The valves, which are due for delivery at the end of this year, will be installed on the five 174K LNG carriers being built by DSME on behalf of Teekay LNG Partners LP of Canada.
In conjunction with DSME, the new valves have been developed over the past two years to meet the exacting standards required for the valves in the new fuel gas systems; this includes withstanding extremely high pressures. The valves are designed to stand a maximum pressure of 370 bar and will be fitted in the gas phase piping of the fuel gas system. Here the LNG is injected into the engine at around 300 bar pressure, with the valve and piping system designed to withstand these pressures.
Bestobell Marine is currently the only manufacturer of high pressure cryogenic globe valves for use in ships’ gas-fuelled engines with the necessary Class Approvals, certification and 3.2 traceability on all components.
Bestobell recently secured its first order to supply its brand new cryogenic high pressure globe valves to DSME
Gas injection engines
Teekay LNG Partners selected new MAN B&W, 2-stroke 5G70ME-GI gas injection engines to power the vessels in an industry first for DSME. The ME-GI engine uses high-pressure gas injection to allow it to provide a more environmentally friendly option to the marine industry, due to less CO2 emissions.
Bestobell Marine is already developing another range of valves that can operate up to a maximum pressure of 500 bar to meet marine industry demands.
”Huge potential for globe valves”
Duncan Gaskin, Sales Director for Bestobell, said: “It is very exciting to be supplying our new high pressure globe valves for the first time for a gas-fuelled engine application. DSME chose to work with us on this high profile project because of our experience and understanding of regulations in the marine industry and in dealing with the Class Societies. There is huge potential for our high pressure globe valves and we are currently in advanced discussions to supply these valves for several other international gas fuel projects.”
