Bunkering Up

Last year, General Dynamics NASSCO earned the bragging rights for building and delivering the world’s first LNG-fueled containership, the Isla Bella, to Jones Act operator TOTE Maritime. The San Diego shipbuilder capped off that technological achievement last month by delivering the 764 ft Perla del Caribe, sister ship to the Isla Bella, two months early.

The two ships were built under a contract signed by TOTE in December 2012. The investment by TOTE in the two ships was $375 million.
 
TOTE President and CEO Anthony Chiarello, says that the “Isla Bella is already serving the people and communities of Puerto Rico and we are excited to introduce the Perla Del Caribe into the trade next month.”

 

GD NASSCO designed the ships in partnership with DSEC, a subsidiary of Daewoo Shipbuilding & Marine Engineering (DSME), located in Busan, South Korea.

The design is based on proven containership-design standards and includes DSME’s patented LNG fuel-gas system and a MAN ME-GI dual fuel, slow-speed engine. The 8L70ME-GI engine was built by Korea’s Doosan Engine under license from MAN Diesel & Turbo.

Burning LNG will allow the Marlin Class ships to be fully compliant with strict emissions regulations while operating in both the North American Emissions Control Area and the U.S. Caribbean ECA.

The Isla Bella made its first trip from Jacksonville, FL, to San Juan, Puerto Rico, November 24.

ToteIslaOn January 9, TOTE Maritime Puerto Rico successfully loaded LNG bunkers aboard the world’s first LNG powered containership, MV Isla Bella. Approximately 100,000 LNG gallons transported by 12 TOTE-owned LNG ISO containers were loaded on schedule. The bunkering was conducted under strict U.S. Coast Guard oversight while Isla Bella was also undergoing cargo operations.

The LNG was transferred from the ISO tank containers using a specially developed transfer skid developed by TOTE’s partner Applied Cryogenics Technologies (ACT) of Houston, TX. The transfer skid is designed to allow four ISO tanks to be transferred to Isla Bella at once, dramatically reducing transfer time.

The LNG was sourced by TOTE’s partner, JAX LNG, LLC, from AGL Resources’ LNG production facility in Macon, GA. Genox Transportation, a specialized LNG trucking partner of TOTE, transported the fuel to Jacksonville. Pivotal LNG, a subsidiary of AGL Resources, also provided transfer expertise to TOTE Maritime with its highly trained LNG experts, ensured the operation was conducted safely and in accordance with best industry practices.

Oversight of the operation both at shipside and on shore was provided by TOTE Services, Inc. (TSI), TOTE Maritime’s sister company that manages the vessels.

“We are very pleased with the results of this initial LNG bunker event and know that the use of LNG in our Marlin Class vessels will provide unprecedented environmental benefits both here in Jacksonville and in Puerto Rico,” says Tim Nolan, President of TOTE Maritime Puerto Rico. “We are indebted to USCG Sector Jacksonville for their diligent oversight and assistance that was invaluable and helped make this event a success. Our partners ACT, Pivotal LNG and Genox were also major components of our success. Our sister company, TSI, has developed significant expertise in LNG as a Maritime fuel and ensures that our vessels operate safely and efficiently using this environmentally superior fuel.”

Applied CryoTechnologies, Inc. (ACT) is the premier equipment supplier for cryogenics in North America. ACT is proud to be the first to market with this type of bunkering equipment for the marine industry. Leveraging ACT’s innovative style and unrivaled experience in LNG equipment is sure to bring success to any LNG fueling project.

Pivotal LNG brings liquefied natural gas to companies and industries throughout the United States through reliable, flexible and cost-effective solutions.

TOTE Maritime provides safe, reliable transportation at the fastest speed possible for the Puerto Rican and related Caribbean trades.

Meanwhile, Crowley Puerto Rico Services, Inc., Jacksonville, has selected Eagle LNG Partners as LNG supplier for the company’s new LNG-powered, Commitment Class ships, which will be delivered in 2017 for use in the U.S. mainland to Puerto Rico trade. To support Crowley’s LNG needs, Eagle LNG will build an LNG plant offering a capacity of 200,000 gallons per day (87,000 gallons per day initially) in Jacksonville. The state-of-the-art facility is slated to be operational by early 2017.

The decision to partner with Eagle LNG was made by Crowley in part because of the companies’ shared commitment to the environment.

“Crowley is proud to take a leadership position in the industry’s shift to cleaner-burning, natural gas fuel solutions,” said Crowley’s John Hourihan, senior vice president and general manager, Puerto Rico services. “The partnership with Eagle LNG is an important first step in developing sustainable supply infrastructure to ensure these highly technical, environmentally friendly vessels operate to their full capability.”

