Helix Subsea Construction Differentiators

13

Helix has extensive experience in (ultra) deepwater construction(pipelines, PIP and insulated flowlines, umbilicals, manifolds, trees, jumpers, flying leads up to 9,000 fsw) and in installation and operation of owner furnished equipment from all different manufacturers (Coflexip, Wellstream, NKT, Cameron, Aker, Oil States, FMC)

Helix, as no other contractor, understands the full cost quality development of deepwater infrastructure and the importance of reliability as Helix is also performing development of Helix’s own oil & gas properties from cradle to grave

The Gulf of Mexico is Helix’s home field with dedicated vessels and a spool base. We can accommodate ever moving installation windows

Potential for one stop service with deepwater construction, diving, trenching and fabrication of jumpers and PLEM’s.

Recent Technical Achievements

20

Canyon Offshore achieved the world record depth for flow line burial on

the Coulomb project for Shell Oil. The 28 mile long Coulomb flow line

was buried in water depths up to 7,576 ft. The burial performed for flow

assurance improvement was a complete success with minimal

downtime and high profitability.

The Q4000 removed a hydrate plug in a Mariner deepwaterflowline in the Gulf of Mexico using five miles of drill pipe.

Helix Well Ops successfully abandoned 5 subsea wellheads wells for Total in Vietnam resulting in a world’s first with single pass severance of

conductor and casing strings in under 24 hours each.

Helix Well Ops set world depth record for subsea wireline intervention from a monohull vessel offshore Australia for Woodside by retrieving tubing hanger plugs from two subsea wells located in 392 m (1,286 ft) of water.

The MSV Express successfully installed a jumper for the Independence Hub development in the deepest recorded water depth of 9,083 feet.
