Offshore Wind

Chartwell Marine is a leader in the design and development of offshore wind support vessels, playing a pivotal role in advancing the global transition to renewable energy. With our deep industry knowledge and a proven track record, we design vessels that meet the evolving demands of the offshore wind industry, supporting the construction, maintenance, and operation of wind farms worldwide.

Crew Transfer Vessels (CTVs)

Our Crew Transfer Vessels (CTVs) are engineered to safely and efficiently transport personnel to and from offshore wind installations, ensuring that operations remain seamless in challenging conditions. We specialise in proven platforms like the Ambitious and Brevity class CTV vessels, which are trusted by leading operators globally.

  • Stability and Safety: Designed with advanced hydrodynamic optimisation, our CTVs offer superior stability and comfort, even in high seas, ensuring safe transfers and minimizing downtime.
  • Efficiency and Sustainability: We prioritise low-emission propulsion systems, offering hybrid and fully electric options that align with the offshore wind industry’s commitment to reducing its carbon footprint.

Service Operation Vessels (SOVs)

Chartwell Marine’s Service Operation Vessels (SOVs) are purpose-built to support offshore wind operations for extended periods at sea. These vessels provide a crucial link in the maintenance and operation of wind farms, offering accommodation, workshops, and storage for technicians.

  • Versatile Designs: We work closely with operators to develop customised SOV designs, ensuring flexibility in operations and providing features that enhance both efficiency and crew comfort.
  • Cutting-Edge Innovation: In collaboration with VARD, we are delivering the Midi-SOV, an industry-leading platform designed to meet the specific needs of offshore wind operators while focusing on sustainability and long-term performance.

Daughter Craft

Our Daughter Craft designs are versatile solutions that can operate both as nearshore CTVs and as vessels deployed from SOVs for maintenance and inspection work. These vessels are built for durability and optimised for efficiency in offshore wind operations.

  • Proven Designs: The Grace Darling Daughter Craft, an award-winning vessel, sets a new standard for efficiency, safety, and comfort in offshore wind operations. This success underscores our commitment to innovation and operational excellence.

Innovation and Sustainability

Chartwell Marine is dedicated to driving innovation within the offshore wind sector, continually evolving our vessel designs to meet the industry’s sustainability goals. Our focus on alternative propulsion systems, such as methanol-powered vessels and hybrid technologies, helps operators reduce emissions without compromising on performance.

We are actively developing new hull forms and propulsion technologies that support zero-emission operations, playing a key role in decarbonizing the maritime industry.

Offshore wind portfolio

Ambitious Class CTV

The Chartwell Ambitious Class CTV is a pioneering crew transfer vessel that redefines the formula for green offshore wind support when combined with hybrid propulsion.
