Modern medium speed diesel engines normally have relatively short crankshafts with large diameter pins. How do these design features affect the reliability of crankshaft deflection readings?
The design of the crankshaft has very little effect on the readings when compared to the inaccuracies that arise due to human error.
Very short, stiff crankshafts do not deflect even when the engine is running so the readings are unaffected.
They increase the risk of inaccurate readings due to the 'stiff' shaft having very small natural sag which may therefore result in 'floating journals' in the static condition.
They reduce the risk of inaccurate readings as the large diameter pins result in a relatively heavy shaft which will reduce the risk of 'floating journals'.

Only a drip tray is required.
A full secondary barrier is required.
On a RoRo vessel, why should there be no more than two lashings secured to any one point on a ro-ro unit?

Earlier cellular reefer vessels were constructed with a 'porthole system' for supplying refrigerated air via ducting to containers. Modern vessels are designed to supply only electrical power to integral containers. Select the main reason for this change in design to the vessels and containers from the options given.
A large amount of refrigerant gas was required to operate the 'porthole' system.
The introduction of more powerful diesel engines onto these vessels meant they had sufficient electrical capacity to supply the integral type containers.
