launch/recovery of the WFSV in 2.5m Hs an d higher sea states. Due to the proximity of the wet deck to the waves in high sea states, an initial proposal was to launch the Mainprize M002 using a retracttable cantilever frame and as shown in Figure 22. A schematic representation of the lifting frame andwinch plan is shown in Figure 23.

Living and working in the same space requires a formal demarcation between activities, even though people continue to work in fourth spaces. This is achieved by locating the briefing room and changing room in the lower decks. This means that the lower stairwell has to communicate the design me aning of a transition between the formal work areas and the accommodation areas of the vessel. The briefing room is essential for face-to-face communication before a 12 hour maintenance shift and afterwards for communication as a TPM activity. The changing area shown in Figures 20 and 21 is designed as a personal space with storage of work ware and storage for personal ittems, to help the user develop an affin with the space . The use of simulated environment views engages in biophilia. Given the loading time of WFSV the changing provision is for half the total crew, usiing domotic technology to identify crew members enables the changing room as a space to be shared by two crew members at different times with security control on the lockers, to make it a personalised space. The inclusion of video conferencing technology to allow technicians to make a brief connection with friends or family before starting work will keep them socially connected.

A key aspect of launch/recoverry of the WFSV in high sea state is the need to constrain the motion of the vessel which the lifting frame is brought into cont act with the hull to prevent damage. To facilitate this a fendered bollard is required for the WFSV to drive ont constrain the vessel motion. These would

tubes attached to the horizontal tube shown in Figure 22. Where the horizontal bar is in the process of being lowered below the waterline. This proposed solution operates as follows:
When the transfer vessel iis ready to be lifted the bollard beam is lowered. This gives the transfer vessels a surface to drive against at parti al throttle to restrict the relative motion and make the lifting points easier to locate.
After the beams have been lowered the will be deployed 22.5m from the rear
lifting beam garage. The
lifting cradles will be lowered to the water level and further lowered until theiirr highest po int is 5.5m
