The EES shall be connected to the saturation system and pressurized to the shallower storage depth as a minimum, during all diving or decompression operations. 9. The EES shall be connected to the saturation system and a reserve supply of gas shall be available to press the EES to the deepest storage depth of the system during all diving or decompression operations. This procedure should be detailed in the emergency procedures for evacuation (see number 8). Section 8.0 VESSELS AND FLOATING PLATFORMS FOR DIVING OPERATIONS Section 8.2 LIVE BOATING Added definition: Live Boating is a diving technique where a single surface-supplied diver performs work underwater while his hose is being tended from the bow of a vessel which is manually operated by the vessel master and underway using its main propulsion system. Added ADDITIONAL CONSIDERATIONS: Due to the inherent risks of live boating operations, all other means of diving operations should be considered if possible. If live boating has been determined to be the method of diving to be executed, these additional considerations should be taken into account to ensure safe operations: Performance of a thorough risk assessment Performance of drills for diver recovery, loss of breathing media to the diver, and to test the vessel s emergency shutdown device Depending on the vessel, shaft rotation indicators, propeller guards, and other barriers or mechanical devices to prevent the diver and standby diver s umbilical from coming into contact with the
vessel s propellers should be considered for utilization An assessment of work to be performed, water depth, and the communications available on the vessel should factor into the manning levels of the crew Ensure that the dive supervisor has a clear line of sight of the diver s umbilical entering the water and diver s bubbles Ensure that there are direct communications between the captain, diving supervisor, standby diver, and tender Section 8.2.1 MINIMUM REQUIREMENTS 1. Depth Limits The maximum depth limit for live boating operations is 170 fsw (51 m). Removed: Depth limits for live boating Section 8.3.9 SURFACE-SUPPLIED DIVING FROM DYNAMICALLY POSITIONED VESSELS 1. Minimum Personnel One air or mixed-gas diving supervisor (NOT part of the dive rotation). One manifold operator Two divers One standby diver Three tender/divers One air or mixed-gas diving supervisor (NOT part of the dive rotation) One manifold operator (when mixed-gas [HeO₂] diving) One diver One standby diver Two tender/divers Two LARS/Winch Operators 8.3.9.1 Surface-oriented Diving Surface diving off a DP vessel requires: Open-bottom bell with emergency onboard gas. Diver/tender at depth. Bell umbilical management and surface umbilical management plan (should be Surface diving off of a DP vessel requires: Open-bottom bell with emergency onboard gas. (For air or nitrox dives, a stage with emergency on-board gas may be substituted for an open-bottom bell.) A tending point on the surface or in-water
filed with JHA). Both divers to have access to surface and on-board gas. All umbilicals must be tethered to the main bell wire or secondary lift wire. from which the diver s umbilical can be securely tended. Tending can be achieved safely by employing: o a tender located on the vessel; o a tender located in a stage above the surface; o an unmanned in-water tending point (e.g. open-bottom bell, diver s hoop); o an in-water tender Bell umbilical management and surface umbilical management plan (should be filed with JHA) Diver (and if utilized, in-water tender) to have access to surface and on-board gas. All umbilicals must be tethered to the main bell wire or secondary lift wire The following requirements for surface diving operations are in effect only when the vessel is operating in the DP mode. DP mode is defined as whenever there is any form of motive power in operations, e.g., thrusters or propellers. The following requirements for surface and saturation diving operations conducted from a vessel are in effect only when the vessel is operating in the DP mode. DP mode is defined as whenever there is any form of motive power in operation, e.g., thrusters or propellers, which automatically maintains its position (fixed or a pre-determined track) by means of thruster force. The DP system consists of a power system, a thruster system, a DP-control system with the redundancy built in to maintain or restore its function, e.g. DP II or DP III. Diving operations conducted from a DP II of DP III vessel should not be considered Live Boating and may be performed at any time during the day or night, provided a thorough hazard assessment has been performed. Main and Standby Umbilical Lengths 1. Main umbilical must be 20 feet shorter 2. Standby umbilical must be 10 feet shorter 1. Main umbilical must be 16 feet shorter 2. Standby umbilical must be 10 feet shorter
