    This paper presents a new low cost repair and strengthening method for steel offshore structures which offers potential savings in three areas: weight, installation and inspection requirements. It outlines the evolution and development of the new patented technique (the â??grouted stud/strap connection? from two existing and proven technologies, namely grouted pi/e-sleeve connections and stud friction welding.

    A testing programme covering static strength and fatigue behaviour of the connection is described which, on satisfactory completion, led to Certifying Authority approval of the new repair/strengthening method and the associated design procedure.

    The above mentioned benefits of the stud/strap technique are quantified in the paper by comparison with currently available grouted repair methods.
