Tank Farm Corrosion Protection and Coating Services
Corrosion protection systems for aboveground storage tanks, tank bottoms, and associated infrastructure.
What drives complexity in this sector
A tank farm is more than its tanks: intermediate piping, fire-water ring mains, foam lines, bunds and marine loading lines all need protection and maintenance alongside the tank floors. JST Group delivers cathodic protection design and installation for tank bottoms and buried pipework, CorroLogic under-floor protection, coating inspection and rehabilitation, and corrosion monitoring programmes for tank farm operators across the region.
Tank Bottom Corrosion
Internal corrosion of tank floors is one of the leading causes of leaks and environmental incidents at storage facilities.
How we solve it: Tank Bottom CorrosionExternal Coating Degradation
Atmospheric corrosion on shell and roof surfaces requires regular inspection and recoating programs.
How we solve it: External Coating DegradationSoil-Side CP Design
Impressed current and sacrificial anode systems must be carefully designed for mixed soil resistivity and tank farm geometries.
How we solve it: Soil-Side CP DesignInspection Access
In-service and out-of-service tank inspection requires specialised methods to assess condition without disrupting operations.
How we solve it: Inspection Access

Tank Farms
Where corrosion starts in Tank Farms 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
Tank floors, soil side
How we solve it: Tank floors, soil sideThe threat Moisture in the sand bed, chloride contamination and uneven cathodic protection corrode the underside of the floor where no inspection can see it.
How we protect it Impressed current or galvanic CP under the floor, CorroLogic vapour-phase inhibitor injected into the sand bed, and annual potential surveys.
- 02
Tank floors and lower shell, product side
How we solve it: Tank floors and lower shell, product sideThe threat Water bottoms, sludge and microbiologically influenced corrosion pit the floor plates and first shell course from the inside.
How we protect it Internal linings, water draw-off routines, corrosion coupons and ER probes in the water phase, and floor scanning when the tank is out of service.
- 03
Shell, roof and structure
How we solve it: Shell, roof and structureThe threat Atmospheric corrosion, coating breakdown at welds and edges, and crevice attack under roof seals and stair brackets.
How we protect it Coating condition surveys, surface preparation and recoating, scheduled around product cycles.
- 04
Intermediate and transfer piping
How we solve it: Intermediate and transfer pipingThe threat Buried sections lose coating, pick up interference from nearby CP systems and corrode at road crossings and soil-to-air interfaces.
How we protect it DCVG and CIPS surveys, CP extension, isolation joints at the tank boundary and petrolatum or heat-shrink protection at transitions.
- 05
Fire-water ring main and foam lines
How we solve it: Fire-water ring main and foam linesThe threat Stagnant water, internal tuberculation and soil-side corrosion of buried mains that are pressure-tested but never inspected.
How we protect it Cathodic protection of the buried main, internal corrosion monitoring at test points and a leak survey of the ring.
- 06
Pipe supports, flanges and bund penetrations
How we solve it: Pipe supports, flanges and bund penetrationsThe threat Corrosion under supports, crevice corrosion at flange faces and spray from flange leaks onto walkways and bund floors.
How we protect it Deepwater corrosion-under-support solutions, GPT flange isolation kits and Artema splash guards on hazardous flanges.
What we deliver in this sector
Each service links directly to the relevant page for full capability detail.
Cathodic Protection
Impressed current and sacrificial anode CP for tank bottoms and buried pipework.
Coating Services
Coating inspection, surface preparation and recoating for tank shells, roofs and pipework.
Corrosion Monitoring
Monitoring that confirms CP performance and tracks corrosion across the tank farm.
Chemical Solutions
Tank-bottom corrosion protection and preservation chemistry for storage assets.
NDE Inspection
NDT and corrosion mapping to assess tank and pipework condition.
Survey & Inspections
Drone, structural and integrity inspection of tanks and site infrastructure.
Pipeline Coating & CP Surveys: DCVG, ACVG, PCM, CIPS
Above-ground surveys that identify, locate and grade coating defect indications and assess cathodic protection performance along the route, with a prioritised repair list. The indirect-inspection step of an ECDA programme (NACE SP0502), and equally suited to buried plant and tank-farm pipework (not tank bottoms).
