You definitely need to look at aircraft individually but in broad brush terms, an onshore approach to a helipad (elevated or otherwise) is made direct to the landing point. The angle of approach varies a bit, and sometimes you got pure vertical or sideways but the general intention is to go straight to a point in the low hover above the pad.
Offshore you could also use this Cat A approach but this would probably limit you in max mass terms. In that case you might aim off then slide in much like some ship approaches.
