Making ghusal without soap

Q:

1. If one takes ghusal without any soap and sampoo and just uses the water, will ghusal be valid ? I just went in rinsed the dirt off my body and made ghusal normally and came out.

2. If one has mistakenly had a pee drop in the underpants would ghusal be waajib?

3. How does one take ghusal at sea and would ghusal be accepted if there is others swimming in the ocean as well while one just went in to swim with a shorts. Would the ghusal be valid is one's owra is open?

Wearing undergarments in the state of ihraam

Q: The following two errors were made by me unintentionally whilst in Ihraam.

1) When I put on the Ihraam I forgot to remove my underpants. I realised this after about 20 minutes. I removed it immediately thereafter.

2) After coming out of the toilet, I washed my hands using soap unintentionally. Please advise what compensation is due from me, and please advise whether the compensation must be paid/done in Makkah or if it can be done here.
