With 2020 drawing to a close, it’s a good time to look back in review. "We had numerous very diverse offshore deployments this year", says b.offshore director Thomas Pontow, and highlights three particular projects.

b.offshore GmbH carried out the comprehensive underwater inspection of the DolWin Gamma converter station in June 2020, under the commission of GE Grid GmbH.

In May 2020, b.offshore received the order to design, manufacture and installation of an mobile heavy duty lifting system for the installation of the container system (modular living quarters) at BorWin Beta OSS from ELA Container Offshore GmbH.

In addition to the design, documentation and manufacturing of the assembly concept including the structural calculation, b.offshore has executed the offshore installation of the container system.

b.offshore has recently been awarded a contract for the supply of a temporary power supply (TPS) system for offshore wind energy installation for the duration of the construction phase. The contract was awarded by Yunneng Wind Power Co., Ltd for the Taiwanese “Yunlin” offshore wind park, located approximately 8 km off the westcoast of Taiwan, boasting 80 wind turbines in the 8 MW class for a combined total of 640 MW. The water depth for the monopile foundations ranges from 8.5 m to 38 m.

In June 2019, the surveying experts of b.offshore GmbH were commissioned to retrofit a rotor hub mounting device at the new production site of the Siemens Gamesa offshore wind turbines in Cuxhaven. On site, a frame for rotor assembly was measured, rebuilt and aligned.

In the spring of 2019, b.offshore GmbH installed an industrial floor in the protection and control room as well as in the operating area of the 220-kV HV room on the OSS Wikinger. Despite bad weather conditions, the daily transfer of passengers and material from Sassnitz to the offshore construction site via CTV transport ship was successful.

In 2018, b.offshore GmbH measured the helicopter landing decks at some offshore substations in the North Sea. In February 2019, the helideck of the Tennet converter platform HelWin alpha was added, which is located north of Helgoland.

At the beginning of the year, b.offshore GmbH looks back on the last almost thirteen months and dares to look ahead to the just started year 2019. On its own or with competent partner companies as in the main focus with the structural design engineers of JÖRSS - BLUNCK - ORDEMANN GmbH (JBO) b.offshore also faces big tasks relaxed. Already in 2018, after numerous success stories in the North and Baltic Seas, the North German company was able to set sail for Asia.

Room air-tightness tests for extinguishing gas systems (also known as Door Fan Tests) have been routine practice in the area of building engineering for a long time. b.offshore GmbH has now carried out such a test for the first time for approximately twenty rooms of an offshore converter station in the North Sea belonging to TenneT.

b.offshore GmbH has successfully completed maintenance work on the substation at Germany's first offshore wind farm alpha ventus, which was built in 2008.
