Notwithstanding points CAT.OP.MPA.192, NCC.OP.152 and SPO.OP.151, the pilot-in command/commander does not need to specify a destination alternate aerodrome in the operational flight plan when conducting flights from an offshore location to a land destination aerodrome provided that sufficient operational contingency is in place to ensure a safe return from offshore.
SPA.HOFO.125 Offshore standard approach procedures (OSAPs)
(a) An operator shall establish procedures to ensure that offshore standard approach procedures (OSAPs) are followed only if: (1) the helicopter is capable of providing navigation and real-time obstacle environment information for obstacle clearance; and (2) either: (i) the minimum descent height (MDH) is determined from a radio altimeter or a device that provides equivalent performance; or (ii) the minimum descent altitude (MDA) is applied and it includes an adequate margin.
When an OSAP is followed to a non-moving offshore location (i.e. fixed installation or moored vessel) and a reliable GNSS position for the location is available in the navigation system, the GNSS/area navigation system shall be used to enhance the safety of the OSAP.
