with drilling risers in high currents. The helical grooves actually channel water around the riser and convert it into a rotational flow, which ‘pins’ the riser in place to lower drag forces. The product is a result of a joint development exercise between Trelleborg Offshore and Diamond Offshore Drilling, and it has been thoroughly qualified in simulations and hydrodynamic testing, as well as through successful deployment on a number of drilling rigs in the Gulf of Mexico. With the combination of VIV mitigation and low drag, performance has been shown to rival fairings, yet this integral

"... Contracting seventh-gen rigs at $400,000 per day suggests some desperation on the part of management to secure tenor at the expense of rate," Barclays analysts wrote in a note.

in the deep water in the foreseeable future," he said. "Most of the prospects that we are developing right now are literally in jack-up rig territory, which is 300 feet or less." Jack-up rigs - mobile platforms with a floating hull - were the one bright spot in rig contractor Diamond Offshore Drilling Inc's recent quarterly results. Revenue from its deepwater business declined. Shallow-water wells are also cheaper. Using infrastructure left over from earlier drilling, they can be installed for about $10 million; a deepwater well would cost upward of $50 million. The returns, so
