Abstract
A stable offshore platform for surface or undersea work is provided by connecting a semi-submersible trailer unit with a workboat. Preferably, two columns of the trailer are joined by a beam member or truss, and this assembly is linked to the workboat via a truss-like trailer tongue with a ball swivel joint. When in transit, the semi-submersible unit is deballasted to a shallow draft condition and towed by the workboat.
