(25) Laundry, including ironing room, etc.
50 m2 + 0.07 m2 per person of complement

(26) Air conditioning fun rooms
2.5% of total ventilated volume.

(27) Lining andflure
3.4% total ventilated volume (1)-(25).

(28)-(30) Cargo spuces
As specified. Convert to moulded volume by dividing by following constants.
Grain: 0.98
Bale: 0.88
Refrig: 0.72.

(31)-(32) Oil fuel, diesel oil
Calculate for the required endurance at specific consumption rates corresponding
to the engines selected. Allow for port consumption and for a margin remaining on
arrival at bunkering port. Allow for fuel used for heating, distillation and hotel
service purposes.
(33) FresWfeed water
With distillation or osmosis plants now generally fitted, fresh and feed water
storage capacity is arranged to provide storage to suit the emergency which would
result from a breakdown and this obviously depends on the voyage route.
(34) Wuter ballast
Only tanks with no other use need be considered. Provision must be made for the
tanks required to maintain stability in the burnt-out arrival condition, plus any
tanks needed to provide flexibility of trim to cope with all loading conditions.
Generally, water ballast capacity should be between 2/3 and 3/4 of the sum of the
oil fuel, diesel oil and fresh water consumption.

(35) Cofferdams, pipe tunnels
15% of volume of (31)-(34).

(36) Solid ballast
If it is intended to fit this, the necessary stowage space should be allowed.

(37) Refrigeration stores
Allow 0.04 m3 per person per day of voyage and convert to gross volume by
dividing by 0.72.
