thrusters
Thruster technology continues to develop. The latest is the introduction of gearless electric drive through the application of permanent magnet (PM) rim drive technology, where the motor surrounds the propeller as a slim ring. The rotor is integral with the propeller and carries a series of permanent magnets. As the magnetic fields interact, the propeller turns. Tunnel thrusters and azimuth thrusters utilizing this technology are now available from Rolls-Royce. The compact and efficient tunnel thruster unit is easy to install and power output is increased by around 25% for the same propeller size. It is a good example of the possibilities that lie ahead.
This technology has now been applied to the azimuth thruster by Rolls-Royce, and the first PM development thrusters rated at 670 hp were installed on the research vessel R/V Gunnerus in March 2015. Nozzle shape can be selected to suit individual applications, but since Gunnerus requires pull for towing trawl and other gear, the nozzle is optimized for bollard pull and speed to match the vessel’s requirements. The installation is compact with only the slip ring unit and the variable frequency steering motors inside the hull.
Before the installation, the vessel had a conventional diesel electric propulsion system consisting of frequency converters, induction motors, gears and shaft with nozzle propeller. Testing to date has demonstrated an improvement in propulsive efficiency and bollard pull with a reduction of air and structure borne noise and vibration.
MAY 26, 2016 — Rolls-Royce has signed a contract with Spanish shipyard Astilleros Gondan to supply the design and equipment for the second UT 540 WP design Service Operation Vessel (SOV) that
Soon, noon-day reporting from fallible human beings will be a thing of the past. From cradle to grave, a whole new approach to ship efficiency has been made possible by recent advances in IT and data processing. Now, a step change in “always-on” ship connectivity will allow maritime assets to be monitored and managed remotely right round the clock.
As we reported in “Shipping’s Space Age Future” (ML April 2016, p. 37), perhaps the most ambitious project on the go in Europe is the Rolls-Royce-led Advanced Autonomous Waterborne Applications Initiative (AAWAI) in which other maritime firms including DNV GL, Inmarsat, Deltamarin and NAPA are also involved. Other participants include top academics from various Finnish universities.
At a project update meeting recently in Helsinki, Rolls-Royce President – Marine, Mikael Makinen declared: “Autonomous shipping is the future of the maritime industry. As disruptive as the smart phone, the smart ship will revolutionize the landscape of ship design and operations.”
Delegates heard that the sensor technology is now sufficiently sound and commercially available so that algorithms required for robust decision-making—the vessel’s virtual captain—are not far away. Now the arrays of sensors are to be tested over the coming months on board Finferries’ 65-meter-long double-ended ferry, Stella.
“Some of the distinct goals of this project are to make a difference in marine safety and energy efficiency,” Päivi Haikkola, Manager, R&D, Deltamarin Ltd., told Marine Log. “We want to mitigate human error.”
Finferries and dry bulk shipping company ESL Shipping Oy are the first ship operators to join the project, which aims to explore ways in which to combine existing communication technologies as effectively as possible for autonomous ship control. Inmarsat’s involvement is key.
The London-listed communications company recently began the roll-out of its new Fleet Xpress service, seen by many as truly a light-bulb moment. Preparing the ground for rapid advances in smart ship operation and crew welfare, the new service now provides always-on high-speed broadband communication between maritime and offshore assets at sea, and shore-based managers. It is the first time that such a service has been available from a single operator.
Fleet Xpress will also facilitate cloud-based applications from third parties with smart systems to raise ship operating efficiency and improve the life-quality of seafarers. For the first time, big data can be used to improve asset management and maintenance.
IT advances have also facilitated a new approach to ship design. Model basins and testing tanks still have their place, of course, but thousands of relatively high-speed computational iterations can measure the relative benefits of small design changes in a way that has not been possible before.
Take the Finnish company Foreship, for example. Its capabilities in computational fluid dynamics (CFD) and the super-efficient hull forms which it has developed have propelled the company into a position as one of the top ship design consultants to global cruise lines, advising both on newbuilding plans, conversions and retrofits.
