After several months of assembly, testing and integration, Sound & Sea Technology, Inc. (SST) successfully installed the Lifesaver Energy Platform (LEP) at the Navy’s Kaneohe Bay Wave Energy Test Site (WETS) in Hawaii, offshore infrastructure that was established and is managed by the Naval Facilities Engineering Command, Expeditionary Warfare Center. The Lifesaver Energy Platform is the first Wave Energy Conversion (WEC) device to be deployed at one of the new WETS deep water test berths and supports the Navy’s interest in advancing renewable energy for Department of Defense applications.

The Lifesaver Energy Platform will be tested in ocean conditions and evaluated for reliability and power output performance relative to wave height over approximately six months. The Platform is an advanced electro-mechanical point absorber WEC platform that uses unique hull and leading-edge power take-off (PTO) configurations. Sound & Sea Technology, Inc. is the Prime Contractor for WETS and has provided engineering support services to the Navy to upgrade and expand WETS since 2012.

Sound & Sea Technology, Inc. (www.soundandsea.com) is a woman-owned small business headquartered in Lynnwood, Washington, with a division located in Ventura, California and operations in Cork, Ireland. SST specializes in ocean engineering for complex undersea systems, for port and harbor security and renewable marine energy systems. The company provides ocean engineering, systems engineering, and program management support worldwide to the U.S. Navy other government agencies and firms that develop, build, and install systems and equipment in the ocean.

Sound & Sea Technology Inc. (SST) has recently completed the recovery, upgrade and redeployment of an undersea acoustic array which is part of a system the used by the U.D. Navy for subsea acoustic measurements (Figure 1). The array is moored near The South Tongue of the Ocean Acoustic Facility (STAFAC) on Andros Island, Bahamas (Figure 2) and has a tracking and communication system and seafloor cable system for power and telemetry.

The system consists of two vertical high gain measurement system (HGMS) array structures moored in 4,000 feet of water; an underwater tracking and communication system; and a seafloor cable system (with shallow water junction box) for power and telemetry from the United States Navy’s Atlantic Undersea Test and Evaluation Center (AUTEC) shore facility on Andros Island to the underwater array.

SST, with a Navy team, designed and installed the STAFAC mooring and mechanical systems, including a large A-frame (Figure 3) and has conducted all of the operations for maintenance and upgrades since 2008. For this recent upgrade task, SST prepared all the planning and engineering required for the recovery and installation of the array as well as at-sea operations including the vessel (Figure 4), diver and ROV support. SST personnel directed the at-sea operations for the installation of the North HGMS array, the upgrade of the STAFAC junction box, and the upgrade of the South HGMS array toward a successful outcome.

The work is part of an ongoing multiple award contract with the Navy to provide ocean engineering support to the Naval Facilities Engineering Command, Engineering and Expeditionary Warfare Center.
