The suspension system reduces the risk during personnel transfer offshore or in pilot transfers significantly. The delivery platform is kept stable whilst the hulls react to the waves. Additionally to the passive wave compensation by the suspension system, the deck can be kep at level using the DACS (Deck Attitude Controle System). For transfers to wind turbines via a boat landing the additional bow height control mode adds comfort and safety.
During transit g-forces introduced to the passengers is reduced by approximately 75%. This reduces risk of seasickness and injuries during transit.
The suspension system allows to use smaller boats with the same wave performance. This results in significant reduction of consumed ressources during building. The lesser weight and size of the boats results in a significant reduction of fuel consumption and greenhouse gas emmissions. Example comparison between a Wallaby-18 and a catamaran and a semi SWATH with a similar wave performance:
Finally the above results in ca. >4.000 liter less consumption per day during a standard 24/7 operation and savings of ca. 3.900 tons of greenhouse gases per year. As a much smaller boat can achieve the same wave performance as a larger boat, CAPEX can be split in less than half if payload is not critical.
The Wallaby Boats are all following a general modular approach. This provides highest flexibility for clients to equip the boats as required for the job. Even changes of vessel tasks are possible in very little time. Modules are installed with quick releases. Most items have a twist lock system.
The Wallaby Boats are the first commercial boats applying the Nauti-Craft suspension system. The system is patent protected and Wallaby Boats has the exclusive rights to build the WB-14, WB-15/16 and WB-18. Additionally to the Nauti-Craft patent, the boats incorporate several other patens. E.g. for cables, recovery system and landing method on a WTG.
