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 MF90 installation trunk must be noted on the vessel’s docking plan
for future reference.
Make sure that ample clearance under the MF90 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 MF90 installation trunk.
Important
Prior to dry docking, turn off the MF90 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 MF90 system.

paying for such approval.

local area network (LAN). When you connect a computer to a local area network you will
always expose the data on that computer. All other computers connected to the same
network may be able to access your data. Several threats may immediately occur:
