Offshore platform deck stripping, hydrocarbon extraction, and tanks.
Oil & Gas Refining, Marine Terminals & Offshore Platforms
Offshore platform deck stripping, hydrocarbon extraction, mud tanks, and coastal refinery piping.
Upstream exploration rigs, midstream marine offloading terminals, and coastal petrochemical refineries require aggressive industrial decontamination under extreme safety scrutiny.
Chow Marine specializes in Class 1, Division 1 explosion-proof cleaning protocols. Our equipment suites feature pneumatic, hydraulic, and intrinsically safe electric drives that eliminate ignition sources while stripping heavy asphalthenes, paraffin waxes, and pyrophoric iron sulfide scales.
On offshore semi-submersibles and drillships, our crews tackle mud pits, ballast tanks, drilling risers, and splash-zone structural jackets subjected to marine growth and crude buildup. Our multi-stage heated water jetting units (up to 95°C at 40,000 PSI) melt and wash away heavy crude residues, allowing ultrasonic thickness testing and NDT inspections to proceed without delay.
At coastal terminals, we clean marine loading arms, bunker fuel storage tanks, and subsea bunkering manifolds, coordinating closely with port authorities and environmental regulators to ensure zero hydrocarbon discharge into harbor waters.
Vapor Gas-Freeing & LEL Testing
Nitrogen purging, continuous multi-gas monitoring for VOCs, H₂S, and LEL, with certified gas-free documentation.
Pyrophoric Scale Passivation
Application of specialized chemical oxidation neutralizers to safely pacify volatile iron sulfide deposits before opening tanks.
Thermal Hydro-Jetting
High-temperature (95°C) 40,000 PSI automated washing to liquefy and strip viscous heavy hydrocarbon cakes.
Closed-Loop Sludge Evacuation
Continuous vacuum transfer to explosion-proof phase separation tankers for authorized hydrocarbon recycling.

How do you prevent explosions when cleaning tanks containing pyrophoric iron sulfide?
add
How do you prevent explosions when cleaning tanks containing pyrophoric iron sulfide?
Pyrophoric scale can self-ignite when exposed to atmospheric oxygen. We utilize continuous water fogging and specialized bio-degradable chemical passivating agents that neutralize the iron sulfide before and during hydro-jetting operations.
02
Are your technicians certified for offshore helicopter transfer and survival?
add
Are your technicians certified for offshore helicopter transfer and survival?
Yes. Our offshore strike teams maintain active BOSIET (Basic Offshore Safety Induction & Emergency Training) and HUET (Helicopter Underwater Escape Training) credentials.
03
