Offshore Platform Services in the Gulf of Thailand
Asset integrity, corrosion control, and HR solutions for fixed and floating offshore platforms in Southeast Asia.
What drives complexity in this sector
Fixed jackets, gravity-base structures and floating production units each present their own corrosion problem: depleting anodes on piles, the splash zone on risers and conductors, produced fluids in the topsides and equipment waiting in storage. JST Group operates across the offshore platforms of the Gulf of Thailand and broader Southeast Asia, providing cathodic protection surveys and retrofits, splash zone coating, corrosion monitoring, integrity surveys and certified offshore crew.
Splash Zone Degradation
The tidal and splash zone presents the most aggressive corrosion environment on any offshore structure — requiring specialist coating systems and regular inspection.
How we solve it: Splash Zone DegradationSubsea CP Performance
Sacrificial anode systems degrade over platform life and must be monitored and supplemented to maintain full protection of subsea structures and risers.
How we solve it: Subsea CP PerformanceOffshore Crew Logistics
Supplying certified offshore personnel — OIM, drillers, deck crews — to platforms in the Gulf of Thailand and beyond requires deep regional networks.
How we solve it: Offshore Crew LogisticsAging Infrastructure
Many Gulf of Thailand platforms are operating beyond their original design life, requiring integrity assessments and life extension engineering.

Offshore Platforms
Where corrosion starts in Offshore Platforms assets, and how we stop it
The asset groups that corrode first, the mechanism behind each, and the JST service that addresses it. Compiled by our Corrosion Control Division from survey and maintenance work across the region.
- 01
Jacket legs and piles
How we solve it: Jacket legs and pilesThe threat Sacrificial anodes deplete over platform life and leave submerged steel below the protection criterion, especially on life-extended assets.
How we protect it CP potential surveys by diver or ROV, Deepwater retrofit anode sleds and clamps, and life-extension design.
- 02
Splash zone, risers and conductors
How we solve it: Splash zone, risers and conductorsThe threat Wet-dry cycling, wave impact and oxygen make the splash zone the fastest-corroding part of the structure, and the risers carry the product.
How we protect it Splash zone coating and wrap systems, riser clamp and support repair, and corrosion-under-clamp inspection.
- 03
Topsides process piping and vessels
How we solve it: Topsides process piping and vesselsThe threat CO2 and H2S in produced fluids, sand erosion at bends and under-deposit corrosion attack separators, headers and flowlines.
How we protect it Corrosion coupons, ER and LPR probes, sand erosion monitoring and inhibitor dosing control from a single data set.
- 04
Flanges, supports and electrical isolation
How we solve it: Flanges, supports and electrical isolationThe threat Crevice corrosion at flange faces, corrosion under pipe supports and galvanic couples between dissimilar metals in a salt-laden atmosphere.
How we protect it GPT flange isolation kits and monolithic joints, Deepwater corrosion-under-support solutions and Artema splash guards on hazardous flanges.
- 05
Subsea pipelines and flowlines
How we solve it: Subsea pipelines and flowlinesThe threat Coating damage from installation and seabed movement, anode depletion and shielding at crossings and riser bases.
How we protect it CIPS over subsea pipelines from a survey boat, retrofit anode systems and CP review for life extension.
- 06
Equipment in storage or lay-up
How we solve it: Equipment in storage or lay-upThe threat Spares, modules and packages corrode in humid marine storage before they are installed, and mothballed equipment seizes.
How we protect it Cortec VpCI vapour-phase preservation for stored equipment, modules and pipeline appurtenances, with Air IQ monitoring of storage conditions.
