LONDON, July 9 -- TotalFinaElf SA's Canyon Express pipeline project in the US Gulf of Mexico has moved ahead with the completion of the flowlines pre-lay survey, subsea contractor Sonsub Inc. said Monday.

Using the HOS Innovator vessel and Innovator 9 ROV spread, Sonsub conducted a bathymetric survey of the proposed pipeline routes, grid surveys of the proposed sled lay down areas between the Canyon Station platform at Main Pass 261 to a termination point in Mississippi Canyon Block 348, as well as recording ROV survey fixes of existing wellhead locations.

Sonsub, the subsea specialist division of Italian contractor Saipem SPA, has a contract for Canyon Express that includes design of subsea intervention equipment and offshore installation of pipeline jumpers.

The company's next task will be the installation of pipeline crossings at four locations.
