Diamond Offshore signs joint development agreement with Trelleborg to manufacture and market new helical riser buoyancy design
Diamond Offshore Drilling, Inc. and Trelleborg's offshore operation announced a Joint Development Agreement to develop, manufacture and market Helical Buoyancy™ riser technology developed by Diamond Offshore. This innovative, patented riser buoyancy design reduces riser drag and mitigates Vortex-Induced Vibration in offshore applications and enables improved operational efficiency.

This solution is an alternative to adding fairings or strakes to the drilling riser and can reduce deployment time and operating expense. The Helical Buoyancy design also improves safety in challenging environments by eliminating the need for personnel to work below the drill floor to attach a separate apparatus.

The "helical" design is the result of several years of development by Diamond Offshore utilizing Computational Fluid Dynamics and high Reynolds Number Wind Tunnel testing. Diamond Offshore will work with Trelleborg on further application engineering, data acquisition, testing and development of Helical Buoyancy applications across the offshore drilling market.

"Development of this new technology for riser buoyancy is even more important as drilling moves into deeper waters," said Ron Woll, Senior Vice President and Chief Commercial Officer of Diamond Offshore. "We continually look for ways to improve the economics of offshore drilling for our customers, and this new buoyancy design will enhance drilling efficiencies in high-current environments."
"At Trelleborg, our goal is to perform at every level to deliver innovative and reliable offshore solutions and we welcome this opportunity to team up with Diamond Offshore on this exciting venture," says Alan McBride, Vice President at Trelleborg's offshore operation in Houston.

In conjunction with this agreement, Diamond Offshore has ordered Helical Buoyancy from Trelleborg for drilling risers on the Ocean BlackRhino and Ocean BlackLion, two of Diamond Offshore's sixth-generation drillships currently under contract in a high-current area in the Gulf of Mexico.

"This technology advancement is the result of Diamond Offshore's engineering expertise and thought leadership and should benefit the broad offshore drilling industry as it gets adopted," said Woll.
