Vallourec has delivered 14 000 t of premium tubes in the scope of a contract with Hess Corp. for the Stampede project in the US Gulf of Mexico. Stampede is a deepwater subsea development, which is located in the Green Canyon Block area, approximately 115 miles south of Fourchon, Louisiana.
Vallourec is providing over 5000 t in various sizes of oil country tubular goods (OCTG) for the critical deepwater development wells, including high performance premium grades from Europe and Ohio. Over the life of project the majority of the pipes will be threaded at VAM USA, Houston, TX, with VAM®SLIJII™ and VAM® HP™ for a total of over 12 000 premium connections.
Vallourec's contract also covers 9000 t of seamless steel line pipe for flowlines and steel catenary riser (SCR). They will be installed in water depth of approximately 3500 ft (over 1000 m). Amongst the scope of products and services, Vallourec will provide SCR pipes with very tight pipe end tolerances and optimal welding characteristics, key features to reduce both the cost and risk of project execution.
