MaxiDive completed a CRMS Bio-Fouling Inspection and Cleaning operation at Laem Chabang Port, Thailand, supporting vessel biofouling compliance through underwater inspection, targeted cleaning and structured visual documentation.
The operation was carried out on a large commercial vessel alongside port facilities, where access, timing and safety coordination are essential. The MaxiDive diving team performed the underwater work using hydraulic tools, hand tools, TG-7 cleaning equipment and GoPro-based photo/video documentation to record the inspected and cleaned areas.
CRMS Bio-Fouling Inspection and Cleaning scope
The scope of work included underwater inspection and cleaning of selected hull and niche areas in accordance with CRMS biofouling requirements. The inspection focused on documenting the vessel’s underwater condition, identifying marine growth, supporting cleaning where required, and providing clear visual records for operational and compliance review.
Biofouling control is an important part of vessel management, especially for vessels operating internationally or preparing for ports with strict marine growth requirements. Even when a vessel is structurally sound, slime layer, weed, shell growth or early-stage fouling can develop around hull surfaces, appendages, sea chest areas, discharge openings and propeller-related zones. These areas require careful inspection because they are often more difficult to access and can retain marine organisms longer than flat hull surfaces.
Underwater inspection at Laem Chabang Port
During the operation, the diving team worked in calm sea conditions with limited underwater visibility. This required controlled positioning, close-range inspection and systematic documentation of the underwater areas.
The inspection covered accessible hull zones and key underwater reference points, including hull plating, appendages, sea chest and discharge areas, propeller-related areas, rudder zones and other niche areas where marine growth can accumulate. The objective was not only to clean visible fouling but also to provide usable visual evidence showing the condition before, during and after the operation.
For vessel managers and technical superintendents, this type of documentation is valuable because it supports decision-making, compliance preparation and maintenance planning without requiring the vessel to leave the port schedule for drydock.
Cleaning and documentation for biofouling compliance
The cleaning work was performed using a combination of hydraulic and hand tools depending on access, surface condition and the type of marine growth found. This approach allows the diving team to remove fouling from selected areas while working carefully around sensitive fittings, coatings, grids, outlets and underwater appendages.
Photo and video records were taken to document the condition of the inspected areas. This is particularly important for CRMS and NZ MPI-related support, where clear underwater evidence may be required to confirm the vessel’s biofouling status and cleaning results.
The operation also included coordination from the vessel side and support craft, allowing the commercial diving team to manage equipment, diver communication and inspection coverage efficiently while the vessel remained at Laem Chabang Port.
Why CRMS biofouling work matters
Biofouling can affect vessel efficiency, compliance readiness and operational planning. Marine growth on the hull and niche areas may increase drag, reduce performance and create additional inspection requirements before the vessel enters certain jurisdictions.
A structured CRMS Bio-Fouling Inspection and Cleaning operation helps vessel operators reduce these risks by combining underwater cleaning with technical documentation. Instead of relying on visual assumptions from above the waterline, the vessel operator receives direct underwater evidence from the diving team.
For commercial vessels calling Thailand, MaxiDive provides this support across major ports and anchorages, including Laem Chabang Port, Koh Si Chang Anchorage, Sriracha, Sattahip, Map Ta Phut and other operating locations.
