项目摘要

Permanent offshore structures form artificial reefs which provide attachment and settlement sites for marine organisms. In the UK, some of the oldest platforms have been in the water for over 40 years and have considerable colonisation of marine organisms. Marine Growth organisms generally include seaweeds, soft corals and mussels in the areas where light penetrates(photic zone) as well as anemones, hydroids and cold-water corals on the deeper sections of the platforms. One of the first marine growth studies published was on the Montrose platform back in 1982; and significant discoveries have been made during offshore installation marine growth assessments since then, such as the first discovery of the CITES Listed Lophelia pertusa coral growing on offshore platforms during the decommissioning of the Brent Spar storage buoy, the with results subsequently being published in Nature in 1999. L. pertusa as since been recorded on the majority of northern North Sea platforms - and therefore their presence on the structures may be contributing to the connectivity of the protect reefs in the UK and Norway.Marine growth causes issues for the oil and gas industry (operators) by adding additional weight to the structure which may cause damage and impair visual inspection of important equipment, both in routine and decommissioning scenarios. New areas of interest have also developed around platform marine growth, including the potential for marine invasive species, potential "stepping stone" habitats, artificial reefs for conservation (e.g. de-facto MPAs) or fish using the structures for food and shelter. In areas of the Gulf of Mexico, a "rigs-to-reef programme", (the conversion of offshore platforms into designated artificial reefs) is underway. However, in Europe, particularly in the North East Atlantic OSPAR region, there is a requirement to remove all offshore infrastructures from the seabed (although derogations may be granted). As part of the decommissioning plan, an operator may be required to assess the extent of marine growth on a platform to determine the additional weight added to the platform (for structure removal) or for potential organic waste disposal and especially if species of conservation importance (e.g. Lophelia and Sabellaria) are present. This project will use a pre-devolved method (CoralNet) to analysis images of marine growth on offshore structures. The method will allow for more images to be analysed, compared to traditional assessment methodology and will allow for a more consistent approach, potentially providing for a good long-term monitoring tool. In addition, finding new and innovative monitoring methods, is not only about collecting data in the field, but also about how the data should be analysed, with this project will contribute.

永久性离岸建筑物形成人工鱼礁，为海洋生物提供附着和定居点。在英国，一些最古老的平台已经在水中存在了40多年，并且有相当多的海洋生物定居。海洋生长生物通常包括海藻，软珊瑚和贻贝在光穿透的区域（透光区）以及海葵，水螅和冷水珊瑚在平台的较深部分。早在1982年就发表了关于蒙特罗斯平台的首批海洋生长研究报告;此后在海上安装海洋生长评估期间取得了重大发现，例如在布伦特Spar储存浮标退役期间首次发现了生长在海上平台上的CITES上市的Lophelia pertusa珊瑚，其结果随后于1999年发表在Nature上。L.此后，北海北方大部分平台上都记录了pertusa，因此它们在结构上的存在可能有助于英国和挪威保护礁的连通性。海洋生长给石油和天然气行业（运营商）带来了问题，因为增加了额外的重量结构可能会导致损坏并损害重要设备的目视检查，无论是在常规情况下还是在退役情况下。围绕平台海洋生物还开发了新的关注领域，包括海洋入侵物种的潜力、潜在的“垫脚石”生境、用于保护的人工礁（例如事实上的海洋保护区）或利用结构作为食物和住所的鱼类。在墨西哥湾地区，正在实施“钻机转礁方案”（将近海平台改造成指定的人工礁）。然而，在欧洲，特别是在东北大西洋保护东北大西洋海洋环境公约区域，有一项要求是将所有岸外基础设施从海床上拆除（尽管可能允许例外）。作为退役计划的一部分，可能要求运营商评估平台上海洋生物的范围，以确定增加到平台上的额外重量（用于结构拆除）或潜在的有机废物处置，特别是如果存在重要的保护物种（例如Lophelia和Sabellaria）。该项目将使用一种预先开发的方法（CoralNet）来分析海洋结构物上海洋生物的图像。与传统的评估方法相比，该方法将允许分析更多的图像，并将允许采取更一致的方法，可能提供一个良好的长期监测工具。此外，寻找新的和创新的监测方法，不仅是在实地收集数据，而且是如何分析数据，该项目将作出贡献。
