Interestingly the US Navy will not carry "passengers" to and from ships outside daylight hours or after 60 minutes before sunset.
Maybe they know something?
I think the question needs to be asked as to "why" you have to fly at night.
Regular crew changes? Those things are changing as well as the rosters change with the current oil price and folk are being let go.

As to NVG's I think you may find that is not really the way forward and there are limits as to how far you can take it.
Issues being that as you are pretty much relying solely on the device it needs to meet a whole truckload of standards which they will struggle with.
Plus it is a portable device which brings another can of worms. No doubt it works but how do you "certify" it and what are the rules going to be.
It ain't VFR, Night VFR or IFR as you know it. We are talking about Transport Category aircraft and regular pax ops here not the military.
Enhanced and/or Synthetic vision which is part of the aircraft seems to be the way forward and systems are already certified in the plank world
with lower minima approved.
For the whole time to date of offshore night operations possibly hasn't changed in 30 years. A poxy little ring of lights out the window somewhere?
We know it has knobs on it. Thats why we are speaking about it here and it has been proven to be.
