自二十世纪中叶开始对海洋石油和天然气储量进行商业开采以来，在全球范围内建立了广泛的海上基础设施网络。许多建筑物的使用寿命即将结束，不久将需要退役，这将重新引起人们对它们的环境影响和拆除它们的生态后果的兴趣。然而，这项工作需要选择一小部分资产进行调查；由于人口数量庞大，几乎不可能对任何给定司法管辖区的全部“人口”进行人口普查。因此，重要的是，选定的样本必须充分代表总体，以便得出一般性结论。在这里，一种正式的聚类方法，围绕着中线划分，被用来产生北海穿透水面的油气平台的类型学。用于聚类的变量包括碳氢化合物产品、操作状态、平台设计和材料以及下部结构重量。通过评估组内变异性，确定了13个组为最佳数目。最重要的区分变量是平台类型，首先隔离浮动平台，然后是混凝土重力基础，最后是固定钢。在集群之后，一个明显的地理趋势是，石油生产在北部更普遍，天然气在南部更普遍。该类型学允许在设计调查或评估先前选定的平台子集的代表性时选择具有代表性的北海油气平台子集。这将有助于有效利用可用于这类研究的有限资金。
Since the commercial exploitation of marine oil and gas reserves began in the middle of the twentieth century, extensive networks of offshore infrastructure have been installed globally. Many of the structures are now nearing the end of their operational lives and will soon require decommissioning, generating renewed interest in their environmental impacts and in the ecological consequences of their removal. However, such work requires selection of a subsample of assets for surveying; censuses of the entire ‘population’ in any given jurisdiction are practically impossible due to their sheer number. It is important, therefore, that the selected sample is sufficiently representative of the population to draw generalized conclusions. Here, a formal clustering methodology, partitioning around medoids, was used to produce a typology of surface-piercing oil and gas platforms in the North Sea. The variables used for clustering were hydrocarbon product, operational state, platform design and material, and substructure weight. Assessing intra-cluster variability identified 13 clusters as the optimum number. The most important distinguishing variable was platform type, isolating floating platforms first, then concrete gravity-based and then fixed steel. Following clustering, a geographic trend was evident, with oil production more prevalent in the north and gas in the south. The typology allows a representative subset of North Sea oil and gas platforms to be selected when designing a survey, or an assessment of the representativeness of a previously selected subset of platforms. This will facilitate the efficient use of the limited funding available for such studies.
