Specialist ship owner Anthony Veder, Netherlands, new LNG carrier ordered from Mayer Werft, Germany for construction at the Neptun Yard in Rostock is due for delivery in the second quarter of 2012. A direct mechanical drive system is specified for the vessel which is believed to be the first application of its type: previous LNG carriers use a dual fuel diesel electric arrangement. The Anthony Veder Group presently has a fleet of 21 gas tankers with a further four ships on order.

kind to use a direct mechanical drive with a dual fuel engine.

The new LNG carrier has a capacity of 550,000 ft3 (15,600 m3) with a LOA of 512 ft (156 m) and beam of 74 ft (22.7 m) and is designed for the distribution of LNG rather than long distance transporting from the major gas fields. Its main area of operation will be in the North Sea and Baltic Sea Emission Control Areas (ECA).

The single shaft propulsion system comprises a Wärtsilä 50DF dual-fuel engine going through a reduction gearbox to a controllable pitch propeller. Two Wärtsilä 20DF dual-fuel auxiliary engines provide electrical power. Wärtsilä dual fuel engines operate on LNG as the main fuel with pilot diesel fuel injection to initiate combustion. If required the engines can operate on diesel fuel only.

Operation on LNG all but eliminates SOx emissions and reduces the production of CO2 and NOx to levels that are sufficiently low as to be within the IMO Tier 3 NOx regulations and compliant with the requirements of the ECAs.

Great caribbean will be also Special Area for Marpol Ann VI, therefore LNG should be an interesting option for reduction of emission by ships
