  1. 1. Figure 1* *James Fisher Submersible Rescue Vehicle (LR5).
  2. 2. Figure 2 Submersible rescue vehicle (LR5) connected to the TUP compartment and portable, one-man RCC. James Fisher Defence refers to its TUP compartment as the Universal Deck Reception Chamber.
  3. 3. Figure 3 PDCS (%, y-axis) in rescue personnel for single dives with bottom times from 60280 minutes (x-axis) at 253 kPa estimated using the NMRI-98 model. At each bottom time the cluster of bars gives the PDCS for decompression according to each table that has a schedule for that bottom time. The order in the bar cluster is always the same DCIEM 2 (blue); XVALSS_DISSUB 7 (green); VVAL-18M (orange); Royal Navy 14 (Modified) (red) but not all bars may appear. For instance, the VVAL-18M table does not have an entry for 75-minutes bottom time and consequently there is no orange bar in the cluster at this value of the x-axis. 0 1 2 3 4 5 6 7 60 75 80 90 100 110 115 120 130 140 150 160 170 180 190 200 210 220 230 240 250 260 270 280 PROBABILITYOFDCS% DIVE PROFILE (MINUTES) PDCS FOR SINGLE DIVES 60 - 280 MINUNTES @ 253 kPa (NMRI-98 MODELLING) DCIEM 2 XVALSS_DISSUB 7 VVAL-18M ROYAL NAVY 14 (MODIFIED)

  7. 7. Figure 7 Total Decompression Time. Minutes (y-axis) in rescue personnel for single dives with bottom times from 75460 minutes (x-axis) at 253 kPa. At each bottom time the cluster of bars gives the TDT for decompression according to each table that has a schedule for that bottom time. The order in the bar cluster is always the same DCIEM 2 (blue); XVAL SS_DISSUB 7 (green); VVAL-18M (orange); Royal Navy 14 (Modified) (red) but not all bars may appear. For instance, the VVAL-18M table does not have an entry for 75-minutes bottom time and consequently there is no orange bar in the cluster at this value of the x-axis. 0 50 100 150 200 250 300 75 85 90 95 100 110 120 125 130 135 140 150 160 170 180 190 200 210 220 230 240 250 260 270 280 290 300 310 320 330 340 350 360 370 380 390 400 410 420 430 440 450 460 MINUTES BOTTOM TIME (MINUTES) TOTAL DECOMPRESSION TIME (253 kPa)DCIEM 2 XVALSS_DISSUB 7 VVAL-18M ROYAL NAVY 14 (MODIFIED)
