From the first site survey to the final corrosion check, every rig and port facility follows the same disciplined workflow. We map the affected steel, set pressure levels per surface, and document each stage so your team knows exactly what happens next.
A chronological record of how Atlanticdemoussage structures marine maintenance campaigns, from initial site assessment to final corrosion verification. Each phase has defined deliverables and inspection checkpoints.
Engineers board the rig or port facility to map biofouling density, measure steel thickness, and identify high-risk zones where moss has penetrated protective coatings. The survey produces a cleaning priority matrix that determines equipment positioning and crew allocation.
A 4-square-meter test patch is treated with calibrated hydroblasting to confirm the correct pressure range for the specific steel grade and moss thickness. Readings are logged and compared against baseline corrosion data before full-scale work begins.
Crews work in rotating shifts across the structure, removing moss, barnacles, and rust scale with high-pressure industrial hoses. Each section is documented with before-and-after thickness readings, and any exposed pitting is flagged for immediate anti-corrosion treatment.
Cleaned surfaces receive a marine-grade anti-corrosion layer applied under controlled humidity conditions. Coating thickness is verified with a dry-film gauge, and touch-up work is scheduled for any areas that fail the adhesion test.
A third-party inspector reviews the treated sections against the original survey data. The client receives a full report with corrosion readings, coating certificates, and a recommended re-treatment interval based on the site's exposure profile.
A return visit checks for early moss regrowth and coating wear at high-stress joints. Findings are compared with the handover baseline, and any anomalies are corrected under the maintenance agreement before they escalate into structural issues.
Every stage of our process is built around one outcome: keeping steel structures free of moss, scale, and corrosion without interrupting your operations. Here is what that means in practice.
We schedule hydroblasting and moss removal around your shift patterns and weather windows, so critical platforms stay accessible when you need them.
Our inspection pass maps every patch of marine growth and rust scale before cleaning begins, so the crew treats the source, not just the visible stain.
By removing moss and salt deposits down to bare metal, we give protective coatings a clean base that holds up through repeated tidal exposure.
After each visit you receive a log of treated zones, pressure levels used, and remaining risk areas, so your maintenance records stay audit-ready.
We bring industrial pumps and nozzle rigs rated for thick barnacle layers and dense moss, not consumer-grade washers that stall on the first pass.
Work near ballast tanks, leg interiors, and under-deck areas follows a strict permit system, with gas testing and harness checks before any hose is opened.
