70% to pass

Prior to getting underway in fresh or brackish water, the Master or person in charge of a MODU must _______________.

A take on fresh water ballast
B log the density of the water
C secure all overboard discharges
D clean the sides with fresh water
AI Explanation

The correct answer is B) log the density of the water. Prior to getting underway in fresh or brackish water, the Master or person in charge of a MODU (Mobile Offshore Drilling Unit) must log the density of the water. This is a regulatory requirement to ensure the stability and safe operation of the MODU. Knowing the water density is crucial for accurately calculating the MODU's draft and maintaining proper ballast conditions. The other options are incorrect because: A) taking on fresh water ballast is not a mandatory requirement, C) securing overboard discharges is a general safety practice, not specific to this situation, and D) cleaning the sides with fresh water is not a regulatory requirement before getting underway.
