Leading Classification Society ClassNK granted an Approval in Principle (AiP) based on its Rule Part N which adopts IGC Code and its Guidelines for Ships Using Low-Flashpoint Fuels to Kawasaki Heavy Industries, Ltd (KHI) for their LPG fuel supply system.

Utilizing the expertise from the design and construction of LPG carrier, LNG carrier, and LNG fueled ships as well as the design and production of marine engines, KHI has developed the LPG fuel supply system. In consideration of LPG fuel’s property and the related rules, ClassNK has carried out the verification on the system from the viewpoint of minimizing risks to vessels, crew, and the environment. Following confirmation that the design of KHI’s LPG fuel supply system met the prescribed standards, ClassNK has issued the AiP.

The main features of the design announced by KHI are as follows.

(1) Cyclical system design that is compatible with propane and butane and circulates LPG in a pressurized state capable of usage at normal ambient temperature
(2) Establishing a highly safe control system by implementing risk assessment based on the IGC code
(3) System configuration applicable to merchant ships other than LPG carriers

Speaking on the occasion, Mr. Hayato Suga, Corporate Officer and Director of Plan Approval and Technical Solution Division said “ClassNK is glad to have granted the AiP on KHI’s innovative design for the system to use LPG as ships’ fuel which tackles with the reduction of air pollution and climate changes due to emission from ships. Through our professional third-party verification on cutting edge technology, we will continue support the spread of alternative fuel options including LPG.”

In September, NYK signed a multi-year time charter contract with Osaka Gas International Transport Inc., a Daigas Group company, for a new LNG carrier.

This vessel, named “Grace Freesia,” comes equipped with a WinGD-made dual-fuel slow-speed diesel engine, i.e., X-DF diesel engine that has superior fuel-consumption efficiency and can operate on marine gas oil or boil off gas stored in the cargo tank.

The carrier also features a re-liquefaction system that can use surplus boil-off gas efficiently. The cargo tank is a 174,000 cubic meter capacity membrane-type tank that makes use of advanced insulating materials to suppress the boil-off rate in the cargo tank and realizes significantly more efficient, economical, and environmentally friendly operation.

By utilizing its experience and network cultivated as a world-scale LNG-carrier owning-and-managing company, NYK is contributing to Japan’s stable energy supply.

<Vessel Particulars>

Length overall: 297.160 meters
Breadth: 46.40 meters
Cargo tank capacity: 173,956 m3
Main engine: X-DF engine
Shipbuilder: Hyundai Samho Heavy Industries Co., Ltd.
Flag: Bahamas
Delivery: 2022

In February 2021, NYK released the “NYK Group ESG Story,” which aims to further integrate ESG into the company’s management strategy and promotes activities that contribute to the achievement of the SDGs through business activities. In March this year, NYK released the updated “NYK Group ESG Story 2022,” which introduces initiatives for integrating ESG into the Group’s management strategies set forth in the “NYK Group ESG Story” and provides a partial explanation of the Group’s sustainable growth strategy from a long-term perspective.

To strongly promote ESG management, the NYK Group will encourage new value creation as a sustainable solution provider through a business strategy that includes the transportation of LNG, which is expected to be a low-carbon bridging fuel prior to the transition to future zero-emission fuels.

Damen Shipyards delivered a complete equipment package for the multipurpose vessel ENDAM. Owned by the Korean Marine Environment Management Corporation, the newbuild combines emergency oil spill recovery activities with maintenance dredging tasks.

With a 4,100 m3 hopper hold, the vessel was built by HJ Shipbuilding & Construction at its Busan yard and designed by KmsEmec. The mission equipment package provided by the Damen Technical Cooperation team included a 15 m rigid oil sweep arm with a dedicated pump and handling crane for the emergency oil spill recovery functionality, and a complete turnkey dredging system, which was designed specifically for the vessel.

Turnkey dredge package

The turnkey dredge package consisted of both loading and discharging equipment, a hydraulic system, dredging control system and various drives. A 900 mm trailing suction pipe, designed to dredge at a maximum depth of -30m, is hoisted by three dedicated gantries and their hydraulically operated winches. All the trailing suction pipe components are located starboard aft.

A Damen dredge pump, type BP9075HD, completed the dredge pipe arrangements. The highly efficient slurry pump is designed for both suction dredging, as well as discharging over the bow using the bow coupling unit or rainbow nozzle. This hopper discharging equipment, including 12 bottom dump valves which Damen designed, were all part of the dredge package. Furthermore, dredge valves in various pressure stages were delivered for the suction and discharge piping. Dedicated dredging instrumentation completed the package. This is crucial to monitor and visualise the dredging process and to optimise the dredging operations.

Component integration

Due to the DTC team’s extensive experience in component integration at non-Damen yards, the large system parts were delivered from the Netherlands and integrated effortlessly. As well as the mission equipment, the delivery scope included a hydraulic system. This is a logical choice as the dredging equipment is its main user. Additionally, a 3,500-kW electric dredge pump drive and a 1,000-kW electric jet water pump drive were shipped to Korea. The delivery was completed with a full set of spares and Damen also carried out the commissioning and training on board.

The vessel was named ENDAM, which means ‘the fence that protects you’ in the Korean Jeju dialect. A festive handover ceremony took place in the summer and ENDAM has successfully started operating along the Korean coast.

MOL DPTC is the first DP training centre in Japan to be accredited by the Nautical Institute to provide NI-approved dynamic positioning training courses.

The delivery includes a K-Sim DP Anchor Handling simulator to support advanced offshore training, as well as four KONGSBERG K-Pos DP Basic desktop simulators for basic DP training, including instructor stations to manage the exercises.

As part of the contract, KDI will also deliver a newly developed hydrodynamic ship model; a digital version of the DP2 cable laying vessel KDDI Cable Infinity, owned by Kokusai Cable Ship Co., Ltd.

The simulator will be used to provide NI-approved DP training courses for MOL crew and the company’s customers. It will also be used to develop and provide customized training for cable-laying operations, offshore wind power related projects, or other offshore projects that utilize dynamic positioning systems. Furthermore, the simulator will also be made available for research and consulting services to serve the wider maritime industry.

The NI training scheme for obtaining a Dynamic Positioning Operator certificate has formerly been a time-consuming process, involving onshore courses and ‘real life’ DP watch keeping experience on DP vessels.

The K-Sim DP Class A simulator is approved to be used for DP Seatime Reduction training under the Nautical Institute’s training scheme. K-Sim integrates with an advanced physics engine which, in addition to hydrodynamic modelling allows vessels, objects and equipment to behave and interact realistically. This is extremely important for making competence training adaptable to real-life operations.

Aditionally, KDI has signed a five-year Long-Term System Support Program contract with MOL Marine and Engineering Co. Ltd. to keep the simulator maintained in top condition. This ensures hassle free operations and support, and any new system updates will be actively managed by KDI.

“This contract signifies recognition of Kongsberg Digital’s Maritime Simulation and DP technologies by one of the largest shipping companies in the world,” says Andreas Jagtøyen, Executive Vice President Digital Ocean, Kongsberg Digital. “The K-Sim DP Class A simulator has the necessary fidelity and realism required for engineering, training and mission planning, as well as assessment of existing and new crews, where various challenging operations can be studied, evaluated and optimized safely in the simulator.”

“We Installed Kongsberg DP simulator and were able to open a quality DP training center in Tokyo, Japan” says Mr. Nakashima Takashi, President, MOL Marine and Engineering Co., Ltd. “We believe that MOL Group can contribute more and more to the offshore wind power business, which is in high demand in Japan.”
