The first vessel of our award-winning Environship range has entered service in Norwegian waters and is proving its worth both to customer Eidsvaag AS by cutting operational and life-cycle costs and to the environment through step-change improvements in emissions performance.
Environship is able to generate such radical benefits by combining advanced ship design – incorporating a wave-piercing bow shape that reduces resistance by up to ten per cent – with a series of innovative technologies developed specifically for the maritime industry.
These include new generation of lean burn gas engines from our Bergen range, using liquefied natural gas (LNG), that produce 17 per cent lower levels of greenhouse gases than diesel engines; the Promas integrated propeller/rudder that raises vessel efficiency by up to eight per cent; and our proprietary Hybrid Shaft Generator that delivers electricity at the right voltage and frequency, even at lower engine speeds, to optimise energy usage.
Overall, this installation cuts carbon dioxide (CO2) emissions by 22 per cent, oxides of nitrogen (NOx) by 92 per cent and sulphur oxide (SOx) by 99 per cent over traditional propulsion systems.
Eidsvaag AS is employing its Environship vessel for a regular route, cruising at 15 knots to deliver feed pellets to a network of fish farms off the Norwegian coast. It was designed, and extensively model-tested, to manage the full range of sea conditions the vessel will routinely encounter.
Our dynamic positioning (DP) system and joystick will hold the vessel in position while delivering the feed via a crane-operated transfer system over the bow. The vessel can carry 1,450 tonnes of feed in 60 on-board storage tanks, while the LNG system affords a range of 1,750 nautical miles.
The Environship concept is transferable to many different sectors and vessels types, and there are several further ships at various stages of build, soon to enter service. Cargo vessels from the Environship range will enter service during 2013, while passenger ship and ferry designs are also under development.
