Question 3391 Deck General

The correct answer is A) When it is being towed to a new location. Under the International Rules of the Road, a jack-up drilling rig would be considered "underway" when it is being towed to a new location. This is because the rig is in motion and not fixed in position, even though it may not be actively engaged in drilling operations. The other options are incorrect because: B) the rig is stationary and elevated when taking on preload, C) the rig is moored and not in motion, and D) the rig is stationary and engaged in drilling, which does not constitute being "underway" under the Rules of the Road.
