The correct hull, deck and structure maintenance

Ship maintenance is of capital importance, always to be taken into consideration even if the ship safely steers away from accidents. Just navigating the seas degrades the hull, suffering abrasion and corrosion. Adequate maintenance and repairs does more than embellish the ship, it favours a more efficient sailing with less friction. The vessel carries itself better, gaining speed and displacement, important aspects in a world where sea freight and tourist cruises have kept growing in number.

Deterioration of hull

The causes behind the degradation of the ship’s hull range from those that are natural, like the friction caused by sea water on the hull, corrosion, collision with small floating objects, scratches on the paint due to mooring operation, etc.

Corrosion

Corrosion is a natural process which reduces metallic elements back to their original state, damaging structural components. It occurs when oxygen and humidity contact a metal surface. Regardless of area size, corrosion must be prevented early.

Factors accelerating corrosion include:

• Proximity of different metals
• Metal composition
• Surface deformation
• Internal tension

Biodegradation and biofouling

Biofouling occurs when microbiological organisms adhere to the hull, affecting metal integrity and increasing drag. When detached, these organisms may strip paint and insulation, exposing metal to corrosion. Use antifouling paints and periodic cleaning to prevent this.

Mechanical deterioration and damage

• Friction corrosion: Occurs between water and hull surface.
• Erosion: When water attacks weak points on the hull.
• Cavitation corrosion: Caused by vibrations, especially around turbines and propellers.

Protecting the hull

Maintenance is key to a vessel’s health and efficiency. Suisca Group offers comprehensive services including hull cleaning, painting, polishing, and maintenance. These tasks reduce damage and ensure readiness for tight schedules.

Protection against corrosion

Our experienced teams handle deep cleaning, polishing, and multilayer painting to guard against corrosion. Priming ensures uniformity and protection, boosting paint effectiveness.

Anti-fouling paint

Anti-fouling paint contains biocides to slow down marine organism growth on hulls. These coatings improve ship performance, especially for vessels anchored or moored for extended periods.
