北海方面石油和天然气的开发给于电工生产多方面的任务。首先是近海岸钻井台的电气设备,其次是陆上基地的电气设备,此外基地的生活建筑和钻井台的附属设备都需要用电。 在发展北海石油和天然气的大量投资中,用于电气设备的比例是很小的。预测在英国范围区内从现在到1985年每年平均投资额约2.5亿英磅,其中约有7百万英磅用于钻井台的发电设备。据另一个分析,在4千万英磅钻井台的总投资中,约有1百万英磅用于发电设备,1百万英磅用于开关配电设备,50万英磅用于电讯系统。这里不包括钻机直接的用电设备和生活用电设备。当然,这种分析不是一个标准,钻井台有大小,有深浅,深水钻井台的总投资要高。北海其他国家范围区从现在到1985年的总投资估计为2亿英 The development of oil and natural gas in the North Sea has given electricians a variety of tasks. The first is the electrical equipment of offshore drilling rigs, followed by the electrical equipment of the land-based bases. In addition, the living buildings of the base and the auxiliary equipment of the rigs need electricity. In the large investment in the development of oil and gas in the North Sea, the proportion of electrical equipment used is small. It is estimated that the average investment in the UK area from now to 1985 will be approximately 250 million pounds per year, of which approximately 7 million pounds will be used for power generation equipment on the rig. According to another analysis, of the total investment of 40 million pounds of rigs, approximately 1 million pounds were used for power generation equipment, 1 million pounds was used to switch power distribution equipment, and 500,000 pounds was used for telecommunications systems. . This does not include rigs directly using electricity equipment and household electrical equipment. Of course, this kind of analysis is not a standard. The size and depth of a drilling rig is very high. The total investment for deep-water drilling rigs is high. Estimated total investment from now to 1985 in other countries in the North Sea is 200 million British