In a couple of months, the first of two 4,700 dwt “EcoCoaster” cargo ships is due for delivery to Finland’s Meriaura Group from the Royal Bodewes yard in the Netherlands. Foreship carried out extensive hull optimization work and, as a result, these vessels will burn only about half of the fuel compared to an existing vessel of similar size and class.
Foreship worked with both the owner and Aker Arctic Technology on the ships which will be able to run on biofuel or marine gasoil. Meriaura plans to have at least half of its fleet – currently about 20 ships – based on EcoCoaster designs by 2020. Since ordering the 4,700 dwt units, work has been carried out on larger designs.
Also hailing from Finland is progressive ship design firm Deltamarin. Now a subsidiary of Singapore-listed AVIC International Maritime Holdings Limited and ultimate Chinese ownership, the company’s range of super-efficient B.delta bulk carriers spanning a size range from 28,000 dwt to 210,000 dwt has caught the attention of long-established dry bulk owners including heavyweights such as Algoma, Canada Steamship, Cosco, Louis Dreyfus Armateurs and Oldendorff.
Of course the catalyst for taking a fresh look at the hull forms which had not changed for decades was the spike in bunker prices. But although the oil price collapse means today’s fuels cost only a fraction of prices two or three years ago, the search for improved economy has developed a momentum of its own, and nowhere is this more obvious than amongst leading propulsion companies, many of which are to be found in Europe.
While big low-speed diesel manufacturers like MAN Diesel & Turbo and Wärtsilä have made huge strides in raising the fuel efficiency of large engines, it is among some of the smaller niche machinery providers where true design innovation is to be found. Electrical power, energy storage and the growing popularity of azimuth thrusters are fiercely fought-after markets. ABB, Rolls-Royce, Steerprop, and Wärtsilä all feature in a market popular with operators of cruise ships, workboats, offshore support vessels and dynamically positioned offshore units of various types.
ABB, for example, recently won a European Marine Engineering Award for its Azipod D electric propulsion system with a power range from 1.6MW to 7MW. Launched last year, the latest Azipod was designed to allow its use on a wider range of ship types. It incorporates various innovative features including a new hybrid cooling system which contributes to a requirement for 25% less installed power and similar fuel savings.
The first cruise ship with Azipod D will be the 16,800 gt Scenic Eclipse being built by Uljanik shipyard in Croatia. The Scenic Eclipse (pictured above) is being built to Polar Class 6 and will operate in the summer waters of the Polar regions when it is delivered in 2018. The 228-passenger ship will have two 3MW Azipods installed.
Meanwhile, ABB recently announced a deal to supply a new electrical power system based on its Onboard DC Grid system for a hybrid car ferry in Norway. Initially the vessel, for Torghatten Trafikkselskap will operate as a hybrid with two battery packs contributing to peak demand. However, the 60-car, 250-passenger vessel can be easily modified to become fully electric in due course by adding 16 battery packs and a shore connection.
For the cruise ship and offshore vessel markets, Wärtsilä recently unveiled the Wärtsilä WTT-40 transverse thruster, which features a 4,000 kW power level and a 3,400 mm diameter controllable pitch propeller. The thruster complies with the U.S. EPA’s latest VGP2013 regulations. It also features integrated hydraulics to save machinery room space and installation and commissioning time in the shipyard.
Meanwhile, last year Steerprop Ltd. landed orders for a total of ten SP25D units to serve as main propulsion for three inland towboats being built for SCF Marine at C&C Marine & Repair, Belle Chasse, LA. The propulsors will be delivered this summer to the shipyard by Karl Senner, LLC., Kenner, LA, the North American distributor for Steerprop. These will be the largest and highest horsepower inland towboats equipped with Z-drives built in North America to date, according to Chris Senner of Karl Senner, LLC. He adds, “It is imperative to consider the harsh conditions of the inland waterways and select a unit suited for the environment, which is why we propose the equivalent of an ice-class rated unit.”
