Abstract Electric submersible pumps (ESPs) using permanent magnet motors (PMMs) play a key role in lowering the cost of operations and reducing carbon footprint by reducing power consumption by 15 to 20%. As the use of PMMs becomes more prevalent, concerns about PMM safety are rising, especially during the installation and pull of the ESP system; hence, an automated method to monitor PMMs to safeguard personnel is essential. The ESP continuous deployment monitoring system (CDMS) prevents field personnel's exposure to electrical shock by acquiring and logging valuable downhole and surface measurements while installing or retrieving ESP systems. This tool both maintains the ESP system's electrical integrity and implements the two most important components of HSE: risk elimination and engineering control. Additionally, the device can alert the presence of any back electromotive force (BEMF) that may be generated. This system provides the ability to log the resistances between phases, between phase to ground, and downhole sensor readings without any physical contact with the ESP cable. In addition, this tool maintains the three phases of the ESP cable in short condition, reducing the chance of unplanned motor spinning. It also measures the ESP installation or retrieval operational efficiency. It eliminates the need to stop the operation regularly to measure the integrity of the ESP system. The CDMS is not intended to replace other safety considerations or procedures, but rather to complement them. This paper will illustrate the potential electrical hazards and the measures taken to ensure a safe ESP installation and retrieval during field tests and trials.
