Shell asked Tenaris for help with its Olympus TLP in the Gulf of Mexico. Tenaris said in a statement that it will provide the oil company with the TenarisHydril Wedge 623 (TM) Dopeless and Blue Riser connections. The riser was designed to comply with deepwater operating requirement changes in the Gulf and is an improved version of a previous riser.
Tenaris said the Wedge 623 (TM) features an external metal-to-metal seal and an integral connection. The connection for the riser comes with a Dopeless technology, which means it will enhance performance and reliability. Well productivity also increases.
"We are very pleased to accompany Shell in this deepwater project, where reliability is a must," said Julie Mathis, technical sales manager for the United States. "Both new connections are based on field-proven TenarisHydril technologies that enjoy extensive track records. In the case of the Wedge 623 (TM) Dopeless connection, we were able to respond to Shell's technical requirements with a customized product."
A successful test of the riser's casing was completed June 24 and including testing for fatigue performance and sealability after fatigue.
