Detailed Guide: GSK MCQ Set 6 Topics for Exit Exam
Welcome to the in-depth study guide for GSK MCQ Set 6. If you are preparing for your GP Rating Exit Exam or the CCMC online test, solving MCQs is only half the battle. To truly pass with high marks and perform well during your onboard training, you must understand the reasoning behind every answer.
This set covers critical areas of General Ship Knowledge (GSK) including mooring safety, cargo handling terminologies, Rules of the Road (ROR), and emergency procedures. Below, we break down the most confusing topics from Set 6 to help you master them for both your written and oral examinations.
1. Cargo Handling: Angle of Repose
One of the most frequently asked questions in GSK Set 6 is about the "Angle of Repose." In simple terms, this applies specifically to bulk cargoes (like coal, grain, or iron ore). It is the maximum angle of the slope at which loose solid material will remain in place without sliding.
Why is this important for a cadet? If a ship rolls in rough weather and the cargo shifts because the angle of repose was exceeded, the ship can capsize. Remember, for general cargoes like bales, pallets, or sacks, this term is not used. It is strictly for dry bulk.
2. Mooring Safety and Snap-Back Zones
Mooring operations are among the most dangerous tasks on a ship. In Set 6, we discuss the "Forward Spring." The main purpose of a spring line is to prevent the ship from moving forward or aft along the jetty. Specifically, a Forward Spring prevents the vessel from moving Ahead.
Another critical safety concept is the "Snap-Back Zone." When a mooring rope is under tension, it stretches. If it breaks, it snaps back with lethal force. Crew members must never stand in the bight of a rope or directly behind a tensioned wire. Always stand clear and communicate effectively with the bridge.
3. Enclosed Space Entry Procedures
A question in this set asks about the "Enclosed Entry Permit." This is a mandatory requirement before entering spaces like cargo holds (when loaded), ballast tanks, or the chain locker. These spaces may lack oxygen or contain toxic gases.
- Ventilation: The space must be ventilated for at least 24 hours (or as per company SMS).
- Testing: The atmosphere must be tested for Oxygen (21%), Hydrocarbons (0% LEL), and Toxic gases (like CO and H2S).
- Permit: The Master or Chief Officer must sign the permit before anyone enters.
4. Understanding Draft Marks
As a deck crew member, reading draft marks is a daily duty in port. The draft marks on the ship's hull indicate the depth of the ship underwater. In the metric system, draft marks are usually 10 cm high, and the gap between them is also 10 cm. The question in Set 6 often confuses students regarding how many places draft marks are painted. They are typically found in 6 places: Forward (Port/Stbd), Midship (Port/Stbd), and Aft (Port/Stbd).
5. Rules of the Road (ROR) and Lights
Navigation safety relies heavily on lights and shapes. In this quiz, we cover the "Masthead Light." This is a white light placed over the fore and aft centerline of the vessel. It has an uninterrupted arc of visibility of 225 degrees (112.5 degrees on either side of the bow). Understanding these angles is crucial for the lookout watch.
Additionally, sound signals in restricted visibility (fog) are tested. A power-driven vessel that is "underway but stopped and making no way" sounds two prolonged blasts at intervals of not more than 2 minutes. If the ship is moving (making way), it sounds one prolonged blast.
6. Life Saving Appliances (LSA)
SOLAS (Safety of Life at Sea) dictates the requirements for LSA. One key takeaway from Set 6 is regarding "Rocket Parachute Flares." A lifeboat must carry 4 rocket parachute flares. These are used for long-range distress signaling and can reach a height of 300 meters. Do not confuse this with the bridge requirement (12 flares) or the life raft requirement.
7. Shipboard Maintenance and Housekeeping
Good housekeeping is not just about cleanliness; it is about safety. Loose gear, oily rags, or cluttered alleyways can lead to accidents, injury, and fire. For example, ropes must be stored in a dry, well-ventilated space away from chemicals and direct sunlight to prevent rotting (especially natural fiber ropes) or UV degradation (synthetic ropes).
Conclusion and Next Steps
GSK MCQ Set 6 challenges your knowledge on a wide variety of topics. By consistently scoring above 90% in these mock tests, you ensure a smooth passing experience in your DG Shipping final exams.
