FMS and Frog Cygnus perform Hull cleaning on SCA OBBOLA

FMS and Frog Cygnus perform hull cleaning on SCA OBBALA.

Increased fuel consumption of a vessel can often be due to the hull being overgrown. One quick and effective method to remove this is to clean with the help of high pressure water and ROV.The cleaning can normally be carried out at the quay during the ship’s loading and unloading. The marine fouling is removed without damaging the hull color. Furthermore, with planned cleaning intervals, environmentally friendly ship paint can be used.
