Shell
awards Canyon Offshore deepwater glider burial contract
Posted: 18 February 2004
Canyon Offshore Inc, a subsidiary of Cal Dive International has
been awarded the Glider Field (GC 248) Flowline Burial Contract
by Shell Exploration and Production Company (SEPCo).
The contract work scope includes the trenching and backfill burial
of the 6.625-inch (~8 inch OD) Glider flowline to enhance the flow
assurance properties of the line. The approximately 32,000-foot
line will be buried in 3000 fsw at the Brutus TLP end, and 3,300
fsw at the G4 well location. This makes the Glider project the deepest
flowline burial project in the world.
The project is scheduled to begin and to be completed in February.
Canyon Offshore will utilize its new T-750 Super-Trencher deployed
from the M/V Northern Canyon to perform the trenching and burial
operations, and a TRITON XLS work class ROV to conduct survey and
post burial survey tasks. In addition, Canyon will also provide
all the pre-engineering, survey, project engineering, project management
and ROV support associated with the work.
Flowline burial is an accepted Shell flow assurance tool. It has
proved effective in previous projects, such as the Angus burial
in 1999, in reducing the amount of flowline insulation required,
or as an alternative to Pipe in Pipe or bundled flowlines.
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.
The company offers a wide range of subsea services to the oil and
gas market, providing ROVSV / construction vessel and ROV services
to support offshore construction, drilling support, survey, engineering,
inspection, backhaul repair and maintenance.
Canyon Offshore also provides flowline and umbilical trenching
services in depths to 2,500 meters to the oil and gas market and
submarine cable burial services to the Submarine Telecom Cable Industry.
