30 MCQs #1 The DEEP DRILLER is loaded as shown in the Sample Load Form #4 (Drilling). According to the deck load graph, how much additional deck load could be added on the unit? #2 You should consider placing the drilling operations of the DEEP DRILLER in standby when __________. #3 The DEEP DRILLER is loaded as shown in Sample Load Form #4, (Drilling). In preparing for approaching heavy weather, the four leeward mooring lines are slacked. These actions reduce the __________. #4 For a semisubmersible moored in heavy weather conditions, the weather lines should be adjusted so that several lines carry about the same tension, and the leeward lines are __________. #5 When clear ice is present while drilling, the vertical transverse moments of the DEEP DRILLER are increased by __________. #6 In storm conditions, when the DEEP DRILLER is in 600 feet water depth, and the high-line tension (HLT) is 350 kips, completely slacking the two leeward mooring line tensions reduces the HLT to __________. #7 In storm conditions, with the wind and waves from the starboard bow of the DEEP DRILLER in 400 feet water depth, the offset is 7%. Completely slacking mooring lines 7 and 8 reduces the offset to __________. #8 In storm conditions in 600 feet of water, completely slacking the leeward mooring line of the DEEP DRILLER reduces the tension in that line to about __________. #9 In storm conditions, with the wind and waves from the port bow of the DEEP DRILLER in 400 feet water depth, the tensions in mooring lines 1 and 2 are 400 kips. Completely slacking the mooring lines 5 and 6 reduces the tension in mooring lines 1 and 2 to about __________. #10 In storm conditions, with the wind and waves from the port bow of the DEEP DRILLER in 600 feet water depth, the tensions in mooring line 1 and 2 are 400 kips. Completely slacking the mooring lines 5 and 6 reduces the tension in mooring lines 1 and 2 to about __________. #11 It is proposed to moor the DEEP DRILLER in 600 feet of water in a region in which the effective wind velocity could reach 80 knots, significant wave height could reach 30 feet, and the current could be 1.5 knots. If these conditions occurred at the same time from the bow, the environmental force due to the wind would be __________. #12 It is proposed to moor the DEEP DRILLER in 600 feet of water in a region in which the effective wind velocity could reach 80 knots, significant wave height could reach 30 feet, and the current could be 1.5 knots. If these conditions occurred at the same time from the beam, the total environmental force would be __________. #13 The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). If weather conditions make it necessary to ballast down to survival, how much ballast would be required? #14 In storm conditions, when the environmental conditions are such that the DEEP DRILLER has disconnected the marine riser, the two leeward mooring lines should be __________. #15 The DEEP DRILLER is engaged in wire line logging. You have 10,000 feet of drill pipe and bottom hole assembly in the set back. Marine weather forecasts are predicting weather with winds in excess of 70 knots. Your first step to prepare for the storm should be to __________. #16 During the passage of a severe storm, the DEEP DRILLER is at survival draft. Strong winds are blowing from the starboard. A careful load form calculation determined that, although the unit is level, the TCG is 2.0 feet to starboard. The value of the wind heeling moment is __________. #17 Before deballasting to survival draft in the event of predicted heavy weather, the DEEP DRILLER Operations Manual recommends that the mooring lines be slacked __________. #18 For the DEEP DRILLER, in deballasting to survival draft when threatened with heavy weather from 100 knot winds, a load form should be calculated to determine that __________. #19 The DEEP DRILLER is on location during a storm. Windward anchor tensions begin to exceed the test tensions. To reduce tensions while minimizing offset over the well, you should __________. #20 The principal action in changing from transit to survival draft in the event heavy weather threatens is __________. #21 In a severe storm while elevated, the drilling loads on the COASTAL DRILLER must be considered as __________. #22 During a severe storm while the COASTAL DRILLER is elevated, on board loads must be shifted so that the TCG is on the centerline and the LCG is __________. #23 The COASTAL DRILLER is loaded as shown in the Sample Load Form #1 (Rig Move). What is the margin on the maximum allowable KG if winds increase to greater than 70 knots, and the TOC is changed to the recommended value? #24 The COASTAL DRILLER is loaded as shown in the Sample Load Form #1 (Rig Move). How much more variable load in kips can be placed on the unit if winds remain less than 70 knots? #25 The COASTAL DRILLER is loaded as shown in the Sample Load Form #1 (Rig Move). How much more variable load in kips can be placed on the unit if winds increase to greater than 70 knots? #26 The COASTAL DRILLER is loaded as shown in the Sample Load Form #1 (Rig Move). What is the margin on the maximum allowable KG if winds remain less than 70 knots? #27 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 new KGL if the legs are lowered to the recommended value? #28 If a severe storm threatens the COASTAL DRILLER while elevated, the setback in the derrick should be lowered and placed in the pipe rack. Its weight should be accounted for as __________. #29 The maximum weight for the COASTAL DRILLER in severe storm conditions is __________. #30 A severe storm threatens the COASTAL DRILLER, and a decision is made to evacuate the unit. If practical, all non-essential personnel should be off the unit in advance of the storm's predicted arrival by __________.
