Subsea Accumulator Module (SAM)

Deep Down, Inc. developed the Subsea Accumulator Module (SAM), an innovative piece of subsea installation equipment in order to address our clients’ critical issues in the offshore industry. The SAM consists of Subsea Deployment Baskets (SDB) with attached accumulators, built-in steel flying lead, J-plate and a Remote Operated Vehicle (ROV) panel.

The SAM was 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 deployed 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 lifts and pulls out the built-in steel flying lead from the SAM with its own downline cable. An ROV may be used to guide the steel flying lead from the SAM and connect it to the Hydraulic Distribution Manifold (HDM). The ROV is further deployed to open valves wherein the SAM can provide plug-and-play subsea accumulation capabilities to augment the existing subsea distribution control system with localized volume and pressure control features. The SAM also serves as an anode skid designed to carry additional anodes. It is grounded to the structure in order to provide additional cathodic protection to the HDM. The entire SAM can also be easily retrieved and serviced on deck, further improving a client’s ability to retrieve subsea hardware.
