The two CSOVs (commissioning service operation vessels), ordered at Vard in July by a still-undisclosed buyer <\/a>will have complete propulsion and maneuvering systems supplied by Brunvoll.<\/p>\n Each vessel will be equipped with the following Brunvoll solutions from aft to bow: two azimuth propulsion thrusters, a retractable azimuth thruster, a tunnel thruster, and a combined retractable azimuth and tunnel thruster. The scope of supply also features Brunvoll\u2019s BruCon PTC propulsion and thruster control system,<\/p>\n The azimuth propulsion thrusters are equipped with Brunvoll\u2019s latest energy-efficiency innovation, the DL1-nozzle, also known as the \u201cDragless\u201d<\/a>. While traditional nozzles experience an efficiency drop at transit speeds, the DL1 maintains favorable hydrodynamic characteristics across a broader operating range. More information about the nozzle and its features is available at www.brunvoll.no\/news\/the- dragless-nozzle.<\/p>\n The vessels are based on are based on the upgraded Vard 4 19 design, developed by Vard Design in \u00c5lesund, Norway. and have following main particulars: length of 87.5 meters, beam of 19.5 meters, and accommodation capacity for 120 persons, along with all equipment required for a CSOV.<\/p>\n The design has been customized to the customer\u2019s needs to give environmental benefits, featuring a hull optimized for low fuel consumption, high operability and onboard comfort. The hybrid battery propulsion system allows for periods of zero-emission operation, provides additional peak power when required, and ensures an energy-efficient profile across all activities. In line with sustainability goals, the vessels are also prepared for future methanol operation.<\/p>\n The post Brunvoll to supply complete propulsion and maneuvering solutions for two new CSOVs<\/a> appeared first on Marine Log<\/a>.<\/p>\n<\/div>\n![\"Brunvoll-equipped](\"https:\/\/i0.wp.com\/www.marinelog.com\/wp-content\/uploads\/2025\/10\/Brunvoll_VARD_CSOV-x2_2_Credit-to-VARD.jpg?resize=700%2C525&ssl=1\")
