In a contract worth $110 million, Trinity to build two dual fuel LNG-powered PSV’s for Harvey Gulf. Wartsila to supply integrated system that includes the dual-fuel machinery.

 

7 October 2011: Harvey Gulf International Marine has signed a deal with Trinity Offshore which will eventually produce the first two dual fuel LNG-powered offshore  vessels under U.S. flag. The deal, reportedly worth at least $110 million, calls for the delivery of the first vessel in November 2013 with the second hull to follow about 4 months later. The vessels will be built in Trinity’s Gulfport location. Initially, Signal International was  the frontrunner for the contract, but ultimately, Harvey Gulf chose Trinity.

 

Chad Verret, Vice President of Deepwater Operations for Harvey Gulf International Marine told Marinelink this morning that the vessels would be powered by Wärtsilä, who has been awarded a contract to supply liquefied natural gas (LNGLF) (LNG) propulsion equipment for the two advanced offshore supply vessels. The contract includes options for supplying propulsion equipment for additional follow-on vessels. Verret expects building of the first vessel to commence immediately.
 
 

Wärtsilä will deliver an integrated system that includes the dual-fuel machinery, electrical and automation package, complete propulsion, and also the LNG fuel storage and handling components. The STX Marine Inc SV310DF Offshore Support Vessels will be powered by Wärtsilä 6-cylinder 34DF dual-fuel engines. The LNG storage capacity of 290 cubic meters (m3), enables more than a week of vessel operational time. In addition, the vessels will carry 5520 tons of deadweight at load line and have a transit speed of 13 knots. The vessels are scheduled for delivery in two years and will operate in the Gulf of Mexico.
 
 

Shane Guidry, Harvey Gulf International Marine’s Chairman and CEO, said in a prepared statement,  “We’re committed to bringing the world’s best technologies to our customers, and these vessels with Wärtsilä’s integrated system based on the use of LNG further demonstrates Harvey Gulf’s Going Green Vision.”
