SERVICES
Specialized cleaning for demanding maritime & offshore environments.
Engineered ultra-high-pressure decontamination, hull refurbishment, offshore rig maintenance, and heavy industrial extraction operating under Transport Canada, MARPOL Annex I-VI, and SSPC/NACE protocols.
Engineered Precision In High-Risk Waters
Precision execution across heavy maritime vessels, offshore exploration rigs, and critical shore-side petrochemical installations with rapid emergency mobilization.
Ship & Vessel Deep Cleaning
Full hull bio-fouling stripping, cargo hold washing, ballast tank descaling, and engine room degreasing under tight drydock turnaround schedules. Certified zero-oxygen confined-space entry teams.
Oil Rig & Offshore Cleaning
Semi-submersible and jack-up drilling platforms, splash-zone structural washdown, flare stack decoking, conductor pipe jetting, and hazardous marine hydrocarbon recovery with explosion-proof equipment.
Hydro-Demolition & Deep Extraction
Petrochemical storage tanks, refinery transfer piping, heavy foundry degreasing, heat exchanger tube bundle hydro-lancing, and non-destructive automated hydro-demolition of degraded maritime concrete.
Marine Structural & Pier Services
Drydock caisson restoration, port pier bulkheads, canal locks, submerged marine pilings, and navigable waterway intake maintenance utilizing hydraulic cavitation cleaning and splash-zone rope access.
DELIVERING SPECIFICATION-GRADE CLEANLINESS
Chow Marine does not rely on subjective inspection. Every square meter cleaned or decontaminated is calibrated to recognized international marine engineering and protective coatings protocols.
Surface Cleanliness Standards
Complete removal of mill scale, rust, marine growth, bio-films, and deteriorated paint coatings down to bare substrate.
Pressure & Thermal Spectrum
Continuous-duty diesel and electric skid-mounted pumping units engineered for brutal marine atmospheres and continuous operation.
Environmental & MARPOL Compliance
Full containment, waste-stream capture, filtration, and certified transport without a single drop entering navigable waters.
