There are many types of job on an oil platform. Some of them require a degree and others are more physical.
Cathy is one of the women on the platform.
Engineers. The Captain platform has two engineers. Udeni, the production engineer, maximises the output from the wells. Cathy, the process engineer, looks after the equipment that separates the crude mixture.
Chemist. There is a resident chemist on most platforms. The chemist will test samples of the crude oil mixture from the wells to help develop and optimise ways of treating it.
