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...

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]

First two stroke gas engines for LNG carrier

Teekay LNG Partners L.P. Head Office, Bermuda, has ordered two 173,400m3 LNG carriers from Daewoo Shipbuilding & Marine Engineering in Korea. The vessels will each have two MAN Diesel & Turbo ME-GI dual-fuel, ultra long two-stroke gas injection engines. These engines received DNV type approval in 2010 and their use as part of an innovative propulsion package is claimed to give significant fuel savings when compared to propulsion commonly used for LNG carriers today.  DNV experience from risk assessments of LNG-fuelled ships shows that a gas-fuelled main engine has the same risk level as a diesel-fuelled main engine. One reason for the low risk is that the main engine undergoes rigorous type approval and testing regimes as well as being subject to stringent rule and regulatory requirements. The new electronically controlled, two-stroke ME-GI engines from MAN Diesel & Turbo have undergone extensive testing. The engines will automatically switch between burning LNG and fu... [More]

Chevron Corporation orders G-type units with integrated exhaust gas recirculation G-type engines with integrated EGR system offer both high efficiency and low NOX emissions. MAN Diesel & Turbo has received an order from Chevron Corporation, the American multinational energy company, for two lightering newbuildings with each vessel to be powered by an MAN B&W 6G70ME-C9.2 prime mover. The newbuildings will each use an MAN Diesel & Turbo EGR (Exhaust Gas Recirculation) system to help their ME-C prime movers meet Tier III emission standards well in advance of requirements coming into effect. The engines will also retain the ability to switch to Tier II operation when outside the ECA (Environmental Control Area). MAN Diesel & Turbo states that the engine for the first vessel has a delivery date in December 2012, with the second due in early 2014 and the vessels due for delivery in 2014. Chevron has also ordered 1 × MAN 8L27/38 + 2 × MAN 7L21/31 gensets for each v... [More]

Norway is Forerunner in Innovative Ships Propulsion Technologies

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 ...

“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]

Siemens, Norwegian shipyard Fjellstrand and shipping company Norled have developed what they say is the world’s first electrically powered car ferry. The 80-meter vessel can carry 120 cars and 360 passengers. From 2015 onward, it will serve the route between Lavik and Oppedal, Norway, across the Sognefjord. The vessel currently serving this route uses on average one million liters of diesel and emits 570 metric tons of carbon dioxide and 15 metric tons of nitrogen oxides a year. The companies developed the electrically powered ferry for submission to a competition organized by Norway’s Ministry of Transport.  As a reward for winning the competition, the shipping company Norled has been granted the license to operate the route until 2025. Rather than a diesel engine, the ferry is equipped with electric motors to drive the ship’s two screws. These motors are powered by a battery weighing 10 metric tons. The ship has been specially designed to fit the requirements ... [More]

International Ship Insurance Companies advise alertness at heavy fuel oil bunkering

Filed Under: drive systems, Fuels & Lubes, General
Fuel impurities are an ongoing problem in ship operations. In spite of quality and delivery standards again and again poor heavy fuel oil is offered worldwide in many ports. This leads to severe engine damages and extremely high costs for the shipping owner. But what are the main impurities? And what can the ships crew do to be warned?    In the case of impurities these are mainly cat fines, asphaltenes, water and dirt. Asphaltenes, water and dirt can be removed by the use of good separation devices, like separators. What are cat fines and can they be separated?  In order to make petrol or other fuels out of crude oil, refineries work with the catalyst cracking process. So-called “cat fines” (including aluminum and silicon compounds) are used as catalysts and these are then found in the fuel. Cat fines are extremely damaging to engines. Cat fines are substances like silicon and aluminum compounds which are required as catalysts in the refining process known ... [More]
