Novel Concepts

KNUD E. HANSEN A/S looks forward to the challenges that our clients bring to us, however unusual they may be. Our combination of naval architecture and marine engineering skills gives us the capability to devise practical and efficient solutions.

SWORC – Shallow Water Oil Recovery Catamaran

As a small catamaran, it can be quickly disassembled on its trailer and stored in a 20 feet standard container for protection and easy long-distance transport. The SWORC employs a unique bagging system that allows the oil to be collected in a sealable bag which when full can be dropped between the hulls of the vessel for later collection. The result is an uninterrupted skimming solution that can be quickly and precisely deployed.

With help from KNUD E. HANSEN A/S, the Danish clean-tech company Poseidon Floating Power is developing a floating power plant. A 37m prototype was deployed in 2008 which uses a combination of wind turbines and wave energy converters to generate electricity.

The platform is semi-submersible and held in place by a turret mooring system. Each individual wave energy converter is a stand-alone module which can be easily replaced for scheduled maintenance. Its design ensures that the water behind the wave energy converters is relatively calm, significantly reducing the problem of getting access to floating wind turbines in higher sea states.

Fuel Saving Solutions

KNUD E. HANSEN A/S is a keen advocate of the trimaran concept as an effective route to reduced fuel consumption for large, fast Ro-Pax ferries and in 2004 we undertook a proof-of-concept study for such a vessel. Counter rotating podded propellers were also specified for even greater propulsion efficiency.


Concept For Stena


In fact, fuel saving technologies have been a focus area for KNUD E. HANSEN A/S for over two decades.  In the mid-1990s we proposed a solution that involved fitting wing masts on slow, large vessels like bulk carriers and tankers. By suspending fiberglass panels in horizontal shafts through a central steel mast we made it possible to shift an asymmetrical high-lift profile from starboard to port when tacking through the wind.