“The marine sector represents a significant opportunity for LNG fueling in the U.S., and Eagle LNG is well-positioned to build the necessary infrastructure and provide the specialized logistics to facilitate this energy transformation,” said Dick Brown, CEO, Eagle LNG. “It takes companies like Crowley to lead that wave of change. Eagle LNG is proud to work with such a pioneering organization.”

“This project is an important investment in our community from both economic and environmental perspectives,” said Jacksonville Mayor Lenny Curry. “It clearly demonstrates the leadership role our region is playing in LNG development and progression, while strengthening our commitment to leaving a smaller footprint through cleaner-burning fuel.”

The supply agreement between Eagle LNG and Crowley will provide LNG fuel for the El Conqui and Taino, which are expected to be in service in the second quarter and fourth quarter of 2017 respectively.  The 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 – benefits customers have enjoyed for nearly 60 years.  The LNG plant is separate from the previously announced Eagle LNG Federal Energy Regulatory Commission (FERC) export terminal located along the St. Johns River, in Jacksonville, which will continue to focus on export markets in the Caribbean and Atlantic Basin.

DUAL FUEL BULKERS BUILT TO NEW DNV GL CLASS
ESL Shipping’s new dual-fuelled bulk carriers will not only be the first large LNG-fuelled bulkers, but the first vessels constructed to the new DNV GL rule set. Due for delivery in early 2018, the two highly efficient 25,600 dwt vessels are optimized for trading in the Baltic Sea region.

“It is fitting that the first vessels that will be constructed to the most forward looking set of classification rules are themselves at the cutting edge of maritime innovation,” says Knut Ørbeck-Nilssen, CEO of DNV GL – Maritime. “We have created these rules to be ready for the future and we have long pioneered the use of LNG as a ship fuel. To see these two come together in a double first for the industry is a remarkable moment. We look forward to working with ESL, Deltamarin, Sinotrans & CSC Qingshan Shipyard and all the project partners to make this project a success.”

“We are proud to be the world’s first shipyard applying the new and innovative DNV GL rules for a newbuilding, just two months after DNV GL has launched its new rules in October this year,” said Liu Guangyao, Deputy General Manager of Sinotrans & CSC at the Marintec China Trade Fair recently. “We appreciate the support that DNV GL has committed to provide on the project during both the design and construction phase, especially in a project with many advanced extra class notations. We are looking forward to a close cooperation and a successful delivery.”

Featuring the Deltamarin B.Delta26LNG design, the two highly efficient ships will feature dual-fuel main and auxiliary machinery, resulting in CO2 emissions per ton of cargo transported half that of present vessels. The bulk carriers will be built to the new DNV GL rules for general dry cargo ships with DNV GL ice class 1A and will have type C LNG tanks of approximately 400 m3 capacity enabling bunkering at several terminals within the Baltic region. The B.Delta26LNG has a shallow draft of maximum 10 m, an overall length of 160 m, and a breadth of 26 m.

“We are very excited to have been selected to take part in this ground breaking project,” says Morten Løvstad, Business Director Bulk Carriers at DNV GL. “Being asked to work with such an innovative team as the classification partner is a testament to the creativity and hard work that so many colleagues at DNV GL have invested in the new rule set. These vessels will set new standards for efficiency and environmental performance. They are an important step forward in showing how shipping can be a force for sustainability today and in the future.”

FIRST PURE LNG FERRY FOR GERMANY
Germany’s first LNG-fueled ferry, the MS Ostfriesland, has now been  operating for AG Ems between Emden and Borkum Island on the ecologically sensitive Wadden Sea, since June 2015.

Originally built in 1985, the vessel was converted to dual fuel propulsion in a conversion that saw it fitted with a complete new aft end, construction of which got underway at German shipyard  Brenn – und Verformungstechnik Bremen GmbH while the ship remained in service.

The new aft section, which extended the vessel’s length from 78.7 m to 93 m, houses the new machinery space and LNG fuel system/tank with the vessel now being propelled by two electrically powered Schottel STP Twin thrusters, each rated at 1,150 kW at 1,480 rpm.

While the prime movers are two 6-cylinder Wärtsilä 20DF dual-fuel generating sets, for navigating within harbors, the vessel uses two Mitsubishi auxiliary generators.

Switching to LNG fuel means providing against various unlikely malfunctions, such as an ignition failure resulting in an unburned mixture of gas and air in the exhaust. This could cause uncontrolled combustion and an increase in pressure the next time ignition takes place, putting a substantial strain on the pipe components.

To protect against this, the Mitsubishi auxiliary generators are protected by a Q-Rohr flameless venting system by German manufacturer Rembe GmbH that ensures that the reaction is vented directly at the exhaust.

Both the flame and the pressure are absorbed by the stainless steel mesh filter of the Q-Rohr, providing optimum protection for the pipe components and the environment.

