WHEN THE ENVIRONMENT IS DEMANDING,
THE CLEANING HAS TO BE DIFFERENT.
Conventional cleaning methods break down against maritime biofouling, heavy hydrocarbon cakes, and high-salinity corrosion. Chow Marine engineers purpose-built mobile hydro-demolition and decontamination packages capable of clearing hundreds of square meters of white-metal surface per shift.
Direct drydock deployment across St. Lawrence Seaway, Great Lakes, and North Atlantic offshore sectors with certified atmospheric scrubbers.
DEEP CLEANING WITHOUT COMPROMISE.
VESSEL & SHIP CLEANING
Hull de-fouling, cargo holds, ballast tanks, and heavy engine room degreasing under tight turnaround drydock schedules.
OIL RIG & OFFSHORE CLEANING
Drilling risers, production decks, flare systems, and marine splash-zone hydrocarbon decontamination.
INDUSTRIAL DEEP CLEANING
Chemical storage tanks, refinery transfer piping, heavy foundries, and hazardous industrial sludge extraction.
MARINE STRUCTURAL CLEANING
Drydocks, caissons, pier bulkheads, marine pilings, and navigable canal infrastructure maintenance.
VESSEL & SHIP CLEANING
Hull de-fouling, heavy cargo hold residue extraction, water ballast compartment descaling, and engine room fuel-oil degreasing to white metal standards.
BUILT FOR
THE HARD-TO-REACH.
PERFORMANCE MATTERS
WHEN THE ASSET CANNOT STOP.
Every drydock hour costs thousands in port retention fees. We eliminate demurrage risks through rapid mobilization and industrial equipment reliability.
DEEP-CLEANING EXPERTISE
UHP JETTING & THERMAL BLASTProprietary hydro-demolition units providing cold water and heated abrasive blasting up to 40,000 PSI. Capable of slicing thick elastomeric coatings, heavy sea scale, and polymerized hydrocarbons without base substrate damage.
MARINE & OFFSHORE FOCUS
MARITIME REGULATORY COMPLIANCENaval architects and marine superintendents rely on our familiarity with classification societies (ABS, Lloyd’s Register, DNV). We operate within IMO ballast regulations, MARPOL Annex waste limits, and drydock safety mandates.
SAFETY-FIRST OPERATIONS
CONFINED SPACE & HAZARDOUS GASEvery technician holds current confined-space rescue, working-at-heights, and offshore survival accreditations. Continuous four-gas telemetry monitoring and dedicated rescue watch teams ensure zero-tolerance protocol compliance.
RELIABLE EXECUTION
24/7 DOCK & HARBOR DISPATCHMobile response units stationed at our Hamilton headquarters mobilize across eastern Canadian ports within hours. Self-contained water storage, multi-gun pump trucks, and vacuum loaders operate independent of dockside utilities.
INDUSTRIES WE SERVE
MARINE
Deep-sea container vessels, Great Lakes bulk freighters, tugboats, articulated barges, and port authority piers requiring rigorous hull conditioning.
OFFSHORE
Semi-submersible drilling platforms, jack-ups, floating production storage and offloading units (FPSO), and deepwater subsea support structures.
OIL & GAS
Coastal refining infrastructure, crude marine terminal loading arms, hazardous storage tank farms, and long-run petrochemical transport pipelines.
HEAVY INDUSTRIAL
Blast furnace complexes, steel manufacturing plants, power generating turbine bays, and heavy vehicle foundries along Ontario's industrial corridor.

FREQUENTLY ASKED QUESTIONS.
Direct answers regarding hydro-demolition pressure ratings, drydock turnarounds, mobilization timelines, and environmental containment.
01
What hydro-blasting pressure ratings and standards do your crews deploy?
add
What hydro-blasting pressure ratings and standards do your crews deploy?
Our primary mobile units operate up to 40,000 PSI (Ultra-High-Pressure Waterjetting - UHPWJ), meeting SSPC-SP WJ-1/NACE WJ-1 specifications for bare metal surface preparation without abrasive grit embedding or profile damage.
02
How quickly can emergency and dockside response teams mobilize?
add
How quickly can emergency and dockside response teams mobilize?
From our central base in Hamilton, Ontario, rapid-response crews deploy within 4 to 12 hours across the Great Lakes and St. Lawrence Seaway corridor. Offshore and Atlantic deployment packages are coordinated via 24/7 harbor dispatch.
03
How do you handle hazardous runoff and MARPOL environmental compliance?
add
How do you handle hazardous runoff and MARPOL environmental compliance?
Every operation integrates closed-loop vacuum recovery and high-volume multi-stage filtration units. All wash water, hydrocarbon emulsions, and biofouling slurry are strictly contained, scrubbed, and processed in accordance with MARPOL Annex standards and provincial environmental ministries.
04
Are your technicians certified for hazardous confined spaces and offshore assets?
add
Are your technicians certified for hazardous confined spaces and offshore assets?
Yes. Every technician holds valid offshore safety certifications (BOSIET/HUET), confined-space entry permits, working-at-heights qualifications, and continuous multi-gas atmospheric telemetry monitoring protocols.
05
Can cleaning operations proceed concurrently with ongoing vessel refits?
add
Can cleaning operations proceed concurrently with ongoing vessel refits?
Yes. By utilizing localized blast containment curtains, negative-pressure dust/mist evacuation, and whisper-quiet Tier 4 diesel hydro units, our crews work alongside electrical, mechanical, and painting contractors without halting surrounding shipyard schedules.
