A qualified person shall be designated as the diving supervisor for each diving operation. The diving upervisor is in charge of the planning and execution of the diving operation, including responsibility for the safety and health of the dive team.
The diving supervisor shall posses the proper PTRD supervisor certification card and be knowledgeable and familiar with all techniques, procedures, emergency procedures and operational parameters for the diving mode under his or her direct supervision.
In carrying out these responsibilities, the diving supervisor’s duties shall include, but not necessarily be limited to, the following:
• Be fully cognizant of all relevant governmental regulatory agency regulations that apply to the diving operation and the diving mode employed and the employer’s basic safe practices/pperations manual. See that all rules and regulations are followed.
• Have adequate knowledge, training and familiarization with all life-support and ancillary equipment designated to the diving operations.
• While actually on duty, be in immediate control and available to implement emergency procedures.
• Ensure diving operations are carried out from a suitable and safe location on the surface.
• Develop or modify and produce pre- and post-dive checklists for the operation.
• Develop and implement emergency/contingency procedures.

• Be aware of the procedures to follow to obtain medical support in the event of an accident, either diving or non-diving related. Ensure a two-way communication system is available at the dive location to obtain emergency assistance.
• Perform a Job Safety Analysis for each task undertaken.
• Establish a dive plan ensuring that sufficient breathing mixtures, supplies and proper equipment are available for safe and timely completion of the job task.
• Assign the duties of all members of the dive team and personally direct them throughout the diving operation.
• Personally verify that all personnel on the dive team are qualified and physically able to perform tasks assigned. He or she must make an assessment of the physical condition of the divers prior to each dive to determine if any physical impairment is present that would be detrimental to the divers’ health and safety in the water or under hyperbaric conditions.
• Ensure that the diving equipment designated for use is:
– Suitable for the planned diving operation.
– Sufficient to regulatory requirements for the diving mode used.
– Inspected prior to each dive and is in good working order.
• Ensure that all relevant operating instructions, manuals, decompression tables, treatment schedules and regulatory publications are available at the dive location and are maintained to reflect current changes and/or developments.
• Ensure the detailed briefing of his or her diving team and support personnel, including:
– Tasks to be undertaken.
– Unusual hazards or environmental conditions.
• Make modifications to standard procedures or safety procedures necessitated by the specific diving operation.
• Maintain a depth, bottom time and breathing mix profile at the dive location for each diver during the dive.
• Ensure that each diver is continuously tended while in the water.
• Ensure the dive is terminated when:
– The diver requests termination.
– The diver fails to respond to communication or communication is lost between the diver and dive team members at the dive location.
– Communication is lost between the vessel operator and the diving supervisor during liveboating operations.
– The diver begins to use his or her diver-carried reserve breathing gas supply.
– Weather or site conditions are degrading to the extent that diver safety may be compromised.
• Ensure after every dive:
– The physical condition and wellbeing of the diver is checked by visual observation and verbal questioning.
– The diver is instructed to report any physical problems or symptoms of decompression sickness or arterial gas embolism.
– The diver is advised of the location of the nearest operating decompression chamber and is acquainted with the dangers of flying after diving or traveling to altitudes higher than the dive site.
• Ensure after any treatment or dive outside the no-decompression limits:
– The diver is instructed to remain awake and in the vicinity of a decompression chamber for at least one hour.
– A trained dive team member is available to operate the decompression chamber.
• Report all accidents or incidents involving personnel as required by employer’s rules and relevant governmental regulations.
• View and ensure accuracy of diver’s personal log book and affix signature to properly record activities.
• Ensure prior to each bell run:
– All bell checks are performed, internally and externally, and recorded.
– All pertinent vessel or facility operators are properly notified.
– All support equipment and personnel are prepared for the operation.
– Clear communications are established with vessel operators, Dynamic Position operators(DP), Remotely Operated Vehicle  operators (ROV), crane operators and any other pertinent operational personnel.

• Ensure the bell run is terminated when:
– Vessel is unable to or in danger of losing station keeping ability (weather or mechanical failure).
– There is loss of hot water, gas, primary electrical power or any other life-support equipment
– The atmosphere in the bell cannot be controlled (e.g., buildup of CO2).
– Weather, sea or external conditions endangering the bell.
– There is loss of clear communication with critical operation personnel such as the DP vessel operator on a DP diving vessel.
– There is loss of the DP alert system on a DP vessel.
– The DP officer issues a yellow or red light on a DP vessel.
– There is danger to topside crew preventing or degrading the performance of bell retrieval operations such as an approaching weather front or lightning.
– Primary communication with the bell is lost.
– There is a suspected or confirmed presence of hydrocarbon gas in the bell.
– Any time that the safety and wellbeing of the saturation divers warrants termination.
• Ensure after each bell run:
– Any maintenance or repairs are performed to bring all redundant systems back on line.
– Perform proper record keeping relative to LARS (Launch And Recovery Systems) performance and upcoming maintenance issues.
– Debrief deck crew regarding any issues encountered during bell recovery.
– The deck foreman, LST (Life Support Technician) and sat techs are fully aware of any maintenance or repair issues and preparations are being made to be ready for the next bell run.

• Successful completion of the PTRD supervisor exam.
• PTRD supervisor certification card for the diving mode.
• Before being exposed to hyperbaric conditions, the supervisor must be medically certified as “fit to dive.”
• Valid CPR and first aid certification.
