30 MCQs #1 While in transit at a draft of 20.5 feet, the DEEP DRILLER has a KGL of 65.00 feet. What is the GML? #2 The DEEP DRILLER is operating with KGL at the maximum allowable value (70 knots) at a 60 feet draft. What is the value of GML? #3 What is the minimum required GML for the DEEP DRILLER in winds less than 70 knots while at a draft of 60 feet? #4 What are the maximum vertical moments, including free surface moments, permitted on the DEEP DRILLER at survival draft if the winds are greater than 70 knots? #5 What are the maximum vertical moments including free surface moments permitted on the DEEP DRILLER at a draft of 60 feet if the winds are greater than 70 knots? #6 What are the maximum vertical moments, including free surface moments, permitted on the DEEP DRILLER at a draft of 60 feet if the winds are less than 70 knots? #7 The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). What is the new height of the center of gravity corrected for transverse free surface effects if the entire contents of Salt Water Ballast Tanks 1P and 1S are discharged? #8 An icebreaker assisting a vessel through an ice field would display a visual signal consisting of the code letter "E" (Echo) to signify that "__________". #9 A twin-screw vessel with a single rudder is making headway. The engines are full speed ahead. There is no wind or current. Which statement is FALSE? #10 The rotary of the COASTAL DRILLER is located 34 feet aft of the transom and 2 feet to port of the centerline. With the changes to lightweight shown in the Operating Manual, the maximum allowable hook load is __________. #11 While drilling loaded as shown in Sample Load Form #4 (Drilling), the DEEP DRILLER suffers a sudden unexpected inclination to port and aft. Strong winds and high waves are from the starboard bow. Among the possible causes, you should consider __________. #12 During an ocean tow when the winds are less than 70 knots, the maximum allowable KG for the COASTAL DRILLER is __________. #13 What is the change in the vertical moments (excluding free surface effects) for the COASTAL DRILLER if 2.0 feet of drill water is transferred from a full drill water tank 23 to an empty drill water tank 6? #14 In towing it is desirable for the tug and the MODU to ride wave crests simultaneously because __________. #15 The maximum load line draft for the COASTAL DRILLER is __________. #16 What is the maximum permitted hook load for the COASTAL DRILLER when 450 kips are in the setback and no other loads are on the cantilever? #17 The COASTAL DRILLER is loaded as shown in the Sample Load Form Number 1 (Rig Move). If the drill water in drill water tanks 6 and 25 are discharged, what is the new draft? #18 The COASTAL DRILLER is loaded as shown in the Sample Load Form Number 1 (Rig Move). If the contents of the four bulk tanks are back-loaded to a supply boat, what would be the new draft? #19 An elevated jack-up weighs 14,000 kips. Its TCG is located 1.0 foot to port of the centerline. What would be the new TCG for the jack-up if the drill floor, weighing 700 kips, is skidded 10 feet to starboard? #20 A jack-up displacing 350,000 cubic feet while floating in sea water (64 pounds per cubic foot) weighs __________. #21 While in ocean transit, the COASTAL DRILLER has a roll period of four seconds. What would be the largest angle each side of vertical that does not exceed the design limit of the legs? #22 Forces within a drilling unit have caused a difference between the starboard and port drafts. This difference is __________. #23 Curve A in the Design Limits of Legs Chart of the Coastal Driller Operating Manual, shows the operating limits during severe storm conditions during transit based on __________. #24 While loaded as shown in the COASTAL DRILLER sample load form 3 (drilling), all of the casing is discharged. What is the change in LCG? #25 The proximity of pack ice may be indicated by __________. #26 The COASTAL DRILLER, in transit with winds less than 70 knots, has a draft of 10 feet 8 inches. The VM are 541,257 ft-kips, FSML are 32,000 ft-kips, and FSMT are 24,000 ft-kips. The margin on the maximum allowable KG is __________. #27 While in 150 feet water depth when the pitch angle of the COASTAL DRILLER is 2 degrees, the platform roll period for going on location should be longer than __________. #28 On the COASTAL DRILLER, the level of water in each of two pump bilge pits is monitored by hydrostatic alarm switches connected to a remote panel located in the __________. #29 Because there is a possibility of fuel oil being discharged overboard from a full fuel oil tank, it is decided to transfer 25 kips from tank 14 to tank 13. See COASTAL DRILLER Sample Load Form Number 1 (Rig Move). What would be the change in longitudinal free surface moments? #30 For a floating MODU, true mean draft is always the __________.
