This paper focuses on the benefits with using electrically powered drilling equipment compared with hydraulically solutions in cold and harsh environments. Improved operational performance with higher availability of the equipment, easier installation and maintenance as well as health, safety and environmental (HSE) issues will be discussed. The paper will especially focus on permanent magnet motor (PM-motor) technology, which has recently been introduced in lifting applications and in larger drilling machinery. The possibilities when designing a PM-motor application is related to reduced size and optimized shape of equipment, as well as an enhanced safety aspect in lifting operations.
