Power generating ship

Dear All:
I am looking for a power generating ship, power up to 50MW - 100 MW.
This ship will be used in one construction work for a steel plant, where is quite close to the sea but far away from everything, no people, no powerbrid, nothing.
The construction could last for 3 - 5 years, and there is a power plant within this project. So, when project is finished, the power ship can run away.
Now the question is:
Is there a kind of leasing service for this power generating ship?
Please help me as a maritime new comer.
my mail box is:
Wish good news from you and thanks a lot !!
