Q

On offshore drilling units, each fire station is required to be fitted with a hose which has a nominal diameter of __________.

🔍 Key Concepts

• 46 CFR requirements for fire hoses on mobile offshore drilling units (MODUs) • Typical fire main hose diameters used on commercial vessels and offshore units • Why a standardized hose size is important for nozzles, couplings, and pump capacity

💭 Think About

• Think about what hose sizes are commonly used with standard fire nozzles and hydrant fittings on ships and offshore units. • Consider which option lists sizes that are realistic for handling by a small crew in an emergency on a moving platform. • Eliminate any sizes that would likely be too large to handle safely, or too small to deliver enough water for offshore fire-fighting.

✅ Before You Answer

• Verify in 46 CFR Part 108 (Fire protection for MODUs) what hose diameters are specified for fire stations. • Check which listed sizes match typical marine fire hose standards used with 1-1/2 inch and 2-1/2 inch nozzles. • Confirm that the selected answer provides a pair of commonly used standard sizes, not extreme or unusual diameters.
