Design, modelling, and analysis of a large floating dock for spar floating wind turbine installation

2020

Installation of floating wind turbines at the offshore site is a challenging task. A significant part of the time efficiency and costs are related to the installation methods which are sensitive to weather conditions. This study investigates a large floating dock concept, which can be used to shield a floating wind turbine during installation of tower, nacelle, and rotor onto a spar foundation. In this paper, the concept is described in detail, and a design optimisation is carried out using simple design constraints. Hydrodynamic analysis and dynamic response analysis of the coupled system of the optimum dock and spar are conducted. Two spars of different sizes are considered, and the motio…

Toward farm-level health management of wind turbine systems: status and scope for improvements

2018

An outline of health management for OWFs has been detailed in this chapter with description of various important elements. The need for such farm level management is explained and benefits are discussed. Key gaps to be filled in order to realize such a system are identified. The proposed health management system is mainly based on the existing knowledge of fleet-level management in the aerospace sector. Health management is much broader than CM; there are a number of aspects beyond the prognostics capabilities that are to be designed in order to arrive at a comprehensive maintenance management scheme. A comprehensive maintenance program that is sensitive to the health of the assets and adap…

Marine Discharges of Offshore Produced Water: the North-East Atlantic Management Strategy

2002

Este capítulo contiene un estudio de Derecho internacional del medio ambiente sobre las normas y estrategias para prevenir y eliminar la contaminación resultante de hidrocarburos y otras substancias causadas por las descargas de agua de producción costa afuera en el mar. Debemos tener en cuenta que no existe ni un solo tratado internacional de ámbito mundial relativo a la contaminación por descargas de hidrocarburos contenidas en las aguas de producción generadas en las instalaciones costa afuera. De hecho, sólo hay una región marina donde existen normas jurídicas y estrategias para hacer frente a este problema de contaminación. La región marina es el Atlántico nordeste y la norma en cuesti…
