第一个海上海洋热能转换（OTEC）电源由Mini-OTEC于1979年8月2日生产。该动力装置安装在一艘驳船上，该驳船位于距离夏威夷科纳海岸Keahole Point约2.2 km处。氨被用作封闭循环（朗肯）动力装置的工作流体，该动力装置在平均海水温差为21°C的情况下产生约50千瓦的总电力。海水和氨的寄生泵送功率要求导致净电力约为15千瓦。通过直径为0.61 m的聚乙烯管从约670 m的深度抽取冷海水，该聚乙烯管构成单点张力腿系泊系统的一部分。最长的连续运行时间为10天，于1979年11月18日结束。
The first at-sea ocean thermal energy conversion (OTEC) power was produced by Mini-OTEC on Aug. 2, 1979. The powerplant was mounted on a barge located approximately 2.2 km off Keahole Point on the Kona Coast of Hawaii. Ammonia was employed as the working fluid in a closed-cycle (Rankine) powerplant, which produced approximately 50 kW of gross electrical power at an average seawater temperature difference of 21°C. Parasitic pumping power requirements for seawater and ammonia resulted in a net electrical power of approximately 15 kW. Cold seawater was drawn from a depth of approximately 670 m through a 0.61 m dia polyethylene pipe, which formed part of a single-point tension leg mooring system. The longest period of continuous operation was 10 days, terminated by the conclusion of the program on Nov. 18, 1979.
