Mr. Schmidt has ever since been highly motivated to participate in developing the offshore wind potentials. As the lead inspector at 8.2 Consulting AG, based in HH, he participated in more than 50% of the German deep water Offshore wind farms, assuring the quality in several different steps and functions, e.g.:
• Monitoring of the production: 6 Offshore Wind farms
• Offshore Inspections: 5 Offshore Wind farms
• Offshore installation and commissioning: 4 Offshore Wind farms
Before his time at 8.2, he was studied mechanical engineering, focused on operation of machinery and quality. He was travelling to sea as an apprentice and has high practical reputation and experience with offshore quality.

Quality assurance and its effect on cost reduction in the Offshore wind branch.
The Offshore Wind Industry represents a strongly emerging market, which is facing different hurdles. Some are technical, some are logistical hurdles and others result from several restrictions related to the environment. As one of the most important and prevailing topics, the cost reduction throughout the whole Industry was a huge factor in the past and will consistently grow in the future. First Offshore wind farms are in operation for several years now and the industry is forced to control costs.
This paper investigates the interdependence between Quality Assurance and project costs.
We consider the requirements on Quality Assurance (QA) from the “main offshore guidelines” in relation to cost reduction: Presentation of the anticipated cost reduction factor, realized by compelling QA and the problem potential of counteractive measures. Show and clarify the relation and the interdependency between the Quality Assurance and cost reduction in the turbine production processes, using related and significant data. The necessity of acting early, document regularly and the need for independent QA will be elaborated. Risks, efforts and possible results will be presented.
Main body of abstract
Cost reduction and the related effects are a major topic in the whole Offshore Wind Industry. The cost reduction effect is highly dependent of several internal and external hurdles, at the different business parties in the Offshore Wind Industry. It will be clarified which aspects and steps in the different topics will lead to a higher quality, followed by lower costs.
Based 8.2’s professional experience and thousands of working hours in more than 60% of the German deep water offshore projects, the problem potential of the cost reduction factor for the turbine design, assembly, erection and operating phase was analyzed.
• The cost reduction factor is highly dependent on the effectiveness of stringent and flexible Quality Assurance.
• The important relationship between Quality Assurance and cost reduction, using cost models with inclusion of anonymized validated data.
• Selected risk – cost analysis, related to real life offshore cases, will elucidate the actual situation in the wind industry and the possible efficiency, realized with synergetic Quality Assurance and competitive management systems.
• Real life offshore examples and the (financial) influences on long term, for selected steps of production, assembly, erection and operation.
• Selected methods for the optimization of QA efficiency.
• QA content for the future: e.g. QA Management systems and the ongoing digitalization of the QA offshore branch with expected improvements.
• The necessary measures/demands which arise from the main Offshore Guidelines: “BSH offshore standards”, “GL offshore guideline 2012”,
Main component Quality assurance and additional part time analysis of smaller components is advised and may especially result in cost reduction. Measures to counteract critical aspects may for example be innovative software solutions of critical milestones within the assembly, until the erection of the Wind Turbines. Further measures and solution possibilities are noticed in the organization of cross-border processes and in systematic influenced areas of between the business partners.
Summarizing, we will present detailed facts, measures and claims, always focused on the cost reduction factor, realized with stringent quality assurance. It will be clarified that many of the present offshore quality assurance concepts are subject to significant optimizations in a difficult environment.
Several aspects and content of deep quality assurance will be presented, to finally clarify for the audience, that the cost reduction will be feasible.
As a result, several aspects still have to be addressed to ensure that offshore borne turbines are “fit for manufacturing cycle efficiency ” in the long term. Lessons are constantly learnt with the first deep water German offshore projects, realized with different turbine types and different customized concepts.
