Not less than 1 250 mm.
Not less than moulded breadth/5.

A tug is connected to the bow of a vessel. Will the force exerted by it be the same at any ahead speed?
No, on the bow the tug uses power to run with the vessel, which reduces the available power on the towline.
No, when the ahead speed of the ship increases the force exerted by the tug will also increase.
Yes, the force would normally be expected to be the same at any speed of the ship.
Week.
A cargo pumproom or other enclosed space which contains cargo handling equipment on a chemical tanker shall be fitted with a mechanical ventilation system, capable of being controlled from outside the space. What is the minimum number of atmosphere changes per hour, based on the total volume of the space, that such a system must deliver?
Not less than 10 charges per hour.
Not less than 30 charges per hour.
There is no specified minimum number of changes, provided it is running continuously throughout any cargo operation.
If the ventilation is permanent, it shall deliver at least 20 changes per hour; if it involves part recirculation, then it shall deliver at least 30 changes per hour.

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.

The subject «Deck Department, Management Level, Chemical Tanker» covers both theoretical and practical knowledge about safely working with electrical equipment, which is a key indicator of an employee's competence in their role aboard a vessel. As a Deck Officer on a Chemical Tanker, the role involves a variety of responsibilities related to deck management. The primary duty is to oversee and coordinate the safe and efficient loading, unloading, and transfer of chemical cargo. This requires a thorough understanding of the chemical properties, handling procedures, and stowage requirements for each type of cargo, as well as ensuring compliance with all relevant regulations and industry standards. Additionally, Deck Officers are responsible for the safe navigation of the vessel, which includes planning and executing the vessel's route, maintaining its position, and adhering to all navigation regulations. They are also tasked with watchkeeping, maintenance, and ensuring the overall safety and security of the vessel.
