Marine biofouling doesn't just slow your vessel down—it significantly increases fuel consumption, drives up operational costs, and can lead to compliance issues at your next port of call. At Marine One, we provide specialized underwater services and hull cleaning across all major Sri Lankan ports and anchorages, including Colombo, Galle, Hambantota, and Trincomalee.
Using class-approved commercial diving teams and state-of-the-art equipment, we execute safe, efficient, and environmentally compliant underwater operations without the need to dry dock—saving you both time and money while keeping your vessel on schedule.
Whether you need a routine pre-voyage hull polish or an urgent underwater inspection following suspected hull damage, Marine One delivers fast and highly effective subsea interventions.
Heavy marine growth on the hull dramatically increases drag. We provide high-performance underwater hull cleaning using specialized brush karts that effectively remove barnacles, weed, and slime without damaging the anti-fouling paint. A clean hull immediately restores vessel speed and significantly reduces fuel consumption.
Even minor fouling or calcification on your propeller can lead to a massive drop in hydrodynamic efficiency. Our divers perform multi-stage propeller polishing to achieve a Rupert Scale 'A' finish. This simple, cost-effective service instantly reduces engine thermal load and yields immediate fuel savings.
Need an urgent assessment of your vessel's underwater hull before a sale, after a grounding incident, or for class society requirements? We provide detailed, In-Water Surveys (IWS) equipped with live CCTV feeds and high-resolution photography. We inspect sea chests, rudder clearances, bilge keels, and propeller conditions.
When dry-docking is not an option, our certified underwater welders and technicians can perform critical emergency repairs right at the anchorage:
Don't let marine growth impact your bottom line. Contact Marine One to schedule an underwater inspection or hull cleaning during your next Sri Lankan port call.
