Invention:
This invention introduces a system and method to protect divers from hazardous energy when working with underwater powered tools, addressing the risks associated with power tool operations in underwater environments. It features an isolation manifold operated by a secondary diver to manage power flow to tools without needing to rely on verbal communication with topside support. The manifold integrates pressure relief mechanisms before and after a ball valve, ensuring that hazardous energy from pneumatic, hydraulic, or water-powered tools is safely controlled. The isolation of energy ensures that tools and supply lines are not over-pressurized when operating or during an ascent from depth. This system enhances diver safety by enabling in-water control of hazardous energy and rapid intervention during emergencies or tool maintenance.
Background:
Underwater powered tools are critical for a range of tasks, from construction to salvage operations. However, these tools pose significant risks, including uncontrollable activation due to trigger failure or over-pressurization. Current safety protocols rely heavily on verbal communication with topside operators to shut off power, which can be slow and unreliable in emergencies. The diver uses a switch or trigger to power the tool which is where the potential threat of hazardous energy comes into play. Normally, this control is applied through voice communications from the diver to topside, but with this method there will be no need for verbal communication to topside. This invention addresses the gap by enabling direct, real-time isolation of hazardous energy by a diver in the water, improving operational safety, efficiency, and compliance with regulatory requirements.
Applications:
- Commercial diving operations
- Salvage and recovery operations
- Underwater welding
- Oil and gas pipeline installation
Advantages:
- Safer diving operations
- Better real-time control of hazardous energy underwater
- Better training and regulatory compliance
- Improved pressure management
