Question 4240 Deck General

The correct answer is A) tapering the upper guides and building up the teeth. During a long ocean tow, the clearance in the upper guide should be reduced to zero to restrain the leg and eliminate the impact loads from dynamic responses. This is best accomplished by tapering the upper guides and building up the teeth. This reduces the clearance between the leg and the guide, effectively restraining the leg and minimizing the impact loads that can occur from the leg's dynamic motion during the tow. The other options are incorrect because they do not directly address the need to reduce the clearance in the upper guide. Removing lengths of the leg, raising the spud cans into hull recesses, or lowering the spud cans below the hull do not specifically target the clearance issue in the upper guide.
