Balance of plant (BoP), inspections, repair and maintenance

To minimize downtime and the cost of repairs, C-Ventus believes in a pro-active operations & maintenance concept, based on in-depth familiarization with the characteristics of a specific windfarm. C-Ventus has been  rendering long term operations & maintenance services to various windfarms in Western Europe and as such has developed  tailor made service packages for the operators of these windfarms. The overall goal being to bring down costs within a safe and healthy working environment, we reduce and streamline interfaces, utilise synergies and combine the strengths of all stake holders in continuous and close consultation. We provide local support and a single point of contact, available 24/7, managing and overseeing the scope of work and the challenges posed by offshore assignments. All data collected in the process, including status updates on all components, can be made available real-time in order to determine condition and evaluation of critical items and to enable timely intervention and remediation.

Research, development, testing and installation of conceptual products, tools and programs


Having a pro-active outlook and striving to supply complete support during the entire economical life-cycle of offshore windfarms, C-Ventus has already started to develop decommissioning plans for a number of clients in order to aid in the preparation of methodologies, inclusive of required resources and time-schedules, as well as corresponding budgets. On that basis C-Ventus has been able to identify the potential financial exposure in relation to decommissioning which subsequently has been translated into realistic financial provisions for these works.
