Wärtsilä will supply the engines for Allseas’ latest semi-submersible heavy transport vessel (HTV) under construction at Guangzhou Shipyard International (GSI) in China.
The Wärtsilä 31 engine was selected because of its modular design, which enables a significant reduction in maintenance requirements and costs, and its readiness to use alternative sustainable fuels. “This new HTV strengthens the flexibility of our fleet and how we deliver projects. We selected the Wärtsilä 31 engine for its high efficiency, future-ready design and ability to transition to low and zero-carbon fuels, which supports both operational adaptability and our long-term sustainability ambitions,” said Sytske de Groot, manager, naval architecture – Allseas.
The vessel will operate with four Wärtsilä 31 engines, each fitted with a Wärtsilä NOx Reducer for emissions abatement. Delivery is scheduled for the first quarter of 2028.
HLPFI reported in November that Allseas has contracted (GSI) in China to build the HTV, to be named Grand Tour. It will have a load capacity of 40,000 tonnes, having been designed to carry the world’s largest offshore structures, said Allseas. It has also been designed to fit exactly inside the bow slot of Allseas’ installation and decommissioning vessel Pioneering Spirit to enable the streamlined transfer of offshore structures.
