5. Total system
ROV including its control, launching, recovery, working and supply systems.
6. Maximum diving depth
A maximum diving depth where the ROV's can be operated safety is measured from ROV's bottom to the surface water.
7. Maximum permissible diving pressure
A maximum permissible diving pressure is under maximum diving depth.
8. Umbilical
Kink between the supporting ship and the ROV which can contain monitoring, communications and power supply cables as well as tether
9. Garage
Cage in which the ROV can be launched and recovered, e.g. from the surface vessel, and from which the ROV can travel under water to the work site.
10. Clamping devices

In case
: For ROVs built under the supervision of the Society.
: For ROVs considered to be fit as the result of surveys by the Surveyor after construction
of an application of ROVs control station or Launching and recovery system, the notation
may be added.
2. When ROV's systems and their parts thereof whose new development is based on other principle, the relevant rules shall be applied.
104. Certification
ROV's which comply with the requirement of the Rules and have been built under the Surveyor to the Society will be issued an appropriate certificate.
105. Maintenance of registration
1. Periodical Surveys on installations or equipment registered by the Society to maintain their registra- tion are to comply with the requirements specified by the Society.
