In September 2013 we initiated a review to examine the risks and hazards of offshore helicopter
operations in the UK, which was conducted in conjunction with the European Aviation Safety Agency
(EASA) and the Norwegian Civil Aviation Authority. A report of the review was published in February
2014 entitled CAP1145: Safety review of offshore public
transport helicopter operations in support of oil and the exploitation of oil and gas. Two
progress reports to this review have been was published:
The review put forward 32 actions and 29 recommendations to helicopter operators, the oil and
gas industry, manufacturers and EASA which will improve offshore helicopter safety around the
following four main areas:
An action from the review was to set up a CAA-led safety governance body for offshore
operations, with representation from key organisations from across the industry, named the Offshore
Helicopter Safety Action Group (OHSAG).
The primary purpose of the OHSAG is to:
There is a strong collective commitment to deliver positive safety changes by all parties
represented in the OHSAG.
The majority of the actions and recommendations outlined in the Review to improve safety focus
on preventing accidents but some also focus on improving survivability following an incident.
Safety improvements overseen by the group so far include:
Latest progress against delivery of the Review can be found in CAP 1243.

downloadable FAQ sheet on passenger size. Online editions of the ‘Tea Shack News’ publication are

OHSAG is very conscious of workforce concerns over plans to prevent helicopter operators
carrying passengers whose body size means they couldn’t escape through push-out window exits in an
The change is to ensure that everyone on board can escape in the event of a helicopter capsizing
after a ditching or water impact.
The Group’s aim is that no one loses their job as a result of the change. While the
classifications may present some logistical challenges, we believe the implications for those who
travel offshore are manageable within the current helicopter fleet.
Following a study of helicopter exits and of the offshore workforce a shoulder width measurement
of 22” or over will be classified as ‘extra broad’ (XBR). Every offshore worker will be measured.
Step Change has released details of how this measurement will take place. Workers whose shoulder
width exceeds 22” will be classified as extra broad on the Vantage seat booking system. Those
passengers will be allocated a seat which has direct access to the larger Type III and Type IV
window exits. At least 30% of seats on all helicopters fall into this category which we believe is
more than the number of passengers that will be classified as extra broad.
Information on Step Change’s Passenger Size workgroup is available at the Step Change in Safety website.
Since CAP1145: Safety review of offshore public transport
helicopter operations in support of oil and the exploitation of oil and gas was published in
February 2014, several further reports have followed, including:
