22.1.7.2 Demobilization of equipment
Once the mission is completed, ensure the equipment is packaged adequately for travel from the work location. Upon return to the base, perform the following steps to demobilize the equipment for storage:
• Ensure all system functions are performing and operational.
• Verify that the system is completely free of salt water. If there is any presence of saltwater
residue, rinse completely with fresh water and dry before storing.
• Perform preventative maintenance in accordance with manufacturer-specified guidelines.
• Ensure all O-rings, seals, joints, and turn points are greased and packaged for storage.
• Store in accordance with manufacturer’s recommendations.
22.2 Servicing and troubleshooting
All ROV systems share the same basic operating characteristics and maintenance needs. This sec- tion contains an outline of troubleshooting and preventative maintenance that should be performed on a regular basis. These procedures are not a substitution for manufacturers’ suggested operating and maintenance procedures. These are guidelines to supplement manufacturer-specific instructions. A major source for this section is Wernli (1998).
22.2.1 Maintenance
Equipment maintenance forms a vital part of a safe and efficient ROV operation. Properly main- tained systems can achieve substantially reduced downtime. System schedules ranging from simple predive checklists through detailed planned maintenance procedures must therefore be used to attain and maintain the highest possible standard of operating efficiency.
All work should be undertaken in compliance with supplier’s/manufacturer’s recommendations. Each ROV system type is provided with a full set of vehicle manuals and vendor subsystem techni- cal information to enable efficient maintenance and reordering of system spare parts.
ROV system maintenance is divided into the following main areas of documentation:
• Operations and maintenance manuals and drawings
• Supplier manuals and drawings
• Catalogs of equipment
The above includes the following key subsections:
• Vehicle maintenance procedures
• Subsystem maintenance procedures, that is, video cameras, sonar system, tools/motors
• Detailed repair and maintenance procedures (found in the specific ROV operations manual)
All equipment shall be suitably labeled to indicate its operational status on arrival at the deploy- ment base in accordance with company procedures.
Every manufacturer of ROV equipment has a set of maintenance standards peculiar to their respective equipment. It is the responsibility of the ROV maintenance supervisor to assure that the
