Oil companies need to start spending on green light strobes on the deck after you've been given landing clearance. No green strobe, no landing.
Two colour helideck lights, default condition is bright red. When the HLO is happy that is deck is ready, and the crew call for availability, only then does he turn them green.
Crew can see the change from red to green and get a visual confirmation they are at the right deck.
Can't be that difficult.
