Tenaris has been awarded a five-year contract to supply casing and related services for Maersk Oil North Sea UK's Culzean project.
This ultra high-pressure, high-temperature (HPHT) gas project is located in the United Kingdom’s North Sea continental shelf and accounts for six HPHT production wells together with one PWRI well. The agreement comes with the option to extend it for two more years.
Tenaris will provide 14in to 7 5/8in casing with TenarisBlue Max and Blue Heavy Wall, and TenarisHydril Wedge 523 connections, all with Dopeless technology, along with sour service and high collapse grades. The contract also covers the provision of services such as prequalification and testing of products.
The TenarisHydril Blue Max and Blue Heavy Wall connections, which come with Dopeless technology, were designed for HPHT applications that demand heavy wall pipe with 100% pressure rated seals. Blue Heavy Wall combines the highest levels of performance in compression, external pressure, and slim geometry with the benefits of the Dopeless coating. They both continue to be tested under the forthcoming revision of the API RP 5C5 CAL IV protocol.
Dopeless technology is a dry multifunctional coating applied at Tenaris mills in a fully automatic process that makes thread and running compounds obsolete. Tenaris’s dope-free solution ensures reduced running times, improved reliability of the running, offshore savings of the total pipe cost and environmental benefits. The contract also covers the provision of services such as prequalification and testing of products, stock management, preparation for offshore and inspection of material, as well as field services.
Maersk Oil North Sea UK and Tenaris recently signed another three-year agreement under which Tenaris will supply products and services for their operations in the Central North Sea.
