N2 - On offshore platforms the purpose of fenders is to protect the
oil-risers against minor accidental collisions with supply
vessels. Normally, the fender is designed by use of thin-walled
tubes. However, the tube itself is not capable of resisting the
impact load of the boat. Therefore, alternative designs are
searched for the fender.Today, an often used improvement of the
fender is to fill it with grout or concrete. However, this
improvement is not optimal since the fillings increase the weight
of the fender beyond the crane capacity of the platform. Thus,
crane boats are needed for the installation of the fender and
perhaps for removing it if new oil-risers are to be initialled.
The use of crane boats is expensive and weather-dependent.With
these effect sin mind, a study of the energy absorption in the
fender system, i.e. the fender itself and the frame, is needed for
further development of the fender design.
