ClassNK Publishes Onboard Ammonia Leak Estimates

ClassNK has published industry-first estimated leak frequencies for ammonia fuel from onboard components for ammonia-fueled ships. For new ammonia-fueled ship designs, risk assessments involve the consideration of the probability of ammonia leak from each component. However, statistical data of onboard ammonia leak have been extremely limited, making probability estimation difficult.ClassNK, in collaboration with the Research Institute of Science for Safety and Sustainability (RISS)…
HEAVY HAULER: Andreas Rolner Powers UHL Ahead

Just shy of 10 years old, United Heavy Lift (UHL) recently welcomed its 19th ship to the fleet, an F900 eco-lifter.

Ammonia Fuelled Platform Supply Vessels to Cut GHG Emissions 70%

Eidesvik Offshore will refit its platform supply vessel (PSV) Viking Energy with an ammonia dual fuel engine, targeting 2026 as the year that the vessel will operate on ammonia for Equinor, effectively cutting GHG emissions by 70% or more.Viking Energy will switch to ammonia operations, in a move that should make it the world’s first in-service vessel to adopt the fuel as a primary energy source."This conversion is made possible by the support and investment from Equinor.
Ammonia-fueled Tugboat ‘Sakigake’ to be Classed by ClassNK

ClassNK has classed the ammonia-fueled tugboat ‘Sakigake’ completed by Nippon Yusen Kabushiki Kaisha (NYK Line) and IHI Power Systems Co., Ltd. as an ammonia-fueled vessel. This is the world's first ammonia-fueled vessel for commercial use (as of August 23, 2024, according to research by NYK). The NYK Group company Shin-Nippon Kaiyosha will employ the vessel in tugboat operations in Tokyo Bay over…
Ammonia-Fueled Tugboat Ready for Operation

NYK’s ammonia-fueled tugboat Sakigake is commencing operation in Tokyo Bay.The vessel was the subject of a conversion project undertaken by NYK and IHI Power Systems, in cooperation with Nippon Kaiji Kyokai (ClassNK), and will be the world's first ammonia-fueled tugboat in commercial use.It is undertaking a three-month demonstration for NYK Group company Shin-Nippon Kaiyosha.The vessel’s predecessor…
China’s Largest Ports Suited to Green Shipping Corridors

A new study from the International Council on Clean Transportation has investigated the feasibility of establishing green shipping corridors for China’s coastal shipping.The researchers assessed whether the ships could be powered by renewable hydrogen, methanol, ammonia or batteries without the need to refuel en route. They concluded that the technological feasibility of applying renewable marine fuels on China’s coastal shipping routes is high…
World First: Machine Room Safety Accreditation for Ammonia Fueled Vessel

ICS Wants “Feebate” Solution for 2050 Targets

The International Chamber of Shipping (ICS), working with the governments of Bahamas and Liberia, is proposing a “feebate” (rewards) mechanism to ensure delivery of the IMO’s target to achieve net zero GHG emissions from international shipping by or around 2050.At the heart of the proposal is a GHG Fee, charged to ships per tonne of CO2 equivalent (CO2e) emitted, combined with a “feebate” mechanism to incentivize the accelerated production and uptake of zero/near-zero GHG marine fuels…
