This is because offshore profiles aren’t generally PC1, they are PC2 or PC2E and make use of a drop down below the deck edge in the event of an OEI fly away. The AW169 has a number of PC1 profiles suitable for ground based departures factoring obstacles above the take off surface, one of which utilises a very steep rearwards climb up to a maximum allowable TDP of 400ft above the surface which may be used appropriately for a site like a stadium, so long as the critical obstacles don’t exceed 265ft above the take off surface.
