Newbuilds for Canada’s Desgagnés by Besiktas in Turkey
Parker Bestobell Marine is supplying cryogenic fuel gas valves for two tanker newbuilds for Groupe Desgagnés of Canada, the Parker Hannifin unit reports. The liquefied natural gas-fuel oil, dual fuel-powered ships are being built by the Besiktas Shipyard in Turkey, Bestobell says, noting that they are 15,000-dwt (deadweight-tonnage) ice-class 1A asphalt and bitumen tankers.
The ships will have 600-cubic-meter (158,000-gallon) LNG fuel tanks, Bestobell says, and are to operate on the Great Lakes and Canada’s St. Lawrence River.
Because of the low winter temperatures in Canada, the valves and actuators have been specified to operate in temperatures as low as minus-40 centrigrade, the company says: “This is not an issue for Parker Bestobell’s cryogenic valves,” the company adds. Its valves are designed to operate to temperatures as low as minus-196. The actuators for the new Desgagnés ships were modified to operate to minus-40.
Elsewhere for the coldest climes, Bestobell is to supply its cryogenic globe and check valves for the cargo handling system on the Yamal series of LNG carriers being built at the DSME/ Daewoo Shipbuilding & Marine Engineering shipyard in South Korea. The valves for the Yamal carriers “will be required to withstand winter temperatures as low as minus-54 centigrade, as well as excessive build-up of ice.”
Bestobell says its valves have been used in more than 30 LNG fuel gas projects, with cryogenic globe and check valves for the Energy series of ships by Harvey Gulf International Marine being “the most high profile,” as the first LNG-fueled vessels to be built in America. The first, Harvey Energy entered service early last year (HHP Insight, March 5, 2015).
Low and High Pressure Products
Parker Bestobell Marine provides full fire-safe valves based on a proven design that has been used for more than a decade for LNG shipping applications. In low pressure systems the valves are fitted in the tank room space between the LNG fuel tank and the engine “and are a critical part of the piping system that feeds the LNG fuel to the vaporizers, which convert it back to a gas.”
More recently, the company developed a new range of high-pressure globe valves that are fitted in fuel gas systems for MAN Diesel & Turbo ME-GI engines where natural gas is injected into the engine at more 300 bars of pressure – 4,350-psi/pounds per square inch. “MAN has sold over 100 of this type of engine and this is driving a rapid increase in demand for Parker Bestobell Marine’s high pressure cryogenic valves for these fuel gas systems,” the manufacturer says.Contact information is only available to premium subscribers.
