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 ofowner furnished equipment from all different manufacturers (Coflexip,Wellstream, NKT, Cameron, Aker, Oil States, FMC)

Helix, as no other contractor, understands the full costquality developmentof deepwater infrastructure and the importance of reliability as Helix is alsoperforming development of Helixs own oil & gas properties from cradle tograve

The Gulf of Mexico is Helixs home field with dedicated vessels and a spoolbase. We can accommodate ever moving installation windows

Potential for one stop servicewith deepwater construction, diving, trenchingand fabrication of jumpers and PLEMs.

Recent Technical Achievements

20

Canyon Offshore achieved the world record depth for flow line burial onthe Coulomb project for Shell Oil. The 28 mile long Coulomb flow linewas buried in water depths up to 7,576 ft. The burial performed for flow

assurance improvement was a complete success with minimaldowntime 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 forTotal in Vietnam resulting in a worlds first with single pass severance of

conductor and casing strings in under 24 hours each.

Helix Well Ops set world depth record for subsea wirelineintervention from a monohull vessel offshore Australia for Woodsideby retrieving tubing hanger plugs from two subsea wells located in392 m (1,286 ft) of water.

The MSV Express successfully installed a jumper for theIndependence Hub development in the deepest recorded water depth

of 9,083 feet.
