    Dive Control Panels and Scuba Replacement Packages (SRP)

    Dive control panels and Scuba Replacement Packages sit at the surface end of a surface-supplied spread, routing breathing gas, pneumofathometer depth readings and comms out to each diver. We supply them for sale or hire, new or used, shipped worldwide door to door, and build bespoke panels to IMCA/HSE standards.

    Our range covers wall-mounted panels for fixed installations and cased portable panels for work that travels, in two and three diver configurations, running air, nitrox or mixed gas. Portable offshore builds are made to IMCA D040, the DESIGN guidance for mobile and portable surface supplied systems; nitrox and mixed gas builds to IMCA D037.

    Specifying starts with the spread. A fixed vessel or shore installation takes a wall mount; work moving between sites needs a cased portable. Diver count sets the panel, gas sets the build. For a complete control station rather than a panel alone, see our Containerised Dive Systems and Trailer-mounted Dive Control System.

    Tell us the diver count, the gas and how the spread will travel, and we will specify a panel and quote for supply or hire.

    Frequently Asked Questions

    A Scuba Replacement Package (SRP) is a surface-supplied diving system used in place of traditional self-contained underwater breathing apparatus (SCUBA) for many commercial diving operations. Surface-Supply is generally preferred, and required depending on the applicable regulations, standards, and scope of work, because it provides the diver with a breathing gas supply from the surface rather than from limited back-mounted cylinders. This improves diver endurance, allows continuous communications and monitoring, and gives the dive supervisor greater oversight of the diver’s air supply, depth, and safety throughout the operation.

    Dive control panels act as the central nervous system for underwater life support. They are engineered with multiple inlets to connect both primary low-pressure compressors and secondary high-pressure backup cylinders. If the primary air supply experiences a mechanical failure, the dive supervisor can instantly switch to the secondary high-pressure bank using dedicated crossover valves. This seamless transition ensures the diver experiences no interruption in their breathing gas, providing the vital time needed to safely abort the dive and return to the surface.

    Accurate depth monitoring is critical for preventing decompression sickness and managing dive profiles safely. Modern dive control panels incorporate highly calibrated pneumofathometer (pneumo) gauges. A dedicated pneumo hose runs from the panel directly to the diver. By pushing a controlled burst of air down this hose to clear it of water, the supervisor reads the resulting back-pressure on the panel gauge. This provides an extremely precise, real-time measurement of the diver’s exact depth, independently of the diver’s own depth gauges.

    Yes, many Scuba Replacement Packages and control panels are specifically designed to support two or even three divers simultaneously. However, safety regulations dictate that each diver must have an entirely independent air routing system within the panel. A standard two-diver panel will feature separate depth gauges, pressure regulators, and communication channels for Diver 1 and Diver 2. In commercial operations, one of these connections is typically reserved for the standby diver, who must be fully kitted and ready to deploy instantly in the event of an underwater emergency.

    When sourcing life-support equipment for commercial diving, adherence to stringent industry standards is non-negotiable. You should ensure that the control panels and SRPs comply with the guidelines set forth by the International Marine Contractors Association (IMCA) and your regional regulatory bodies, such as the Health and Safety Executive (HSE) in the UK. Equipment should feature certified, calibrated gauges, clearly labelled valves, robust protective casing, and comprehensive testing documentation to prove it meets the rigorous demands of the commercial marine sector.