A new generation of much more fuel and operationally efficient newbuilds, however, does nothing for the tens of thousands of existing vessels built before the new wave of design innovation began. But there are a range of initiatives in progress focused on enhancing existing ship efficiency.
Germany’s Becker Marine Systems is a leading light in energy-efficient retrofits and appendages. The company recently signed a deal with Abu Dhabi’s Adnatco to fit some 20 vessels with Becker Mewis Ducts (pictured at right). Rudder modifications and Becker Twisted Fins are also generating a steady pipeline of sales.
Walter Bauer, Sales Director, concedes that sales volume has reduced. But he says that this is partly a result of the dire state of the bulk carrier market. Tanker business, he says, is holding up well.
But what to do with almost-obsolete panamax container ships? Owing to beam constraints, they are generally long and relatively thin, and were mostly built in an era of cheap fuel and fast sailing speeds. They are not particularly efficient from a box-carrying point of view, but are in dire straits today, competing with larger ships and lower slot costs. There are more than 800 such vessels in the world fleet today and well over half are less than 10 years old. They are likely to prove increasingly unpopular with charterers.
Cargo access specialist MacGregor is one of several companies which offers capacity increasing conversions for container ships. By slicing a vessel in half lengthways, a newly constructed midship section can be inserted and stack heights raised by lifting the navigation bridge.
In a similar project, the capacity of the 4,860 TEU MSC Geneva, owned by Reederei NSB, was increased to 6,300 TEU. The five-month widening project, undertaken in close cooperation with Hamburg’s Technology GmbH, was completed at Huaran Dadong Dockyard in China. Through its subsidiary NSB Marine Solutions, Reederei NSB is now offering to assist in similar projects for third parties.
MAY 9, 2016 — The new polar research vessel under construction for the U.K.’s Natural Environment Research Council (NERC) at the Cammell Laird shipyard on Merseyside is being built to a Rolls-Royce
Looking like a teaser for an upcoming Star Trek movie, a six-minute video posted by Rolls-Royce last month lays out its high-tech vision of unmanned cargo ships and the future of shipping.
At the heart of that vision is a sophisticated, cutting-edge, land-based control center with interactive smart screens, voice recognition systems, and 3D holographic images of the ship and its equipment. An officer sits in a command chair before the “OX global wall,” which provides a worldwide overview of shipping traffic. Flying drones launched from the unmanned ship are the operator’s eyes in the sky to monitor navigation, security, weather and inspect the ship itself.
In the video, Rolls-Royce envisions a small crew of 7 to 14 people that will monitor and control the operation of a fleet of vessels across the world.
Last year, Rolls-Royce announced it would lead the Advanced Autonomous Waterborne Applications Initiative—a new EURO6.6 million project to explore, develop and design autonomous ships.
Tekes, the Finnish Funding Agency for Technology and Innovation, is providing the funding for the project, which will run until the end of 2017.
The Advanced Autonomous Waterborne Applications Initiative (AAWAI) brings together expertise from academia and industry. The participants include Finnish academic researchers from Tampere University of Technology, VTT Technical Research Centre of Finland Ltd, Åbo Akademi University, Aalto University, and the University of Turku. Besides Rolls-Royce, industry participants include NAPA, Deltamarin, DNV GL and Inmarsat.
Iiro Lindborg, Rolls-Royce’s General Manager, Remote & Autonomous Operations, Ship Intelligence, says, “unmanned and remote-controlled transportation systems will become a common feature of human life. They offer unprecedented flexibility and operational efficiency.” Lindborg says the research “aims to understand the human factors involved in monitoring and operating ships remotely. It identifies ways crews ashore can use tools to get a realistic feel for what is happening at sea.”
The video is the final stage of research that will inform the design and construction of a project demonstrator before the end of this decade.
