Wet Bell Operations for Offshore

Wet Bell Operations is a specialised training component within the commercial diving programme, preparing you to operate and support wet bell systems safely during offshore diving operations. It develops the operational knowledge and practical understanding required to manage wet bell deployment, gas systems, emergency procedures, and distressed diver recovery in accordance with recognised offshore diving standards.

Wet bell systems are used in offshore and deeper commercial diving environments where controlled deployment, recovery, and diver support are critical. This module builds competence in wet bell design and specifications, panel operations, main and excursion umbilicals, onboard emergency gas systems, bailout planning, and standby diver coordination. Strong emphasis is placed on emergency response procedures, including recovery of distressed, injured, or unconscious divers, loss of gas supply, communication failure, and wet bell abandonment procedures.

You will learn structured offshore operational procedures, gas management requirements, decompression considerations, and emergency escalation protocols. Practical and scenario-based assessments reinforce safe decision-making, teamwork, and operational readiness in high-risk offshore environments.

Key areas covered include:

• Wet bell systems, diving baskets, and design specifications

• Deployment and recovery procedures

• Wet bell panel operations and gas management

• Main gas, excursion umbilicals, and onboard emergency gas systems

• Bailout planning and endurance calculations

• Standby diver procedures and umbilical markings

• Emergency response procedures (ERP)

• Distressed, injured, and unconscious diver recovery

• Loss of gas supply and communications response

• Gas contamination and wet bell abandonment

• Practical offshore skill assessment and emergency scenario training

By the end of this module, you will be able to support and operate wet bell systems safely, manage gas supplies and panel controls, execute deployment and recovery procedures, respond effectively to offshore emergencies, and demonstrate practical competence in wet bell operations in line with commercial diving safety standards.