DNV GL uses drone for surveys without scaffolding

“We have been looking at ways we could help our customers by accelerating the survey process,” says Cezary Galinski, Manager of the DNV GL – Maritime classification flying squad based in Gdansk. “Camera equipped drones are now much more widely available and affordable, and by using them for a first screening we can identify areas that require closer inspection quickly and without extensive staging, which can be both costly and time-consuming.”

Using drones to visually check the condition of remote structural components has the potential to significantly reduce survey times and staging costs, while at the same time improving safety for the surveyors.

The tests used a camera-equipped drone to visually evaluate structural components through video streamed to a tablet. One surveyor operated the drone, while a second checked the video feed in real time. The stream was also recorded for review and documentation purposes.

Equipped with a powerful headlight, the drone was able to produce a video of sufficient quality for initial inspection purposes. In the event any damage is detected, a traditional close-up survey may still be required.

“We used a modified off-the-shelf drone for our tests,” says Mr. Galinski. “Because there are currently no drones formally certified as explosion-proof commercially available, we performed a risk assessment. Of course, before the drone operation started, we also ensured that the cargo tank was gas-free and certified for safe entry.”

“Our next step is to work with a more advanced tailor-made drone in early 2016,” says Mr. Galinski. “We are also developing a special guideline for performing drone-based surveys. This could open the way to remote or even autonomous inspections being carried out as part of our survey scheme in the near future.”

DNV GL has a longstanding R&D program working on developing advanced inspection technologies, including the IRIS system which can automatically associate photos onboard a ship with a 3D model of the vessel’s structure.

“Using a drone in combination with a system like IRIS could be very beneficial to our customers,” says Dr. Pierre C. Sames, Director of Group Technology and Research. “We have already demonstrated the ability to place images within a 3D model and furthermore to assess the individual findings. These are the first steps towards an automated survey process which might include using a drone to make the initial survey, taking the images generated and then running them through an algorithm to determine the hull condition.”

DNV GL releases new guideline on cargo liquefaction

Many common bulk cargoes, such as iron ore fines, nickel ore and various mineral concentrates, may be subject to the phenomenon, in which a soil-like material is abruptly transformed from a solid dry state to an almost fluid state.

If liquefaction occurs on board a vessel, the stability will be reduced due to the free surface effect and cargo shift, possibly resulting in capsizing of the vessel. The ship structure may also be damaged due to increased cargo pressures.

DNV GL says there are some distinct and disturbing features of accidents caused by cargo liquefaction.

First, the accidents happen very fast. The period of time from when liquefaction is detected, if it is detected at all, until the vessel has capsized could in some cases be only a few minutes. This leaves very little time for remedial measures. It also leaves very little time for safe evacuation of the ship, and such accidents are often associated with tragic losses of crew members.

Second, an accident on one vessel is often followed by a new accident, or near-accident, on other vessels that have loaded similar cargo at terminals in the same area.

DNV GL’s new guideline aims to raise the awareness of the risks of liquefaction and describes mitigating actions to reduce these risks.

“Cargo liquefaction is probably now the most significant factor in lives lost at sea for bulk carriers,” says Morten Løvstad, Business Director of Bulk Carriers at DNV GL. “While the general safety level of modern bulk carriers has been significantly improved over the last decades, recent incidents have shown that cargo liquefaction remains a major safety issue. Since 2009, at least six ships of more than 40,000 dwt have been lost to suspected liquefaction of cargo. These incidents have shown that cargo liquefaction is an issue that has not been sufficiently dealt with, and concerned owners and operators have contacted us for support and advice.

“With this guideline we wanted to help our customers by not only increasing awareness and building competence around the phenomenon, but also to offer some strategies, both in design and operation, to reduce these risks.”

The guideline focuses on both the operational and design aspects of cargo liquefaction.

In daily operation, recommendations to reduce the risk of liquefaction include:

The design guidelines look at the potential of carrying cargoes with high moisture content onboard specially constructed or fitted ships, in compliance with the IMSBC Code. Such vessels can remain safe both from a stability and strength point of view even if the cargo liquefies or shifts.

“Under the IMSBC code such vessels must have permanent structural boundaries or specially designed portable divisions to confine any shift or liquefaction of cargo, but detailed requirements are lacking,” says Mr. Løvstad. “It is clear, however, that stability and structural strength have to be specially considered, and our guideline sets out criteria for them, based on DNV GL procedures and rules.”

The guideline also examines how and why liquefaction can occur, which bulk cargoes are subject to liquefaction risks, explains the Transportable Moisture Limit (TML) and presents the effect of liquefaction on a vessel. The aim of the guideline is to provide ship designers, shipyards, shipowners and other stakeholders in the shipping industry a basis to assess the risks and begin the process of making their vessels and their operational processes safer when it comes to the risks of liquefaction.

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.
