30 MCQs #1 Weights added or discharged at the center of flotation on the COASTAL DRILLER while floating will change the __________. #2 The rotary of the COASTAL DRILLER is located 38 feet aft of transom and 6 feet to starboard of the centerline. With the changes to lightweight shown in the Operating Manual, the maximum allowable hook load is __________. #3 Considering the changes to lightweight shown in Section 5 of the COASTAL DRILLER Manual, with the rotary 36 feet aft of the transom and 4 feet to port of the centerline, and with 300 kips in the setback, the maximum hook load is limited to __________. #4 On the COASTAL DRILLER, placing the rotary 34 feet aft of the transom and two feet to starboard of the centerline, limits the maximum hook load to __________. #5 Considering the lightweight changes to the COASTAL DRILLER, what is the maximum permitted hook load permitted when 450 kips are in the setback and 200 kips are in the cantilever pipe rack? #6 On the COASTAL DRILLER, hook load includes the weight of the __________. #7 Drilling loads on the COASTAL DRILLER are the combined loads arising from conductor tension, rotary, hook, and __________. #8 The rotary of the COASTAL DRILLER is located 36 feet aft of the transom and 6 feet to starboard of the centerline. The hook load is 300 kips. Considering the changes to lightweight shown in the Operating Manual, the maximum amount of setback is __________. #9 When the COASTAL DRILLER is loaded as shown in the sample load form Number 3 (drilling), the hook load is placed in the pipe racks. What would be the new variable load? #10 While in ocean transit at a draft of 10 feet, the Coastal Driller has a maximum allowed KG of __________. #11 The COASTAL DRILLER, in ocean transit at a draft of 10 feet 6 inches with winds greater than 70 knots, has a KGT of 38.7 feet and a KGL of 38.2 feet. The margin on the maximum allowable KG is __________. #12 The COASTAL DRILLER, in field transit at a draft of 10 feet 0 inches with winds less than 70 knots, has a KGT of 39.0 feet and a KGL of 38.6 feet. The margin on the maximum allowable KG is __________. #13 The COASTAL DRILLER, in ocean transit at a draft of 10 feet 0 inches with winds greater than 70 knots, has a KGT of 39.0 feet and a KGL of 38.6 feet. The margin on the maximum allowable KG is __________. #14 While the COASTAL DRILLER is in transit at a draft of 10 feet 6 inches, a severe storm is predicted within 12 hours. VM are 541,257 ft-kips, FSML are 32,000 ft-kips and FSMT are 24,000 ft-kips. How much should the KGL be lowered to satisfy the maximum allowable KG criteria? #15 While the COASTAL DRILLER is in transit at a draft of 10 feet 6 inches, a severe storm is predicted within 12 hours. VM are 520,462 ft-kips, FSML are 26,000 ft-kips, and FSMT are 25,000 ft-kips. How much should the KG corrected for free surface effects be lowered to satisfy the maximum allowable KG criteria? #16 While the COASTAL DRILLER is in transit at a draft of 10 feet 6 inches, a severe storm is predicted within 12 hours. VM are 546,462 ft-kips, FSML are 18,000 ft-kips, and FSMT are 32,000 ft-kips. How much should the KG corrected for free surface effects be lowered to satisfy the maximum allowable KG criteria? #17 While the COASTAL DRILLER is in transit at a draft of 10 feet 6 inches, a severe storm is predicted within 12 hours. GMT is 98.89 feet. How much should the KG corrected for free surface effects be lowered to satisfy the maximum allowable KG criteria? #18 The COASTAL DRILLER is loaded as shown in Sample Load Form Number 3 (Rig Move). What would be the new sum of vertical moments for the liquid variables if the entire contents of tank 20 are transferred to tank 13? #19 The COASTAL DRILLER is loaded as shown in the Sample Load Form Number 1 (Rig Move). If the contents of 6 and 7 drill water tanks are discharged, what would be the new height of the longitudinal metacenter? #20 The COASTAL DRILLER is loaded as shown in the Sample Load Form Number 1 (Rig Move). If the contents of 6 and 7 drill water tanks are discharged, what is the new height of the center of gravity corrected for longitudinal free surface effects? #21 The COASTAL DRILLER is in transit loaded as shown in the Sample Load Form Number 1 (Rig Move). What would be the new KGT if, during the move, 170.9 kips of fuel oil is consumed from Diesel Oil Tanks 13 and 14? #22 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 transverse free surface moments? #23 The height of the metacenter above the keel will vary depending on the __________. #24 If the metacentric height is large, a floating MODU will __________. #25 If the metacentric height is small, a floating MODU will __________. #26 The natural rolling period of a drilling barge increases when __________. #27 The free surface corrections depend upon the dimensions of the surface of the free liquids and the __________. #28 A slow and easy motion of a MODU in a seaway is an indication of a __________. #29 On a semisubmersible drilling unit, increasing riser tension reduces __________. #30 In the COASTAL DRILLER, VCG is obtained from the sum of the vertical moments by __________.
