Abstract

The invention relates to floating offshore facilities, columnar in form, often referred to as spars comprising a body having an upper column, a main compartment and a lower leg joined together to define the spar, wherein the spar further comprises an articulation for connecting an end of the lower leg to the seabed, wherein the lower leg geometry has been configured as having a particular geometry that in combination with a particular residual buoyancy of the spar, and for any particular geometry of the upper column and main compartment and in any specific water depth, the spar provides a particular dynamic response to wind, wave and forces applied by sea currents. The invention also relates to methods for varying the dynamic response to wind, wave and forces applied by sea currents of the spar and to methods for transferring materials and personnel between a production facility such as the spar and at least one transportation apparatus such as a dynamically positioned vessel.
