Approval for the design of the Nauti-Strat26 Windfarm Vessel.

Nauti-Craft and Strategic Marine have successfully secured important Approval in Principal from DNV-GL for the design of the Nauti-Strat26 Windfarm Vessel.

The development of the NautiStrat-26 WFSV took a major leap forward with the receipt of an Approval In Principal of the vessel design basis by classification society DNVGL.

This approval confirms the approach and methodologies developed by Nauti-Craft to design its unique suspension system for Strategic Marine’s 26m wind farm service catamaran are acceptable for the purposes of achieving Classification of the completed vessel design.

The development of a vessel, which departs so significantly from traditional design methods, presented a number of significant challenges as established codes or rules could not be applied.

Using a variety of techniques, extending from first principles engineering to highly complex computer simulations, the team at Nauti-Craft provided DNVGL with a comprehensive analysis of loads, forces and accelerations anticipated to be experienced by the vessel operating in often severe conditions in the North Sea.

Nauti-Craft’s Operations Manager, Dr Laurie Walker commented:

“One of the key challenges was to demonstrate how a traditional vessel would be seeing up to 3g of slamming accelerations while the Nauti-Craft superstructure would only experience up to 1g. The Nauti-Craft team had to develop a unique design method in relation to this type of vessel including identifying worst case loading conditions.”

Jay Elatam, Strategic Marine’s Project Manager stated:

“This is an engineering milestone and ground breaking for DNVGL as a project. As the Nautistrat-26 concept is such a radical departure from the typical catamaran and hence class rules, DNVGL acceptance on the load calculation method forms a solid foundation in designing future vessels fitted with this ride control system.”
