Appendix 12 Helicopters as a secondary
Search & Rescue task
A12.1 Introduction
This guidance is intended to cover SAR as a secondary task to the offshore support contract and is appropriate to over water operations only. It is not intended to cover contracted public transport Helicopter Hoist Operations (HHO) e.g. marine pilot transfer, or to cover specialist primary SAR. The threshold between primary SAR and SAR as a secondary task is likely to occur when there is a requirement identified to conduct HHO from a life-raft at night, this normally being considered as a primary SAR task. Additionally, consideration should be given to specialist primary SAR when hoisting out of sight of land, in poor weather or in high sea states.
Additional information relating to Search & Rescue can be found in Section 12 -Emergency response planning and Appendix 9 Winching (hoisting) operations of this guide.
A12.2 Management
Comprehensive guidance on the planning and co-ordination of SAR services is available in the International Aeronautical and Maritime Search and Rescue (IAMSAR) Manual (IMO/ICAO Doc 9731-AN/958). Volume 2 (mission co-ordination) of this manual is focused on planning and co-ordination of SAR operations and exercises.
Where secondary SAR is tasked, the scope of the SAR cover should be clearly defined and include radius of action and time on task, whether daytime only or night and day, and minimum weather, including sea state and maximum wind. The oil company should include a comprehensive SAR plan within its emergency response plans. There should also be a clearly defined interface between the emergency response organization of the oil company and that of the helicopter operator. The oil company will need to define:
. an SAR authorization process, including authorities to request call out; and
. an ‘authorization to launch’ process. SAR as a secondary task to the contract will normally have been generated following a structured risk assessment of passenger survivability within the context of national or regional SAR capabili-
ties. While individual oil companies would normally provide their own guidance on risk assess-ment, background guidance on survivability can be found in the Transport Canada TP13822E
– ‘Survival in Cold Waters’ (web site: http://www.tc.gc.ca/marinesafety/TP/Tp13822/menu.htm). The risk assessment should also include the survivor drop-off points (e.g. daytime use only or lit at nights) and the decision-making process for different types of injury.
Any helicopter operator contracted to provide secondary SAR will normally have experience in the provision of primary SAR services to national SAR agencies. Such operators would normally employ an SAR Standards Manager with past civil or military SAR experience.
A12.3 Operating standards
A12.3.1 Operations manual
Operators carrying out SAR as a secondary task should hold an approved Operations Manual which includes supplements containing material specific to helicopter hoist operations and SAR tasking. In particular the supplements should address:
.
Details about the system to de-conflict airspace and communicate with other SAR assets.
.
Crew qualifications (to include offshore experience and Instrument Rating).
.
Crew training (to include proficiency and line-check requirements).
.
Duties and responsibilities.
.
Pre-flight preparation and briefing.
.
Minimum HHO equipment.
.
AEO and OEI performance criteria.
.
If required, the conditions under which offshore HHO transfer may be conducted including the relevant limitations on vessel movement and wind speed.
