is accomplished in order to enhance team synergies. A proper crew briefing should include the fol- lowing essential elements:
• Mission tasking and/or threat outline, detailing the specific requirements of the task
• A thorough and complete explanation of the job components
• A scope of work and specific goals to be accomplished during the task
• Ingress/egress routes to the work site
• Crew positions during the task as well as specific responsibilities
• Tactics, techniques, and procedures for accomplishing each individual task as well as
completion of the mission
• Specific information needed as well as methods of documentation
• All relevant information on the object of inspection, including (but not limited to) drawings,
maintenance records, damage reports, survivor statements, and any other information that would
assist in the work task
• Work site coordinates
• Topographical maps, bathymetry data, tide tables, underwater obstruction analysis, prior
surveys, and any other environmental information that will assist in accessing the work site
• If there was any prior work done on the work site, it is imperative to thoroughly review this
information (and, if possible, interview the previous crew) and job reports to better gain an
insight into the current site condition
• Schedule for completion of the task objectives (best case/worst case/most likely case) with
consideration given for field delays
• A thorough detail (and, if deemed necessary, drill) on emergency procedures
The ROV supervisor should also take further steps to be fully briefed on any other conditions that would affect or interfere with his planned operations, including (but not limited to):
• Planned vessel movements
• Vessel/platform support operations (including support vessel logistics)
• Diving operations
• Drilling operations
• Pipeline lay operations
• Operation of surface and subsurface machinery
• Scheduled power generation equipment outages/changeovers
Many industrial applications for ROV operations require a job safety analysis (JSA) to be performed and condensed into writing in order to document the job-specific hazards and steps for mitigating those hazards.
22.1.4.2 Vehicle preparation
The sequence of events from crew briefing to the contact of the vehicle with the water should be conducted in a logical and fluid flow. Once the briefing is completed, the predive checklist is begun and continued until the vehicle is in the water. If there is a checklist item that is unable to be cleared, the supervisor’s judgment will dictate if the items will stop the predive sequence. If a long interval is encountered between the completion of the predive checklist and the start of the actual
