What else do I need to work offshore?

As well as making sure you have the best training to get your new career in the subsea industry off to a flying start, what additional certificates and medicals will you need to be able to work offshore?

Offshore Survival CourseJack up Rig
The Offshore Survival Course for UK waters is officially known as Basic Offshore Safety Induction and Emergency Training, or BOSIET.  It includes a range of skills which may be required when working offshore including safety, first aid and hypothermia, fire prevention and fire fighting, helicopter safety and escape and survival at sea.

The course to allow you to work in UK waters usually takes up to three days to complete and costs around £600.  The certificate is valid for 4 years with a refresher required before the expiry of the old certificate.  The refresher usually only takes about a day to complete.

Outwith the UK, other countries operate different requirements and it is worth ensuring you attend and pay for the relevant course, depending on where you are going to be working.  For example, the Norwegian sector of the North Sea requires you to complete a three and a half day course.  There is also a tropical version of BOSIET which covers the dangers of such waters.

Having the BOSIET certificate will certainly help in your job application and search, as it ticks a box for potential employers.  However, it by no means guarantees you a job offshore.  Occasionally, some companies will also pay for you to complete it before starting work with them.   You can get a list of OPITO approved providers of the BOSIET course here.  (OPITO exist to ensure a competent and safe workforce supply for industry.)

Offshore Medical
Everyone that works offshore is also required to complete a medical.  If you are a commercial diver, your Diving Medical (renewed annually) will cover this as it is much more extensive than the standard offshore medical.

For everyone else, including ROV Pilot Technicians and Assistant Life Support Technicians, the OGUK Offshore Medical is required to work in UK waters. This medical needs to be renewed after 2 years.  Requirements when working in other countries may vary.

Only physicians registered and approved by OGUK can carry out offshore medicals.  Prices vary depending on the practice, but are generally around £110.  Ask for the Norwegian Medical at the same time as many practitioners will generally include this free of charge or will just charge a nominal fee.

Minimum Industry Safety Training (MIST) Certificate

If you are platform based you may also require a MIST certificate; some companies ask for this regardless of where you will be based, in case plans change mid-contract.  Most training providers that provide the BOSIET training mentioned earlier can also provide the MIST training; you can get a list of OPITO approved MIST training providers here.  The MIST training costs around £300 and a refresher is required every 4 years.
