According to Deep Down, the first unique innovation is a subsea accumulator module (SAM), consisting of subsea deployment baskets (SDB) with attached accumulators, a built-in steel flying lead, a J-plate and a remote operated vehicle (ROV) panel. Several of these units will be shipped, the company said.
The SAM has been designed so that it may be transported without a wide load permit and set on a vessel. Once on the vessel, the wings of the SDB can be retracted, and the system will be pre-charged with pressurized control fluid. Thereafter, the SDB can be simply lifted off the deck of the vessel and placed on the seabed. Once on the ocean floor, the vessel will lift and pull out the built-in steel flying lead from the SAM with its own down-line cable.
The second innovation involves the development and manufacture of a unique deployment system to install very fragile, small-diameter fiber optic cables in deepwater environments. This deployment system is expected to greatly reduce the amount of stress on the fiber optic cable during installation.
The particular project involves the installation of approximately eight miles of fiber optic cable in 6,000 feet of water.
