You obviously haven’t read my CV, or understood much of my many posts here.
Aside from owning a boat and spending my time with other Expats in the Marina and at the Singapore Town Club, you are all wrong.
BTW; I did own a car until 1994, but found out that I didn’t need one to get around in Singapore. For private trips in Malaysia I rented a car in JB.
As to my immigration status it varied during all those year. The first 6 years (1967/73) I was either signed on a ship, or did the “Causeway run”.
I started a company in Singapore in 1973, but with the Shipping Crisis in 1974 I switch to Freelance jobs. Yes I did frequently go offshore, but as a Warranty Surveyor, Rig mover, Towmaster.
I also worked “onshore”, as Loadmaster, Marine Consultant, Marine Advisor, Marine Superintendent, Marine Manager and a host of other “titles”. (The "grandest was probably “Marine Advisor to the Board of Directors” in an Offshore Construction Company in Singapore)
From 1973 I had an Employment Pass, until I applied for PR status in 1991, which I retained until I moved out of Singapore in 2016. (Having to que up with the tourists at the Immigration Counter on arrival back was a “cultural shock”)
As for “working Offshore”;
I only worked a scheduled Offshore job (28/28) as Captain on a Drillship in 1978-80. Otherwise I worked worldwide; from the tip of South America (Tierra del Fuego) in the South West to the North of Norway in the North, Sakhalin in the North East. and Australia in the East. But with Singapore as a base and home.
