For this USD 150,000 project, the scope was to determine the temporary reinforcement needed for the aft port of a damaged semi-submersible platform in order to maintain the vessel’s certification and keep it operating prior to being brought back to the shipyard for
permanent repairs. The team had two to three weeks to prove the temporary fix was viable and selected SACS even though SACS is not
normally used for this type of floating structure.
Diplamar used SACS to quickly develop models to assess the current condition of the damaged element, then determine the structural
behavior of the bracing before and after the damage. A support structure was designed, and the behavior of the reinforced bracing was
verified. This enabled the vessel to remain certified and complete its program before being returned to the shipyard for maintenance.

Deck Supporting Frame to Facilitate Installation of Four-legged 6500 MT Process Deck
Located off the east coast of India, the process-cum-living quarter platform project for Gujarat State Petroleum Corporation Ltd. involved
design and analysis of a deck supporting frame (DSF) to facilitate installation of a four-legged process deck. The platform’s three levels
included modules for the turbine generator, living quarters, and gas dehydration unit.
Weighing 6,500 metric tons, the deck could not be lifted by the available offshore barge crane. Engineers India Limited split the deck into
two parts and introduced the DSF for support. Using SACS to finalize the DSF configuration and design optimization helped to finish the task
within the three-to-four month schedule. Bentley software was used for design and analysis of the in-place condition, pre-service condition,
installation sequencing, and stability at every stage of the installation.
