Sentinel Marine's innovative DP2 vessel contract

Sentinel Marine, a member of the Cyan Renewables Group, has signed a shipbuilding contract with Jiangmen Hangtong Shipbuilding Co., Ltd for the construction of a 65-metre multi-role energy support vessel to join their fleet, with options for a further three vessels. The new vessel will bring the fleet number to 15. The initial vessel in this innovative new class is scheduled for delivery in Q2 2027. The newbuild will be a DP2 vessel with a deadweight of 1,600 tonnes, with 375m² of clear deck space and substantial under-deck capacity for fuel oil, potable water, recovered oil, and mono ethylene glycol (MEG). Dutch and Danish ERRV regulations Design includes an optional work-to-work gangway, an under-deck supplies storage and hybrid propulsion Designed as a Group B (A option) UK emergency response and rescue vessel (ERRV), the vessel will feature a fast rescue craft (FRC) and hybrid daughter craft. This transitional vessel will also meet design criteria for Dutch and Danish ERRV regulations and will offer accommodation for between 37 and 47 personnel. In addition to its emergency response capability, the design includes an optional work-to-work gangway, under-deck supplies warehouse and battery hybrid propulsion, ensuring suitability for a broad range of operations, including offshore wind and transitional energy support, government services, carbon capture, and maritime security. Innovation in marine operations Rory Deans, CEO of Sentinel Marine, says, "This new vessel, and the future sister ships, mark an exciting step forward in our strategic vision to deliver ‘Blue to Green' operations. The new vessel will be a cornerstone in our journey towards cleaner, multi-sector marine services that remain robust and reliable." Keng Lin Lee, CEO of Cyan Renewables, said: "Cyan is delighted to be investing in expanding our fleet with this innovative new multi-purpose support vessel enhancing Sentinel's reputation as the pioneering UK-based ERRV provider with the youngest fleet in Europe. The investment aligns with Sentinel Marine and Cyan Renewables' shared commitment to sustainable innovation in marine operations, strengthening the group's capabilities across multiple offshore sectors."

Brunvoll powers Cyan Renewables' new SOV with innovative propulsion system

Brunvoll has signed a contract with VARD for the delivery of a comprehensive propulsion and manoeuvring system for Cyan Renewables new Service Operation Vessel (SOV). Azimuth propulsion thrusters The vessel will have the first azimuth propulsion thrusters from Brunvoll with an 8-degree tilted propeller and nozzle, for enhanced performance during dynamic positioning operations. The delivery for the new SOV consists of two azimuth propulsion thrusters, two retractable azimuth thrusters, a tunnel thruster, and Bruvoll’s Propulsion and Thruster control system. Tilted propeller The azimuth propulsion thrusters will be the first deliveries with an 8-degree tilted propeller and nozzle The azimuth propulsion thrusters will be the first deliveries from Brunvoll with an 8-degree tilted propeller and nozzle. The tilted propeller contributes to increased efficiency in terms of reduced thruster and hull interaction, known as the Koanda effect. It also reduces the dead zones for the azimuth thruster, where the propeller wake normally interacts with the skeg or other thrusters on the vessel. Offshore wind vessel "Brunvoll is proud to partner with VARD and Cyan, and it’s a pleasure to welcome Cyan, as Asia’s first dedicated offshore wind vessel owner, as a customer of Brunvoll," says Bernt Rune Riksfjord, VP Sales at Brunvoll. Bernt Rune Riksfjord adds, "We would also like to thank VARD for once again returning to Brunvoll with new and exciting projects and opportunities." VARD-designed vessel The VARD-designed vessel will be built at VARD’s shipyard in Vung Tau in Vietnam. The vessel will become 85.5 meters in length, a breadth of 19.5 metres, and be able to accommodate 83 crew members and wind technicians.  The vessel is scheduled to be delivered in Q2 2026 and will enter into operation for Siemens Gamesa at the Hai Long Offshore wind farm in Taiwan.

Cyan Renewables contracts Ulstein Design & Solutions BV to design new floating foundation installation vessels (FFIVs)

Singapore-headquartered Cyan Renewables has contracted Ulstein Design & Solutions BV as the designer of a series of new floating foundation installation vessels (FFIV) dedicated to offshore wind. With an increasing lack of heavy lift installation vessels, these new FFIVs are needed to fill the gap. The vessels will enable Cyan to support the offshore wind industry in meeting its global ambitions. “With their strong track record in heavy lift vessel design and a good understanding of the market constraints and requirements, Ulstein are the preferred partner to design our new vessels," says Torgeir E. Ramstad, Cyan’s Managing Director FFIV Division. Cyan Renewables contracts Ulstein Design for new FFIVs Torgeir E. Ramstad adds, “Cyan Renewables will be a leading global vessel provider to offshore wind by partnering with developers and EPCI and T&I contractors, based on future-proof vessels in all categories.” Back in time, we predicted a lack of foundation installation vessels" “We are very pleased that Cyan recognises our added value and is placing their trust in us to realise their ambitions in offshore wind”, says Edwin van Leeuwen, Managing Director at Ulstein Design & Solutions BV., adding “Back in time, we predicted a lack of foundation installation vessels and as developments goes fast, our R&D focus has been on future-oriented FIV designs to suit the exponential growth of offshore wind." State-of-the-art designs The new FFIVs will feature adequate deck space and crane capacity to meet developments in foundation design, including monopiles and jackets. In addition, they will also have low emission capability, using a hybrid power system consisting of dual-fuel engines (methanol), shore power and a battery energy storage system. Ulstein blended design method “Part of our R&D work included a new method to develop the business case and ship design simultaneously. With this Ulstein Blended Design method, we explored thousands of ship designs to find the most future-proof solutions," says Ko Stroo, Product Manager/Lead Naval Architect in Ulstein Design & Solutions BV. Ko Stroo adds, “Working with multiple future growth scenarios for offshore wind, allows us to support Cyan in finding the optimum business case and vessel design.”
