4.1 Operation manual
An operation manual should be supplied and should include a plan of the ventilation
system, showing fans, supply air and exhaust air openings and doors, ramps, hatches,
etc. The location of the control panel for the ro-ro cargo space ventilation system
should also be marked.
The plan should show the various options for operation of the ventilation system. It
should include details of the design air flow and of the estimated number of different
types of vehicles in the different ro-ro cargo spaces under various loading and
unloading conditions.
The plan should be periodically revised and/or supplemented on the basis of the
experience gained from the normal vehicle loading and unloading conditions. A number of
blank drawings should therefore be kept on board.
On the basis of such experience, it should also be possible to draw up guidelines for the
maximum number of vehicles that should be allowed to operate simultaneously.
Whenever possible, places which are sheltered from the air flow should be indicated on
the plans.
The operation manual should include guidance for the service and maintenance of the
systems.
4.2 Control panels
The control panels on the ship should be installed in a convenient location.
A plan of the ship's ro-ro cargo spaces, showing the location of fans and openings,
should be kept at the control panel. Each fan should be given an individual
designation.
Indications as to which fans should be used for a given ro-ro cargo space under various
loading conditions should also be on display at the control panel.
For safety reasons and to facilitate control of the ventilation system, the control panel
should include means of indicating which fans are running.
The individual control and indicator lights should be marked with the same designation as
the fans to which they relate.
As far as possible, indicator lights and controls for fans that normally operate
simultaneously should be located in groups. This will help to make the function of the
controls readily apparent and will therefore facilitate correct use of the controls.
Automatic control of the air quality control system should be indicated at the control
panel.
