Regional heavy rainfall events (RHREs) have shown an increasing trend in Guangdong Province, South China, in recent decades. In order to retrieve a reliable evaluation of the RHREs in this region, this paper proposes an improved method for assessing the overall strength of each RHRE and a workflow for recognising its spatial distribution pattern. Following the identification criteria of China's national standard, 1537 RHREs we...

The condition of an offshore wind turbine (OWT) should be monitored to assure its reliability against various environmental loads and affections. The modal parameters of the OWT can be used as an indicator of its condition. This paper combines the Kalman filter, the random decrement technique (RDT), and the stochastic subspace identification (SSI) methods and proposes an RDT-SSI method to estimate the operational frequency of...

Ice-induced vibration is one of the major risks that face the offshore platform located in cold regions. In this paper, the gated recurrent neural network (GRNN) is utilized to predict and suppress the response of offshore platforms subjected to ice load. First, a simplified model of the offshore platform is derived and validated based on the finite element model (FEM). The time history of the floating ice load is generated us...
