JULY 19, 2017 — Haugesund, Norway, headquartered Knutsen OAS Shipping has ordered four MAN B&W 5G70ME-GI engines with EGR systems in connection with the construction of two 180,000 cu.m LNG tanker newbuildings.
APRIL 7, 2017 — Daewoo Shipbuilding and Marine Engineering (DSME), and classification society DNV GL used this week’s Gastech event in Tokyo to present the results of a joint development project (JDP)
AUGUST 23, 2016 — Qatar’s Nakilat, has entered into a contract that will see Global Eagle Entertainment Inc.’s (NASDAQ: ENT) Emerging Markets Communications (EMC) service provide marine VSAT services for vessels in
The vessel is being built for Saga LNG Shipping Pte. Ltd., a new LNG player backed by Shanghai based Landmark Capital, at China Merchants Heavy Industry’s Haimen based shipyard in China’s Eastern Jiangsu province.
Originally, plans were to build the ship at Xiamen Shipbuilding Industry, but, for undisclosed reasons, the project was delayed and to meet strict deadlines with potential end-users, the project was moved to another shipyard.
Now set to be delivered in early 2018, the vessel will be the to utilize the LNT A-BOX containment system (see earlier story), licensed and designed by another company backed by Landmark Capital, LNG New Technologies (LNT).
Wärtsilä has been contracted to supply the complete cargo handling system including the fuel system, as well as the main propulsion system.
The Wärtsilä cargo handling system for LNG carriers has an integrated fuel system utilizing both compressors and forced vaporizing. The automation and safety control systems are state-of-the-art, while the Wärtsilä cargo pumps include the EFP pump series, the latest development for LNG fuel and spray.
The total solution package comprising the cargo and propulsion systems is designed to attain maximum overall efficiency for the vessel, thereby producing notable savings in operating costs. Furthermore, the total solution concept minimizes interfacing and system design risk during the vessel building process.
“This will be a very modern and highly efficient LNG Carrier and we were selected because our technologies in both the propulsion equipment and cargo handling are world leading,” says Timo Koponen, Vice President, Flow and Gas Solutions, Wärtsilä. “The new ship has been designed for worldwide trade of LNG, but with special consideration given to the reloading of cargoes and local and regional trading. Therefore, the cargo handling system and the fuel efficiency of the engine have to be the most efficient possible. Our unmatched track record with proven LNG technologies and dual-fuel solutions was a key factor in the award of this valuable contract.”
Wärtsilä’s scope of supply includes a comprehensive propulsion package comprising a 12-cylinder Wärtsilä 50DF dual-fuel main engine, 6-cylinder and 8-cylinder Wärtsilä 20DF dual-fuel generating sets, a Wärtsilä controllable pitch propeller (CPP), a Wärtsilä Energopac efficiency rudder, a Wärtsilä gearbox, and a Wärtsilä tunnel thruster.
Delivery of the Wärtsilä equipment to the shipyard will commence in late 2016.
OCTOBER 29, 2015 — Classification society ABS has granted Approval in Principle (AIP) to Troy, MI, based Altair ProductDesign for the Cubic Donut Tank System (CDTS) LNG containment concept. The CDTS concept
The 172,000 cu m LNG ships will be capable of operating in second year ice up to 2.5 m thick.
Yamal LNG has awarded Sovcomflot, MOL, Teekay and Dynagas one, three, six and five vessels respectively. They will be built to dual Bureau Veritas/Russian Register class.
Philippe Donche-Gay, Executive Vice President and head of BV’s Marine and Offshore Division says, “We have made extensive investments in research into ice loads and navigation in ice, working with major Russian institutions and Asian shipyards. This effort, coupled with our world-leading expertise in large LNG carriers gives us a strong technical base to class these highly sophisticated vessels.”
The 300 m vessels each have four GTT NO 96 membrane type LNG cargo tanks.
The tull form is designed with a moderate ice bow forward and a heavy ice-breaking profile aft. The ships are dual-acting, navigating in light ice or open sea bow first, then navigating astern to break heavy ice. The astern ice breaking mode is assisted by the unique podded propulsion system which consists of three pods delivering around 45 MW of power.
Separate engine rooms housing the diesel generator power plants will be encased in a double hull to give protection from the ice and a high level of redundancy.
The ships will be built to Russian Register Arc7 standard, equivalent to an intermediate level between Polar Class 3 and Polar Class 4 of Bureau Veritas rules, for year-round operation in second-year ice with old ice inclusions with ice thickness of 2.5 m.
The vessels will be highly winterized with Bureau Veritas winterization notation COLD (-45,-52) which means that the hull is prepared for operation in -45 Celsius ambient temperature and the equipment should be able to work at -52 Celsius.
Safety of the vessels and care for the environment will be enhanced by a forward and aft ice belt to add strength to the hull in key areas and a very detailed fatigue life analysis to ensure the structure can with withstand the expected extreme stresses for the life of the vessel. Bureau Veritas’ IceSTAR tool is being used to assess the hull ice loads.
Dynagas will build five 172,000 cu. m ARC 7 LNG carriers at the Daewoo Shipbuilding & Marine Engineering Co., Ltd. shipyard in South Korea. They will serve the Yamal project under long term time charters. The vessels will be capable of breaking 2.1 meter thick ice in both the forward and reverse direction.
In addition, four of Dynagas’ existing ARC 4 LNG carriers will come into the Yamal shipping fleet to support Yamal deliveries committed to Asian buyers from year 2019 onwards and will be time chartered for a period of 15 years each.Yamal LNG is a joint venture between NOVATEK (60 percent), TOTAL (20 percent) and China National Oil & Gas Exploration and Development Corporation (CNODC) (20 percent). The project consists of three LNG trains with a total capacity of approximately 16.5 million metric tons of LNG per annum.
“The award of five long term contracts for the ARC 7 LNG carriers and award of four long term contracts for our existing ARC4 LNG carriers is a testament to our long term commitment and our manager’s operational excellence and expertise in operating high specification ice class LNG carriers,” commented Mr. George Procopiou, founder and chairman of Dynagas.
Dynagas Holding Ltd is a holding company engaged in the ownership of LNG carriers and owner of 44% of the equity interests in Dynagas LNG Partners LP (NYSE: DLNG), including the General Partner interest.
