Question 2394 Deck Safety

The correct answer is A) 60 tons. The explanation is as follows: 1. The question states that you have 420 tons of below deck tonnage and 180 tons of above deck cargo. When you load 140 tons of liquid mud below deck, this reduces the available below deck tonnage to 420 - 140 = 280 tons. The remaining above deck cargo capacity is 180 tons, so the maximum additional deck cargo you can load is 180 - 120 = 60 tons. 2. This is based on the standard regulations for vessel stability and load calculations, which require careful accounting of the vessel's total cargo capacity, both below and above deck, to ensure the vessel remains stable and seaworthy. 3. The other options are incorrect because they exceed the remaining above deck cargo capacity based on the given information.
