Commissioning service operation vessels (CSOVs) vary widely in both size and design, depending on their specific application, meaning they must be built for purpose. As they are often working in demanding conditions, they need advanced dynamic positioning and a high operational window for maximum uptime offshore. They also typically need significant accommodation space and motion-compensated walk-to-work gangways. Vessels should be fully digitised, connected and highly automated, with next-generation technology. With an increasing need for decarbonisation in the industry, carbon emissions and efficiency optimisation are also key.
