The Twin Fin solution is simple; it uses well-proven technology arranged in a flexible way offering the following advantages: Increased thrust and efficiency Twin Fin gives higher thrust and requires lower input power. Thanks to the large size of the propellers, they run at low shaft speed through a very short shaft line with minimal mechanical loss. Reduced maintenance and easy access for service The compartment is easily accessible from inside the hull for inspection and service. No need to dry dock in case of repairs The gear and electric motor(s) as well as the stern tube inner sealing can be exchanged through the deck rendering it ideal for remote areas like the Arctic. Increased reliability and flexibility Components and techniques are well proven in the harshest environments and can be tailored to any vessel due to the flexibility in the design and positioning of the fins. Reduced fuel consumption and green concept Hydrodynamically-designed fins ensure homogenous water flow to the propellers resulting in lower fuel consumption, lower emissions and reduction of noise. Increased cargo space and deadweight With the engines placed in the fins rather than in the hull, there is extra cargo space, buoyancy and therefore extra deadweight. . Well proven for safety in the Arctic The design is comparable to single-screw vessels that have proven extremely reliable even in the harshest environments. The fins protect the propulsion system and can also be fitted with ice knives. Easy to retrofit with very short yard stay Pre-fabricated, fully-equipped fins tailored specifically to the vessel render the retrofit simple and ultrafast. 4
