Phoenix International Holdings, Inc. (Phoenix) announced the award of two deepwater underwater maintenance projects in the Green Canyon area of the Gulf of Mexico.
Contract work includes the removal and replacement of six non-wet mateable tension monitoring system cables on the tendons of a Tension Leg Platform (TLP), removal of fairings associated with the installation of the TLP, recovery of storm debris from the top of the hull, and replacement of rigging associated with in-situ oceanographic sensors. Proof of concept testing will be completed on the cable systems prior to project execution using in-water project mock-ups and the freshwater test tank located at the Phoenix Bayou Vista, Louisiana operations facility. Modifications to the concept will be made as necessary to assure actual operations hours are kept to a minimum. The offshore work will be conducted in water depths of 80-175 fsw, and use a combination of surface-supplied diving and Phoenix’s HARDSUIT™ Atmospheric Diving System.
Both projects will be supported by the M/V Anne Candies, a 240 ft. DP II vessel on long term charter to Phoenix from Otto Candies, LLC of Des Allemands, Louisiana.
