NYK Line and NYK group company MTI Co., Ltd. (MTI), together with the American Bureau of Shipping (ABS) and Winterthur Gas & Diesel Ltd. (WinGD), on Thursday (2 December) said they have started a joint research to optimise ship design by utilising a battery-hybrid system to aid ship propulsion and greenhouse gas (GHG) emissions reduction from vessels.

A vessel’s main-engine revolutions may increase significantly when a vessel tries to maintain its sailing speed during strong waves and winds. The phenomenon is called load fluctuation, it states.

The shaft generator may also increase the burden on the main engine. The shaft generator is connected to the ship’s propeller shaft to generate electricity within the ship as the main engine rotates.

The battery-hybrid system is a mechanism that decreases the burden that the shaft generator places on the main engine. The system supplies electricity from the battery when the load on the main engine fluctuates. 

As a result, the power that a ship can use for its propulsion can be increased, and operation of the main engine becomes more efficient. For its advantages, the system is being introduced to more oceangoing vessels.

In addition, the use of the battery-hybrid system will lead to a reduction of GHG emissions since instead of a generator, which requires oil, it can supply electricity for the operation of onboard equipment during daily operations.

In the joint research, NYK, MTI, ABS, and WinGD aim to create an integrated simulation model of ships by combining the modeling technologies of each company to maximise GHG emission reduction through use of the battery-hybrid system.

Specifically, an integrated model of an entire ship will be created by combining NYK and MTI’s modeling technologies for actual sea performance and WinGD’s modeling technology for engine plants that include batteries.

Using ABS’s advice on the evaluation of the effect of GHG reduction. NYK, MTI and WinGD will jointly design a ship in digital space and together with ABS conduct simulations of navigation using a scenario that assumes meteorological conditions in actual seas. 

By considering the issues clarified within the simulation, NYK, MTI and WinGD will further improve the simulation model to optimize ship design. 

The joint research is an epoch-making initiative in the maritime industry that has the ship users, NYK and MTI, collaborating with the marine equipment manufacturer WinGD and with the advice of the marine classification society ABS develop a digital model of a ship, perform simulations, and build a ship. 

The ship model will be verified in accordance with a modeling and simulation framework to be developed by ABS.

In the future, NYK and MTI, together with ABS, WinGD, and shipyards, will improve the accuracy of the simulation by collating the simulation results, obtained through the joint research, with the performance data of actual ships in actual seas.

NYK and MTI aim to nurture the simulation technology as a core technology in the shipbuilding plans of the NYK Group. NYK and MTI will also utilise simulations to optimize the method of operation and control of the battery-hybrid system. The joint research is the first step for such future-aiming initiatives.

PIL's LNG dual-fuel boxship “Kota Elok” arrives in Singapore on maiden call

Singapore-based Pacific International Lines Pte Ltd on Monday (20 July) said its first 13,000 TEU LNG dual-fuel container vessel, Kota Elok, recently made her maiden call to Singapore on 15 July.

As the first of 13 new 13,000 TEU vessels joining its fleet, Kota Elok is equipped to operate on liquefied natural gas (LNG) and low-sulphur fuel oil that helps reduce our greenhouse gas emissions. 

The vessel also incorporated energy-saving features and digital technologies to reduce fuel consumption and enhance operational performance, as well as a bow windshield to improve aerodynamics, contributing to improved fuel efficiency and lower emissions over the course of long-haul voyages.

“Following Singapore, Kota Elok will continue her voyage on our East Coast Service 1 (ES1) route to South America, calling at ports in Brazil, Uruguay, and Argentina before returning to Asia,” the company said in a social media post. 

Kota Elok also became PIL’s first vessel to receive Lloyd’s Register certification for compliance with the IACS UR E26 and UR E27 cyber security requirements.

Developed by the International Association of Classification Societies (IACS), UR E26 and UR E27 are mandatory cyber resilience requirements for newbuild vessels contracted from 1 July 2024.

CIMC SOE secures order for 12,000-cbm LNG bunkering vessel from Sinopec Clean Energy

China’s Nantong CIMC Sinopacific Offshore & Engineering Co., Ltd. (CIMC SOE) recently signed a contract with Sinopec (Beijing) Clean Energy Co., Ltd. to build a 12,000-cubic metre (m3) LNG bunkering vessel, according to Chinese maritime media.

The vessel is scheduled for delivery in 2028 and will support Sinopec’s efforts to expand its presence in the marine clean energy sector.

Once operational, the vessel is expected to strengthen Sinopec’s domestic coastal LNG bunkering network and help address gaps in China’s LNG bunkering infrastructure.

With this signing , CIMC Pacific Offshore Engineering’s LNG bunkering vessel orderbook is further strengthened, maintaining its leading position in the global market for small and medium-sized LNG bunkering vessels.

The contract also marked another milestone for CIMC SOE, which has seen a sharp increase in orders and business performance this year amid a surge in domestic LNG vessel demand.

ABS awards AiP to Korean institute for SMR-powered container ship concept design

Korea Research Institute of Ships & Ocean Engineering (KRISO) on Thursday (16 July) received Approval in Principle (AiP) from the American Bureau of Shipping (ABS) for its concept design of a 15,000 TEU Small Modular Reactor (SMR)-powered container ship utilising Molten Salt Reactor (MSR) technology.

KRISO said the AiP recognises the technical feasibility and safety of its concept design, marking an important milestone toward the development of next-generation nuclear-powered commercial ships.

“This achievement demonstrates international recognition of KRISO’s technological capabilities in the rapidly evolving field of nuclear-powered shipping, supporting the transition toward low-carbon maritime transport,” it said. 

Building on this milestone, KRISO will continue advancing basic and detailed ship design, paving the way for future demonstration and commercialisation of SMR-powered vessels. 

Through continued R&D and international collaboration, KRISO remains committed to strengthening next-generation maritime technologies and contributing to the safe deployment of nuclear propulsion in the maritime industry.
