FPSO Corrosion Control and Offshore Crew Services
Corrosion control, coating, and HR solutions for Floating Production Storage and Offloading (FPSO) vessels.
What drives complexity in this sector
FPSOs present some of the most complex corrosion and workforce challenges in the offshore industry. JST Group delivers hull coating programs, cathodic protection services, satellite connectivity, and certified offshore crew to FPSO operators in the Gulf of Thailand and across the Asia-Pacific region.
Hull Corrosion & Coating
FPSO hulls require continuous monitoring and coating maintenance programs to protect against internal tank corrosion and external marine exposure.
How we solve it: Hull Corrosion & CoatingMooring & Riser Integrity
Mooring systems and flexible risers must be continuously monitored for fatigue, corrosion, and marine growth throughout the vessel's operating life.
How we solve it: Mooring & Riser IntegrityRemote Connectivity
FPSOs operating in remote offshore fields require robust satellite communications for vessel management, crew welfare, and operational data links.
How we solve it: Remote ConnectivityOffshore Crew Deployment
Sustained offshore crew rotations demand certified personnel who understand the specific safety and operational requirements of floating production facilities.

Sector
FPSOs
Where corrosion starts in FPSOs 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
Cargo and ballast tanks
How we solve it: Cargo and ballast tanksThe threat Sea water, cargo acidity and sulphate-reducing bacteria pit tank bottoms and corrode the underdeck, and coating breakdown accelerates it.
How we protect it Sacrificial anode and impressed current CP inside ballast tanks, lining repair programmes and coupons in the water phase.
- 02
Hull exterior and splash zone
How we solve it: Hull exterior and splash zoneThe threat Long station-keeping without dry-docking leaves the hull dependent on CP and coatings for 20 years or more.
How we protect it Hull ICCP monitoring, anode surveys by ROV and splash zone coating repair in service.
- 03
Turret, swivel and risers
How we solve it: Turret, swivel and risersThe threat Crevice corrosion in the turret bearing, riser pull-in areas and chain hawse pipes, where inspection access is limited.
How we protect it Corrosion engineering assessment, targeted CP and coating, and monitoring at the riser and mooring interfaces.
- 04
Topsides process modules
How we solve it: Topsides process modulesThe threat Produced water, CO2, H2S and sand erosion in separators, headers and flowlines under a salt-laden atmosphere.
How we protect it Corrosion and sand erosion probes, inhibitor programmes and coating maintenance on a module-by-module plan.
- 05
Mooring chains and anchor legs
How we solve it: Mooring chains and anchor legsThe threat Chain links lose section to corrosion and wear in the splash and seabed zones, where CP reach is limited.
How we protect it Chain inspection and remaining-life assessment, CP review and link replacement planning.
- 06
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 in a salt-laden atmosphere.
How we protect it GPT flange isolation kits, Deepwater corrosion-under-support solutions and Artema splash guards.
