为了充分利用测试场地,海洋能源设备开发商必须能够及时且具有成本效益的方式部署、维护和退役其设备。此外,海洋能源行业正在转向阵列部署(DECC,2012 年和 BBC,2012 年),虽然这些部署提供了最大化资源利用同时最小化相关成本(例如部署)的绝佳机会,但以具有成本效益的方式执行所述部署至关重要。对此至关重要的是了解现场的气象海洋条件和天气窗口可用性,特别是当这与船舶可用性和停机成本相结合时。本文提出了一种基于 Weibull 模型的方法,该模型使用超标持续时间的平均持续时间的累积分布(Stallard 等人,2010 年;Walker 等人,2011 年)。所讨论的方法已应用于英格兰西南部的案例研究,使用特定地点的环境参数和经验表达式来计算可访问时间。案例研究的结果用于确定海上作业的可进入时间和等待时间,并就西南波浪中心安装波浪能装置进行了讨论(波浪中心,2010)。
In order to fully utilise test sites, marine energy device developers must be able to deploy, maintain and decommission their equipment in a timely and cost effective manner. In addition, the marine energy industry is moving towards array deployments (DECC, 2012 and BBC, 2012) and whilst these deployments present an excellent opportunity to maximise resource usage whilst minimising the associated costs, for example of deployment, it is essential that said deployment is performed in a cost effective manner. Critical to this is the knowledge of the metocean conditions at the site and the weather window availability, particularly when this is coupled with vessel availability and downtime costs. In this paper a method is presented based on a Weibull model which uses cumulative distributions of the mean duration of persistence of exceedance (Stallard et al., 2010; Walker et al., 2011). The method discussed has been applied in a case study for the South West of England using site specific environmental parameters and empirical expressions to calculate the accessible periods. The outcomes from the case study are applied to identify the accessible periods and the waiting time for marine operations, and a discussion is made regarding the installation of wave energy devices at the south west Wave Hub (Wave Hub, 2010).
