ABSTRACT:
Conductors for use with a guyed tower offshore platform and a method for installing the conductors on the guyed tower. A conductor sleeve, e.g. a length of heavy-walled casing, is secured in a retracted position within at least the lowermost conductor guide of each set of vertical aligned conductor guides on the guyed tower. The guide sleeves are lowered with the guyed tower as the guyed tower is installed on location in a body of water. The sleeves are then released and are driven or otherwise penetrated into marine bottom to a depth equal to or preferably below the center of rotation of the guide tower. A conductor is then passed downward through its respective guides and guide sleeve and is driven to refusal in the marine bottom. By providing a heavy-wall sleeve which spans the interval between the lowermost guide and the center of rotation, any deflection in the conductor caused by the rotation of the guyed tower is spread over a greater length than that which would normally occur in a conventionally installed conductor, thereby insuring the conductor of the present invention will stay within acceptable curvature and stress limits required in normal drilling and/or production operations.
