Q

How much drill water is required for transfer between drill water tanks 25 and 26 in order to correct the list of the COASTAL DRILLER with total transverse moments of -6,800 ft-kips?

🔍 Key Concepts

• Transverse moment and how moving weight athwartships changes it • Relationship between weight moved, distance moved, and resulting moment (W × d) • Direction of list correction when moving weight from one side (tank 25) to the other (tank 26)

💭 Think About

• First, decide which side must gain weight and which must lose weight to correct a negative total transverse moment of -6,800 ft-kips. Which tank is on which side? • Write the basic equation for correcting list: how much new moment do you need to add (and in what direction) to bring the total transverse moment to zero? • Use the distance between the centers of tanks 25 and 26 to relate the needed change in moment to the amount of weight moved.

✅ Before You Answer

• Check the sign convention: does moving water from tank 25 to 26 create a positive or negative transverse moment? • Compute the moment change as W × distance; be sure you’re using the distance between tank centers, not from centerline to only one tank, unless specified. • Verify that the new total transverse moment after transfer (initial + change) is approximately zero, indicating the list is corrected.
