Tenaris, a supplier of tubes and related services for the world’s energy industry, has been awarded a contract to supply casing and related services for Maersk Oil North Sea UK Limited’s Culzean project.
This ultra high pressure/high temperature 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 will be effective for five years, until 2020, with the option to extend it for two more years.
According to its press release, Tenaris will provide 14” to 7 5/8” casing with TenarisHydril Blue Max, Blue Heavy Wall, and Wedge 523TM 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 high pressure/high temperature applications that demand heavy wall pipe with 100% pressure rated seals. The company says that 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 multi-functional coating applied at Tenaris mills in a fully automatic process that makes thread and running compounds obsolete.
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 Limited and Tenaris recently signed another three-year agreement under which Tenaris will supply products and services for their operations in the Central North Sea.
