This guidance is for anyone who has duties under the Offshore Installations (Safety Case) Regulations 2005 (SCR 2005), for example licensees, production installation operators, non-production installation owners and well operators. SCR 2005 covers oil and gas operations in internal waters (eg estuaries).
The Offshore Installations (Offshore Safety Directive) (Safety Case etc) Regulations 2015 (SCR 2015), which came into force on 19 July 2015, now apply to oil and gas operations in external waters, that is the territorial sea adjacent to Great Britain and any designated area within the United Kingdom continental shelf (UKCS). SCR 2015 replaces SCR 2005 in external waters, subject to certain transitional arrangements. These regulations are explained in the associated guidance document L154.
