On the IJsselmeer, The Netherlands, we had several projects for various clients. For example we mention a few of them. For maintenance of the power pylons TenneT selected us to perform crew tender services with the William Wallace and Profiler. With the Spirit we performed survey and crew tender activities for De Vries & Van der Wiel. Using our RIB Esprit we executed survey activities for Boskalis for the ‘Westermeerwind’ project.
