Leave the blank flanges off, but hang a label over each line that will not be required, stating "not to be used this port".
Leave the lines open, but tie-off (or otherwise secure) the manifold valves so that they can not be operated by accident.
Leave the lines open to prevent condensation building up inside.
The best way to prevent stowaways from boarding your ship is to:

Inert gas drawn from an in-line unit in the main or auxiliary boiler exhaust cannot normally be used in a chemical tanker carrying high-spec products. Why is this?
Because MARPOL severely restricts the cleaning to sea of tanks that have been inerted in this way, unless additional prewashing has first been carried out. This results in the generation of slops which reduce cargo carrying capacity and incurs disposal costs.
Because the gas drawn from such a source cannot be guaranteed to be below the Lower Explosive Limit.
Because the levels of hydrocarbons and suspended soot particles will have a significant negative impact on cargo quality and tank cleanliness.
Because connection between boiler exhaust systems and cargo containment arrangements is forbidden under the IBC Code.

Some main propulsion medium speed engine installations operate with a hydraulic oil type fluid coupling between the engine and the reduction gearbox instead of a mechanical clutch. With this type of installation a separate flexible coupling is not normally fitted. Why is a separate flexible coupling usually omitted from this type of installation?
There is insufficient room to fit a flexible coupling between the engine and gearbox when a fluid coupling is fitted.
There are no engine torque variations in the drive when a fluid coupling is used so a flexible coupling is not required.
The hydraulic fluid in the coupling isolates the gearbox from the engine vibrations.
There is natural slippage between the drive and driven parts of the fluid coupling and a flexible coupling would prevent this slippage.

Why are all passenger ships divided into vertical ’zones’?
Vertical zones are separated with fire doors which will be closed automatically when the fire alarm start.
All vertical zones are separated with watertight doors, which will be closed in the case of a grounding, etc.
Vertical zones are fire zones which can be divided from each other with fire doors. In case of fire, all fire doors in front and aft of the fire will be closed to prevent spreading of smoke/fire.
There is one fire team in each zone.
How might a leak from a cargo tank on an oil tanker be readily detected during the voyage?
By regularly monitoring the vessel's trim on the cargo computer - any cargo that leaks will run to the end of a compartment, resulting in an increase in trim.
By occasionally opening a selected tank and manually measuring the cargo ullage, then comparing it to the 'after loading' reading.
By regularly monitoring void and ballast spaces, such as by testing them for hydrocarbon content and sounding them.
By frequently monitoring cargo level equipment readouts and comparing them to the load port departure readings.
