Kewatec RESCUE 1500: A Hybrid Boat Built for Firefighting and Rescue

The Kewatec RESCUE 1500, inspired by the e-FiFi 1470 design, is a hybrid firefighting and rescue vessel equipped with MOLABO’s advanced 48-volt electric drive technology. Recently delivered to the City of Kiel Fire Department in Germany, this vessel will serve critical roles in firefighting, rescue operations, disaster response, and civil protection along the Kiel Canal, Kiel Fjord, and up to 6.2 miles (10 kilometers) offshore.

Specifications and Design:

• Overall Length: 52.7 feet (16.05 meters)

• Hull Length: 48.1 feet (14.67 meters)

• Waterline Length: 44 feet (13.4 meters)

• Beam: 15.7 feet (4.79 meters)

• Displacement: 52,692 pounds (23.9 tons) light, 56,218 pounds (25.5 tons) fully loaded

Power and Propulsion:

The RESCUE 1500 is built with a hybrid propulsion system that allows for both electric and diesel-powered operation:

• Diesel Engines: Twin Volvo Penta D13-700 engines, each providing 690 horsepower (515 kW) at 2,250 rpm for robust performance during extended missions and demanding conditions.

• Electric Motors: Dual MOLABO Aries i50 motors, rated at 67 horsepower (50 kW) each, run on MOLABO’s 48-volt technology, driving Doen DJ172-HE waterjet systems for safer operation and simpler maintenance by avoiding high-voltage systems.

Performance Modes:

Electric Mode: Silent and emission-free, ideal for low-noise missions. The vessel can reach up to 6.8 knots and sustain speeds of 6 knots (6.9 mph) for up to two hours.

Diesel Mode: Optimized for extended missions or harsh weather, allowing speeds up to 36 mph (31.3 knots).

Boost Mode: Combines electric and diesel power, adding up to 4 mph (3.5 knots) to the top diesel speed, reaching 38.6 mph (33.5 knots) for rapid response needs.

Safety and Efficiency:

The RESCUE 1500’s Doen DJ172-HE waterjet propulsion reduces in-water hazards, as there are no exposed propellers, making it safer for rescue operations. MOLABO's "safe-to-touch" 48-volt electric drive minimizes maintenance needs and reduces CO₂ emissions and operational costs, supporting sustainable, low-impact missions.

Statement from MOLABO:

Adrian Patzak, COO of MOLABO GmbH, emphasizes that the RESCUE 1500's advanced, safe, and eco-friendly propulsion empowers Kiel firefighters with cutting-edge technology to protect local waters and coastlines effectively.
