You can do all of that, including refuelling, within 45 seconds? Wow.
To the OP, the aircraft will have to land on and landing checks completed. Lifejackets would then have to be unloaded by the deck crew then put on by the passengers. These passengers would then have to be loaded and secured before take off. Conservatively, this whole process will take at least 5 minutes, maybe nearer to 10 minutes for a deck crew and passengers who aren't very well practised. (3-5 minutes is an average turnaround time for a smaller, very experienced and practised NUI crew).
Once that helicopter has cleared the deck, the next helicopter can be given 'deck available' by the HLO. So, depending how far out on the approach the next aircraft is, anywhere from 30 seconds to several minutes between t/o and landing. A sensible estimate would be 1 - 2 minutes.
