Along with its partners MTI and Elomatic, Nippon Yusen Kabushiki Kaisha (NYK) Line has concluded the concept design phase of a new capesize bulk carrier and a very large crude oil tanker (VLCC).

This design is part of Phase 1.5 of a project that is focused on the development of a liquefied natural gas (LNG)-fuelled vessel that can be transformed into an ammonia-fuelled vessel or an ammonia-fuel-ready LNG-fueled vessel (ARLFV).

Under the Phase 1.5 concept design, the three entities worked together to address various issues, as well as studied the fuel-tank layout and other specifications of the ship to present a concept design with features that are viable, functional and safe.

The ARLFV vessels are anticipated to have a conversion-cost reduction of 12% for the capsize bulk carrier and 25% for the VLCC, when compared to conventional LNG-fuelled vessels.

The partnership will now advance with the actual design of an ARLFV, working with shipyards and marine equipment manufacturers based on the concept design.

Ship specifications for the vessel building, including overall length and width, load capacity, voyage distance and ship speed, are all covered under the concept design.

Last September, the trio announced the project to develop an ARLFV as a ‘next bridge solution’ to develop zero-emission vessels.

In March, the companies concluded the concept designs of a pure car carrier and a post-panamax bulk carrier as part of phase one of the project.

Separately, NYK Group company NYK Bulk & Project Carriers (NBP) entered a memorandum of understanding (MoU) with Chilean state-owned company Corporación Nacional del Cobre de Chile (Codelco) for a joint study of decarbonised transportation of copper products.

The partnership will assess and develop next-generation fuel technologies as well as study the use of decarbonised vessels for the oceangoing transport of copper products.
