Veka-Group Develops LNG Tankers

Veka-Group has developed  three new LNG tankers, which can also be used as bunker ships.   Two tankers are destined for short sea trips and/or coastal services. The third tanker, a LNG inland waterway bunker ship, is the first of its type in the world.  The tanker sails almost completely on the ‘boil off’ of the load and is 100% emission-free. After the introduction of the first bi-fuel tanker in the world, the “Pioneer Knutsen”, this is again a proof of Veka-Group’s innovative power.    With the “Pioneer Knutsen”, Bijlsma Shipyard, member of the Veka-Group, was years ahead of her time. ‘It was the first bi-fuel LNG tanker ever built’, says managing director Arend Bijlsma. ‘Especially for this project we have developed new technology for the storage of LNG and for the use of LNG as fuel for the propulsion engines. The combination of these two techniques made it possible to sail the tanker for a significant part on the ‘boil off’ (the gas that is released by keeping the load on the correct temperature). The engine switches to diesel in case of insufficient ‘boil off’ availability, which explains the  term bi-fuel.’ Thanks to these innovations applied when building the “Pioneer Knutsen”, the design received the ‘Clean Marine Award ’ from the European Commission.   Use of ‘boil off’ clean and cost-efficient

100 Years With Diesel - Successor Ready

Exactly 100 years ago, the Danish ship Selandia set an example for international shipping as a pioneer within CO2 reduction. Now we are ready for yet another environmental quantum leap. The most distinctive feature of the M/S Selandia was the fact that it had no funnel emitting black smoke up into the sky. The M/S Selandia marked the beginning of the end of steamships. As the first ocean-going ship, she sailed on diesel instead of coal. A technological revolution built at the B&W shipyard

LR LNG Fleet Tops 100

Recent orders of classification services for six liquefied natural gas (LNG) ships have resulted in a milestone for Lloyd’s Register: more than 100 LNG ships now exist or are being built to Lloyd’s Register class, which is significant because the new ships (two for Teekay Shipping and four for BP Shipping at Hyundai Heavy Industries) will feature dual-fuel engines, a recent innovation in LNG ship propulsion. Lloyd’s Register currently classes 37% of the LNG fleet worldwide with a total of

Alternative Fuel: Defrosting LNG

As Cargo, Fuel or both; LNG is emerging as the clear and clean way forward for the maritime industry.   •    In the Beginning     The use of LNG as a marine fuel is not new. Vessels trading cryogenic LNG have burned boil-off natural gas in steam boilers for many years as a simple solution to maintaining necessary temperatures and pressures within cargo spaces. The use of the fuel varied according to the size of the ship and a boil off rate ranging

MAN B&W Diesel to Power LNG Ships

The Shipping Requisition Team has confirmed orders for six Q-max LNG carriers. Each vessel will be powered by two MAN B&W Diesel 7S70ME-C electronically controlled two-stroke low speed diesel engines. These vessels will be the world’s largest LNG carriers, each able to transport 265,000 cu. m. of LNG. The vessel will operate with a reliquefaction plant for operation of boil off gas to the cargo tanks. All 12 MAN B&W Diesel 7S70ME-C engines will be built by

MAN B&W ME-GI Engines Ordered by Teekay

MAN Diesel & Turbo receives another order for the MAN B&W ME-GI dual-fuel, two-stroke, gas-injection engine. Teekay LNG Partners L.P. (Teekay LNG), an offshoot of Teekay Corporation, the international shipping group, has placed an order for two LNG carriers powered by 2 × 2 5G70ME-GI engines, including an option for three further ships. The propulsion solution Teekay has chosen is the most fuel-efficient, low-emission method available on the market.

Greek Shipowners See Advantage of Fuel-Sharing Mode

More LNG Carriers employing 51/60DF engines. MAN Diesel & Turbo has won the contract to supply the engines for two Greek LNG carriers (LNGCs). The installation of the MAN 51/60DF dual-fuel engines aboard the newbuildings represents an important first such reference for the company in the segment. The configuration for the new order covers 2 × 9L51/60DF + 2 × 8L51/60DF engines, a total of 34 MW installed power per vessel

MAN B&W Gas New Liquid ME-GI Engine

MAN Diesel & Turbo introduced its Liquid ME-GI (Liquid Gas Injection) engine. The Liquid ME-GI is powered by LPG (Liquid Petroleum Gas), a smaller market than LNG but of significance in certain segments such as the small tankers that ply river traffic and coastal shipping routes. The Liquid ME-GI is a variant of MAN Diesel & Turbo‘s ME-GI engine, whose control and safety system is based on the experience gathered since the mid-1990s at working gas plants

OSG Names Largest LNG

Overseas Shipholding Group, Inc. has named the LNG Carrier Al Gattara, marking a new generation of Q-Flex Liquefied Natural Gas (LNG) carriers, said to be the world’s safest, most advanced and largest ships to transport this critical energy source. This vessel is the first in a series of four sister ships to be delivered to OSG Nakilat, the joint venture between OSG and Qatargas Transport Company (Nakilat). The ship’s sponsor, Mrs

LNG Tech on tap at Europort 2013

Emissions regulations from 2015 onwards are driving shipowners to a crossroads on fuel selection. Ahead of Europort 2013, Rotterdam, Dutch interests are making significant waves in tangible investments in LNG as a fuel option. While there is not consensus on the potential of liquefied natural gas (LNG) as a marine fuel, the concept is gaining traction rapidly as using LNG reduces nitrogen oxide (NOx) and carbon dioxide (CO2) emissions from ships
