Nakilat retrofits QMax’s main engines to LNG fueling

 

The project involved retrofitting two MAN B&W S70ME-C HFO-burning engines in the chartered Q-Max vessel Rasheeda with gas-burning M-Type Electronically Controlled – Gas Injection (ME-GI) Systems, which have now been successfully commissioned.

The retrofit modification meets all current and foreseen global emissions regulations.

Nakilat-Keppel Offshore & Marine (N-KOM) carried out the conversion at its Erhama bin Jaber Al Jalahma Shipyard facilities in the major Qatari port of Ras Laffan Industrial City.

The project collaborators, including MAN PrimeServ, installed the ME-GI system on the vessel at the shipyard in June 2015. The partner for the ME-GI fuel supply system is TGE Marine Gas Engineering GmbH,

Christian Ludwig, Head of Retrofit and Upgrades, MAN PrimeServ, said: “This is a fantastic milestone in our company’s history. It is a lighthouse project, and there has been a remarkable partnership and cooperation through this historic conversion. Our ME-GI order book now stands at 140 orders – for different vessel sizes and applications, which we see as a compelling case for our technology to be designated the industry standard.”

Nakilat Managing Director Eng. Abdullah Al-Sulaiti, said, “The success of the ME-GI project is the culmination of years of cooperation with Qatargas, RasGas and MAN Diesel & Turbo as turnkey project manager. In late 2013, Nakilat worked with our charterers to implement a pilot conversion on Q-Max Rasheeda, the first retrofit ME-GI project ever to be implemented in the marine industry. This is a milestone moment for all involved parties.”

MAN Diesel & Turbo reports that the vessel’s ME-GI units have displayed a seamless change between fuel-oil and gas operation – a key characteristic of the ME-GI technology.

The Qatar fleet comprises 14 Q-Max and 31 Q-Flex LNG carriers, all using dual MAN Diesel Turbo’s S70-ME low-speed diesel engines for propulsion.

THE ME-GI ENGINE

The ME-GI engine gives shipowners and operators the option of utilizing oil or gas fuel depending on relative price and availability, as well as environmental considerations.

The ME-GI uses high-pressure gas injection, allowing it to maintain the attributes of MAN B&W low speed engines that have made them the default choice of the maritime community.

The ME-GI is not affected by the derating, fuel-quality adjustment or methane-slip issues that have been seen with other dual-fuel solutions.

MAN Diesel & Turbo sees significant opportunities for gas-fueled tonnage as fuel prices rise and exhaust-emission limits tighten. Research indicates that the ME-GI engine delivers significant reductions in CO2, NOx and SOx emissions, with its negligible methane slip makes it the most environmentally friendly technology available.

An ME-LGI counterpart that uses LPG, methanol and other liquid gases is also available and has already been ordered.

German owner to convert containership to LNG fueling

Funding was provided through the federal program Mobility and Fuel Strategy which promotes the maritime use of LNG as an environmentally friendly fuel.

“For many years our shipping company has been committed to ‘Green Shipping’ – through the development and implementation of more efficient alternative propulsion systems,” said Gerd Wessels, Managing Owner of Wessels Reederei GmbH. “With the conversion to LNG we and our partners are showcasing our technical expertise and demonstrating practical environmental solutions for the merchant marine industry.”

Wessels Reederei has been investigating the conversion for the past two years, in collaboration with the main engine manufacturer, MAN Diesel & Turbo, and gas specialist TGE Marine Gas Engineering GmbH.

Delivered in 2011 by China’s Jiangdong Shipyard, Wes Amelie is a modern 1,000 TEU containership that operates in the North Sea and Baltic.

Wes Amelie has 23 sister ships, 16 of them structurally identical, and in selecting the vessel for conversion, special attention was paid to the scalability of the engineering services as well as the development costs, significantly reducing the costs for follow-up projects. continent.

