Wärtsilä will collaborate with ABS and Hudong-Zhonghua Shipbuilding (HZS) to develop a LNG carrier (LNGC) vessel concept
The design approach for the multi-fuel electric vessel is intended to deliver immediate CO2 savings, and to be ready for the adoption of future decarbonisation technologies to support the marine industry’s turn towards zero-emissions shipping.
Wärtsilä said its integrated systems and solutions experts are working alongside specialists from ABS Global Simulation Centre and Global Sustainability Centre in Singapore, Houston and Athens and HZS’ R&D and LNGC design team in Shanghai to evaluate the vessel’s performance against the IMO’s carbon intensity indicator (CII) up to at least 2050.
This involves using advanced multi-physics modelling and simulation, and applying decarbonisation technologies and solutions to the vessel’s design and operational modes.
The LNGC will be highly flexible with the vessel design optimised around a compact, electrified, integrated, propulsion system to significantly reduce CO2 emissions.
A hybrid system will be developed to power the vessel, enabling dual-fuel engines to run at optimal efficiency and providing flexible power supply modes to adapt to various load demands. And the vessel’s design will be future-proofed so it can efficiently integrate new technologies in the future to stay ahead of the requirements of CII.
“The evolving demands of the CII mean vessels will need to be ready to continuously adapt to improve their rating and remain viable for the duration of their operational life.
Advanced multi-physics modelling and simulation techniques enable the development of a vessel with a strong CII profile at launch that is also equipped to take advantage of future decarbonisation technologies as they mature,” said ABS senior vice president global engineering and technology, Patrick Ryan.
HZS deputy director of R&D Song Wei said, “We are very glad to work with Wärtsilä and ABS to develop the new generation of LNG carriers offering a low-carbon footprint and low opex cost.”
Wärtsilä Marine Power vice president power supply Stefan Nysjö said, “The modular and hybrid smart propulsion system also provides the correct foundation for the introduction of new and potentially highly intermittent low-carbon energy sources and propulsion energy saving devices, both in the newbuild phase and also later as potential retrofit solutions.”
