CapRock Awarded Cal Dive Contract

Leading satellite communications provider and subsea contractor sign multi-year deal

HOUSTON, TEXAS - July 24, 2007

Cal Dive International, a subsidiary of Helix Energy Solutions Group and a global leader of marine construction and diving services, signed a long-term agreement with CapRock Communications to receive broadband satellite communication services.

As the world’s largest operator of dive support vessels, Cal Dive knows what it takes to deliver the highest level of service to its customers. For critical operations such as subsea construction, deepwater maintenance and repair of offshore production and pipeline infrastructure, reliable communications is a must.“With CapRock’s communication solutions, we’re able to focus on what matters most to us,” said Cal Dive CEO Quinn Hebert. “Reliable communication services improve the efficiency of our daily operations while also providing the means for our employees to stay connected with their families and friends back home. That’s why we chose CapRock.”

Under the terms of the agreement, CapRock will provide the contracted vessels with Voice over IP (VoIP) services, broadband Internet access and high-speed connections to its corporate voice/data network.

This new agreement builds upon an existing arrangement where CapRock has been providing communications to several vessels in the fleet. “The expansion of CapRock’s relationship with Cal Dive demonstrates how customers are able to count on CapRock to deliver reliable communications with unparalleled service and support,” said CapRock CEO Peter Shaper. “We look forward to our extended relationship with Cal Dive as well as the opportunity to continue to provide them with enhanced services they have come to count on.”
