ABS recommends five interim actions pending any formal modification. Which of the following is NOT one of ABS's five recommendations?

A. Immediately retrofit an alarm and interlock to every bypass-capable valve without requiring any formal design review

B. Conduct an onboard review by the crew evaluating all possible bypass scenarios, including ballasting/deballasting by gravity

C. Lock the ballast water inlet and discharge valves and place them under the control of a designated responsible person

D. Post clear warning signage stating ballast water discharge is prohibited unless it passes through the BWMS

A. The piping arrangement may permit the ballast water management system to be bypassed during ballast uptake and discharge operations without activating an alarm

B. BWMS units are failing to achieve the required treatment efficacy under testing

C. Crew are not trained to operate the BWMS control panel

D. Ballast water record books are not being completed in the correct language

A. It must be connected to the BWMS so that any bypass activates an alarm, and the bypass event must be recorded both by the control/monitoring equipment and in the Ballast Water Record Book

B. It must be sealed shut and require a class surveyor's authorisation to open under any circumstances

C. It may bypass the system silently provided the Master verbally informs the Chief Engineer

D. It is only required to be logged if used more than once per voyage
