Diverse Marine & Turner Iceni complete upcycling of Iceni Defiant


Diverse Marine and Turner Iceni announced the completion of their fourth upcycling refit,
Iceni Defiant which has left the yard and headed straight to contract.

The 17m aluminium catamaran, ‘Iceni Defiant’ was first built in 2012 and has worked continuously through her life, but has been challenged over the last few years with a preference towards larger more versatile craft. According to Diverse Marine and Turner Iceni, the solution was an upcycling refit to extend the working life of the vessel.

Highlights and features of the refit include lengthening of hull and deck by 3.6m as well as the lengthening of technician saloon by 5.5m. The vessel saw and reduction of weight and the doubling of fuel capacity with a 50% reduction in fuel consumption. It also saw a repower to Volvo Penta IPS900 

According to the two companies, the upcycling saw a minor increase to vessel speed performance. It also included a full interior refit to modernise and reduce weight and a full blast and repaint of coatings

Ben Colman, Director of Diverse Marine: “This is the fourth such upcycling refit that we have carried out over the last couple of years and we are very proud to be associated with the life extension of these older assets, installing modern systems and more fuel efficient propulsion packages. These refits compliment and work side by side with our new build programme. As we move toward ‘current generation’ CTV’s having 10 year refits we are actively engaged with operators as to what can be done to modernise these vessels and meet future zero emission requirements.”

Richard Thurlow, Turner Iceni: “Following the success of the ‘MCS Maestro’ to ‘Iceni Warrior’ , ‘MPI Don Quixote’ to ‘Iceni Revenge’ upcycling and life extension refits carried out early in 2019, and the modification and upcycling of ‘Iceni Courage’ in 2020, we had no hesitation in going through the same process with Iceni Defiant. Taking the learnings from these earlier refits and upcycling projects and applying these to Iceni Defiant has truly given her a new lease of life - whilst also making the best use of valuable assets and resources. We really could not be happier.”


The vessel left the yard after the 18-week refit and headed straight to charter on an East Coast project.
