The energetics of large amplitude, high-frequency nonlinear internal waves (NLIWs) observed over the New Jersey continental shelf are summarized from ship and mooring data acquired in August 2006. NLIW energy was typically on the order of 105 Jm−1, and the wave dissipative loss was near 50 W m−1. However, wave energies (dissipations) were ∼10 (∼2) times greater than these values during a partic...

This research proposes the design of a mooring system that allows floating platform to stably dive deep enough prevent damage induced by typhoon waves. The principle mechanism is submarined with negative buoyancy connected pontoon positive buoyancy. diving depth determined rope length. If static equilibrium two forces satisfied, will be kept. enough, not directly damaged wave impact. In reality...

In this study, the problems of diffraction and radiation water waves by a permeable vertical cylindrical body are formulated within realm linear potential theory. The body, which is floating in constant depth, moored with catenary mooring line system. method matched eigenfunction expansions for prediction velocity fluid domain surrounding applied. Furthermore, static dynamic characteristics sys...

Abstract Floating wind farms present the opportunity to harvest resources located in deep water sites. Shared mooring designs can contribute making floating energy more cost-competitive, and it is important understand new system dynamics that arise. We are presenting here HAWC2Farm, an extension of HAWC2 model multiple turbines with shared lines. apply modeling capabilities simulate two 15 MW o...

Real-time monitoring of the mooring safety floating structures is great significance to their production operations. A deep learning model proposed here, based on long short-term memory (LSTM) artificial neural network. Firstly, numerical simulation carried out with single-point system a Floating Production Storage and Offloading (FPSO) as training data LSTM. Then LSTM performed. Finally, takin...
