Diverse Marine completes early delivery of ‘Iceni Valour’ to Turner Iceni despite challenges of pandemic

18 March 2021

Diverse Marine, the industry leading workboat constructor and refit/repair provider is delighted to announce the early delivery of the offshore wind crew transfer vessel ‘Iceni Valour’ to Turner Iceni. The vessel arrived successfully ahead of schedule in North Wales, to commence her 10-year charter in the Liverpool Bay area.

 

‘Iceni Valour’ is a 24m aluminium CTV designed by Walker Marine Design to meet the specific requirements of Turner Iceni and their long term client. Every aspect of the vessel has been designed to maximise vessel reliability and provide the highest levels of comfort for both the crew and the technicians.


Powered by twin MAN D2862 LE263 1400hp main engines with ZF3050 gearboxes and Hamilton Jet HM651 water jet units, the vessel achieved sprint speeds of 29 knots - maintaining a service speed in excess of 25 knots. With 12,000ltrs of fuel and 12 technicians, the vessel can carry 20,000 kg of deck cargo with only a modest reduction in performance. The hybrid ready Hamilton Jet AVX control system also provides station keeping using the Jet-Anchor function to enable low fuel consumption position lock whilst standing by offshore.


Sea trials during February demonstrated minimal speed loss in higher sea states to ensure the vessel remains operational in the harshest of operating conditions. Twin 37kw NANNI generators provide 400V to the switchboard, providing ship wide hotel loads, as well as a power pack for the crane and winch.


The resiliently mounted deckhouse ensures very low vibration, with noise levels of just 58DbA in the passenger saloon at 25 knots. The technician space benefits from Turner Iceni’s considerable experience as a CTV operator and features, shock mitigating seating, automatic climate control, large window areas, concealed lighting, a forward access door together with underfloor heating to ensure the space remains dry on the wettest days. The flat foredeck provides safe and secure access to on/offshore assets.


The bridge provides a next generation configuration for CTV’s, designed with a minimalist helm console with only essential equipment positioned for the skipper, to ensure that all controls are within arcs of movement. Twin Furuno TZ Touch 19” monitors provide the heart of the vessels navigation and communications with the ability to share information to twin 42” and one 32” Hatteland monitors using Furuno Time Zero. At the core is an augmented reality system using a FLIR thermal camera to show AIS targets, routes, waypoints and navigation hazards over a video screen in real time. All non-essential equipment is located aft on a separate console enabling the crew to interrogate all systems without compromising the safe navigation of the vessel.


As Ben Colman, Director of Diverse Marine states, “We are immensely proud of what has been achieved with this build. Our team have worked exceptionally hard through the challenges of a global pandemic to deliver ‘Iceni Valour’ early to the client, but also on budget and to the highest standard. The result is very impressive.”


Richard Thurlow of Turner Iceni adds: “Collectively, with our teams in Lowestoft and Glasgow, we operate a recognised world class standard of service to our clients with world-class British designed and built boats. I am blown away by the quality from Diverse Marine and for delivering ‘Iceni Valour’ in the most challenging of climates.”

NR Marine Services commissions Chartwell Marine to bring a new legacy turbine vessel to the market

11 June 2025
Southampton, 17th June 2025 — NR Marine Services is excited to announce that it has commissioned Chartwell Marine, a trusted pioneer of next-generation vessel design, to design a new CTV in response to client requests for a new class of vessel that is capable of supporting older generation assets, now referred to as legacy turbines, but utilising modern construction and outfit technology to maximise vessel fuel efficiency and technician comfort. It has been a generation since UK based Naval Architects and Shipyards designed a sub 22m, sub 60 tonne, sub 3m bow height crew transfer vessel. Chartwell Marine has developed the ‘Defiant Class”, a 20m CTV designed to Workboat Code Edition 3 with IMO Tier 3 compliance featuring a step free flush forward deck, resiliently mounted superstructure and modern furnishings and materials used in larger CTVs. This is a bold, DEFIANT step to do different, to create a new class of smaller CTV required for legacy turbines whilst not losing the core identity of modern UK designed, UK built and UK operated CTVs. DEFIANT in compliance, this new class of CTV will comply with Workboat Code Edition 3, IMO Tier 3 and the spirit and core fundamentals of HS_OSC – albeit in a more cost-effective approach. DEFIANT in pricing, it is essential the new class is cost effective in the modern market. UK quality but smartly sized to benefit from UK supply chain core strengths and therefore pricing. DEFIANT in reliability, working with supply chain to integrate a new, smaller Quad IPS IMO Tier 3 or Hamilton Waterjet propulsion solution with high power to weight ratio whilst maintaining simple, quality and reliable engineering. DEFIANT in change, accepting most legacy turbines have unique site requirements, the vessel retains flexibility to be tailored to different projects from a water jet propulsion system for shallow water sites and hybrid options where budgets allow to internal modularity to suit different racking and seating solutions. Andy Page of Chartwell Marine Ltd. said: “It is always enjoyable bringing a new class of vessel to the market. What’s interesting in this case, is the vessel is based-on “legacy vessel” parameters but with modern up-to-date experienced thinking. With the Defiant Class, we are able to utilise our proven high efficiency, high seakeeping performance hull form, in a smaller, more dynamic cost-effective platform, appropriate for the legacy turbine projects the vessels are intended to support”. Richard Thurlow of NR Marine Services Ltd. adds: “NR Marine Services is excited to be the first to bring the brand-new Chartwell DEFIANT Class CTV to the market. With strong industry focus being on the HSOSC market space, the CTV development has been taken away from the smaller vessel market. Working closely with Chartwell Marine and Diverse Marine we have looked at incorporating as many of the recent CTV developments a possible into a smaller package. Step free access from deck level to bow step over point, tiered seating, Male and Female heads, comprehensive galley suite and optimised hull design for near shore projects. Following an internal fleet review long with external market research, the data shows that there is a potential to replace older tonnage which is between 10-15 years old for near shore projects which have a lifespan that warrants investment in new CTV’s”. Ben Colman of Diverse Marine Ltd. adds: “Many years ago, the UK proved that building large numbers of smaller CTV’s was possible but these times have been forgotten as the CTV industry as evolved into larger. HS-OSC compliant craft. It is both exciting and challenging to be involved a project to build a new smaller CTV that meets the growing demand for legacy turbine access with modern technological compliance, modern materials, high fuel efficiency, hybrid options. Put simply the Defiant hosts, a modern, clean and spacious environment but on a smaller highly efficient platform that suits the smaller harbours, short transit sites and shallow water projects."
