Special 25
One of you "problems" may be a lack of confidence due to a lack of practice. Some oil companies insist that any crew that flies for them at night has to be night current which is a very good idea.
I am "lucky" I suppose in that I do about 600 night landings, to a variety of manned and unmanned platforms, each winter and therefore feel very comfortable at night. In fact I would rather shuttle at night than at the absolute day VFR min. My background also includes a lot of low level night flying in appalling weather which helps.
You talk about sparsely lit platforms but have you done anything about them? The smaller rigs in the SNS were improved with leg floodlights after pressure from the pilots.
The problems with inexperienced copilots can cause the odd "moment" but a good stabilised approach which you can monitor usually ends with a good landing.
I have noticed the increase in night departures so perhaps as more of us do night landings it will become more routine.
