Repsol runs BlueDock connectors in Trinidad and Tobago

Posted on 18 August 2014

Repsol recently ran Tenaris‘ BlueDock connectors with elastomeric seals in Trinidad and Tobago. The operation took place in the Arima 2 well from the Rowan Gorilla III jackup in a water depth of 283 ft. This marked the first time that the connector was used in 30-in. pipes. “The BlueDock connector showed good performance in running times, an effective installation of the anti-rotation device and demonstrated to be an overall solution for the customer’s requirements: mechanical resistance, sealability and connector stability,” said Alberto Acuña, Sales Coordinator for Central America & Caribbean for Tenaris.

A total of 19 joints of 30-in. outer diameter (OD) x 1.000-in. Wt API 5L X56 conductor casing and 41 joints of 20-in. OD x 0.625-in, Wt grade API 5L X56 surface casing were installed with zero rejects at a total length of 750 ft and 2,000 ft, respectively.

“To overcome some well restrictions, the BlueDock connector was subjected to extensive cyclic loads (tension and compression). After the final successful pressure test, it was possible to prove the sealability and mechanical performance met the customer’s requirements,” Tenaris Field Service Specialist Fernando Ribeiro said.

BlueDock connectors, manufactured at Tenaris’ welded pipe mill in Brazil, draw on TenarisHydril’s expertise in proprietary connection design and experience in welding and pipe manufacturing.

The weld-on connectors ensure easy stabbing and trouble-free makeup for fast and reliable running along with 100% ratings in tension, compression and bending. They have also undergone sealability tests based on ISO 13679 standards, as well as full-scale make and break tests.

BlueDock is a trademark of Tenaris.
