MaxiDive completed a CRMS Bio-Fouling Inspection at Laem Chabang Port, Thailand, supporting vessel biofouling assessment through systematic underwater inspection and structured visual documentation.
The operation was carried out on a large commercial vessel alongside port facilities, where access, timing, diver communication and coordination with the vessel are essential.
The MaxiDive commercial diving team examined accessible underwater hull and niche areas and produced photo and video records to document the observed condition for technical and compliance review.
CRMS Bio-Fouling Inspection Scope
The CRMS Bio-Fouling Inspection focused on documenting the vessel’s underwater condition and identifying the presence, location and extent of visible marine growth on accessible hull surfaces and niche areas.
Inspection coverage included selected underwater areas where biofouling may accumulate and where clear visual evidence is particularly valuable for vessel managers and technical departments.
The objective was to provide a structured underwater record that could support operational planning, biofouling assessment and subsequent technical decisions.
Biofouling management is an important consideration for vessels operating internationally, particularly when entering jurisdictions with specific biofouling requirements.
Even when the primary hull structure remains in satisfactory condition, slime, weed, shell growth and other marine organisms may be present on underwater surfaces, appendages and niche areas.
Systematic inspection helps identify these conditions and provides technical personnel with direct underwater evidence.
Underwater inspection at Laem Chabang Port
During the operation, the commercial diving team worked under limited underwater visibility, requiring controlled positioning and close-range observation of the inspected areas.
Accessible underwater reference points included:
hull plating;
sea chest and grating areas;
discharge and overboard openings;
propeller-related areas;
rudder areas;
underwater appendages;
selected niche areas.
Each accessible area was visually assessed and documented according to the inspection scope.
For vessel managers and technical superintendents, this type of underwater inspection provides useful information without requiring the vessel to leave its operating schedule for dry docking solely for visual assessment.
Underwater Documentation for Biofouling Assessment
Clear documentation is a key part of a professional biofouling inspection.
Photo and video records allow the vessel’s technical team to review underwater conditions after completion of the diving operation and provide a visual reference for further operational or compliance-related decisions.
The inspection documentation can help show:
location of visible marine growth;
condition of accessible hull surfaces;
condition of selected underwater appendages;
biofouling observed in niche areas;
condition of sea chest and grating areas;
condition around overboard openings;
general underwater hull condition.
This structured evidence provides vessel operators with a clearer understanding of the underwater condition than observations made from above the waterline.
Why CRMS Bio-Fouling Inspection Matters
Biofouling can affect vessel operational planning and readiness for international voyages.
Niche areas are particularly important because marine organisms may remain around gratings, appendages, recesses, propeller-related areas and other locations that are difficult to assess without underwater access.
A professional CRMS Bio-Fouling Inspection provides vessel managers with direct visual evidence from below the waterline.
This information can support technical review, voyage preparation and decisions regarding any further action that may be required.
Accurate documentation is also valuable when vessel condition needs to be communicated between shipowners, managers, technical superintendents, agents and other relevant stakeholders.
