Decommissioning and lifespan extension are two different worlds
In offshore wind decommissioning means disconnecting and dismantling wind turbines that are at the end of their lifecycle. They are disconnected from their moorings and cables and towed back to port where they are dismantled into smaller components. These are either fit for reuse, recycling, or disposal. Although decommissioning is a much faster process than commissioning, or installing, wind turbines, it is a process that requires high-end customized engineering.
Alternatively, lifespan extension aims at prolonging the operational life of offshore wind turbines. Well thought-out maintenance plans supported by smart engineering prevent the decommissioning of wind turbines. Although fairly new, this development cannot be reversed and challenges the maritime engineering industry to invent new solutions.
