A unique, new type of vessel has been developed, the Ethylene Carrier ECO STAR 36K with “Svelte“-bow design. The design has been developed by Hartmann Reederei of Leer In co-operation with engineering consultants HB Hunte Engineering.
As described by Hartmann, the new vessel type differs fundamentally from conventional gas carriers: As the first of its kind, its superstructures will be located at the bow.
This results in optimized distribution of weight and, therefore, a reduced demand for ballast water − which again leads to reduced fuel consumption and emissions at the same time.
The new “Svelte” bow design enables the vessel to improve seakeeping at higher transit speeds and improved fuel efficiency.
The latest generation of the MAN B&W dual fuel 2-stroke engine on diesel combustion principle will be installed on board of these ships.
This type of engine is characterized by its particularly high reliability and low fuel consumption. Its low emissions meet the requirements of IMO Tier II.
ECO STAR 36K will be able to operate on HFO, MDO and gas oil, as well as LNG, and, as a world novelty, on ethane. Furthermore, it can utilize the boil-off gas from its cargo.
The vessel’s autonomous gas fuel tanks are constructed for ethane and LNG and enable an operating range of about 10,000 nautical miles.
Additionally, the novelty design encompasses heavy fuel tanks for the same distance. If necessary, it is possible to switch over from gas to diesel operation and vice versa immediately.
