The manoeuvring system being a system and not a control is approached differently.
If an owner requires the servicing of an existing hydraulic – pneumatic system instead of upgrading it with a new electronic one:
- Disassembles all elements of the system from the vessel
- Services each element separately and checks it for proper operation
- Reassembles the elements on the vessel
- Adjusts the system to its original condition
- Commissions it
It must however be stated that more than once the cost of such a procedure is such that it is to the advantage of the owner to substitute the existing system with a new, electronic one at a reasonable surcharge.
