ABSTRACT:
A semi-submersible pipelaying vessel has an improved configuration and structure for laying pipe wherein the pipeline path extends along a port or starboard side of the vessel. The pipeline path passes through the upper deck member of the vessel and then through a supporting column member of the vessel. A cantilevered overhang or deck member extension is not required. The pipe is supported along the pipeline path by a plurality of pipeline supports for providing the pipe at the stern of the vessel with the correct inclination with respect to the water surface. The slotted column advantageously provides protection for the pipeline below the deck level with respect to lateral wave action forces and added vessel stability and/or work area efficiency.
