ISGOTT draws attention to the risk of electrostatic potential in a mist produced by using oil and water mixture in Crude Oil Washing operations. How does the Guide recommend this is avoided?
If a slop tank is to be used to supply oil to drive a Crude Oil Washing operation in a cargo tank, then that slop tank must not have contained slops with a water content of more than 2%.

Crude Oil Washing, where the oil source is stored in a slop tank or other tank that has previously contained slops, should be avoided.
Before washing begins, any tank that is to be used as a source of oil for Crude Oil Washing should be partly discharged to remove any water that has settled out during the voyage. The discharge of a layer of at least 1 metreis necessary for this purpose.

A large vessel develops a sudden sheer when it stops moving through the water, having been steaming through a shallow water channel for several miles. The sheer may be strong and unexpected and is due to what reason?
The shallow water reduces the effectiveness of the rudder and when the vessel stops any applied rudder will become suddenly more effective.
The vessel stopping shifts the pivot point forward and creates a turning moment and results in the ship swinging towards the bank.

Earlier reefer vessels designed and built for liner trade usually had two or three tween decks approximately 2 to 2.5 metres in height and deep lower holds approximately 4 to 5 metres deep.

There is an almost universal use of standard height pallets.
It is easier to construct vessels with shallow decks.
The increased number of container vessels has reduced the tendency to carry general cargo outbound from Europe or North America to Australia and New Zealand on reefer vessels.
