One of the world’s greenest tug construction programs kicks off, says an article on Offshore energy.
Tugboat build program
HaiSea Marine (HM), a joint venture partnership between the Haisla First Nation and Seaspan ULC, has announced the official start of its battery-powered and low emissions tugboat build program.
Once delivered in 2023, the new fleet is expected to be “among the greenest tugboat fleets in the world” and will provide ship-assist and escort towing services to LNG carriers calling at LNG Canada’s new export facility in Kitimat.
Designed by Vancouver-based naval architects and marine engineers Robert Allan Ltd. (RAL), the tugboats will be built at Sanmar Shipyards. They will use battery-electric power and natural gas instead of diesel fuel.
A new fleet of tugs
As informed, the new fleet of tugs will consist of two RAstar 4000-DF escort dual fuel (LNG and diesel) tugs and three Electra 2800 electric harbor tugs.
At 40 meters in length and with 100 tonnes of bollard pull, they will generate indirect forces of approximately 200 tonnes.
The RAstar 4000 DF escort tugs will perform the majority of their missions using natural gas as their primary fuel. This allows major emissions reductions compared to conventional diesel tugs of the same power, in compliance with the most stringent emissions standards in the international marine industry, IMO Tier III emissions standards.
In addition to these environmental benchmarks, the escort tugs will be capable of pollution response/oil spill recovery, fire fighting of marine terminal fires, person overboard response, and emergency towage of vessels.
