Relative position referencing goes without targets
Dynamic Positioning | Standard microwave position reference sensors used in the offshore oil and gas industry are not optimised for positioning inside a wind farm. Whereas a platform supply vessel in the oil and gas industry may support just two to three platforms, a wind farm service and operations vessel supports as many as 150 wind turbines, each with up to three approach angles. The following article discusses RangeGuard Monopole DP, the first local DP reference sensor system for offshore wind farms that operates without dedicated targets. The latest results from the first fully integrated system on the service operation vessel (SOV) Windea La Cour are presented by Andy Knight and Sasha Heriot from UK-based Guidance Marine, and Hendrik Busshoff from Germany’s Bernhard Schulte Ship Management GmbH & Co KG. This article is a follow-up of a previous paper, “A new era in local position referencing”, which was published in Ship&Offshore 05|2016.
