RUBBER FENDERS – BEYOND COMPARISON Today there are two major conceptions of how to make bow fenders for offshore wind Crew Transfer Vessels; rubber fenders and polyurethane fenders.
RG Seasight Fenders is a vital player in the offshore market with more than 250 rubber bow fenders delivered since 2008 which means that the Danish company is on more than fifty percent of the CTVs worldwide.
DIFFERENCE
People often ask the company to explain the difference between rubber bow fenders and polyurethane bow fenders. The fastest answer is to state that they are like apples and pears. Jesper Berg Kristensen, CEO at RG Seasight Fenders explains: “The foam inside polyurethane fenders deforms and becomes flat. Eventually, it will be difficult to comply with safety regulations, as the distance between vessel and wind turbine gets smaller. Rubber fenders on the other hand are solid and keep the shape; also in the long term.”
“Rubber fenders ensure twice as much friction than polyurethane fenders leading to a safer transition from vessel to wind turbine. Another advantage of great friction is the possibility of berthing under severe weather conditions giving more days at sea,” he emphasised.

MULTIPLE PURPOSES IN ONE FENDER The possibilities are endless, as rubber fenders can be modified and renovated, as every aspect of the fender is changeable. The fact that only five of the 250 delivered fenders are discarded, reflects this. The rest is still in use either in the original shape, modified, or renovated. Jesper concluded: “Rubber fenders are cost-effective in the long term as they, due to their solidness and durability, can be modified and renovated when needed. Polyurethane fenders on the other hand only have one duration. Therefore, from our point of view, we are back to apples and pears, as a polyurethane bow fender is a short-term solution.”

FRICTION, A CRUCIAL FACTOR
Friction between fender and boat landing is a crucial factor, as more friction gives a more stabled vessel when berthing. That means that an insufficient amount of friction easily causes the vessel to slide.
