Question 3796 Deck General

The correct answer is C) twelve months. On a Mobile Offshore Drilling Unit (MODU), the regulations require that all firefighting equipment must be inspected and serviced at least once every twelve months. This requirement is specified in 46 CFR 109.527, which governs the inspection and testing of firefighting equipment on MODUs. The other answer choices are incorrect because they do not align with the regulatory requirement of annual (12-month) inspections. Inspections every 3 months, 6 months, or 18 months would not be compliant with the applicable Coast Guard regulations for firefighting equipment on a MODU.