An effective remote operations center is essential to the company’s plans to develop autonomous and remote controlled vessels.
Eija Kaasinen, Principal Scientist at VTT Technical Research Center of Finland Ltd., points out that unmanned ships doesn’t take humans out of the picture totally. “Unmanned ships need to be monitored and controlled and this will require entirely new kinds of work roles, tasks, tools and environments. The future shore control center concept has been designed by emphasizing the user experience of the human operators. By focusing on the operators’ point of view, it is possible to introduce meaningful, pleasurable and engaging new roles for the ships’ shore control center professionals.”
The research was undertaken by VTT and University of Tampere research centre TAUCHI (Tampere Unit for Computer Human Interaction) in collaboration with Rolls-Royce. It explored the lessons learned from other industries where remote operation is commonplace, such as aviation, energy, defense, and space exploration.
It uses the InnoLeap approach, a VTT and Rolls-Royce-developed initiative for concept design and presentation of academic studies in a graphic format that is based on trend and user studies, co-innovation, scenario stories and visualizations.
On April 5, in Helsinki, Finland, Rolls-Royce will reveal separate research findings, which it believes will set the direction for the development of remote and autonomous shipping.
Remote and autonomous ships are one of three elements of the company’s Ship Intelligence strategy, a portfolio of products and services – comprising health management solutions, optimization and decision support, and remote and autonomous operations – which intended to enable customers to transform their operations by harnessing the power of big data.
Rauli Hulkkonen, Tekes, Chief Advisor, thinks the project is a “fantastic opportunity to establish the Finnish maritime cluster as the world leader in maritime remote control technology.”
Esa Jokioinen, Head of Rolls-Royce’s Blue Ocean Team, says, “We are excited to be taking the first concrete steps towards making remote controlled and autonomous ship applications a reality.”
The Rolls-Royce Blue Ocean team is responsible for R&D of future maritime technologies.
Rolls-Royce is not alone in investigating the feasibility of unmanned ships. The European Commission has just completed work on project MUNIN (Maritime Unmanned Navigation through Intelligence in Networks) to develop concepts for unmanned ships. The EURO3.8 million MUNIN project focused on a dry bulk carrier concept, which typically carry cargo point-to-point on long, uninterrupted deep-sea voyages.
The goal of the projects is to reduce crew costs, lower environmental impact, and reduce the number of collisions. Human error plays a role in about 80 percent of maritime accidents.
MUNIN says that the issues of cyber attacks and pirates are a cause for concern. “However, software systems as well as ships can be designed and built providing a very high resilience against digital and physical attacks.”
HUNTING SUBS BY DRONE SHIP
Drones have been used effectively on the military side for years for surveillance, reconnaissance, and military strikes. Last month, the Defense Advanced Research Project Agency (DARPA) reported that its Anti-Submarine Warfare (ASW) Continuous Trail Unmanned Vessel (ACTUV) program has designed, developed and constructed an entirely new class of ocean-going vessel—one intended to traverse thousands of kilometers over the open seas for months at a time, all without a single crew member aboard.
The ACTUV technology demonstration vessel was recently transferred to water at shipbuilder Vigor Industrial, Portland, OR, and conducted speed tests in which it reached a top speed of 27 knots (31 mph/50 kph).
The ACTUV would be used to track quiet diesel-electric submarines.
The vessel is scheduled to be christened on April 7, 2016, with open-water testing planned to begin in summer 2016 off the California coast.
OPEC’s December decision to maintain oil output may not be doing any favors for U.S. shale producers, but continuing investment by national oil companies around the Arabian Gulf is underpinning a wide range of offshore-related projects and creating opportunities for regional shipyards.
There has, of course, been a sharp downturn in charter rates—the world’s largest energy firm Saudi Aramco, for example, told suppliers including Offshore Support Vessel (OSV) operators earlier in the year that it expected cuts in rates of 20-30%. Many regional OSV owners are under serious pressure.
