Illnesses which can be easily managed in the urban setting (e.g. an asthmatic attack) may result in a crisis when it occurs at a remote oil and gas facility. To mitigate risks, most offshore operators mandate regular medical assessments on offshore workers. These medical assessments for fitness to work (FTW) are normally conducted face-to-face, at a physician's clinic onshore. They are conducted when the employee has been demobilised from the offshore platform (i.e. during their rest days). Recent technological advances have allowed physicians to conduct FTW assessments remotely using telehealth equipment. This presents oil and gas operators with the opportunity to save on consultation and travel costs, as well as the time taken to pursue an assessment.
