About this course

This course is designed for new entrants to the offshore oil and gas industry in the areas of offshore activity using compressed air emergency breathing systems (CAEBS) (see note below). Most offshore oil and gas installations, wind farm and vessel operators require their employees, contractors and, in some cases, even visitors to undertake this training prior to travelling offshore.  

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 the Vantage database upon successful completion.  

You will be eligible to receive a 10% discount against the cost of a MIST (Minimum Industry Safety Training) course when purchased at the same time as either BOSIET with Escape Chute Training or BOSIET with CAEBS and Escape Chute Training. Please email to request a one-time discount code before you book online.

Certificate extension policy

In March 2020, OPITO implemented a certificate extension process to support those impacted by the Covid-19 pandemic. This process was originally scheduled to draw to a close on 1 May 2021. However, as situations continue to evolve in certain regions, OPITO has decided to continue to offer support for submitted certificate extensions - this is assuming they continue to be submitted in line with the exceptional eligibility criteria detailed in the current policy. The process, therefore, did not cease on 1 May 2021 and advanced warning of support being withdrawn will be communicated in due course and when suitable. More information can be found here.

What you'll learn

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

Basic Offshore Safety Induction and Emergency Training (BOSIET) provides students with a basic understanding and awareness of the hazards encountered during travel to offshore installations and the emergency procedures to be followed in the event of an offshore incident. The training is based on four modules: 

  • Safety induction
  • Sea survival (including first aid)
  • Fire fighting and self-rescue
  • Helicopter safety and escape training including HUET (helicopter underwater escape training) with CA-EBS. 

This training provides students with a basic understanding and awareness of the hazards encountered during travel to offshore installations and the emergency procedures to be followed in the event of an offshore incident. Certification is valid for four years from the date of issue. 

Escape chute training - introduces 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 CAEBS please refer to the Mutual Recognition document to determine course applicability. 

See our Basic Offshore Safety Induction and Emergency Training with 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 OEUK (formerly OGUK) Medical/or valid Offshore medical issued by a body outside of the UK (recognised as equivalent to the OEUK). 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 OEUK (formerly 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 approved 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.

Please see our Covid-19 statement and guidance for those attending maritime training and certification courses and exams at Warsash Maritime School and Solent University.
