Subsea Accumulator Module

Deep Down’s Subsea Accumulator Module (SAM) is designed to provide customers with a multifaceted subsea tool to address cathodic protection (CP) and provide a subsea reservoir. Consisting of a Subsea Deployment Basket (SDB), built-in steel flying lead, J-plate and Remote Operated Vehicle (ROV) panel, the SAM has a compact design that allows for rapid transport without the need for permits.

The SAM is pre-charged with pressurized control fluid enabling plug-n-play subsea accumulation capabilities to augment the existing subsea distribution control system with localized volume and pressure control features. An ROV can guide the steel flying lead from the SAM and connect it to a hydraulic connection panel. Additionally, a funnel serves as a protective cage for product when in the stowed mode, and integrates flying CP grounding cable with clamp that is ROV installable to provide additional CP protection to subsea structures. The SAM can carry additional anodes based on customer requirements.
