Nippon Yusen Kaisha (NYK) Line - Experts & Thought Leaders

Knutsen NYK Carbon Carriers AS, a subsidiary of Nippon Yusen Kabushiki Kaisha and Knutsen Group, has obtained Approval in Principle from ClassNK for the design of liquified CO2 carriers that use the elevated pressure method to store and transport liquefied carbon dioxide at ambient temperature. ClassNK has carried out a design review of this ship in accordance with the Rules for the Survey and Construction of Steel Ships, 'Part N', and has issued an Approval in Principle after confirming that the ship meets the prescribed requirements. Advancing carbon storage The LCO2-EP carrier uses LCO2-EP Cargo Tank technology developed by KNCC to transport LCO2The LCO2-EP carrier uses LCO2-EP Cargo Tank technology developed by KNCC to transport LCO2 in a stable state. Since there is no need to cool LCO2 to cryogenic temperatures, it is easy to handle and potentially reduces energy and costs during liquefaction. NYK, KNCC, and ENEOS Xplora Inc. have developed a Floating Liquefied Storage Unit that combines the LCO2-EP Cargo Tank technology with the Isenthalpic Expansion Cooling & Liquefaction Process. This Process has been researched and developed in collaboration among the three companies. ClassNK has issued an AiP following a review based on the Rules for the Survey and Construction of Steel Ships, 'Part PS', 'Guidelines for the Design of Floating Liquefied Natural Gas and Liquefied Petroleum Gas Production, Storage, Offloading and Regasification Units', etc. Innovative carbon solution This FLSU is a pioneering concept that liquefies and temporarily stores CO2 that has been collected and transported as gas in an onshore facility making it ready for further transport by LCO2 carrier.  By utilising the features of the EP method, which has the potential to reduce the energy required for liquefaction, and adopting the Process, which is expected to be simpler and more compact than conventional cooling methods, it has become possible to install a liquefaction plant on a floating structure. Scaling carbon solutions Carbon Capture, Utilisation and Storage is one area that is expected to play a certain role in achieving a carbon-neutral society.  However, issues need to be addressed, such as reducing overall costs and securing land for liquefaction and storage facilities. By utilising this FLSU, the cost of CO2 liquefaction and the land area required onshore in the CCUS value chain can be reduced, expanding the possibilities for realising CCUS. Towards a greener future NYK, KNCC, ENEOS Xplora, and ClassNK will continue to contribute to realising a carbon-neutral society by examining various technologies and assessing their economic and safety aspects towards achieving a CCUS value chain.

Methane Abatement in Maritime Innovation Initiative (MAMII) announced Royal Caribbean Group, a vacation industry pioneer with a global fleet, has become the latest member to join the cross-sectoral methane abatement initiative. The company is expected to provide valuable insights and support MAMII's ongoing efforts to develop and implement effective methane emission reduction strategies across the maritime industry. Reduction of methane emissions Addressing methane emissions is a key priority for the sector; as transitional fuels such as liquefied natural gas (LNG) are increasingly adopted, pioneers are focused on the reduction of methane emissions to reduce the environmental impact of the value chain. Established in 2022, and led by Safetytech Accelerator, MAMII unites industry pioneers, technology innovators, and maritime stakeholders to develop technologies that monitor, measure, and mitigate methane emissions from LNG-powered ships. Challenges to reduce environmental impact Royal Caribbean Group joins a growing roster of members including BP, CMA CGM, GTT Royal Caribbean Group joins a growing roster of members including BP, CMA CGM, GTT, Lloyd’s Register, Capital Gas, MSC, NYK Lines, and Shell, reflecting the initiative’s broad industry engagement. Steve Price, Programme Director at Safetytech Accelerator, commented: “Methane abatement is an urgent challenge as we work to reduce the maritime sector's environmental impact. Methane’s significant contribution to climate warming makes this an issue we cannot overlook. With Royal Caribbean Group on board, we gain a partner that shares our determination to drive innovation and collaboration in addressing this critical issue.” Net zero emissions by 2050 "We are excited to join industry leaders and collaborate on the MAMII initiative, which we believe will play a critical role in information sharing and tool development needed to manage methane emissions,” said Palle Laursen, executive vice president and head of marine, Royal Caribbean Group. “We are committed to industry collaboration and partnerships like this are key to achieve Destination Net Zero, our decarbonisation strategy to reach net zero emissions by 2050.” MAMII recently published a report examining the scale of methane slip in LNG-fueled vessels and the technologies available to tackle it. The report, available here, serves as a call to action for industry leaders to join the effort in combating methane emissions.

ClassNK has issued an Approval in Principle (AiP) for an ammonia-fuelled ammonia bunkering vessel. This vessel is jointly developed by Nippon Yusen Kabushiki Kaisha (NYK Line) and LMG Marin AS (a member of the Seatrium Group). As ammonia fuel utilization is expected in shipping for decarbonization, bunkering vessels that supply fuel to ships and related equipment will play an essential role in the supply chain. Fuel engines from IHI Power Systems Additionally, a safety verification was conducted through HAZID involving relevant stakeholders This vessel is being developed jointly by NYK Line, advancing the development of ammonia-fueled vessels, and Seatrium, the largest shipyard in Singapore, with the goal of introducing it to Singapore, one of the world’s pioneering bunkering ports. This vessel is mainly designed by LMG Marin AS. It features ammonia fuel dual-fuel engines from IHI Power Systems and a bunkering boom from TB Global Technology, allowing for safe and reliable ammonia bunkering operations. Additionally, a safety verification was conducted through HAZID involving relevant stakeholders. New technology development and social implementation ClassNK carried out a review of the conceptual design of the ship based on its ‘Part N; Ships carrying liquefied gases in bulk ‘ of the Class Rules and ‘Part C-2; Guidelines for the Safety of Liquefied Gas Carriers Using Ammonia as Fuel (Edition 3.0.2) which is part of ‘Guidelines for Ship Using Alternative Fuels (Edition 3.0) and examined the result of required assessment. Upon confirming they comply with the prescribed requirements, ClassNK issued the AiP. Moreover, the latest ‘INTERIUM GUIDELINES FOR THE SAFETY OF SHIPS USING AMMONIA AS FUEL’ approved at MSC 109 last December are referred to in this AiP. ClassNK will continue to contribute to new technology development and social implementation, including safety assessments.
