Vendor information, data sheets, operating instructions and maintenance and test manuals should also be obtained for each piece of procured equipment and provided for use on the facility.
4.4.7 Limited Helideck Operations
In the event that helideck operations are likely to be restricted as a result of design or construction deficiencies, the problems likely to be encountered and the likely costs incurred by the duty holder during operations should be clearly understood and justified to the helideck owner by the designers.
Installation operators, MODU and vessel owners should instruct Topsides and Helideck Design Contractors to advise them formally of any helideck or associated system deficiencies arising from the overall installation, MODU or vessel helideck designs that may give rise to helicopter or helideck operational restrictions and / or additional operating expense.
5.0 DESIGN SAFETY CASES
5.1 INTRODUCTION
The Offshore Installations (Safety Case) Regulations 1992 (SCR) (SI 1992/2885), among other things require installation owners and duty holders to identify all hazards which could cause a major accident, including helicopter accidents, and to take measures to reduce the risks to as low as is reasonably practicable (Regulation 8).
The approach taken when making these Regulations was to set objectives. The objectives were then expanded further in guidance on the regulations.
However, it is noted that, with respect to helicopter operations, the guidance on Safety Case Regulations is focused mainly on the hazards and risks to an installation and its personnel from impacts by aircraft. It does not specifically encompass the hazards and risks to a helicopter and its passengers from the installation and its processes.
Duty Holders, including Designers, should adequately address the potential effects on helicopter flight operations caused by adverse operating environments created on and around offshore installations. These adverse effects may result from production and power generation processes and structures on the installation or from adjacent installations and vessels. When combined with local weather conditions the resultant effects can place helicopters in jeopardy, particularly during critical flight phases. Duty Holders including Designers should, in particular, assess any hazards due to hydrocarbon gas release, exhaust emissions, physical turbulence generation and lit flares. Failure modes of installation, MODU or vessel systems that have the potential to affect the safety of helicopters should also be assessed (e.g. loss of heading control on a vessel whilst a helicopter is located on the helideck). References to these studies should be made in the Design and Operations Safety Cases.
HSE has recognised the need to consider the hazards to helicopters created by an installation, MODU or vessel. The joint HSE / CAA research project resulting in CAA Paper 99004 [Ref: 41] concluded (Conclusion No: 29) that guidance in the past has been solely and erroneously concentrated on the risk to the installation and has not explicitly encompassed the hazards the installation may pose to the helicopter. HSE Safety Notice 4/99 [Ref: 23] draws duty holders’ attention to the need to consider installation or vessel induced hazards for helicopters.
