🔍 Key Concepts

• 46 CFR Subchapter M requirements for towing vessel fire protection • Specific minimum flow rates for fixed fire pumps on towing vessels • How construction date (01/2017) affects which regulatory standards apply

💭 Think About

• Which Subchapter M section covers fixed fire pumps on towing vessels, and what minimum capacity does it specify? • Does the regulation give the pump capacity per nozzle, per hose, or as a total pump output, and how does that affect your choice? • How does the vessel’s construction date (after Subchapter M implementation) influence whether older, smaller-capacity standards could apply?

✅ Before You Answer

• Verify the exact gpm figure stated in 46 CFR for a self-priming fixed fire pump on towing vessels. • Confirm that the required capacity is for continuous output at a specific pressure (usually 50 psi at the highest outlet). • Make sure you are using the standard for newly constructed towing vessels, not grandfathered vessels built before Subchapter M dates.
