With the increasing interest in a green transition to Net Zero, offshore renewable energy is becoming a big focus for many countries. There are hundreds of offshore wind turbines which are coming to the end of their 25-30-year lifecycle and many developers are looking into life extension options to maximise their assets. The structures for offshore renewables are subject to some of the harshest environments in the world, with loading from wind, wave, and tides in a corrosive and erosive environment. Additive Manufacturing (AM) has shown great promise for use in the marine environment. However, little research or application of the technology has been done within the sector. Corrosion is seen as one of the biggest threats to offshore structures and can be accelerated with the presence of erosion. AM has the potential to mix different materials to improve the properties of the end part. Wire Arc Additive Manufacturing (WAAM) has shown great promise due to the ability to create large components, in short lead times, with little defects compared to traditional manufacturing processes. The process allows for easy manufacture at ports or yards near offshore sites and therefore has the potential to create components with shorter lead times compared to traditional supply chain routes. Early research into the potential of using WAAM to create corrosion resistance coatings and components has highlighted the processes' many benefits but further research is required to justify the use of the processes for commercial applications. In terms of wear resistance even less research has been conducted but initial findings show that there is a greater resistance compared to the wrought material. The aim of this study is to thoroughly review the state-of-the-art on the use of AM for erosion and corrosion resistance of engineering structures with the focus on offshore renewable energy structures. The findings from this study help to identify the gap in the knowledge for future research to commercialise the AM application within the offshore industry.

随着人们对向净零排放的绿色过渡越来越感兴趣，海上可再生能源正成为许多国家的一大关注点。数以百计的海上风力涡轮机的25-30年生命周期即将结束，许多开发商正在寻找延长寿命的选择，以最大化他们的资产。海上可再生能源的结构受到世界上一些最恶劣的环境的影响，风、浪和潮汐在腐蚀性和侵蚀性的环境中加载。添加剂制造(AM)在海洋环境中的应用前景广阔。然而，该行业内对该技术的研究或应用很少。腐蚀被认为是对近海结构的最大威胁之一，腐蚀的存在可能会加速腐蚀。AM有可能混合不同的材料来改善末端部件的性能。焊丝电弧添加剂制造(WAAM)显示出巨大的前景，因为与传统制造工艺相比，WAAM能够在较短的交货期内生产出几乎没有缺陷的大型部件。该工艺允许在离岸地点附近的港口或船厂轻松制造，因此与传统供应链路线相比，有可能制造出交货期更短的零部件。对使用WAAM制造耐腐蚀涂层和组件的潜力的早期研究突出了该工艺的许多好处，但还需要进一步的研究来证明该工艺用于商业应用的合理性。在耐磨性方面，进行的研究更少，但初步研究结果表明，与锻造材料相比，耐磨性更强。这项研究的目的是对AM用于工程结构耐冲刷和腐蚀的最新技术进行全面综述，重点是近海可再生能源结构。这项研究的结果有助于确定知识的差距，以便未来研究在离岸行业内将AM应用商业化。
