For offshore wind farms which are planned in sub-arctic regions like the Baltic Sea and Bohai Bay, support structure design has to account for load effects from dynamic ice-structure interaction. There is relatively high uncertainty related ice loads as little no load- response data of turbines exposed drifting exists. In present study potential development ice-induced vibrations an turbine on ...

We investigate how an organizational structure and culture are affected by legacy products and, in particular, if an inverse Conway’s law holds: “Developer culture for a legacy product mirrors the culture of organizations that created and maintained that product in the past.” We study three large products that were offshored and the entire development team has been replaced with an offshore tea...

Fatigue design and certification of OWT is a special challenge. As the turbine manufacturers are reluctant to share detailed turbines information and the offshore contractors have not full knowledge of integrated OWT design, integrated and non-linear time domain simulations are too cumbersome. A simplified approach is proposed, that requires complete separation between turbine and support struc...

In this paper we develop a learning-mediated model of offshore software project productivity and quality to examine whether widely adopted structured software processes are effective in mitigating the negative effects of work dispersion in offshore software development. We explicate how the key process areas of the capability maturity model (CMM) can be utilized as a platform to launch learning...

In the structural optimization problem, the aim is to decrease the amount of structural costs and weight, but the safety of platform should not violate the individual limits enforced by offshore codes. The outer diameter and thickness of members are two important variables in the optimization process and their final dimensions should be obtained according to the optimization algorithms such as ...

The results of a major research programme into the cost effective use of fibre reinforced composites offshore, undertaken as a Joint Industry Project by a consortium of universities and contractors are presented in this report. The report includes a detailed (54 page) summary of current offshore composite applications, followed by a review of the 43 projects conducted during the programme which...

Background Despite the particular demands inherent to offshore work, little is known about the working conditions of employees in the German offshore wind industry. To date, neither offshore employees' job demands and resources, nor their needs for improving the working conditions have been explored. Therefore, the aim of this study was to conduct a qualitative analysis to gain further insight ...
