A method is described of positioning an offshore platform jacket comprising the steps of: loading and securing the platform jacket onto a tension leg barge; towing the tension leg barge to a predetermined offshore location; laying anchors on the floor of the ocean at the predetermined offshore location; attaching lines between the anchors and the tension leg barge to position and maintain the barge above the predetermined offshore location; partially submerging the tension leg barge by shortening the lines between the anchors and the tension leg barge; completing the submerging of the tension leg barge by flooding the barge with seawater; and releasing the platform jacket from the tension leg barge and towing the jacket off the barge while the barge is submerged.
