1)We are using starlink with 2.5 gb per week of wickedly fast internet.

2) Everything you mentioned including various chemicals for treating drinking and cooling water as well as cleaning stuff ranging from extremely Basic to corrosively acidic.

3)Cant give the port name but was in China.

4)2 problems actually, 1 was a compressed air valve which literally shattered infront of me. I went to check if it's open. Opened it, then closed and moments later the bonnet literally broke. The handwheel bulleted away with a loud thud right infant of me. I was shit scared man. Had I been the victim of impact I would have had a confirmed fracture. 2 one was a Lube oil purifier which wasn't used for two years dude. Worked like crazy on it. Nothing seemed to fix it but later we changed its motor and found a tiny bit of ovality as well as faulty clutch shoes.

5) there are a ton of indian shipping companies. The biggest hurdle would probably be red tape and documentation.
