Reflections on integrating operation and maintenance activities of offshore wind farms and mariculture

Offshore waters are in a process of transition, revealing diverse and heterogenic interests in marine resources. This increasing complexity leads to limits in developing and managing the different and often spatially overlapping maritime activities independently of one another. On a showcase basis we discuss ways and manners as well as the preconditions of an offshore co-management approach for the fledgling actor groups offshore wind farmers and mariculturists. Both groups may benefit through the integration of operation and maintenance (O&M) activities. Their resources in terms of offers, needs and constraints characteristics and thereof deduced potentialities for interaction is a prerequisite for initiating a co-management process. This process is more likely to develop and succeed if an interface management that acts as a moderator, disclosing the interests of the actor groups and offering possibilities for concerted action, guides it. It is concluded that such an institutional arrangement may in the long term contribute to a sound methodological tool for a co-management approach between different offshore maritime sectors.
