Radiation, Diffraction Analyses on Side by Side Applications

Offshore barge mooring is considered a critical operation. The vessels need to be in close proximity, but may under no circumstance collide. Mooring lines and fenders are installed to keep the vessels in place. Experience has shown that lines tend to break occasionally; one of the reasons for this can be the interaction effect of the two vessels...

Multiaxial fatigue criteria for offshore mooring chains subjected to out-of-plane bending

The out-of-plane bending of offshore mooring chains leads to a rapid deterioration of the chain, ultimately leading to failure in a period that is a fraction of the design-life. The deformation of the contact surface of the chainlinks leads to the interlocking of the link. This in turn causes the chain to behave like a bending beam. The...