One reason for the providing of funding for the conversion by BMVI is that it contributes to resolving the “chicken and the egg” problem of LNG fuel availability vs. demand by being a a demand-generating flagship project.

Wessels Reederei says that “due to the long delivery time for LNG tanks,” the conversion will begin in fourth quarter 2016, with full operational usage of LNG as fuel planned for early December 2016.

Are you ready for a TOWBoT?

 

Drone technology is also finding applications in the maritime industry for the same reasons.

“We see opportunities to use robotics to reduce the danger to crews posed by riskier tug operations, and to reduce costs in some cases,” says Mike Fitzpatrick, President & CEO of Vancouver-based naval architectural firm Robert Allan Ltd. “Control and digital communication technologies developed for drones used in other sectors have reached the point where its transfer to our industry is completely feasible, and is perhaps overdue. These technologies have been used in smaller autonomous surface vessels (ASVs), autonomous mine trucks, autonomous underwater vehicles (AUVs) and aerial drones for years.”

Robert Allan Ltd. (RAL) has just unveiled an autonomous tug concept called the RAmora. The first in the company’s TOWBoT (Tele-Operated Workboat or Tug) series, the RAmora 2400 is a versatile towing platform designed primarily for ship assist and berthing operations. With a bollard pull of 55 tonnes, the RAmora 2400 features a hybrid propulsion system and ample battery storage capacity to enable extended operation even in potentially hazardous environments such as LNG terminals or fire-fighting situations.

The RAmora is operated remotely by a captain on a command tug using a console equipped with live video and other positioning information.  “It is also possible,” explains Fitzpatrick, “for the RAmora captain to operate RAmora away from the console by a bellypack controller when in close visual range.”

The control system design was developed in partnership with International Submarine Engineering of Port Coquitlam, Canada, and is derived from proven remotely operated vehicle, autonomous underwater vehicle and surface vessel applications.

 

RAmora is fitted with Voith Schneider Propeller (VSP) drives arranged in a fore/aft configuration and its hull form, designed for high stability and good seakeeping performance in waves, is the product of extensive development work including CFD and towing tank testing. Yet, being a TOWBoT with no need for a conventional wheelhouse, crew accommodations, domestic systems or lifesaving equipment, RAmora is simpler and more compact than any conventional tug of comparable performance.

 

Other features incorporated into the RAmora include off-ship fire-fighting (fi-fi) capability classed to “Fi-Fi 1”, two 1,200 m³/hr fire monitors supplied by electrically-driven fire-fighting pumps, a crane boom that can be optionally fitted with a smaller 600 m³/hr fire monitor and camera.

RAmora can be used for ship handling operations that can put crew at risk, for operations at terminals where ship handling may be required in emergency  situations in hazardous environments, or as a fire fighting asset that can work in close proximity to a toxic fire, or in a restricted space, for extended periods with no risk to crews.

But don’t expect the RAmora to appear in the market overnight. “While the core control and communication technologies are mature,” cautions Fitzpatrick, “there is a lot of work to be done to get to the point where industry, class and regulatory authorities are completely satisfied that safety and reliability meet or exceed what is presently achieved with conventional tugs for the type of ship handling operations that RAmora is intended for. That process could take several years, and we need to be realistic about that. On the other hand, building a prototype RAmora could be done in as little as one to two years since there are no major technological obstacles. We see it as more of an exercise in integrating existing technologies. In many respects, without the normal outfitting required for a crewed tug, RAmora is simpler to build and has considerably fewer systems.”

Sulfur in Danish air halved since ship fuel limits imposed

 

Evidence for the dramatic reduction comes from measurements taken by a technologically advanced “nose” or “sniffer” installed on the Great Belt Bridge to monitor ships’ compliance with the new rules. Installed by the Danish Ministry of the Environment and Food, the sniffercan detect the use of illegal fuels by ships sailing under the bridge. 

