Read the text before answering the question: “We do need old ships to enable us to meet the world’s transport needs, but they must be in a good condition. The shipping world would have serious problems if all the old tonnage was taken out of service or broken up today. The new building activities of recent years has given insufficient transport capacity to tolerate more ships being broken up. It has yet to happen, however. It is up to the industry to ensure that more of the poorest ships are scrapped.” What is the fundamental requirement relating to the older ships, which are still in service?
The older ships must be in good condition.
The older ships should be scrapped to make way for the new builds.

The current test features Seagull CES questions on the topic of «Deck, Management, LPG». These questions are designed to assess the competence of specialists who can help prevent accidents related to transportation safety and can also be used for self-assessment.
The «Management» section provides both theoretical and practical knowledge essential for advanced training on any type of vessel. This knowledge directly reflects the competence of employees holding relevant positions on LPG tankers. A seafarer working on an LPG tanker, particularly within the deck department at the management level, is responsible for overseeing and carrying out key maritime operations. This includes navigation, cargo management, and ensuring strict adherence to safety protocols. They play a vital role in the safe and efficient transportation of liquefied petroleum gas, managing deck operations to maintain vessel stability and compliance with industry standards.
- Version: 6.0.9.
- Test type: STCW.
- Department: Deck.
- Level: Management.
- Vessel type: Liquefied Petroleum Gas Tanker.
