自上个世纪以来，海上能源生产一直是北海的一个新兴产业，随着可再生能源替代品的日益发展，未来可能会变得更加重要。负责收集和生产能源的平台在大多数基质柔软的区域提供了坚硬的基质，为污垢群落建立了栖息地，并在其上定居和生长。随着时间的推移，这些群落开始给能源生产公司带来问题，因为它们的生物量自然增加可能会对平台基础构成风险，导致必须进行定期检查，以使装置能够保持正常工作。为了解决这个问题，并更好地了解如何清洁工作可以直接，创建一个模型，这些污垢社区的增长与不同的环境变量。测试的变量涉及海面盐度和温度、海底地形、到海岸的距离、深度、海流和风速、鱼类丰度、悬浮颗粒物和叶绿素的浓度以及是否有人工结构。研究结果表明，深度和叶绿素浓度是影响污损生物群落生物量变化的主要因素。
Offshore energy production has been a rising industry in the North Sea since the past century and will likely gain more importance in the future with the increasing development of renewable alternatives. The platforms that are responsible for harvesting and producing energy provide a hard substrate in areas where most substrate is soft, establishing a habitat for fouling communities to settle and to grow on. With time, these communities start to compose a problem for energy production companies, as their natural increase in biomass may pose risks to the platform foundations, leading to the necessity of performing regular inspection so the installations can keep working properly. To address this issue and to better understand how cleaning efforts can be directed, a model was created to relate the growth of these fouling communities with different environmental variables. The variables tested were related to sea surface salinity and temperature, seafloor topography, distance to shore, depth, current and wind velocity, fish abundance, concentration of suspended particulate matter and chlorophyll and presence or absence of artificial structures. Our results indicated that depth and chlorophyll concentration in the water column where the main factors affecting biomass variations in fouling communities.
