Some centrifugal cargo oil pumps are designed with an automatic stripping system, which allows the cargo oil tank to fully discharge its contents. By what principle does such a stripping system operate?
On the basis that, if cargo vapour can be stopped from entering the cargo pump suction inlet, the flow will continue without cavitation.
By automatically reducing the rate at which oil cargo enters the cargo pump, such that any vapour lifted along with the liquid does not cause a loss of suction.
By the optimum size and positioning of the suction inlet that feeds the automatic stripping system, which ensures that the cargo oil tank is discharged to the maximum possible extent.
On the principle that if the suction is fitted low enough in the cargo oil tank and a specified minimum trim is maintained, suction will be available until the tank is completely discharged.

Large slow speed diesel engines are usually of the crosshead type and have various arrangements to deliver lubricating oil directly to the crosshead bearings and guides to ensure adequate lubrication. Why are the crosshead bearings considered differently to the other bearing in this type of engine in respect of lubrication requirements?
The lubricating oil has further to travel to the crosshead bearing and so a separate arrangement is necessary
The crosshead bearing is more heavily loaded than other bearings in the engine so requires more oil to keep it cool.
The crosshead bearing is closer to the engine cylinder and therefore runs hotter.
The running surfaces oscillate relative to each other during operation rather than rotate and therefore full film hydrodynamic lubrication is not possible.
