What do the small passenger vessel regulations require when installing a hydraulic accumulator or other unfired pressure vessel?

Correct Answer: Option A — It be installed to the satisfaction of the cognizant OCMI

Per 46 CFR 182.330, unfired pressure vessels must be installed to the satisfaction of the cognizant Officer in Charge, Marine Inspection (OCMI). This ensures that the installation meets safety standards for the specific vessel's service and configuration, prioritizing structural integrity and operational safety over generic pressure testing requirements.
