Balmoral Offshore Engineering introduced two additions to its drill riser buoyancy portfolio at the OTC. The new materials, Durafloat Superlite and Durafloat Superlite-X, are rated to operating depths of 15000ft; typically 3000-5000ft deeper than industry-standard drill riser buoyancy. The syntactic foams are an extension to the company’s existing Durafloat range and were developed by the technical and engineering teams in Aberdeen as part of a six-figure R&D investment program.
