WALLABY-18
Large daughter craft and small crew transfer vessel
The Wallaby-18 is a high performance catamaran that can be used as a large daughter craft on far offshore Service and Operation Vessels (SOV), as they will be used e.g. on Dogger Bank offshore wind farms. This prototype brings the suspension boats' technology to TRL 7. As a result to its rather large dimensions for a daughter craft, the Wallaby-18 is a powerful yet economic crew transfer vessel (CTV) for nearshore offshore wind farms. Passenger comfort, economy and carbon footprint of the WB-18 are stunning. It compares in wave performance to 24m - 28m catamarans but CAPEX, OPEX and carbon footprint are significantly lower (50%-60%) at same wave performance.
In the future the WB-18 will not be built as CTV but it will be the perfect pilot boat in rough sea state.
It provides for a safe access and still is fast and economical.

Wave performance simulation (ADAMS)
ADAMS simulations of the latest vessel design of the WB-18 show stunning results.
Even at 2,0m Hs, the vessel is easily fulfilling the Carbon Trust definition of a safe transfer in all angles of attack.
Carbon Trust Definition of a "Safe Transfer"
- Roll RMS max. 3,0°
- Zero slip confidence level min. 95%
- Slip size max. 0,3m
