At our last virtual monthly meeting, Daniel Smith with Wood Group in Houston presented on “Transportation and Installation of Offshore Structures.”

Dan started the presentation by explaining the different design conditions to consider for offshore structures. It is very important to select the appropriate type of structure for field development. He then reviewed different load conditions used by structural engineers. Different types of offshore platforms were discussed throughout the presentation as well.

Dan presented the equipment and methods used to transport and install large offshore platforms. He then walked us through several of the installation challenges that he and his team took on in different projects.

Dan called out Allseas’ single-lift installation/decommissioning and pipelay vessel as a milestone because of the safe and successful installation of the 22,000-ton Drilling Platform topsides on the Norwegian continental shelf. This was the first platform installation performed by Pioneering Spirit, and the heaviest installation ever executed in a single lift offshore at that time (2018). Pioneering Spirit’s motion-compensated topsides lift system beams accurately positioned the topsides on an eight-legged steel jacket standing at 110 m water depth, after which the installation proceeded exactly as planned.
