Coupled Mini-TLP Barge Response in Random Seas

摘要

The response behavior of a coupled mini-TLP and tender barge in head and beam West African sea conditions is studied. Both vessels are independently moored, and coupling is introduced through a fender and breast line system. The dynamic response of the mini-TLP/barge system in uncoupled and coupled configurations is of particular interest. The experimental data obtained during the model test program are characterized using statistical parameters, correlation functions, spectra and coherence functions. It is confirmed that the connection system reduces the horizontal vessel motions of the barge, and that the forces exerted on the fender system are quite sensitive to sea heading conditions.
