We offer you a variety of underwater expertise, for example:
• Thruster changes
• Underwater welding
• Propeller polishing
• Hull cleaning
Poor hull condition has often been noticed to be as a cause of fall off in performance with time in service, although in practice a significant contribution to the reduction in performance may well have been due to propeller roughness

The curve shows the relation between the propeller roughness and the loss of power
