About this course

This one-day course provides refresher training for holders of an in-date, OPITO-approved BOSIET or TBOSIET, or FOET or TFOET certificate. 

The training covers the requirements for areas of offshore activities where Compressed Air Emergency Breathing Systems (CAEBS) are in use, inclusive Escape Chute Training (ECT) meets mandatory or company specific training requirements with this safety equipment. The combined training program is fully approved by OPITO with supporting certification (see below) and both accredited to their Vantage database upon successful completion. 

Note: the maximum interval between the successful completion of BOSIET training and subsequent completion of FOET training is four years. Continuation training may be undertaken 90 days prior to the expiry date of existing certification. OPITO has authorised a 'renewal' window prior to a current certificate expiry date for any OPITO-approved 'further' (refresher) training course to be completed without being time-penalised. 

View the dispensation rules if your BOSIET or FOET certificate has expired.

You will be eligible to receive a 10% discount against the cost of a Minimum Industry Safety Training (MIST) course when purchased at the same time as either Further Offshore Emergency Training (FOET) with Emergency Breathing System (EBS) and Escape Chute Training or Further Offshore Emergency Training with CAEBS and Escape Chute Training.

What you'll learn

The combined course consists of two OPITO-approved training programmes: 

Further Offshore Emergency Training (FOET) with CAEBS – complements and refreshes existing emergency training, updating and reinforcing the knowledge gained on the BOSIET course with regard to helicopter underwater escape training (HUET), use of CAEBS and sea survival techniques, emergency first aid, fire fighting and self-rescue techniques using smoke hoods. 
This programmed is designed to meet the further offshore safety and emergency response training requirements for personnel working in the offshore oil and gas industry. Certification is issued with a four-year validity period. 
Escape Chute Training (ECT) – introduces or refreshes both theoretical knowledge and practical exercises in the safe use of escape chutes increasingly used on offshore installations and vessels. Certification is valid for four years from the date of issue.  

Escape chute training is an additional module developed by OPITO and acceptable under the Mutual Recognition of Basic and Refresher Safety and Emergency Preparedness Training agreement between Oil and Gas UK, Norsk olje og gass (Norway), Olie Gas Danmark (Denmark) and NOGEPA (Netherlands). 

The Mutual Recognition document has been in effect since November 2007 and was revised in September 2014 to continue harmonising offshore survival training standards within sectors of the European North Sea. The course will satisfy the offshore survival training requirements for personnel intending to work in European sectors requiring compressed air emergency breathing systems (CAEBS). For European sectors not using CA-EBS please refer to the Mutual Recognition document to determine course applicability. 

See our Further Offshore Emergency Training & Escape Chute Training course if you require emergency breathing system training (currently used in many areas of offshore activity outside UK and Dutch North Sea Sectors). 


OPITO require delegates to participate in CA-EBS In Water Training (IWT) exercises. As a result, delegates undertaking OPITO BOSIET/HUET/FOET with CAEBS courses will have to provide both the following at the point of enrolment: 

  1. Valid OGUK Medical/or valid Offshore medical issued by a body outside of the UK (recognisedas equivalent to the OGUK). Other medical certificates recognised by the Diving at Work Regulations 1997 exemption DWR/1 of 2018 as being equivalent to an Oil and Gas UK Offshore medical certificate are: 
  • Netherlands Oil and Gas Exploration and Production Association Medical 
  • Norwegian Directorate of Health (Petroleum Sector medical) 


  1. A ‘Fit’ or ‘Unfit’ to undertake shallow water CA-EBS training certificate issued by a registered OGUK examiner. This should have been done within the lifespan of the current offshore medical.

IMPORTANT INFORMATION: If you possess a valid and current UK ENG1 Seafarers Medical (or a recognised equivalent seafarers medical, as listed in MSN1815) or HSE certificate of medical fitness provided by an Approved Medical Examiner of Diving (AMED) you will not be required to undertake 1) and 2) above, as you have already met the requirements of the Diving at Work Regulations 1997. Delegates must bring their ENG 1 (or equivalent seafarers medical) or HSE dive medical (as above) to course enrolment on day one. For guidance regarding HSE website diving medicals, please refer to the HSE website.   

The above does not apply to delegates completing courses with LAPS rebreather.

PLEASE NOTE: Global Wind Organisation (GWO)/Renewable UK (RUK) Wind Turbine medicals (for example) do not meet the requirements of the HSE Diving at Work exemption for CA-EBS in-water training and therefore cannot be accepted as a pre-requisite for this course.
