.... Then, the prediction and diagnostic analysis of the degradation process are carried out according to the dynamic Bayesian networks inference. The recovery process includes three stages: fault diagnosis, resource allocation and maintenance. To model the recovery process, a new DBN model is established by integrating...

..., with private initiative and public incentives over the value chain of FOWT (design manufacturing, installation, operation, and maintenance) and the linkage of such a new concept in the established energy matrix. On the other hand, aspects overseen earlier are now real challenges. The commercial profitability...

... ABSTRACT Operation and maintenance (O&M) costs constitute the biggest share (more than 30%) of lifecycle cost for offshore wind energy, indicating enormous costs are expected to be invested in O&M in the near future along with the increasing operational capacity all over the world...

... ABSTRACT With renewable energy development, the offshore wind turbine is playing a more critical role in ocean engineering. The operation and maintenance (O&M) of the offshore wind turbine consumes a large percentage of cost in the whole life of the offshore wind project. In the O&M...

... system operational maintenance safety and fault diagnosis have become increasingly important. In the field of data analysis, it was believed that equipment failures were usually reflected in the time-domain and frequency-domain (Gao, 2018), in varying degrees, suggesting some internal connection between...

... wind turbines to harness the great wind resources often found at deeper waters. Installation and maintenance of large floating wind turbines by crane ships is currently a main cost driver. The availability of such large crane ships as well as suitable weather windows for their operation at windy...

... Abstract The mobile production and storage platform with subsea mat oil tank is an important platform form for "BEE Mode" of marginal oilfield development. The calculation of temperature drop and maintenance for subsea oil storage tank is very important, especially for the crude oil with high...

... ABSTRACT This paper addresses challenges in fatigue management of marine structural assets with a holistically approach, by jointly considering fatigue design, inspection and maintenance decisions, whilst taking into account sources of uncertainties affecting life cycle performance. A risk...

... such as wind and waves. The motion response increases when moving from fixed-bottom to floating substructure concepts - a finding that has initiated a large research study to investigate if the well-being of humans located on floating platforms during maintenance work could potentially be affected. This paper...
