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.
Make sure that ample clearance under the SC90 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 SC90 installation trunk.
Prior to dry docking, power down the SC90. Disengage the circuit breaker if necessary.
Label the Processor Unit and/or the circuit breaker clearly to prevent anyone from
powering up the SC90 accidentally.
Note
The location of the SC90 installation trunk must be noted on the vessel’s docking plan
for future reference.
Requirement for classification approval
Classification approval is required for the SC90 installation.
The SC90 sonar trunk installation must be approved by DNV GL or another national
classification society. The shipowner and shipyard performing the installation are
responsible for obtaining the classification approval.
Network security
If a SC90 system is connected to a local area network, data security is important.
Equipment manufactured by Kongsberg Maritime is frequently connected to the vessel's
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:
• Remote computers can read the data.
• Remote computers can change the data.
• Remote computers can change the behaviour of the computer, for example by
installing unwanted software.
Usually, two parameters are used to define the threat level:
1 The likelihood that any remote connection will do any of the above.
2 The damage done if a remote connection succeeds doing this.
Kongsberg Maritime has no information regarding the complete system installation on
any vessel. Systems provided by Kongsberg Maritime are regarded as stand-alone offline
