Dry docking requirements
Whenever a hull unit and an installation trunk are mounted under the vessel’s hull, special considerations must be made prior to dry docking.
The location of the ST90 installation trunk must be noted on the vessel’s docking plan for future reference.
Make sure that ample clearance under the ST90 installation trunk and/or blister is provided when you are placing the vessel in dry dock. Avoid locating supporting blocks or structures in the vicinity of the ST90 installation trunk.
Important
Prior to dry docking, turn off the ST90 system. If necessary, disengage the circuit breaker. Label the Processor Unit and/or the circuit breaker clearly to prevent anyone from accidentally turning on the ST90 system.
