2.1.1 The following plans and information regarding the hold ventilation systems and the electrical supplies to container plug-in points are to be submitted in triplicate for appraisal before construction is commenced:

1. Plans of ventilation arrangements:

   • Location and installation details of each hold space ventilation system showing duct arrangement and sizes.
   • Details of all mechanical ventilation fans including locations, number, duty at design conditions and power consumption.
   • Details of air inlets including number, type, size and locations.
   • Details of air outlets including number, type, size and locations.
   • Details and locations of dampers and flaps, if applicable.

2. Plans of hold spaces:

   • Design pressure or vacuum in each hold space.
   • Details of hatch cover sealing arrangements.
   • Personnel access arrangements.
   • Details and locations of hold temperature measurement sensors.
   • Details of any pressure/vacuum safety valves if applicable.

3. Ventilation throughput:

   • Specified air throughput rate and proposed method of measurement.
   • Design temperature rise in the hold space and corresponding diurnal external ambient air temperature and relative humidity.
   • Schematic arrangement of the ventilation system showing proposed air volume and velocity at junctions.

4. Plans of deck-stowed containers:

   • Refrigerated container stowage plans, including sectional elevation and plan views.
   • Details of access arrangements for maintenance and monitoring of refrigeration units fitted to deck-stowed containers.

5. Hull structure:

   • Details of associated openings through the hull structure are to be submitted.

6. Electrical. In addition to the applicable requirements of Pt 6, Ch 2, 1.2 Documentation required for design review, the following information and plans specific to the container plug-in points and ventilation system are to be submitted:

   • Power supply arrangements to the deck stowed refrigerated containers.
   • Power supply arrangements to the hold space stowed refrigerated containers.
   • Power supply arrangements to the ventilation system.
   • Single-line diagram of the ventilation system. This is to include rating of motors, insulation type, size and current loading of cables and make, type and rating of protective devices.
   • A schedule of normal operating loads of the ventilation system estimated for the design conditions expected.

7. Control equipment. In addition to the applicable requirements of Pt 6, Ch 1, 1.2 Documentation required for design review , the following information and plans specific to the ventilation system are to be submitted:

   • Line diagram of control circuits.
   • List of monitored, control and alarm points.
   • Locations of control panels and consoles.
   • Details of alarm system, including location of control panel and audible and visual warning devices.

8. Testing:

   • Details of the testing and commissioning programme, including instrumentation to be used, are to be submitted.
