Green energy requirements behind NYK’s new heavy lift pair

Japanese heavy lift operator NYK Bulk & Projects Carriers contracted Nanjing Jinling Shipyard to build two next-generation energy-saving heavy-lift vessels.

Announcing the order with the China Merchants Group subsidiary, NYK said the heavy cargo ship market has been sluggish since the collapse of Lehman Brothers in 2008, but due to the recent increase in environmental awareness, the cargo movements of wind-power plants and LNG plants have become active, and these ships are expected to meet market needs. We will maintain and accumulate the technical know-how of heavy-lift vessels by owning and operating these vessels, and as the only heavy shipping company in Japan, we will respond to the needs of plant cargo customers.

The 138m ships will have a deadweight of 12,470 tonnes and will each be fitted with a pair of 400-tonne cranes to give a combined lifting ability of 800 tonnes. They will have a single hold and hatch allowing an under deck length for cargoes of 95m and an on deck length of 110m. Therefore, long-length cargo such as wind-power blades will be able to be loaded on deck or in the hold.

The vessels will be hatch coverless, which will allow for navigation with the hatch cover open. The bridge is placed forward, so loading tall and large cargo can be performed without worry of any disruption to forward visibility during navigation. The tween deck will be the adjustable/removable type that can be changed to two levels, depending on the cargo loaded. To accommodate bulk cargo, the tween deck will be able to used as a simple bulkhead standing in the hold.

Maximum consideration is also being given to the environment in the construction and operation of this next-generation energy-saving heavy-lift vessel. With the cooperation of Japanese marine equipment manufacturers, a significant reduction in fuel consumption has been achieved compared to existing ships of the same type and the vessels meet EEDI Phase 3 requirements that will become effective in 2025, thus reducing greenhouse gas emissions in advance.

Delivery is scheduled between August 2021 and January 2022
