Daewoo Shipbuilding & Marine Engineering (DSME) has placed an order with Parker Bestobell Marine to supply cryogenic valves for three new vessels that are part of the Yamal series of Arc7 ice-class LNG carriers. The company had previously supplied cryogenic globe and check valves to the first vessel in the series, which is owned by Sovcomflot.
The valves will be used in the cargo handling systems of the three new LNG carriers, including the main discharge line that controls the initial flow of LNG from the cargo tanks when pumping starts.
The ‘on-deck’ valves will be subjected to extreme sub-zero temperatures. The company will also supply covers for the headworks to protect the exposed parts of the valves.
The LNG carriers will be the first to have electric actuators fitted to globe valves, as it is not possible to use actuators that operate via hydraulic oil due to viscosity issues in arctic conditions.
Parker Bestobell’s Marine’s Market Development Manager, Duncan Gaskin, said: “The fact that our valves have been specified for such a large and prestigious project is testament to the quality of their manufacture. This project called upon the innovation of our design and technical engineers to come up with a solution to ensure that the actuators would operate normally in such extreme environments.”
DSME is yet to build 15 ships in this series for three different owners: MOL (Japan), Teekay (Canada) and Dynagas (Greece).
After 2018, the Yamal LNG project is expected to produce 16.5 million tpy of LNG.
