Ezra subsidiary Emas AMC has completed the first two of three subsea tieback projects operated by Noble Energy in the US Gulf of Mexico.

Emas has performed services that include project management, fabrication and installation of 8in steel catenary risers. In addition, it has provided 40 miles of 8in and 12in pipe-in-pipe (PIP) for the Big Bend and Dantzler field development projects in water depths of 7,000ft.

The project also included the design, fabrication and installation of eight 100t subsea structures.

"Lewek Constellation has conducted more than 30 heavy-lifts of between 900t and 2,200t, transferring rigid pipe reels since May."

Emas carried out project management activities at its Houston office, while the pipeline production and structures were fabricated at the EMAS Marine Base (EMB) in Ingleside, Texas, US.

For the Big Bend and Dantzler projects, Lewek Constellation has conducted more than 30 heavy-lifts of between 900t and 2,200t, transferring rigid pipe reels since May.

Ezra Group CEO and managing director Lionel Lee said: "We are proud to announce a record for what we understand is the heaviest pipe-in-pipe (PIP) system ever deployed in the world using the reeling methodology, whilst proving the viability of our offshore reel-transfer technology in open waters.

"Our game-changing vessel used in combination with our unique transportable reel delivery system will offer clients more efficient pipe-lay options in ultra-deepwater when compared to more traditional methods."

Emas recently finalised a contract with BHP Billiton for the Angostura phase 3 development offshore Trinidad and Tobago in the eastern Trinidadian sector of the Venezuela basin.
