Work experience
Wei Zhao embarked on his professional journey as a Process Equipment Engineer in a refinery immediately after completing his bachelor's degree in 2010. In this role, his primary responsibilities encompassed the installation, operation, and maintenance of process equipment employed within the oil refinery setting. Notably, he gained expertise in handling various types of equipment, including Centrifugal and Reciprocating pumps, Gas and Air Compressors, Steam Turbines, and Flow Control Valves.
In 2016, Wei Zhao undertook a three-month internship as a Workshop Technician. During this period, his primary responsibilities involved the redressing and fault analysis of well service tools such as Tractors, Strokers, Well Keys, and other related equipment.
Following the completion of his master's degree in 2019, Wei Zhao joined Cameron Sense AS, where he assumed the role of a Technical Support Engineer with a specialization in control systems. In this capacity, his main responsibilities encompassed providing Ontrack24 technical support for drilling control systems, as well as carrying out Site Acceptance Tests (SAT) and Factory Acceptance Tests (FAT).
Projects
Wei Zhao's PhD project titled "Development of Energy-Efficient Linear Actuation Systems for Offshore Use" was funded by the Research Council of Norway, SFI Offshore Mechatronics, project number 237896/O30.
