Thanks,
so as has been discussed, the problem is the VMC handling at night, having to make a decision close to a platform, when the weather is marginal is not the easiest decision to make. So take away the issue.
At night all approaches to offshore installations made using an ARA profile. Takes the decision making out of it. Added with the previous post i made about night ARA's to 500' 1 nm and a set ground speed this should giv you the sight picture that the PNF would need to see when they become visual and a constant approach every time. coupled with a day VMC approach with the same gate of 1 nm 500' and G/S fixed then you would get the same sight picture day or night.
