Sheffield-based Bestobell Marine has won a £1.25m contract with Hudong Zhongua shipyard in Shanghai.
The firm will supply valves for use on four Teekay tankers to be chartered by BG Group.
It takes the total number of Chinese vessels using Bestobell’s valves to 14, helping the company secure its position as a major supplier of cryogenic globe and check valves for liquefied natural gas carriers in China.
Duncan Gaskin, sales director of Bestobell Marine, said: “We are delighted to have secured our third major contract with Hudong Zhongua shipyard.
“Three years ago we had no market share in China and we are now a major supplier for Chinese ships.
“The use of LNG as fuel for ships is rising rapidly in China and we are excited about the opportunities to expand our market here.”
Bestobell’s latest contract is a result of its relationship with its agent in China, Healthlead Development, which has connections with major shipbuilding companies in China.
Tommy Zhang, of Healthlead, said: “Local knowledge counts for more here than in any other market.”
