This paper discusses trends in condition monitoring of modern offshore wind turbines. First an overview is given of design changes that have been made over the years to large offshore wind turbines and how this resulted in novel opportunities from a monitoring perspective. Similarly, the evolution in data source availability is discussed. From these opportunities, some ongoing research activities in the field are discussed and how they fit with the open challenges. This list is far from exhaustive. It gives an overview of some capita selecta. Particularly, the fields of advanced signal processing and requirement for innovations towards prognostic frameworks are highlighted.

本文讨论了现代海上风机状态监测的趋势。首先，概述了多年来对大型海上风力涡轮机进行的设计更改，以及从监控的角度来看，这是如何带来新机遇的。同样，讨论了数据源可用性的演变。从这些机会中，讨论了该领域中一些正在进行的研究活动，以及它们如何适应公开挑战。此列表远非详尽无遗。它提供了一些人均选择的概述。特别是，重点介绍了高级信号处理领域以及对预后框架进行创新的需求。
