30 MCQs #1 You have determined the maneuvering characteristics of your vessel by taking radar ranges and bearings of an isolated light while making a turn. The results are shown in illustration D035DG below. What is the transfer for a turn of 90°? #2 You are stopped with no way upon your vessel at the pilot station. Your vessel is a large twin-screw ship. You must come around 180° to board your Pilot. How should you use the engines and rudder to turn the ship fastest in the least amount of space? #3 The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). Although winds are less than 70 knots, excessive motion requires ballasting to survival draft. Assume that 4087 long tons of ballast are added at an average VCG of 8.32 feet, and upon arrival at 45 feet, port and starboard ballast tanks 1, 3, and 8 are slack. What will be the new margin on the maximum allowable KG? #4 To what distance below the hull must the legs of the COASTAL DRILLER be lowered in order to meet the stability and leg strength requirements during the wind speeds greater than 70 knots? #5 On the DEEP DRILLER, among the starboard-side valves to open when deballasting from ballast tank 8S is valve __________. #6 What is the maximum weight that can be placed in the setback area on the COASTAL DRILLER? #7 Among the equipment included in the DEEP DRILLER lightweight are the loading hoses, derrick, traveling block in the lowest position, anchors, all machinery with liquids to normal operating level, and __________. #8 If the charted water depth is 200 feet, the limits of service for the COASTAL DRILLER require an air gap of __________. #9 Preloading tests the soil to the vertical leg reaction that would be imposed by __________. #10 The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). According to the deck load graph, how much additional deck load could be added on the unit? #11 Under ideal conditions, the DEEP DRILLER can pick up and place pipe in the rack at a rate of about __________. #12 A mat-type jack-up drilling unit is the best selection for __________. #13 The COASTAL DRILLER is loaded as shown in the Sample Load Form #1 (Rig Move). While in field transit, the wind speeds are predicted to increase above 70 knots. What would be the change in KGL if the legs are lowered to the recommended value? #14 The DEEP DRILLER is loaded as shown in Sample Load Form #5 (Survival). While the unit is deballasting, port valve 5 fails in the closed position. You may deballast from tank 2P by pumping from tank 1P after opening valves 6 and __________. #15 While elevated, the COASTAL DRILLER prepares for a severe storm. When the setback is lowered and placed in the pipe racks, it is considered as part of the __________. #16 The COASTAL DRILLER, with a draft of 10 feet 3 inches in seawater, has a displacement of __________. #17 The DEEP DRILLER, at 58.0 feet draft in sea water, places 200 long tons on board. What is the new draft? #18 If the maximum amount of weight is stored in the pipe racks of the DEEP DRILLER, what is the weight per square foot? #19 When elevating the COASTAL DRILLER in 200 feet of water, the unit should be placed at an air gap of __________. #20 Adding the longitudinal free surface correction to the uncorrected height of the center of gravity of a MODU yields __________. #21 You are operating a liftboat. Before starting jacking operations you should __________. #22 What is the maximum weight permitted on the cantilever pipe racks for the COASTAL DRILLER? #23 When the COASTAL DRILLER is elevated, the water for the saltwater eductor system is provided by __________. #24 In storm conditions, with the wind and waves from the starboard bow of the DEEP DRILLER in 600 feet water depth, the offset is 8%. Completely slacking mooring lines 7 and 8 reduces the offset to __________. #25 The Cantilever Beam Load Chart for the COASTAL DRILLER shows the load limits in the hook, setback, conductor tension, and __________. #26 What maximum wind velocity is assumed when determining the limits of elevated service for the COASTAL DRILLER? #27 The DEEP DRILLER is operating at a draft of 60 feet. There is 11.5 feet of drill water in each of the drill water tanks (5P and 5S). What would be the improvement in KGL if 5S is filled from 5P? #28 The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). How much additional deck load can be placed aboard without exceeding the deck load limit? #29 Because of the presence of 75 knot winds, the DEEP DRILLER is at survival draft. KGL is 1.24 feet less than the maximum allowed. What is the value of GML? #30 When preloading the COASTAL DRILLER, the minimum total weight shall not be less than __________.
