Offshore completes Glider burial
Posted: 8 April 2004
Canyon Offshore, Inc. has completed the burial of the Glider Field
(GC 248) Flowline for Shell Exploration and Production Company (SEPCo).
The contract work scope included the trenching and backfill burial
of the newly laid 6.625-inch (~8 inch OD) Glider flowline to enhance
the flow assurance properties of the line.
The approximately 32,000-foot line was buried in 3000 fsw at the
Brutus TLP end, and 3,300 fsw at the G4 well location to an average
depth of approximately 6 ft. This makes the Glider project the deepest
flowline burial project in the world.
The project began on February 9, 2004 and was completed on March
15th on a single mobilization. Canyon Offshore utilized its new
T-750 Super-Trencher deployed from the DP II M/V Northern Canyon
to perform the trenching and burial operations.
A TRITON XLS work class ROV was provided to conduct survey and
post burial survey tasks. In addition, Canyon provided all the pre-
engineering, survey, project engineering, project management and
ROV support associated with the work.
Canyon Offshore, Inc., a member of the Cal Dive group of companies,
is headquartered in Houston, and maintains operational offices in
Aberdeen and Singapore, and a base in Vietnam.