The first air measurements performed by the sniffer show that 98% of ships comply with the sulfur standards and, according to a new report by the Danish Center for Environment and Energy at Aarhus University (DCE), the total content of airborne sulfur has been reduced by up to 60% since the new year. 

“Sulfur and particles are harmful to people, so it is good news that the new environmental requirements are having an effect. As the first country in the world, Denmark has implemented new technology to monitor ships’ emissions and ensure full compliance with the requirements. Significant economic savings are possible by circumventing the law, so monitoring and enforcement are important to avoid harmful pollution from the ships and an unfair competitive situation for the law-abiding shipowners,” says Minister for Environment and Food Eva Kjer Hansen.

The additional costs of fuel depend on the size and speed of the ship, but they can be up to DKK 1 million for a round trip journey between the English Channel and Baltic Sea.

Monitoring at the Great Belt Bridge is not the only measure. A sniffer is also installed on a small plane that monitors ships sailing along major shipping routes through Danish waters. If the sniffer measurements show that a ship is using illegal fuel, the authorities at the next port are notified so that they can stop the violation.  

Chalmers University developed the sniffer technology. The Ministry of the Environment and Food is funding the monitoring efforts, which cost DKK 6.3 million. 

“The Danish shipowners fully support the new requirements and there is a positive, close cooperation regarding monitoring and enforcement between the Ministry of the Environment and Food and the Danish Shipowners’ Association, under the auspices of the Partnership for Green Shipping,” says Director General Anne H. Steffesen of the Danish Shipowners’ Association. “Effective international enforcement is crucial to the industry and ensuring equal competitive conditions for all. Remote monitoring from bridges and aircraft can be an important part of ensuring compliance with the rules – especially when stricter requirements take effect worldwide by 2025, making international enforcement even more important.”

A joint international effort to ensure that ships comply with environmental requirements is important. Therefore, Denmark is currently working in the EU and the UN International Maritime Organization to ensure effective and uniform monitoring and enforcement.

Rotterdam could get LNG Hybrid Barge

A floating energy plant, the LNG Hybrid Barge is designed to provide ships in port with clean power—an alternative to providing ship’s power by plugging into the city grid or producing electricity via generator sets or main engines. During winter season the LNG Hybrid Barge will be able to deliver heat to factories or to the central city heating system in addition to electricity.

BMS is the owner of the LNG Hybrid Barge and provides services to charter out the barge.  BMS Managing Director Dirk Lehmann, says, “The LNG Hybrid Barge is the first flexible solution supplying clean LNG energy to cruise ships during summer season and providing the flexibility of generating electric energy and heat into a public grid system or industrial users during winter season. We see this advanced flexible solution as an opportunity for Rotterdam and other international ports.”

Primarily the LNG Hybrid Barge will support cruise ships moored in Rotterdam, traditionally key clients of KOTUG. KOTUG will move the LNG Hybrid Barge and will provide commercial, technical and operational management of the LNG Hybrid Barge.

KOTUG CEO Ard-Jan Kooren, says, “As a leading towage company and with our strong focus on innovative technical and environmental solutions, we strive for reducing our environmental footprint and encouraging our suppliers, clients, business partners and stakeholders to reduce their environmental impact. We are proud to be working with innovative partners like Becker Marine Systems and we look forward to making together a significant step in supporting our clients in a greener, safer and more efficient operation.”

This new, innovative concept and unique cooperation has also drawn significant attention from key players in the LNG market, like Cruiseport Rotterdam, Dutch National LNG Platform and Shell. Arjan Stavast, Shell’s Downstream LNG Business Development Manager for Europe says, “We see the LNG Hybrid Barge as a unique solution for the maritime industry. We will follow these developments closely as we do believe that the delivery of electricity through LNG is possible for (cruise) ships, factories and cities, while not having to invest heavily in additional electricity infrastructure.”

“We are delighted to learn about this initiative and are looking forward to welcome the LNG Hybrid Barge in Rotterdam,” says Mai Elmar, Executive Director of Cruise Port Rotterdam.

