When handing over the con of a vessel to a pilot, should the Master insist in discussing the passage plan with the pilot while he is there to use his local knowledge and advice on the navigation of the ship?
A passage plan should be discussed between the Master and pilot, when under pilotage in the same way as discussed with the bridge team when deep sea.
A pilot is responsible for the navigation whilst on board and will be very familiar with what is required, therefore discussing the passage plan is not necessary.
The pilot would probably consider it unnecessary, be more interested in knowing the ship’s characteristics and resist any passage planning discussions with the Master.
The passage is well established and known by the pilot and a plan is therefore not necessary.
You are to carry a cargo of Phenol across the North Atlantic in winter time. What precaution will you take with the double bottom tank located under the cargo tank containing the Phenol?

It should be continuously vented to avoid the build up of condensation on the structure around the product.
It is not necessary to take any additional precautions with the double bottom tank because it is part of an entirely separate pumping system.
It should be inerted, because Phenol has a very low Flash Point.
