Wet Bell for Class II

Introduction to Wet Bell Operations

Wet Bell Operations is a specialized course designed to equip participants with the essential knowledge and skills required for safe and effective underwater operations using wet bells. Wet bells serve as critical platforms for transporting divers to and from underwater work sites, offering a controlled environment that enhances both safety and operational efficiency. This course will cover the design, operation, and safety protocols associated with wet bell systems, ensuring that divers can perform their tasks effectively while minimizing risks.

Key Features of Wet Bell Design:

• Capacity and Comfort: A wet bell must accommodate at least two divers wearing bailout bottles in a non-cramped position. This design consideration is vital to ensure that divers can operate comfortably and efficiently within the bell.
• Safety Mechanisms: The wet bell should be engineered to prevent divers or their equipment from being inadvertently pulled from it. This includes the incorporation of internal handholds, which provide divers with secure points to hold onto during transit, and a stable design that prevents tipping or spinning.
• Depth Management: In scenarios where the water depth exceeds the planned maximum dive depth, it is crucial that the wet bell has a reliable system in place to prevent it from descending beyond this limit in the event of a winch failure. This feature is essential for maintaining diver safety during operations.
• Operational Protocols: At the conclusion of each dive, it is imperative that the diving supervisor does not lift the bell until divers have confirmed that their umbilicals are stowed properly and that safety chains or gates are securely in place. This protocol ensures that all safety measures are adhered to before any ascent occurs.

Through this course, participants will gain an understanding of these critical aspects, alongside practical training in operating wet bells safely and effectively in various underwater environments.
