HOUSTON – Repsol recently deployed Tenaris’ BlueDock connectors with elastomeric seals in the Arima 2 well offshore Trinidad and Tobago. This also marked the first time the connector was used in 30-in. pipes.
“The BlueDock connector showed good performance in running times,” said Alberto Acuña, Tenaris sales coordinator for Central America and the Caribbean. “It was 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.”
A total of 19 joints of 30-in. outside 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 (229 m) and 2,000 ft (610 m), respectively, in the Arima 2 well on the RowanGorilla III platform.
Tenaris field service specialists Fernando Ribeiro, from Brazil, and Wilton López, from Colombia, assisted throughout the operation. “To overcome some well restrictions, the BlueDock connector was subjected to extensive cyclic loads (tension and compression),” Ribeiro said. “After the final successful pressure test, it was possible to prove that the sealability and mechanical performance met the customer’s requirements.”
