French engineering firm Technip has secured two new subsea contracts from Stone Energy to support the Amethyst field, located on Mississippi Canyon 26 in the Gulf of Mexico.

The first deal requires Technip to provide detailed engineering, procurement, fabrication, assembly and testing of a 5in production static riser and related hardware.

"Technip will manufacture the flexible pipe at its Asiaflex Products plant in Tanjung Langsat, Malaysia, and install it using its Deep Blue deepwater pipelay vessel."

Under terms of the second contract, Technip will install the pipe as a tieback to the Pompano fixed platform, which lies at an approximate water depth of 395m.

The project, which is expected to be completed in the second half of this year, will be managed by Technip’s operating centre in Houston, Texas, US.

Technip will manufacture the flexible pipe at its Asiaflex Products plant in Tanjung Langsat, Malaysia, and install it using its Deep Blue deepwater pipelay vessel.

The Amethyst exploration well encountered around 90ft of net hydrocarbon pay in February 2014.

Technip North America president Deanna Goodwin said: "Technip is proud to bring its experience and to leverage its vertical integration of product design and manufacture and installation vessel fleet to support our customer’s needs."

Technip has industrial assets worldwide, operating a fleet of specialised vessels for pipeline installation and subsea construction.
