Our experience for your success
On behalf of the company Smulders Project from Belgium, OIS has equipped 165 Transition Pieces (TP) with electrical technology. A multitude of electrical components is required for each TP, which is the connecting piece between the foundation and the wind turbine e.g. power and lighting systems, navigation lights and sonar transponders as well as identification systems and aeronautical lighting. All these electrical devices are supplied for the most part in collaboration with our affiliates SEAR GmbH, fully installed and put in operation. A great deal of the equipment for this project was preassembled in the SEAR workshop of in Rostock and pretested, to ensure efficient installation by the employees in Antwerp. Up to 4 TP`s were brought to completion per week due to a sophisticated preassembly, logistics and installation concept.
Topside DolWin gamma
In 2016, the preparatory climbing works (temporary corrosion protection & scaffolding removal on the jacket / base frame) was conducted by Nordic yards GmbH, which is headquartered in Rostock, on behalf of OIS offshore Industrie service GmbH. This work was conducted in cooperation with our affiliate Krebs Korrosionsschutz GmbH. The preparatory work is an important milestone for the installation phase of the DolWin gamma topside in the North Sea, which is scheduled for the summer of 2017. This is currently the world's largest transformer station.
OWP Baltic 2 - Crane maintenance
The wind turbines in OWP Baltic 2 are equipped with Palfinger PS23500 M cranes. The installation of the cranes on the Monopiles was conducted onshore by OIS Offshore Industrie Service GmbH.

OIS maintained these cranes offshore annually on behalf of EnBW, repaired and subjected them to acceptance tests in accordance with the German Statutory Accident Insurance Association (DGUV) regulation 52 for cranes (BGV D6).
