Delivered on 24 January 2022 from Wuhu Shipyard, China, Jost Bergmann, Business Director MPV & General Cargo Ships at DNV, notes that “Lady Marie Christine” is one of the first multipurpose dry cargo vessels (MPV) in European short-sea shipping to operate on dual fuel with LNG as the main fuel.
IMO decarbonization goals towards 2050. These are:s Mr. Bergmann explains “Lady Marie Christine” has several state-of-the-art efficiency enhancements which put the ship and its sister vessels on a good track to meet the
- A dual-fuel engine designed to run on LNG as well as conventional marine diesel oil;
- Hull lines optimized to minimize resistance in water in conjunction with a controllable-pitch nozzle propeller;
- Optimized propulsion train and a frequency-controlled, PTO-driven shaft generator allowing the main engine to run at optimum rotational speed and the propeller with optimum pitch;
- Waste heat recovery system.
The combination of all these features allows the ship to achieve an excellent EEDI value of 9.33 g CO2/tNm against the required Phase 2 value of 15.9 g CO2/tNm – in other words, a value as low as 56.7 per cent of the required value
Commenting on the decarbonization features of the vessel, Ad Toonen, Technical Manager at Wijnne Barends, added that the vessel series is designed to meet future environmental legislation without requiring substantial modification.
This can happen as “the interaction between the hull lines and the propeller arrangements is a key factor for the low fuel consumption.”
Engineered cargo flexibility
Furthermore, “Lady Marie Christine” along with its sister ships, “are extremely versatile multipurpose vessels,” stresses Mr. Bergmann, Business Director MPV & General Cargo Ships at DNV.
What is more, as far as efficiency enhancements and emission abatement are concerned, “they go far beyond what is currently standard in the shipping industry.”