But while shipyard prices are also sharply constrained, there is no shortage of work. Oil producing countries are geared to pumping as much oil as possible and making the most of the opportunity to grow their market share. Both Saudi Aramco and the Abu Dhabi National Oil Company (ADNOC) have revealed that they have no plans to cut back on exploration and production although, to be fair, the Saudi energy company has stopped exploring in the Red Sea for the moment.
Both oil companies have huge capex programs, however. ADNOC has plans to raise oil output by a quarter, to 3.5 million b/d by 2018. The company plans to spend close to $100 billion over the next four years, it revealed last May. More than $60 billion will be spend over the next two years. A significant proportion of the money will be channelled offshore in vast oil fields that lie in shallow water. The oil-rich Emirate is developing some of its offshore reserves by creating artificial islands that provide a cheaper means of production for long-life fields than chartering jack-ups.
With relatively low production costs, Middle East oil producers are less vulnerable to low prices than almost everyone else. The continuing drive to explore and develop more reserves has been a major catalyst in the drive by regional shipyards to target the offshore sector. Heavyweight repair yards including ASRY in Bahrain, Drydocks World Dubai and N-KOM in Qatar have all developed substantial revenue streams from the offshore sector in recent years.
Now, several new yards are targeting the offshore market. The family-owned Zamil Group officially commissioned a new shipyard built on reclaimed land last April. The 2.5 million ft2 facility has been designed not only to build and repair the group’s own vessels—it has a fleet of 76 vessels, mostly OSVs—but also to work on other ship- and offshore-building projects for third parties.
A few miles down the coast, Dammam Ship Repair Yard is also gearing up to take on more business in the offshore sector. The yard has already undergone a significant upgrading under ownership of the Al Blagha group, with two floating docks of 22,000 tonnes and 10,000 tonnes lifting capacity refurbished and brought back into class. Buildings, workshops and yard infrastructure has also been overhauled and upgraded.
Now though, yard management is targeting international offshore operators working in Saudi waters. Mobile repair teams from the shipyard have been deployed on rigs offshore, carrying out a range of projects. Meanwhile contractors including Ensco, Rowan, Noble and Seadrill all carried out jack-up rig repairs, upgrades and modifications during 2015.
Elsewhere in the Gulf, Damen Shipyards Sharjah is also eyeing the offshore sector. The new facility, which is a joint venture between the global shipyard group and locally owned Albwardy Marine Engineering, is a newbuilding and repair yard capable of handling offshore support vessels, tugs and workboats of various types. Its facilities include a Rolls-Royce ship lift capable of handling vessels up to 394 feet, 4,000 feet of quay for alongside repairs, and eight dry repair berths.
BUSY AT GRANDWELD
This past year, Grandweld completed the construction of 17 vessels. The shipyard’s latest projects include advanced crew boats, dive maintenance and support vessels, and work crane boats for a who’s who of Middle East energy firms and offshore contractors.
Grandweld, which has been operating from its Dubai base since 1984, specializes in vessels custom built to conduct complex operations in the region’s challenging offshore environment.
These range from three recently delivered work crane boats for Kuwait Oil Company – optimized for duties such as heavy lifting, oil-pollution control, SPM hose handling, and supply to remote areas – to two modified 42-meter-long crew boats (FNSA-3 and FNSA-4) for Fujairah National Shipping Agency. The latter vessels are capable of speeds in excess of 30 knots and customized to execute operations such as security duties, fast transportation of offshore personal and cargo, and the rapid supply of fuel and freshwater.
“The Middle East is a unique environment, with unique challenges and opportunities,” says Jamal Abki, General Manager Grandweld Shipyards. “We have a history of producing vessels that excel here. We use that understanding to continually enhance our offering, while building new relationships with international clients who can benefit from our expertise when it comes to meeting their own exacting requirements.
“Our integrated proposition is efficient, flexible and modern, while our in-house engineers and project managers are world class. In addition, we invest heavily in research and development to enhance our own designs, as well as using respected external designers when desired. This ensures our vessels are leading the way in operational efficiency, reliability and performance – something the industry clearly appreciates.”
