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.