Gerrit van Tongeren, Chairman of the Dutch National LNG Platform, says the initiative “is another great and unique example of how (in their respective fields) leading maritime companies can work together in the entire LNG chain and together strive to get LNG introduced in the market and contribute to a cleaner and greener environment. We therefore follow and support this initiative and wish all parties good luck in achieving the objectives.”

Coast Guard nabs another narco sub

Around 15,000 pounds of cocaine were seized and four suspects aboard the self-propelled semi-submersible vessel were detained.

The incident took place in international waters of the Eastern Pacific Ocean off the coast of Mexico. A CBP Office of Air and Marine P-3 Maritime Patrol Aircraft tracked the 50-foot vessel while on routine patrol in the region. The Coast Guard Cutter Bertholf, also on patrol in the area, was alerted to the suspicious vessel.

The cutter launched two Over-the-Horizon Long-Range Interceptor boat crews to intercept and board the vessel. Upon approach of the boarding teams, four suspected smugglers exited the hull. Boarding team members retrieved bales and loose bricks of contraband from the semi-submersible that tested positive for cocaine.

 

Bertholf and Narco Sub

 

narcosub 300“Every load of cocaine stopped at sea impacts the operation of transnational criminal organizations that spread violence, instability and death wherever they operate,” said Lt. Cmdr. Joseph Giammanco of the 11th Coast Guard District law enforcement branch. “It takes a dedicated, well-coordinated team to accomplish this dangerous and important mission. We’re proud of our crews and thankful for our strong partnership with Customs and Border Protection.”

The seized contraband is worth an estimated $227 million.

After the suspected smugglers and contraband were removed from the semi-submersible the craft was sunk as a hazard to navigation.

The previous month, on July 18, the crew of the Coast Guard Cutter Stratton from Alameda, CA, apprehended four suspected smugglers and seized 275 bales of cocaine worth more than $181 million wholesale from a self-propelled semi-submersible. In this incident, the 40 ft craft had been detected by U.S. Navy maritime patrol aircraft detected the 40-foot semi-submersible vessel more than 200-miles south of Mexico.

After removing 12,000 pounds of the narcotics aboard, the crew of Stratton attempted to tow the vessel to shore as evidence; however, the semi-submersible began taking on water and sank. Approximately 2,000 pounds of cocaine that had been left in the narco sub to stabilize it during the towing evolution sank in over 13,000-feet of water and is unrecoverable.

Up until the most recent incident involving the Bertholf, the July 18 semi-submersible seizure was the largest recorded semi-submersible interdiction in Coast Guard history.

There have been more than 25 semi-submersible interdictions in the Eastern Pacific Ocean since November 2006 when the first documented interdiction occurred.

The vessels are extremely difficult to detect and interdict because of their low-profile and ability to scuttle.

Narco sub seizure by Bertholf came not long after interdiction by Stratton shown in this video

VIDEO: Crowley’s LNG fueled ConRo now 25% complete

 

First steel for the ship was cut in October 2014 and it is now 25 percent complete.

“Week by week, we have watched the pair of Commitment Class ships begin to take shape,” said John Hourihan, senior vice president and general manager, Puerto Rico/Caribbean liner services. “It’s been incredible to watch. Once fully constructed, these new vessels will embody superior technology and construction and, while we are anxious to get them into service for our partners in Puerto Rico, we are thrilled that they are coming together on schedule.”

“The entire team at VT Halter Marine is pleased and proud to be partnered with Crowley in the construction of these magnificent ships,” said VT Halter Marine President and CEO Jack Prendergast. “It is a pleasure to see the hard work of the Crowley/Halter team come to fruition.”

The ships will be 219.5 meters long, 32.3 meters wide (beam), have a deep draft of 10 meters, and an approximate deadweight capacity of 26,500 metric tons.Cargo capacity will be approximately 2,400 TEUs (20-foot-equivalent-units), with additional space for nearly 400 vehicles in an enclosed Roll-on/Roll-off garage.

