You are on a sailing vessel, underway in open water. This vessel is sighted on the starboard bow, on a steady bearing and the distance is closing. By the International Regulations for the Preventing Collisions at Sea, what action will you follow?
Risk of collision is deemed to exist and, as the other vessel is on a steady bearing on my starboard side, I will maintain my course and speed.
This vessel is clearly a power-driven vessel and I anticipate that the bearing will therefore close and she will pass ahead at a safe distance.
Risk of collision is deemed to exist and, as the other vessel is on a steady bearing on my starboard side, I am required to keep out of the way. I will make a broad alteration of course to starboard.

I don’t know.
Either in a vertical or horizontal separation: if the intervening decks are not resistant to fire and liquid, then only in a longitudinal separation is acceptable.

In different compartments or holds when stowed “under deck”. Provided an intervening deck is resistant to fire and liquid, a vertical separation may be accepted as equivalent. For “on deck” stowage, this segregation means a distance of at least 6 metres.
With an intervening compartment, being both a vertical and horizontal separation. Provided an intervening deck is resistant to liquid and fire, a vertical separation of 6 metres is acceptable.

The «Cargo Handling and Stowage, Management, Oil Tanker» subject provides both theoretical and practical knowledge on safely working with electrical equipment. Mastery of this material is a key indicator of an employee’s competence in their role aboard a vessel. Cargo handling and stowage on an oil tanker involve the processes of loading, unloading, and storing liquid cargo, such as crude oil or petroleum products. These operations require meticulous planning, strict adherence to safety protocols, and compliance with industry regulations to ensure the safe and efficient transportation of liquid cargo.
