30 MCQs #1 SOLAS requires a logbook entry for the operation of watertight door drills. Which of the following lists the frequency that these drills are required to be conducted for passenger vessels? #2 SOLAS requires that passenger vessels make an entry in the log book for all drills and inspections of watertight doors. What other information relevant to the watertight doors is required to be entered? #3 Vessels subject to SOLAS are required to keep watertight doors closed while the vessel is navigating. Which of the following is an exception to this requirement? #4 In accordance with SOLAS, which of the following best describes the obligation of the Master concerning cargo hold watertight doors? #5 Your vessel is preparing to enter port. What is the SOLAS requirement for opening of the vessel's cargo hold watertight doors in this situation? #6 SOLAS requires which of the following with regard to watertight doors in cargo spaces? #7 Which of the following best defines the term "chock"? #8 GM cannot be used as an indicator of stability at all angles of inclination because __________. #9 In small-angle stability, when external forces exist, the buoyant force is assumed to act vertically upwards through the center of buoyancy and through the __________. #10 You have completed stability calculations for your vessel prior to getting underway. Your vessel's GM is small but positive. Which of the following is true? #11 Your vessel is discharging containers from the main deck with the ship's cranes. Which of the following must be taken into account when calculating the center of gravity as the containers are discharged? #12 The static stability curve for a given vessel peaks at 34°. For this ship, the danger angle for a permanent list would be about __________. #13 The improper stowage of cargo has caused vessels to have a negative GM. How will a ship in this condition handle in the seaway? #14 Your Ro Ro vessel has just completed discharging the lower decks and is commencing discharging the upper levels. What would it indicate if the vessel were to suddenly develop a list? #15 A vessel can be termed as either tender of stiff in relation to its rolling period. Which of the following would cause a vessel to be tender? #16 The average rolling period of your ship puts it in the category of a "stiff ship". What effect can this condition have on the cargo carried onboard while underway? #17 Which of the following defines "Rolling Period"? #18 You are hoisting a heavy lift with the jumbo boom. Your vessel displaces 8560 T. The 45-ton weight is on the pier and its center is 65' to starboard of the centerline. The head of the boom is 95' above the base line and the center of gravity of the lift when stowed on deck will be 55' above the base line. As the jumbo boom takes the strain the ship lists to 5.5°. What is the GM with the cargo stowed? #19 You are hoisting a heavy lift with the jumbo boom. Your vessel displaces 5230 T. The 35-ton weight is on the pier and its center is 60' to starboard of the centerline. The head of the boom is 105' above the base line and the center of gravity of the lift when stowed on deck will be 42' above the base line. As the jumbo boom takes the strain the ship lists to 5°. What is the GM with the cargo stowed? #20 You are making a heavy lift with the jumbo boom. Your vessel displaces 8390 T. The 40 ton weight is on the pier and its center is 55' to starboard of the centerline. The head of the boom is 110' above the base line and the center of gravity of the lift when stowed on deck will be 45' above the base line. As the jumbo boom takes the strain the ship lists to 3.5°. What is the GM with the cargo stowed? #21 You are making a heavy lift with the jumbo boom. Your vessel displaces 8530 T. The 40-ton weight is on the pier and its center is 65' to starboard of the centerline. The head of the boom is 115' above the base line and the center of gravity of the lift when stowed on deck will be 50' above the base line. As the jumbo boom takes the strain the ship lists to 5°. What is the GM with the cargo stowed? #22 You are making a heavy lift with the jumbo boom. Your vessel displaces 7940 T. The 45-ton weight is on the pier and its center is 60' to starboard of the centerline. The head of the boom is 110' above the base line and the center of gravity of the lift when stowed on deck will be 50' above the base line. As the jumbo boom takes the strain the ship lists to 4.5°. What is the GM with the cargo stowed? #23 You are making a heavy lift with the jumbo boom. Your vessel displaces 18,000 T. The 50-ton weight is on the pier, and its center is 75 feet to starboard of the centerline. The head of the boom is 112 feet above the base line, and the center of gravity of the lift when stowed on deck will be 56 feet above the base line. As the jumbo boom takes the strain, the ship lists 3.5°. What is the GM when the cargo is stowed? #24 To check stability, a weight of 35 tons is lifted with the jumbo boom, whose head is 35 feet from the ship's centerline. The clinometer shows a list of 7.0° with the weight suspended. Displacement including the weight is 14,000 tons. What would the length of GM in this condition? #25 To check stability, a weight of 40 tons is lifted with the jumbo boom, whose head is 40 feet from the ship's centerline. The clinometer shows a list of 6.5° with the weight suspended. Displacement including weight is 16,000 tons. What would be the GM while in this condition? #26 To check stability, a weight of 10 tons is lifted with the jumbo boom whose head is 45 ft. from the ship's centerline. The clinometer show's a list of 5.0° with weight suspended. Displacement including the weight is 9,000 tons. What would be the GM in this condition? #27 In order to check your vessel's stability, a weight of 40 tons is lifted with the jumbo boom, the boom head being 50 feet from the ship's centerline. The clinometer is then carefully read and shows a list of 5°. The vessel's displacement is 8,000 tons including the suspended weight. What will be the metacentric height of the vessel at this time? #28 The SS AMERICAN MARINER is ready to sail with the load shown in table ST-0182 below. Use the white pages of The Stability Data Reference Book to determine the available GM. #29 The SS American Mariner is ready to sail with the load shown in Table ST-0183 below. Use the white pages of the Stability data Reference Book to determine the available GM. #30 Your vessel's drafts are: FWD 27'-06", AFT 28'-02"; and the KG is 23.1 feet. Use the selected stability curves in the blue pages of the Stability Data Reference Book to determine the righting arm at 60° inclination.
