My best friend is a planning/scheduling engineer for a Japanese company currently on a project in Indonesia (for over 2 years with 1+ more years to go). He and his Indonesian wife were PR's in Singapore as he's been working in the region for over 20 years (Singapore, Malaysia, Indonesia a number of times in each country). He recently lost his PR due to his current contract in Indonesia (not in Singapore the last two years of his REP at the time. He owns a
condo here, but he's renting it out and paying offshore tax rates on it.
What I'm trying to say is as you are a Project Controls Manager, you are also going to follow the O&G construction industries as well. The ICA knows this is the case for all in the O&G EPC industry. Therefore, the odds are definitely not in your favour as they know you will be going on to other areas when this project is completed. (your job history already proves this to them). Therefore, there is nothing to behoove them to give you PR as it appears that it will be a temporary affair till the next contract comes along. This is not what they are looking for in a "Permanent Resident". Therefore it's doubtful that you will be successful.
However, don't let that be a reason to stop you from re-applying. The worst they can do is tell you you are welcome to stay on your current EP. As long as you have thick skin, and multiple rejections don't bother you, you should be okay. Who knows, you just might win the lottery. Odds are stacked against you, but somebody eventually wins the lottery, don't they.
I spent 20 years in Oil Field Construction myself but retired from that about 20 years ago when I was about your age (a couple of years older). I left just because of the time away from home, so changed jobs, took a permanent position in Singapore and eventually got PR. (been here over 30 years now). Good Luck.
