SMP’s well established manufacturing and design teams have recognised the requirement of the next step to extended bottom times with air, nitrox and mixed gas diving with the ever increasing demands in the renewable, oil and gas sectors in the offshore industry.
SMP have developed a solution for a closed Bell TUP System which will be a unique one-off design available to interested parties. This system is configurable to client requirements on a short lead time.
The system provides a cost effective diving solution through increased bottom times for the diving teams. This provides the capability for the diving team to be working from a Schedule 6 type Bell whilst the second team will be in decompression after completing their bell diving operations.
This will mean continual productivity from the diving bell teams with less down time and smaller diving crews that would be utilised with normal air and nitrox diving.
The system utilises a minimum 4.5 m3 saturation diving bell which has the capability of bounce diving operations. This is critical to the utilisation of this system. The diving bell can be lowered to the seabed under atmospheric conditions. When the divers arrive at the work site the supervisors will have the capability to pressurise the diving bell equivalent to the work site depth which will allow the divers to exit the bell to proceed with their tasks. This can be a single diver or two diver lock out with a standby diver remaining in the bell.
On completion of the dive the divers will return to the diving bell where the doors will be sealed. At this stage the divers in the bell will start their decompression procedure. The bell will then be recovered to the surface with the divers continuing their decompression within this controlled atmosphere. The bell will be recovered by the handling system into the bell capture arrangement thereafter manipulated onto the bell handling trolley for mating to the divers transfer lock.
The above process allows for much greater productivity with diver’s bottom times, a more controlled and safer working environment and quicker and safer decompression procedures as opposed to the regularly used oxygen surface decompression procedure.
