This report is part of i4offshore project: Integrated Implementation of Industrial Innovations for Offshore Wind Cost Reduction. The goal of the project is to produce a full demonstration structure supporting an offshore wind turbine +10MW that reduces costs of production and assembly for the industry. The four-legged structure is designed to be supported on suction bucket foundations with innovative shape named modular bucket that reduces significantly the cost of assembly and can be produced and assembled industrially, this concept was developed under Energy Technology Development and Demonstration Program (EUDP): offshore wind turbines suction bucket foundation on industrial scale. The present report focus is the installation of the suction bucket foundations which will be analysed for a specific location. The analysis carried out is supported by previously performed trial and full scale installations as well as laboratory scaled tests. Additionally, the approaches proposed by API and DNV are utilized to provide further estimations of the resistance encountered during the installation. At last, a finite element model in 3 dimensional space is described and used to compute the critical pressure that would generate a hydraulic failure of the installation. The model is also used to observe the group effect of installing four foundations at the same time.
