The working area is decked with galvanized steel grating to ensure non slip safe operation and to reduce water entrapment. A-frame A rugged A-frame is provided to launch the wetbell over the ships side. The A-frame is designed to be rigid in operation and handle the required design loading as specified in Lloyd s requirements for offshore structures. As an additional safety feature for man riding purposes the A-frame is provided with safety stops should a failure in the rams or hydraulics occur. Wire sheaves - The A-frame is fitted with sheaves on the top of the frame and an emergency recovery pad eye is provided should all systems fail and a separate winch or manual system be needed to recover the bell. These sheaves provide movement in 3 axes thereby preventing the chance of the wire jumping off. In addition the wear on the sheave is uniform and any side movement due to currents or vessel movement will not create excessive shear forces on the pins. Hydraulic Cylinders Hydraulic cylinders are supplied with stainless steel shafts as a standard to provide trouble free operation in the marine environment. The cylinders are used for luffing the A-frame. Flow dividers are provided to ensure simultaneous extension of the rams. Dual hydraulic over centre valves are also hard piped onto the cylinders to prevent uncontrolled movement of the rams due to a loss of hydraulic pressure. This ensures a safe operation of the system at all times. Hydraulic piping All hydraulic pipe work is of mild steel construction hoses and cadmium plated fittings. The pipe work is securely fitted to the frame using pipe clamps. All flexible connections and interconnects are kept to a minimum. Safety protection - A safety chain is provided across the sea side of the A-frame and is clipped in position after launching. Safety eyelets are provided on the skid frame to clip operators in should they be working over the side. A safety rail is provided on the inside of the rams to prevent accidental damage from recovering the bell. The rails also provide support for the diver when exiting and entering.

7 Painting - The framework is shot blasted and painted to a marine grade paint specification. A Jotumastic or Carbomastic heavy duty marine aluminium primer with a polyurethane top coat. Final DFT is 200 microns plus. Main Wire Lift System The wetbell is lifted to and from the working depth using the main wire winch as the primary means. The winch is routed through the A-frame using standard sheave assemblies and is directly connected to the wetbell using a wire socket with castle nut and pin. The Offshore man rider winch specifications are as follows: Minimum lift capability Maximum lifting speed Wire diameter for 1,5T Maximum drum wire capacity Wire length supplied Drive system Braking Finish Approximate dimensions : 1.9 Ton (1900 kg) (1.9N) : operator controllable up to 20m per minute : 14mm non-spin : 100m of 14mm (4 layers) : 100 m : Direct hydraulic : 1.

Stainless Steel Safety guards are fitted : Length 950mm Width 650mm Height 890mm Weight 500kg Guide Wire System The guide wire system provides a means of guiding the bell to the sea bed and maintaining the bell in a set orientation and perpendicular position to the vessel. This reduces the effect of strong currents and vessel movements. The guide wire system also serves the purpose of providing a secondary means of recovery and is the reason for the guide wire winch being rated for man rider purposes. The winch has a two fold purchase with the standing part secured to the top of the A-frame. The winch is rated for approx 36m/min ascent speed (18/min actual two fold purchase). This is to provide adequate speed during work where surface decompression is required and the distance from sea level to system is high. Typically rig support where freeboard height is in excess of 20m. The clump weight supplied with the system is provided with dual sheave wheels and is provided with finger guard protection, etc. The clump weight weighs 400kgs.

With previous acrylic domes a complete spare dome was required to ensure a 100% redundancy should the dome be damaged. The hexagonal dome features the visual advantages of conventional

10 acrylic domes except with the benefits of being able to easily replace individual acrylic panes offshore. Should the acrylic panes not be available in an emergency, suitable steel plate can be used still providing a complete wetbell system with very low downtime potential. The diver recovery hoist and diver handles are an integral part of the hexagonal dome to assist divers within the bell. Stainless steel tubular construction Provides superb wear and corrosion resistance to the harsh marine environment. The base of the bell is mild steel, double dipped galvanised and painted. In addition all boltable interfaces are directly through the base plate thereby ensuring no threaded steel is open to the corrosive environment. All bolts are supplied with nylocks and spring washers. 10 additional mounting points are provided for equipment installed on the frame. Lifting points The bell is fitted with a central lifting point and three additional eyelets for attachment of the bell kellems grip and for emergency recovery. Guide wire system - Stainless steel guide wire guides with nylon bushes are provided for securing the bell to the guide wires. The bell is equipped as follows: Bell lighting - 2 x 100W underwater lights are provided mounted outside of the dome facing both entrance and exits to the wetbell. Umbilical storage Stainless steel horns for up to 45m umbilical lengths are provided. The horns are able to be quickly released to provide emergency intervention by the standby diver. Unconscious diver recovery system - For compliance to IMCA guidelines a diver recovery hoist is provided to lift an unconscious diver into the bell air space. Divers depth indicating gauge A gauge is provided for monitoring bell depth by the divers. Bell communication The wet bell is equiped with a talk-back speaker mounted on a stainless steel bracket in the top of the bell dome for communications between the divers in the bell and the operators at the dive control station Optional; Hydraulic Tools connector- In the bell 2 hydraulic handtools can be connectred, via a switch valve. Only 1 tool can be used at the same time. The bell life support systems are as follows: Onboard Gas Supply - 4x 50l 200 bar onboard gas supply cylinders with regulators and demand valves. These cylinders supply the divers air manifold with emergency air. Divers Manifold Each divers manifold has separate surface air supply, cross over valves, second stage demand regulators, bailout air supply hose whip for connecting to the divers helmet and HP contents gauges. Bell supply The bell supply is supplied from the standby diver supply and includes a dome vent valve. Hot water A hot water manifold is supplied for connection to the divers hot water system Pneumofathometer depth monitoring - provided for diver 1, diver 2, diver 3 and the bell. Oil filled Electrical box - An oil filled electrical box is supplied only on request. Our standard wetbell is directly coupled to the umbilical through inline subconn connectors. These connectors connect the divers umbilicals and the bell systems. This system provides less leak potential and reduces maintenance requirements. Should an oil filled electrical box be required the system will comprise of directly glanded umbilical electrical cables into the oil filled box. Wires will be junctioned and wired to bulkhead connectors. The box will be manufactured from stainless steel with an Acrylic securing plate. An oil pressure compensation system is also provided.

11 Hydraulic Control Panel The hydraulic control panel provides all the hydraulic controls for bell and guide wire weight deployment and umbilical handling. It is positioned on the frame to provide the operator with a clear view of the bell recovery and launch position. Controls are provided for: A-frame luff out and in Main wire in and out Guide wire in and out Pressure gauges are provided for: Main pump Hydraulic system pressure Secondary pump hydraulic system pressure Main Electrical Switchboard The main electrical switchboard provides controls for the wet bell, wet bell handling system and diving control room.
