中国石化新闻网讯 瑞士-瑞典技术跨国公司ABB完成了一项3000小时的浅水测试，证明其用于海上油气行业的海底电力分配和转换技术系统在商业上是可行的。 该技术将允许能源公司使用一根电缆，在长达30年的时间里，只需很少或根本不需要维护，就可以在600公里的距离和3000米深的水下接入100兆瓦的电力供应。 整个系统整合了许多电子和控制系统，这些系统已经被证明可以在水下工作，改进了之前只能使用降压变压器和传输电缆的技术。 根据ABB的说法，这项技术可以通过为靠近储层的海床上的泵和压缩机提供动力，显著降低油气作业的电力消耗。 这些节能措施还将减少海上作业的碳排放，未来与可再生能源的整合可以进一步减少碳排放。芬兰瓦萨的浅层试验项目也使用了一种系统来回收自身的废热，回收了85%-90%的废热。 根据一个具体的油田开发案例，该技术可以通过一条电缆连接八个水泵或耗电器材，为海油气公司节省逾5亿美元的资本支出。 该系统是ABB公司与挪威石油天然气公司Equinor于2013年发起的一个价值1亿美元的联合工业项目（JIP）的一部分进行研究、设计和开发的，道达尔和雪佛龙是该项目的合作者。 ABB告诉Offshore Technology，该系统最早将于2020年第一季度投入使用，但可能需要12个月的进一步研究，以获得行政或法律批准。 赵斌 摘译自 离岸技术新闻 原文如下： ABB proves subsea power system for offshore oil and gas Swiss-Swedish technology multinational ABB has completed a 3,000-hour shallow water test proving that its subsea power distribution and conversion technology system for the offshore oil and gas industry is commercially viable. The technology will allow energy companies to access a 100 MW power supply over distances up to 600km and to water depths of 3,000m using a single cable with little or no maintenance for up to 30 years. The complete system incorporates a number of electronics and control systems that are proven to operate underwater, improving on previous iterations of the technology that could only use a step-down transformer and a transmission cable. According to ABB, this technology could significantly reduce power consumption in oil and gas operations by powering pumps and compressors on the seabed, closer to reservoirs. These energy savings would also reduce carbon emissions from offshore operations, which could be reduced further through future integrations with renewable energy sources. The shallow test project in Vaasa, Finland also used a system to recycle its own waste heat as power, reusing 85%-90% of its waste heat. Based on a specific field development case, the technology could offer offshore oil and gas companies capital expenditure savings of more than $500m by linking eight pumps or consumers through a single cable. The system was researched, designed and developed as part of a $100m joint industry project (JIP) initiated in 2013 between ABB and Norwegian oil and gas company Equinor, with Total and Chevron as partners. ABB told Offshore Technology that the system is ready to be deployed as early as the first quarter of 2020, but will likely be subject to 12 months of further study to account for administrative or legal approval.
