Nauti-Craft and Strategic Marine secure 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."

Nauti-Craft succesfully completes its fifth project under UK Carbon Trust’s access innovation program.

Nauti-Craft has recently completed its fifth project with funding assistance from the UK based Carbon Trust under its Offshore Wind Accelerator (OWA) program.
The OWA is the Carbon Trust's flagship collaborative RD&D program set up in 2008 with the aim of reducing the cost of offshore wind by 10% through innovation. Technology challenges were identified and prioritised by the OWA members based on the likely savings and the potential for the OWA to influence the outcomes in the offshore wind industry.
The OWA is a joint industry project, involving nine offshore wind developers*
In 2011 Nauti-Craft Pty Ltd was one of 13 finalists chosen from 400 submissions to receive funding assistance because of its unique and novel marine suspension technology which provides safer crew transfer and transit to offshore wind turbines.  
Being chosen as a finalist for the competition opened the door for Nauti-Craft to access the support of The Carbon Trust with a succession of projects aimed at assisting in the commercialisation and de-risking of the Nauti-Craft technology.
Support of the Carbon Trust and its Working Group Partners has assisted Nauti-Craft in taking it’s novel marine suspension technology from initial concept stage through to a commercially viable working prototype that has led to commercial agreements aimed at introducing the technology into the European offshore windfarm service vessel fleet.
Milestones have included scale model tests leading to the design, construction and sea trials of 8 metre prototype (including industry demonstrations in Europe at Seaworks 2014) and culminating in the most recently completed project in a Design Approval Preview by DNV GL for a 26 meter windfarm service vessel

Nauti-Craft’s Managing Director Ken Johnsen stated “Without the Carbon Trust’s assistance the Company would not have achieved its rapid progress in arriving at a viable solution for the offshore wind industry. Not only the financial assistance has been valuable. Equally as valuable is the industry exposure facilitated by the Carbon Trust and the Working Group of the OWA.
Nauti-Craft would like to thank the Carbon Trust and its partners and  looks forward to a ongoing relationship.

Nauti-Craft’s Revolutionary Windfarm Vessel Design Achieves Important Pre-Classification Review by DNV GL

Nauti-Craft Pty Ltd, in partnership with the Carbon Trust, has recently successfully undergone a Design Approval Preview (DAP) with DNV GL.

The Carbon Trust’s Offshore Wind Accelerator has supported Nauti-Craft for four consecutive years to help deliver on the programme’s objective to reduce the cost of energy from offshore wind for sites located further offshore. With the help of the OWA Nauti-Craft vessel was demonstrated to industry at Seawork International in Southampton, UK last year. This final phase of support has enabled Nauti-Craft to identify and address remaining challenges to ensure the concept achieves classification approval from DNV GL, a key requirement for this concept to operate in the offshore wind market.

Nauti-Craft technology allows for a cheaper, safer and more efficient means of transportation and access to offshore wind farms in more onerous weather conditions. Increasing the turbine accessibility increases the availability of the turbines and hence reduces the cost of the energy produced.

DNV GL is the world's largest classification society, an autonomous and independent foundation with the objectives of safeguarding life, property and the environment, at sea and onshore. DNV GL undertakes classification, certification, and other verification and consultancy services relating to quality of ships, offshore units and installations, and onshore industries worldwide, and carries out research in relation to these functions.

The Design Approval Preview involved a thorough review of the preliminary design, stability, systems engineering and safety for a 28m crew transfer vessel design, aimed at providing a general assessment and identify potential risks or issues that might prevent Classification being granted by DNV GL.

The summary report from DNV GL states:

“Based on supplied information, no significant issues have been identified that would prevent Classification being assigned to this vessel.”
Nauti-Craft’s Naval Architect Anthony Livanos managed the review and said the whole process with DNV GL was conducted proficiently and ran smoothly.
“The positive feedback and support from DNV GL is very encouraging. The fact that no significant issues were identified to prevent class being attained is a testament to our design team and the robustness of our windfarm vessel concept. The successful review accelerates our design program to be able to provide a unique solution to the rapidly expanding offshore windfarm industry.” Mr Livanos said.
The crew transfer vessel concept is progressing into the detailed design stages while Nauti-Craft has initiated a review with a European Flag administration and a Western Australian shipbuilder.
Ken Johnsen, Nauti-Craft’s Managing Director stated, “The DNV GL review is an important pre-cursor to the commercial availability of innovative new vessels incorporating the Company’s innovative technology that will enable safer and more comfortable transit to offshore windfarm installations and once at site safer technician and load transfer. The Company is appreciative of the Carbon Trust’s ongoing support in achieving this important milestone. ”

Dan Kyle Spearman, Project Lead, Access and Transfer Systems at the Carbon Trust commented: “We identified the potential for the Nauti-Craft concept to improve accessibility to offshore wind turbines four years ago when it was selected as one of the final concepts from over 450 international entrants in our global innovation competition. This report from DNV GL is an important step in de-risking the concept and showing that this novel design can achieve marine regulatory approval. This is really positive news that a Carbon Trust and OWA supported concept has reached this stage and I am looking forward to seeing a Nauti-Craft vessel operational on a wind farm.”


Nauti-Craft Technology Showcased at Offshore Windfarm Conference in Copenhagen

Senior executives of Nauti-Craft were delegates at the European Wind Energy Association’s (EWEA) “Offshore 2015” conference held in Copenhagen on March 10 to 12, 2015 where the Nauti-Craft technology was showcased to over 8,000 participants from 50 countries.

German companies Offcon GMBH, a offshore consulting company, and Reederie NSB, a vessel operator, showcased a windfarm support business model that incorporated the use of Nauti-Craft’s 12.5 meter “daughter craft’ concept to service wind farms. The support model displayed by Offcon showed the Nauti-Craft vessel that could dock onto the rear of a 60 meter catamaran mother ship.


Nauti-Craft Managing Director Ken Johnsen stated after returning from the conference; “ I was very pleased to see the level of exposure given to the Nauti-Craft technology and a means to provide an improved crew transfer solution to wind farm operators. During 2014 there was a 20% increase in the number of wind turbines installed in European waters taking the number to over 2500 turbines. This rate of growth is expected to continue in coming years with a proportionate increase in the number of vessels required to service and support these turbines. Based on the level of interest expressed from major operators in this market Nauti-Craft believes it can play a large role in the market.”

Nauti-Craft’s had previously received strong interest from the wind farm industry due to the support of UK based Carbon Trust that contributed financially to the development of a 8.5 meter “2Play” demonstrator vessel which was unveiled to the industry at the Seaworks 2014 in Southampton UK last June.

Mr Johnsen commented – “the exposure at Seaworks carried over to the Copenhagen conference where a wide part of the Company’s target audience had knowledge of the Nauti-Craft technology. This led to some very productive commercial discussions with key participants in the industry.”
