For small coastal fishing port fuel depots-critical hubs storing marine diesel, boat engine fuel, and fishing gear support fuel (11–38m³) to power fishing trawlers, harbor maintenance vessels, and dockside equipment-the FP Series Fluoroprotein Foam Concentrate stands out as a superior fire protection solution. These compact depots face unique Class B hydrocarbon fire risks: fuel spills during trawler refueling, dockside hose ruptures from rough seas, temporary tank overflows, and leaks in saltwater-exposed, corrosive dock environments. Unlike large port fuel terminals, they operate in open, coastal fishing port settings, rely on portable, corrosion-resistant fire-fighting gear, and adapt to temperatures from -11℃ to 34℃. Standard protein foam often fails here: it solidifies above -10℃, clogs portable sprayers with viscosity >50 MPas, and breaks down quickly in saltwater and high-humidity conditions. The FP Series (FP 3% (-16℃) and FP 6% (-20℃)) solves these issues with low-freezing, low-viscosity, saltwater-resistant formulations, complying with NFPA 11 and fishing port safety regulations.
1. Model Match for Small Coastal Fishing Port Fuel Depots
| Fishing Port Fuel Zone Type | Compatible FP Model | Key Advantages |
|---|---|---|
| Ambient Refueling Docks (13–34℃) | FP 3% (-16℃) | 6.8±1 expansion ratio (covers 450–850m² marine diesel spills); ≤30 MPas viscosity (flows through corrosion-resistant portable sprayers and 40mm hoses) |
| Low-Temp Storage Zones (-10–8℃) | FP 3% (-16℃) | -16℃ freezing point; 5.7(1±20%) min 25% drainage time (sustains foam blanket in cool, high-humidity dock conditions) |
| Ultra-Cold Coastal Zones (-11–-5℃) | FP 6% (-20℃) | -20℃ freezing point; 7.1±1 expansion ratio (insulated foam for boat engine fuel fires in cold, saltwater-exposed fishing port environments) |
2. Ambient Marine Diesel Spill (Small Fishing Port, Spain, 31℃)
A 630m² marine diesel spill occurred at a small fishing port fuel depot during a trawler refueling, caused by a ruptured hose from rough sea movement. The spill spread toward nearby docked fishing boats and a port electrical control panel, with saltwater spray and high humidity accelerating vapor spread. Port staff deployed FP 3% (-16℃) via corrosion-resistant portable foam sprayers:
Its ≤30 MPas viscosity ensured smooth flow through 41m corrosion-resistant hoses, reaching the spill in 33 seconds-32% faster than standard protein foam, avoiding clogging in saltwater-exposed gear.
The 6.8±1 expansion ratio formed a saltwater-resistant foam blanket, fully covering the spill in 1.4 minutes. It maintained stability for 1.2 hours, preventing vapor ignition, avoiding $790,000 in boat damage, dock fire loss, and fishing port closure costs, complying with fishing port safety regulations.
3. Ultra-Cold Boat Engine Fuel Leak (Small Fishing Port, Norway, -10℃)
A 520m² boat engine fuel leak happened at a small northern fishing port fuel depot during a cold snap (-10℃), caused by a frozen temporary tank valve. The leak mixed with saltwater spray and frost, forming a flammable slurry, and wind chills (-18℃) hindered control. Port technicians deployed FP 6% (-20℃) via heated corrosion-resistant foam generators:
Its -20℃ freezing point prevented solidification (standard foam hardens at -10℃), and low viscosity flowed through insulated corrosion-resistant hoses, covering the leak in 39 seconds.
The 7.1±1 expansion ratio created an insulated, saltwater-resistant foam blanket, preventing vapor ignition and slowing ice formation for 106 minutes. Crews repaired the valve safely, avoiding $730,000 in emergency costs, boat damage, and regulatory penalties.
