The KMT is __________. #13 The COASTAL DRILLER, with a displacement of 13,553 kips, has a draft of __________. #14 When assuming the maximum ice weight accumulation on the DEEP DRILLER at survival draft, the vertical moments are increased by __________. #15 The COASTAL DRILLER is in transit at a draft of 10.5 feet. It discharges 216.43 kips of weight. What is the new draft? #16 While underway in a field move with the lower hulls awash, a semisubmersible has a maximum allowable KG of 63.69 feet; KMT is 65.12 and KML is 64.92. The KGT is 56.13 and KGL is 55.89. What is the margin on the maximum allowable KG? #17 The DEEP DRILLER's lightweight is the condition prior to loading __________. #18 The height of the longitudinal metacenter of the COASTAL DRILLER at a displacement of 13,810 kips is __________. #19 The COASTAL DRILLER is elevated to an air gap of 25 feet in 250 feet of water. The current is 2 knots and the waves are 30 feet. The maximum leg reaction is 6,120 kips. What is the maximum wind for drilling operations? #20 The height of the transverse metacenter of the COASTAL DRILLER at a displacement of 13,011 kips is __________. #21 The DEEP DRILLER is loaded as shown in the Sample Load Form #3 (Preparing to Drill). According to the deck load graph, how much additional deck load could be added to the unit? #22 The DEEP DRILLER as currently configured is limited to a maximum water depth of __________. #23 The longitudinal location of the center of flotation for the COASTAL DRILLER has a value of __________. #24 The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). Weather conditions make it necessary to ballast down to survival draft. It is decided to check the stability at the intermediate draft of 32 feet. If the added ballast has an average VCG of 9.03 feet, what is the new KG? #25 Subtracting the height of the center of gravity corrected for longitudinal free surface effects from the height of the longitudinal metacenter of a MODU yields __________. #26 Subtracting the height of the center of gravity corrected for transverse free surface effects from the height of the transverse metacenter of a MODU yields __________. #27 The DEEP DRILLER is loaded as shown in the Sample Load Form #1 (Transit). Additional deck load may be placed aboard. If the maximum permissible deck load were placed in the pipe racks at a VCG of 130 feet, the KG increases __________. #28 The COASTAL DRILLER, while drilling, has a total weight of 15,400 kips. The LCG is 120.00 feet AF0, and the TCG is -0.5 feet to port of the centerline. What is the bow leg reaction? #29 The DEEP DRILLER may remain at operating draft instead of deballasting to survival draft when __________. #30 Adding the transverse free surface correction to the uncorrected height of the center of gravity of a MODU yields __________.
