The Importance of Hull Cleaning for Vessel Energy Performance

Regular hull cleaning is one of the most cost-effective maintenance operations for shipowners. A hull fouled by marine organisms (biofouling) can increase hydrodynamic resistance by 10 to 16%, leading to significant fuel overconsumption.

The Economic Stakes

According to IMO studies, biofouling represents:

5 to 10% additional fuel consumption
A proportional increase in CO₂ emissions
An increased risk of corrosion and structural damage
Significant long-term operational costs

Our Approach at Ray's Company & Services

At Ray's Company, we carry out high-pressure cleaning and mechanical brushing of the underwater hull, while respecting anti-fouling standards. Our professional divers work directly in the port of Abidjan or San Pedro, without prolonged vessel downtime.

Equipment Used

High-pressure cleaners
Adapted hydraulic brushes
Manual scrapers for delicate areas
Latest-generation hydraulic pumps

HSE Procedure

Each intervention is preceded by a safety briefing, a pre-dive checklist and permanent monitoring by our surface team. Our divers are certified and trained in emergency procedures.

Measured Results

After a Ray's Company intervention, our clients observe:

Immediate reduction in fuel consumption
Improved navigation performance
Extended life of anti-fouling paints
Reduced corrosion risks