Further noteworthy deliveries over the last months include three 34.3m aluminum crew boats to Jana Marine Services, a 50m Dive Maintenance & Support Vessel to Abu Dhabi National Oil Company (ADNOC), and the 42m crew boats Stanford Volga and Stanford Niger, which are capable of carrying 83 people at speeds of 25 knots.
“It’s an exciting time for the business, and our customers,” concludes Jamal Abki. “As the offshore trend points towards more optimized, complex vessels, our knowledge and experience allows us to respond with advanced newbuilds that deliver added performance and competitiveness for our clients.
“We’re now looking forward to building on our leading market position over the space of the next 12 months, and beyond.”
Meanwhile, Gulf ship repairers are all cautiously optimistic on potential business from Iran. However, legal experts specializing in sanctions are urging the utmost caution. The latest diplomatic fall-out between Saudi Arabia and Iran will certainly not have helped.
NEW DESIGN FROM ROLLS-ROYCE TARGETS U.S., TOO
Offshore operators in the Gulf of Mexico are among those being targeted by Rolls-Royce as it introduces the first in a series of new mid-range offshore vessel designs specifically developed to meet the requirements of companies working in a low capex era. The UT 7217 is a DP2 anchor handling tug supply ship with a bollard pull of 100 tonnes which can be raised to 130 tonnes without any fundamental design changes.
Jan Emblemsvåg is Senior Vice President of Ship Design at Rolls-Royce. He says that the company’s analysis has revealed that there are already more than 600 vessels in this range which are more than 25 years old. This could be the first sector of the offshore market to generate new demand, he believes. There will inevitably be a replacement requirement at some point, he says, and the UT 7217 has been designed with operators’ likely future requirements specifically in mind.
Although the design has been developed to incorporate as much flexibility as possible and will be capable of worldwide deployment, specific offshore markets which Rolls-Royce has identified besides the Gulf of Mexico include the Middle East and the South China Sea. Vessel price will of course depend on region and shipyard, but Emblemsvåg reveals that initial indications from some Far Eastern yards lie in the $17 million to $18 million range.
The design has been developed to compete effectively with existing ships in the sector. Bollard pull is greater than the typical 70-80 tonnes, for example, and deck area – at 500 square meters – is more than the usual 450-460 square meters. There is more cargo capacity than is usual and the vessel has a launch and recovery system.
With cost constraints in mind, Rolls-Royce designers have chosen a diesel mechanical propulsion system which comprises two medium-speed C25:33L9P CD diesels of 3,000kW each, driving two US305 controllable pitch azimuth thrusters with 3.2 meter diameter propellers in nozzles. Each engine drives a shaft generator and fire pump for fire-fighting duties. There are two independent 400kW generating sets providing electrical power and two 590kW bow thrusters.
Operating flexibility will be aided by the SPS notation which will enable the vessel to carry up to 12 additional personnel besides the crew. There are 29 cabins giving a maximum of 40 on board. This means that the ship can be deployed in a wide range of tasks, including cargo supply, anchor handling, ROV operations, safety standby and maintenance and repair.
The competitive price indications are based on a Rolls-Royce equipment package including the main two-drum hydraulic winch with 200-tonne heave and 250-tonne brake rating. They also assume the diesel mechanical propulsion system. However, Emblemsvåg is well aware that some OSV operators may wish to specify other equipment and possible alternative propulsion arrangements such as a diesel-electric set-up. These, he says, can be accommodated but will obviously have an impact on price.
Other mid-range offshore vessel designs are currently being worked on by Rolls-Royce naval architects. They include a larger 150-tonne anchor handler likely to be introduced later this year. A mid-range subsea construction vessel design is also on the drawing board, intended for waters where breakeven production costs are relatively low and where energy companies will be focusing whilst the oil price stays down.
