Diverse Marine & High Speed Transfers announce build of two further CTV’s on First Day of Seawork 2022

21 June 2022

Cowes, UK (21-06-22) – Diverse Marine and High Speed Transfers are proud to announce the contract signing of two further hybrid propulsion Chartwell Marine Ambitious Class CTV’s, following on from the success of ‘HST Ella’ delivered last summer.


The international expansion of the offshore wind sector is creating significant opportunities and challenges for the maritime supply chain and rewarding operators, builders and designers of innovative craft that meet legislative requirements, whilst reducing vessel emissions and fuel consumption.

These two new vessels, to be named ‘HST Frances’ and ‘HST Millie’ are developed sisters of ‘HST Ella’ that incorporate subtle changes following the operation of the vessel on multiple European projects over the last few months.


The catamaran’s unique hybrid propulsion system incorporates an electric motor alongside a diesel engine, which drives a high-performance changeable pitch propeller (CPP) system. At low speeds, such as port departure and arrival or whilst loitering in the wind farm zone, this allows for silent, zero emissions operation enabling the vessel to comply with port air quality requirements. At transit speeds, it can perform capably and efficiently while ensuring the comfort of technicians. The Chartwell Marine hull form with high bollard push and superior bow height ensures confident transfer at high wave heights.


Other features of the two new craft include enhanced foredeck capacity and wheelhouse visibility, which enables skippers, crews and technicians to safely navigate challenging logistical assignments. For HST, the vessels will support an ongoing commitment to the highest standards of service for offshore wind farms, while adding new levels and standards of efficiency, versatility and flexibility.


Ben Colman, Director of Diverse Marine said, “The maritime supply chain in the UK has had many challenges over the last few years but it continues to demonstrate that the UK is leading the way with innovations that will define the way vessels are built and operated worldwide. We are very proud of ‘HST Ella’, its innovation, its world class quality and the benefits and opportunities the craft provided us, our local Isle of Wight supply chain and how it demonstrated the very best of UK Shipbuilding capabilities. ‘HST Frances’ and ‘HST Millie’ further demonstrate the collaborative working of successful operator, builder and designer to produce environmentally friendly vessels and I am very proud of Diverse Marine’s relationship with HST and Chartwell as we deliver these vessels and the next generation of vessels that follow.”


Tom Nevin, Chief Executive Officer, HST added “HST Ella was successfully delivered by Diverse Marine last year and she has proven to be highly capable with the hybrid system exceeding our targets of reducing emissions and fuel consumption. We are very pleased to be working with both Diverse Marine and Chartwell Marine to deliver these two new vessels while we continue to work with the same team to define our next generation vessels.”

Andy Page, Managing Director, Chartwell Marine added “We are excited to be working with HST and Diverse Marine again to deliver these innovative hybrid CTV’s to market. As the drive towards greener operations gains momentum it is important that we tackle the emissions challenge head on, without losing sight of the key attributes that define effective offshore wind vessel support.”

Diverse Marine’s Finance & Lease Programme Delivers Two CTVs, with Five More in Build

