"3.7.2. The hold or interbarrier spaces of Type
A independent tank ships should be provided with a drainage system
suitable for handling liquid cargo in the event of cargo tank leakage
or rupture. Such arrangements should provide for the return of any
cargo leakage to the liquid cargo piping. Such a system should be
provided with removable spool pieces."

by the following:
"3.7.4 Ballast spaces, including wet duct keels
used as ballast piping, fuel-oil tanks and gas-safe spaces may be
connected to pumps in the machinery spaces. Dry duct keels with ballast
piping passing through, may be connected to pumps in the machinery
spaces, provided the connections are led directly to the pumps and
the discharge from the pumps lead directly overboard with no valves
or manifolds in either line which could connect the line from the
duct keel to lines serving gas-safe spaces. Pump vents should not
be open to machinery spaces."
