STATS reinstates anchor-damaged gas pipeline offshore Thailand

STATS reinstates anchor-damaged gas pipeline offshore Thailand

STATS Group has completed a subsea pipeline repair and isolation project in
the Gulf of Thailand.

CUEL commissioned the company to address damage to the 8-in. gas condensate
export pipeline which had been dragged 8 m (26 ft) out of position by a
vessel anchor and needed a permanent repair.

For this program STATS deployed products that included slab valves, hot tap
fittings, completion plugs, end connectors, and abandonment plugs.
This allowed the repair to be effected without impacting production or diver
safety.

An 8-in. bypass was installed on the seabed as a permanent repair to
re-route the pipeline medium away from the damaged pipeline section, which
was in around 60 m (197 ft) of water and which had an operating pressure
ranging from 7-21 bar (101-304 psi).

STATS' applied its BISEP system to provide leak-tight isolation of the
pressurized pipeline, deployed through a full bore hot tap penetration at
the isolation location via a mechanical hot tap fitting.

The company's previous subsea isolation, for COOEC Subsea Technology,
involved repairing the Yacheng pipeline in the South China Sea following
damage by a ship's anchor.

It repaired the line at an unpiggable location 280 km (174 mi) from shore
and in water depths of 60 m without depressurizing and flooding the entire
pipeline.