Each ship will be powered by an MAN B&W 8S70ME-GI8.2 main engine and three MAN 9L28/32DF auxiliary engines fueled by LNG.

The ship design is provided by Wärtsilä Ship Design in conjunction with Crowley subsidiary Jensen Maritime, a leading Seattle-based naval architecture and marine engineering firm.

The Commitment Class, Jones Act ships will replace Crowley’s towed triple-deck barge fleet, which has served the trade continuously and with distinction since the early 1970s. These new ships will offer customers fast ocean transit times, while accommodating the company’s diverse equipment selection and cargo handling flexibility. El Coquí and Taíno are scheduled for delivery second and fourth quarter 2017 respectively.

Designing, building and operating LNG-powered vessels is in line with Crowley’s overall EcoStewardship positioning and growth strategy. The company formed an LNG services group earlier this year to bring together the company’s extensive resources to provide LNG vessel design and construction management; transportation; product sales and distribution, and full-scale, project management solutions.

Five paths to greener coastal shipping

The program was launched by DNV GL and now also involves 25 partners from the Norwegian maritime industry and the Norwegian authorities.

The pilot projects include several different ship types, and infrastructure with an emphasis on alternative fuel concepts.

“When we launched the Green Coastal Shipping Programme, we said we wanted to make Norway a world showcase for green coastal shipping. With these five pioneering pilot projects we are well on our way,” says Program Director Narve Mjøs.

CargoFerry plug-in hybrid: Shipping company Nor Lines will lead the first pilot project, CargoFerry Plug-in Hybrid, which aims to develop a cost-effective and profitable short-sea containership powered by a plug-in hybrid LNG/battery propulsion system. It is a short-sea containership concept with a zero-emission solution during port sailing and operations. After developing the technical concept, the project partners will calculate the vessel’s environmental footprint and carry out a cost/benefit analysis.

Next-generation green shuttle tanker: Teekay Tankers will lead the second pilot project, which will investigate technical solutions for utilizing batteries and VOC (Volatile Organic Compounds) in a shuttle tanker. Battery technology has not been used on this vessel type yet and the project will explore how it could potentially help to optimize operations and reduce the need for installed power. The project partners will also look at the possible use of batteries as a “spinning reserve.”

After assessing the economic and regulatory feasibility of battery-powered shuttle tankers, the project will review new technological solutions for utilizing VOC (volatile organic compounds) produced on board by capturing and condensing the recoverable gases produced during offshore loading. Using the liquid VOC for onboard power generation could reduce total fuel consumption and the environmental impact of the vessel. As VOC are generated during offshore loading, using them as an energy source could offer an additional environmental benefit to reduction in total demand for fuel.

Hybrid ocean farming vessel: The third pilot project, by ABB and the Cargo Freighters’ Association, aims to define an optimized hybrid propulsion system for more energy efficient operations with greater redundancy.

Conversion of cargo carrier into battery-hybrid LNG carrier: This project aims to develop a cost-efficient LNG distribution concept with a hybrid LNG/battery propulsion solution and zero-emission port operations. Converting an existing vessel may provide a cost-effective option for small LNG carriers. The project owners Øytank Bunkerservice and the Norwegian Gas Association will lead the way in developing the technical concept, calculating the environmental footprint and carrying out a cost/benefit analysis.

Pioneering green port project: The fifth pilot project has the objective of developing a low-energy-consumption port with a minimal carbon footprint. Some of the technologies being employed to achieve this include electric heavy-duty vehicles and cranes. The green port will also be equipped with smart gates, offer cold ironing services and charging stations for plug-in hybrid ships.

Risavika Harbor in Stavanger will take the lead in the green port project, developing the technical concept, undertaking a cost/benefit analysis, calculating the environmental footprint and presenting a plan for further development of the concept.