27 February 2025
Cowes, UK (27-02-25) Since launching its Finance & Lease Programme in November 2023, Diverse Marine has successfully delivered two crew transfer vessels (CTVs), with three more currently in build for delivery this year and two further shortly thereafter of the first batch.The programme continues to operate as a rolling initiative, providing new-build CTVs based on customer demand. The first vessel completed under the programme was NR Alpha, which was unveiled at Seawork last year. This Storm Class CTV has set new benchmarks for fuel efficiency and performance, leading NR Marine Services to order a third vessel—NR Rival, the first of the new Typhoon Class CTVs. NR Rival was delivered in January 2025. TheTyphoon Class features a hull form designed for exceptional head-sea performance and tower access while maintaining high buoyancy reserves for superior seakeeping in following and stern-quarter seas. It also comes with Zero Emissions (Power Management) class notation, recognising its efficiency in reducing fuel consumption and CO2 emissions. Stock Build 3, a first Brevity Class CTV is undergoing sea trials with the vessel available for quick delivery following rebrand to suit a prospective clients requirements. Stock Build 4, to be named NR Rebellion, a second Typhoon Class CTV, is now in its final build phase, with the wheelhouse and saloon fitted earlier this month. Again ordered by NR Marine Services, she is scheduled for launch and sea trials in March. Owen Nutt, Director at NR Marine Services, commented: “Receiving three world-class CTVs in the last 10 months has been transformative for our business. Each vessel has outperformed expectations in speed and efficiency, delivering significant fuel cost savings for our clients.This success has given us the confidence to order another Typhoon Class CTV and another Storm Class CTV through Diverse Marine’s Finance & Lease Programme, and we look forward to putting them to work soon.” Meanwhile, Stock Build 5, to be named NR Hunter, a third Storm Class CTV, is currently under construction at Diverse Marine’s facility in Cowes and will be launched at Seawork in June. Stock Build 6, an Ambitious Class CTV is also currently under construction and will be delivered to OEG, whilst Stock Build 7, a further Brevity Class CTV, will follow in Q3/Q4 of this year. Ben Colman, Director at Diverse Marine, added: “The success of our Finance & Lease Programme is proving that high-quality, next-generation CTVs can be more accessible and affordable for operators. By reducing the financial barriers to vessel ownership, we’re enabling companies to upgrade their fleets with more efficient and capable vessels. With four more vessels in build and strong interest in future slots, we look forward to continuing to support the offshore wind industry with innovative financing and cutting-edge designs.” For more information on the Diverse Marine Finance & Lease Programme, including availability and build slots, please contact Ben Colman or Peter Curtis on 01983 300656.

Diverse Marine Start Construction of CSOV Daughter Craft

12 June 2024
Seawork, Southampton, UK (12-06-24) Diverse Marine is proud to announce that it has been selected by VARD GROUP AS to construct a Chartwell Daugher Craft to be installed on a VARD 4 19 CSOV under construction for PURUS Wind.

Diverse Marine & NR Marine Services announce the launch of NR ALPHA

10 June 2024
Diverse Marine and NR Marine Services and proud to announce the launch of the second of class Storm Class CTV, NR ALPHA that is now proudly being displayed at Seawork 2024 in the Port of Southampton on berth VB21. NR ALPHA is a sister to NR PREDATOR delivered in March this year. NR PREDATOR has performed very well on her first contract with higher performance levels and substantially lower fuel burn and emission levels than other similar vessels on the same project. The Storm Class measures 27.6m LOA by 10m BOA and is fitted with a quad IMO Tier-3 Volvo Penta IPS propulsion system. Its unique hull form features a very fine entry with higher buoyancy reserves above the main chines and resistance reducingsolutions integrated into the underbody. A resilient superstructure ensures very low noise and vibration levels in the passenger saloon with the first recording sub 55dBA at full power. NR ALPHA is the first vessel from the Diverse Marine Finance and Lease Programme announced late last year and the first of three vessels being delivered to the scheme this year. The programme allows Diverse Marine to build offshore wind crew transfer vessels to stock for onward lease or sale. The scheme removes the requirement for clients to source construction finance and Diverse Marine can offer the vessels on lease/hire purchase with 0% deposit, a fully funded solution with payments monthly in arrears. Ben Colman, Director of Diverse Marine:“We are delighted to announce the build of NR ALPHA for NR Marine Services.Theperformance of NR PREDATOR has exceeded everybody’s expectations with exceptionally good performance, fuel efficiency and reliability, a testament to the high quality produced by our team at Cowes”.  Owen Nutt, Director of NR Marine Services: “The addition of NR ALPHA to our fleet so soon after NR PREDATOR is testament to the growth and forward plans set out by our business to add high quality, high performance and efficient vessels to our fleet. Diverse Marine’s Storm Class is the result of the KPI’s we provided to Walker Marine Design and the ship yard. With NR PREDATOR all of these KPI’s were met with the vessel proving to be faster and more efficient that predicted. We are very pleased and excited that we can add NR ALPHA to the fleet and provide our clients with class leading vessels that can save £100,000’s of fuel cost annually without any compromise”.
