WETBELL, D037

The A frame with Skid

Keeping in mind the restrictions on space and the weight of the wet bell Lars system, the base has been designed to ensure minimum utilisation with maximum effect on the diving vessel or barge. The system consists of the main A frame the hydraulic power packs (2 completely independent units built into one frame), hydraulically operated rams (SS Shaft) for extending and resting the A frame (Double acting bore 80mm x rod 56 mm x ST 800mm, welded with dual lock valve 2 sets), Basket and guide weight, 2 x hydraulic winches (one for wetbell and one for guide wire). The design allows the main winch to be located on the base next to the power pack, and the guide winch to be installed on the platform raised above the power pack for ease of operation. The electrics are Star Delta starters, and can be operated from the power pack or on the platform as deemed fit during operation. The paint is double epoxy heavy duty marine grade paint.

Main Wire Lift System
The main wire winch lifts the bell to and from working depth. The wire runs though the sheave assemblies and is connected to the bell. The winch is Offshore man rider certified by manufacturer and witnessed by DNV.

Guide Wire System
To maintain the bell in correct orientation and in relative position to the vessel, the guide wire system is used. It negates the movements of the currents when the bell in the water and compensates for vessel movements also.  The guide wire system is also the secondary recovery and is certified for man riding. It works on a twofold system, and is secured to the A frame.

Two Diver Wet Bell Unit With Acrylic Windows
The wet bell is designed to accommodate two divers. The dome consists of acrylic panes, fitted individually on the dome In case of any damage to the panes offshore, it is easy to replace the damaged units with spare acrylic panes , or even steel plates can be fitted on them to ensure continuity of diving. Built of stainless steel, round steel tubes are used to prevent accidental cuts to the diver during entry / exit of the bell.
