Patent abstract
A spar-type offshore platform includes a buoyant upper hull structure having a lower end to which is detachably connected a buoyant lower module. A plurality of mooring line assemblies is connected to the lower module, the total weight of the mooring line assemblies being sufficient to sink the lower module. A method of separating the upper hull structure from the lower module includes disconnecting the lower module from the lower end of the upper hull structure, and then allowing the weight of the mooring line assemblies to sink the lower module.
