10. Special operational conditions
Liveboating means diving from a vessel that is moving under power (propellers are engaged while divers are in the water).
Liveboating presents severe hazards to the diver and must be avoided as far as is practicable.
Liveboating from a surface vessel shall not be conducted at night or in rough seas or from vessels with insufficient manoeuverability. Controls that will prevent the diving umbilical or tether from becoming entangled in the propellers shall be employed.
The tender for a liveboating operation shall be competent to perform this type of tending. The tender shall be in direct voice contact with the diving supervisor.
When liveboating is necessary and the divers use Scuba, the use of a lifeline may be more hazardous than alternative arrangements.
