Safety cases

The Offshore Installations (Safety Case) Regulations 2005 (SCR05) and the Offshore Installations (Offshore Safety Directive) (Safety Case etc) Regulations 2015 aim to reduce the risks from major accident hazards to the health and safety of the workforce employed on offshore installations, and in connected activities.

This site helps dutyholders to comply with the legal requirements, and shows HSE's procedures for handling safety cases and other submissions.
