FIGURE 3. Integrated operation - solution pattern overviewIt is clear that there are no energy industry, there<strong>for</strong>e we will drop them in the further discussion. Operation and maintenance is animportant part in oil and gas industry as well as in wind energy industry. M&O costs <strong>of</strong> <strong>of</strong>fshore windfarms contribute substantially (25-30%) to the energy generation costs (Hassan et al., 2001; Pieterman etal., 2009).In the third part, instead <strong>of</strong> existing applications, we have some applications from <strong>of</strong>fshore wind partners,<strong>for</strong> instance, wind turbines control and modeling system, weather <strong>for</strong>ecast monitoring system,engineering systems, asset management, wind farm modeling and control, energy market monitoring. Inthis paper we focus on the second part <strong>of</strong> the IT architecture. Be<strong>for</strong>e going into more detail on each layer<strong>of</strong> the second part, we take a look at the solution pattern overview <strong>of</strong> remote operations, a modifiedarchitecture from IO as shown in FIGURE 4 below.ProductionManagementOperation andMaintenanceServices PatternSemantic ModelIntegration Pattern<strong>Wind</strong> farmmodeling &control<strong>Wind</strong>turbinecontrol &modelingWeather<strong>for</strong>ecastmonitoringsystemEnergymarketmonitoringEngineeringsystemsMaintenance& AssetManagementEquipment &ProcessDocumentation...PROCESS CONTROL DOMAINENTERPRISE DOMAINFIGURE 4. <strong>Remote</strong> operations - solution pattern overview3.1 Semantic modelIn this model, we describe how data will be integrated in <strong>of</strong>fshore wind energy industry. How can wemanage the fact that in wind energy industry data comes from different sources with different <strong>for</strong>mats?Based on IO and a variety <strong>of</strong> practical experiences we conclude that an implementation <strong>of</strong> semantictechnology in the reference architecture is a good solution.Page 1055
