Under the 1982 Act, CAA is responsible for operation of the Air Navigation Order (ANO). The legislation is supported by Civil Aviation Publications (CAPs). CAP 437 [Ref: 40] is the primary UK aviation standard for the design of offshore helidecks. This standard contains the criteria that an AOC Holder will use in order to authorise the helideck for use by Flight Crews.
Offshore helidecks fall within the definition of ‘unlicensed aerodromes’ and are outside the CAA licensing remit. However, the CAA will provide advice on any items of non-compliance with the helideck physical characteristics and emergency equipment requirements according to the guidance provided in CAP 437.
Acting on behalf of the offshore helicopter operators, BHAB Helidecks assess and inspect helideck designs and apply appropriate operational restrictions where there are non-compliances. The CAA monitors the operational restrictions that are imposed by BHAB Helidecks through its regulation of the helicopter operators. It is therefore important to realise that non-compliance with design criteria of CAP 437 may result in significant loss of helicopter operational flexibility (e.g. reduction in available payloads or even a landing ban in certain weather conditions).
Frequently found non-conformities during BHAB Helideck inspections are highlighted in the appropriate sections of these guidelines.
4.2.2 Offshore Helidecks Legislation & Enforcement
This section addresses the regulatory requirements and enforcement affecting Offshore Installation operators, mobile offshore drilling unit (MODU) owners and, where appropriate, vessel owners.
The responsibility for regulating and enforcing the health, safety and welfare of employees offshore rests with the HSE – Offshore Division (OSD).
4.2.2.1 Health and Safety at Work Act
The Health and Safety at Work, etc. Act 1974 (HASAWA) [Ref: 1] is the principal legislation safeguarding the health, safety and welfare of workers in the UK offshore oil and gas industry.
The Act applies to places and activities specified in the Health and Safety at Work etc. Act 1974 (Application Outside Great Britain) Order 1995 (SI 1995/263) [Ref: 4]. This includes helideck activities on offshore installations, but not helicopters while in flight.
Flag State laws and ICAO and IMO conventions may also apply to shipping activities (e.g. specialist vessels).
MODUs may be both Installations and ships and, therefore, have to comply with both regimes.
The Offshore Installations and Wells (Design and Construction, etc.) Regulations 1996 (SI 1996/913) – (DCR) [Ref: 8] place responsibility for ensuring the safe design and construction of offshore installation landing areas on the installation duty holder. This generally means the operators of fixed installations and owners of mobile installations, floating production units and some vessels.
4.2.2.2 Offshore Legislation
The Offshore Installations (Safety Case) Regulations 1992 (Sl 1992/2885) – (SCR) [Ref: 5] require Operators and Owners to submit a Safety Case (See Appendix 2) which demonstrates that they have an adequate safety management system, have identified major accident hazards, assessed the risks from those hazards, and taken the measures necessary to reduce the risks to persons to as low as reasonably practicable (ALARP).
