18 The diving bell was designed by Mara Engineering and is rated at 300msw. The bell has a 600mm side hatch and a 700mm bottom hatch. The bell mates to the trunking via the side hatch. There are nine 220mm view ports of which one is utilized for the internal observation camera. External lighting is provided by three Deep Sea Power and Light Multi-Sea Lights each rated at 120 volts, 250 watts. These are mounted to port and starboard each producing 4,750 lumens. Three-(3) ground fault interrupters monitor topside power to the diving bell Diving Bell Onboard Gas: Ten 50 liter 200 bar cylinders provide bell onboard gas. These are divided into three separate banks of three cylinders each for HeO2 diving mix. One cylinder is provided of pure oxygen for metabolic make-up. This system has a safety interlock that prevents valves from being open at the same time. A one liter buffer cylinder coupled to the interlock provides that not more than one liter of oxygen can be added to the bell at a time. The HeO2 diving mix banks are regulated by external TESCOM dome loaded regulators. An external IMF D110 Bell Oxygen Safety Regulator regulates the metabolic oxygen cylinder BELL EMERGENCY EQUIPMENT Emergency equipment includes the ability to jettison the main wire, guide wires and main umbilical all from inside the bell. The bell also carries an emergency battery power supply, 120 ampere hours at 24-volts. The bell ballast weight of 2.72 tonnes has a two-(2) stage release with safety chains. A SONARDYNE type 7192 emergency transponder with a reply frequency of 37.5 khz is mounted on top of the bell. In addition there is another SONARDYNE 7656 mini transponder with a reply frequency of khz which the vessel can interrogate. A SUBCOM 2000B through water communication system provides backup communications between the divers and dive control. DIVEX SSS Bell survival kits are also installed in the bell BELL UMBILICAL The bell is serviced through a 92mm diameter Fibron umbilical with a woven knit outer sheathing for protection.

19 11.5 DIVERS GAS RECLAIM / COMPRESSORS The diver s gas re-claim system is a Divex electric driven Gas Mizer system with dual Williams & James 651 electric compressors. This unit is capable of providing up to 90% reclaim for two divers, in addition to providing a backu p source for scrubbing of the bell atmosphere. The operational range of this unit is from 20 to 300msw. The diving system gas reclaim unit is comprised of a gas bag, one Compair 5437, high-pressure gas compressor, with a haskel gas transfer package as a back-up with a Divex Gaspure filtration package and a Divex Helipure Membrane Gas /Separation system. All exhausted gas from the diving system is piped to the gas bag before being re-compressed via the Compair 5437 and then filtered through the Gaspure which is capable of processing 100,000 cubic feet of gas before servicing is required. The Helipure is capable of removing the oxygen from a diving mix and returning pure helium to a storage cylinder. Typical recovery is around 90%. One Bauer K15 high pressure air compressor and a Delmonox filtration unit provide grade D HP air to the diving system 11.6 CONTROL ROOMS Saturation control is located on the tween deck above the main chamber room and adjacent to Chamber 1. The emergency power switching gear for the life support equipment is located in saturation control. Primary and secondary communications to the diving system are installed with helium speech un-scramblers. A Drowcon oxygen monitoring system for the gas storage areas is also located in saturation control. Dive control is located on the bottom deck adjacent to ROV control and the bell moonpool room. The emergency power switching gear for the bell hydraulic handling system is located in dive control. The controls for the bell handling system are also located in dive control AIR DIVING The diving system is also equipped with a surface air diving package, comprised of the following items: Two air driven surface diving stages with clump weights which can also be used for recovery in an Emergency. The air diving station located on the veranda deck. Built in Quincy 390 low pressure diving air compressor with filters and 250 gallon volume tank. Four high pressure banks in built to the ships system, comprised of nine 50 liter 200 bar cylinders each, provide backup diving air. Also on the verandah deck there is a bank of 8 high pressure cylinders at 50ltr, 160Bar, which can also be used for back up air supply. Two Deck Decompression Chambers located on the veranda deck forward of the dive station.
