Abstract
A modular underwater well drilling platform includes a first guide base which is intended for connection to a subsea wellhead of an exploratory well and which includes a number of support frames radiating therefrom in various directions, these frames allowing for connection of further guide bases to the first base, each base including an opening through which a drill string can be passed. The size and form of the platform can be readily adjusted in the light of results obtained as drilling of wells progresses.
