4 System Components 1. Control Van The control van is a standard ABS approved 20 foot container split into two compartments, one compartment houses the life support control panels for the DDC/TUP/SPHL or HRC. The control panel space also houses the main electrical distribution panel and two 35KVA, 440/230V transformers. The control space is also fitted out with a fire alarm panel, Ambient O 2 sensor with battery backup and a repeater unit installed in the machinery space. The second compartment houses two Control Master Units (CMU), these units are designed to control the temperature and humidity within the DDC and TUP. Also within the second compartment is one portable water unit designed to supply domestic water into the TUP. The control van has a total weight of 8 metric tons and is supplied with its own dedicated lifting slings. The machinery space partition of the HRF container is fitted with a louver and extraction fan to maintain temperatures and air flow past the units. There is also an emergency light and an ambient O 2 repeater unit mounted in the space. 2. Living Chamber A large single lock chamber is mounted on the main skid together with the TUP chamber. They are both protected by heavy steel framework which also acts to support the SPHL mating deck above. The main chamber is fitted out with BIBS and Bunks for 15 men (12 Divers) and is equipped with medical facilities. The SPHL mating trunk descends directly into the TUP end of the chamber. Main Chamber Specifications Manufacture LSWE Engineering Serial No LSWE/U/11/01 Year Built 2011 Depth Rating 200 MSW Capacity 15 men living compartment Volume 30.8 CU.MTR Internal Diameter 2094mm View Ports 3 x View port 140mm 3 x View port 250mm BIBs 16 x connections with 16 x overboard dump type bibs Communications 2 x Sound powered phone (1 at medical bunk). 2 x Speaker talk & call units (1 at med bunk). 2 x Internally mounted CCTV with Monitors in LSC panels Scrubbers / CCU 6 x 24v scrubbers 15 x emergency lung powered scrubbers 3 x CCU-7 Lights 6 x overhead lights and 15 x bunk lights Medical Lock 1 x Medical Lock (330mm ID) Fittings Table & seats in seating area Trunk DDC to SPHL trunk complete manual clamp and safety interlock Fire Extinguishers 2 x Fire Extinguisher

5 TUP The TUP chamber is a separate pressure vessel connected to the end of the main chamber by a bolted flange type manway. It is designed and fitted out with BIBS for 3 men. The TUP also acts as the systems wet pot for ablutions and is fitted with a large equipment lock. TUP Specifications Manufacture LSWE Engineering Serial No LSWE/U/11/02 Year Built 2011 Depth Rating 200 MSW Capacity 3 man compartment Volume 5.9 CU.MTR Internal Diameter 2094mm View Ports 2 x View port 140mm BIBs 4 x connections with 4 x overboard dump type bibs Communications 1 x Sound powered phone direct to Sat Control 1 x Speaker talk back and call unit direct to Sat Control 1 x Internally mounted CCTV with monitor in Sat Control at chamber control panel Scrubbers / CCU 1 x 24v scrubber 1 x CCU-6 Lights 2 x overhead lights Equipment Lock 1 x Equipment Lock (610 mm ID) *interchanges with HRC trunk Sanitary Fittings Hyperbaric toilet with interlock device SS sink and shower head Trunk TUP to HRC trunk complete with manual clamp and safety interlock (interchanges with equipment lock) Fire Extinguishers 1 x Fire Extinguisher Note: TUP to HRC Trunk (Lower Skid) The trunk can be mounted at either side of the TUP allowing for different configuration of the system if required. The equipment lock will always be fitted to the opposite side of the HRC trunk.

6 HRU Mating 1. HRC Alignment Skid The HRC has a dedicated alignment skid that will be positioned under the HRC allowing for alignment of the HRC to the TUP trunk. Each corner of the HRC alignment skid is fitted with adjustable jacking bolts allowing for the HRC alignment frame to be raised or lowered. There are also four cone pads supplied to be located under the jacking bolts to assist with the raising and lowering of the HRC. 2. SPHL Hydraulic Alignment On the upper skid there is a hydraulic alignment system for the mating of the SPHL onto the HRF which is controlled by with four levers mounted on the alignment control panel. The control console also houses an air driven hydraulic pump which supplies the hydraulic power to the alignment system. 3. SPHL Hydraulic Alignment Support Cradles The upper level of the HRF is fitted with a hydraulic alignment support cradle for the mating of the SPHL onto the HRF complex which consists of two independent support cradles. There are two stainless steel guides on the bottom of the SPHL that locate into the support cradles, each support cradle is fitted with 2 off 25 ton hydraulic double acting rams at each end of the support cradles. The hydraulic rams are operated by the hydraulic control console which can raise or lower the support cradles giving faster alignment of trunks than a conventional manual jacking system. Each support cradle is fitted with six 36mm diameter securing bolts that are used to secure the cradles once the alignments of the trunks are completed. Flow control valves are fitted so fine control of the double acting hydraulic rams can be achieved during lowering the SPHL onto the DDC to SPHL trunk.
