Rolls-Royce Plc has delivered the first of a revolutionary new design of cargo ship which will reduce CO2 emissions by up to 40 per cent, thanks to a combination of cutting edge marine technology, including a wave-piercing bow and an engine powered by natural gas, whereby the gas is stored as liquefied natural gas (LNG).
The first Rolls-Royce Environship, of NVC 401 LNG design, the Eidsvaag Pioner, has been delivered to Norwegian company Eidsvaag AS this week, and will soon enter service on a year-round schedule delivering feed to numerous fish farms around the Norwegian coast.
The Environship, which can be adapted for different ship types, incorporates a range of Rolls-Royce technologies to deliver efficiency savings for ship owners. When compared to similar sized diesel powered ships, the CO2 reduction can be up to 40 per cent.
Neil Gilliver, Rolls-Royce, President - Merchant, said: "The Environship has now moved from concept to reality with the successful delivery of the first ship... [More]
DNV (Det Norske Veritas) classification society now offers shipowners the support they need to make newbuilds and existing vessels ‘LNG ready’ with class approved designs, ready for later, simple retrofit of LNG technology. The service enables shipowners to make smart choices and minimal investments now in readiness for when LNG bunkering becomes widely available.
Shipowners are supported through all stages of the decision-making process as they prepare to meet the IMO air emission regulations entering into force from 2015. There are three obvious technology options for meeting Emission Control Area (ECA) requirements: installing a scrubber, switching to low sulphur fuel oil or to go for LNG as fuel and installing gas engines. Alternative fuels such as methanol and biofuels are also being developed.
“Each option has different uncertainties, for example the relative immaturity of some technologies and the effect market forces will have on the price of the d... [More]
News in the past week boosted diesel engine manufacturer Wärtsilä's business in the offshore platform supply vessel sector: First a major contract to design and power a series of four multi-purpose platform support vessels (MPSVs) for Malaysian-based international offshore oilfield services provider Bumi Armada Berhad. Then, from the other side of the world, came word that the United States Environmental Protection Agency (EPA) had certified the company’s 34DF engine (soon to be installed in a new series of Gulf of Mexico US-flag platform support vessels) as emission standard compliant.Malaysia MPSV OrderWärtsilä will supply a comprehensive design and propulsion package for each of the four vessels to be built by a subsidiary of Nam Cheong Limited, in one of its subcontracted yards, Fujian Mawei Shipbuilding Ltd, in China.

The deep water of Lake Kivu on the Congolese-Ruanda border contains large quantities of methane and carbon dioxide. The reserves of methane are estimated to be 65 km3 (65 billion cubic metres) and carbon dioxide reserve 255 km3. The methane is considered to be partly magmatic in origin, produced by microbial reduction of the volcanic carbon dioxide, and partly biogenic through the anaerobic reduction of dead algae and fish on the lake floor.
In the past the lake has erupted at irregular intervals, belching out these deadly gases. In 1986 a similar eruption at Lake Nyos in Cameroon killed 1.800 people – including some living as far as 25 km from the lake. With two million people living in the basin of the much larger Lake Kivu, this represents a mega-disaster waiting to happen.
But the methane gas also provides an accessible and renewable energy resource to the Kivu region, valued at tens of billions of dollars.
In collaboration with the US energy company Contour Glo... [More]

Yesterday, the world’s first fuelling vessel for LNG (liquefied natural gas) was christened in a traditional christening ceremony in Stockholm, by Helena Bonnier, the chairman of Ports of Stockholm (Stockholms Hamnar), in the presence of the Minister of Infrastructure, Catharina Elmsäter-Svärd, among others.
In spring of 2012, the Swedish government decided to support what was then a TEN-T request about a LNG fuelling vessel. One year later, the ship is christened and constitutes as an additional component in a competitive maritime shipping with quality, safety and a strong environmental profile, says the Swedish Minister of Infrastructure, Catharina Elmsäter-Svärd.
The LNG fuelling vessel, Seagas, is the first ship in the world of its kind, and is classified under the same regulations that apply to oceangoing LNG-tankers. The fuelling vessel will on a daily basis, supply 60-70 tons of LNG to M/S Viking Grace, the new cruise-ship of Viking Line, when the ship ... [More]
The Norwegian shipping industry is teaming up and has taken a leading role in developing battery-powered ships. The first four hybrid vessels will start to sail in 2013/14. In 2015, they will be followed by the world largest fully electric ferry, which will regularly cross Norway’s largest fjord.
Some 120 managers representing the entire maritime cluster were gathered at a DNV seminar last week. “15 years ago, the Norwegian cluster was looking into opportunities for gas-fuelled ships. Today, Norway is the pioneer when it comes to LNG-fuelled ships. Electricity stored in batteries on board ships is another opportunity in the future energy mix and another technology race which has started. We have been running that track for a while already,” says Narve Mjøs, Director of Battery Projects in DNV and in charge of the seminar.
“International shipping is facing a tough time with escalating fuel prices, stricter environmental regulations and very low day rates ... [More]
“WSF burns more than 17 million gallons of ultra-low sulfur diesel each year – and it’s our fastest growing operating expense. LNG has the potential to significantly reduce emissions and the cost of fuel,” said Washington State Department of Transportation (WSDOT) Assistant Secretary David Moseley.
LNG as a fuel is a promising, but new technology for WSF. To ensure that the safety, security and operational challenges of such a move is handled in a responsible manner, Washington State Ferries has partnered with DNV, a risk management company with extensive experience of LNG fuelled ships and the infrastructure they demand.
MV KALEETAN might be operated with LNG in the future
DNV has taken the leading role in making LNG as a fuel safe and viable. 35 out of 37 LNG fueled vessels in the world, including the very first in 2000, have been built to DNV’s standards. Of these, 16 are car/passenge... [More]
