A tanker in ballast, having recently left the discharge port is involved in a collision. The two vessels are still interlocked after the collision and a survey of the ships gives all crew members are safe and the damage is focussed to the vicinity of the impact. What should be the greatest concern at this time?
When the two vessels separate, one (or both) of the vessels will have insufficient stability to remain afloat.
The possibility of pollution.
The ships moving together in the swell/seaway will cause a spark and consequently an explosion.
The vessels moving together will create even greater damage to their structures.
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?
By Rule 18, a power-driven vessel underway shall keep out of the way of a sailing vessel. I will maintain my course and speed, but will continue to monitor situation to ensure the other vessel takes avoiding action.
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.

The current test includes Seagull CES questions on the topic of «Deck, Management, Oil Tanker». These questions are designed to assess the competence of specialists in preventing accidents related to transport safety and can also be used for self-assessment.
The «Management» subject provides both theoretical and practical knowledge essential for advanced training on any type of vessel. Proficiency in this area is a direct indicator of an employee's competence in their specific role on a vessel. On an oil tanker, the Deck Management Officer is responsible for a wide range of duties that ensure the vessel's safe operation and compliance with international standards, including command, navigation, and cargo management. The specific responsibilities for deck management on an oil tanker can vary depending on company policies, as well as international regulations and standards governing maritime safety and operations at sea.
