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.

During August and September 2015, Sound & Sea Technology, Inc. (SST) successfully managed and participated in the assembly and systems integration of the first Wave Energy Conversion (WEC) device for the Navy’s Kaneohe Bay Wave Energy Test Site (WETS) in Hawaii. Since May 2015, SST has been assembling and integrating components for the Fred. Olsen Ltd. Lifesaver Energy Platform in preparation for eventual offshore deployment and testing at WETS.

The Lifesaver Energy Platform (LEP) is an advanced electro-mechanical point absorber WEC platform that uses unique point absorber hull and leading-edge power take-off (PTO) configurations. The Lifesaver Energy Platform will be tested and evaluated for approximately six months at WETS. The device was previously tested in waters off the United Kingdom and is one of the most advanced devices in the industry. The Lifesaver Energy Platform is the first WEC device to be deployed at one of the new WETS deep water test berths and is the result of the Navy’s interest in advancing renewable energy for Department of Defense applications.

As the Prime Contractor for WETS, SST has provided engineering support services to the Navy to upgrade and expand WETS since 2012. This includes technical input for operations and installation, mooring analyses and design, environmental and geotechnical site reviews, power cable testing and analysis, grid connection component design, power grid studies, preliminary and final WETS system design specifications, and execution of the WETS infrastructure installation process.

The figures below illustrate the LEP mobilization and assembly process. The system is designed to be easily transported and then fully assembled at or near an installation site. As of today, the Lifesaver Energy Platform is ready for installation at WETS after being assembled at Joint Base Pearl Harbor Hickam (JBPHH). The WEC is currently at temporary storage waterside at Marine Corps Base Hawaii (MCBH) Kaneohe awaiting final environmental documentation.

The Fred Olsen Lifesaver wave energy converter (WEC), which utilizes innovative technology to convert wave power into energy, received a special Hawaiian blessing Sept. 3 at Kilo Pier at Joint Base Pearl Harbor-Hickam (JBPHH).

Members of the Life-saver’s original design team, as well as contracting partners from Sea and Sound Technology, Inc., and representatives from Naval Facilities Engineering Command (NAVFAC) Pacific and NAVFAC Hawaii attended.

Rev. Kordell Kekoa of Kamehameha Schools performed a traditional Hawaiian blessing ceremony.

“This is a great opportunity for us at NAVFAC and the region to support renewable energy projects,” said Lt. Cmdr. Ivan Cavenall, energy program officer for Navy Region Hawaii.

“I think with different technologies that are emerging now, wave energy as a renewable source is important to consider. I think this [blessing] is a great way for us to show partnership and support for this type of venture,” he said.

The Lifesaver, considered one of the most sophisticated WECs in the market today, was developed in Norway by Fred Olsen Renewables and recently shipped to Oahu where it will be deployed for off-shore testing at the Navy’s wave energy test site (WETS), located at Marine Corps Base Hawaii (MCBH) in Kaneohe, set to start in October.

“The [Lifesaver] is probably the most developed wave energy device in the world right now,” said Matthew Ramey, an engineer with Sound and Sea Technologies, a contracting partner with NAVFAC Pacific and NAVFAC Hawaii in charge of overseeing and maintaining the WEC’s operation at MCBH.

“This is one of the only energy converters that have been in the water for any amount of time and has had serious testing done which makes it definitely one of a kind,” Ramey said.

According to Alexandra Devisser, NAVFAC Engineering and Expeditionary Warfare Center based in California, the Lifesaver was successfully deployed for two years at the Falmouth Bay Test Site (FaB Test), an English site where marine renewable energy devices are also being tested.

“The Fred Olsen company made some design improvements which are in the buoy’s current configuration and will be tested at the (WETS),” she explained.

“There will be other buoys going into the water in the next couple of years, so this isn’t the last of the different systems and configurations that we will see,” Devisser said.

Bryan Law, regional energy program manager for NAVFAC Hawaii, agreed that the Lifesaver is an innovative device that shows considerable promise for Navy applications of wave energy.

“Most installations in the Pacific [Rim] have pretty good access to waves and a shoreline, so there is good potential for those particular bases to reduce their fossil fuel use by being able to plug directly into the grid, so to speak, and harness this kind of wave energy,” he said.

“So we are definitely tracking and supporting thee [Lifesaver’s] progress, especially on the Navy side.”

The Eastern part of Washington State has recently been devastated by a series of wildfires that drew nationwide attention and continue to burn. During the peak of the infernos, SST team member Steve Mclaughlin received a call from state assemblyman Matt Shea of Spokane Valley. Matt inquired how long it would take Steve to mobilize support and supplies to 200+ families who had lost homes in the blaze. Always one to rise to the call of duty, Steve reached out to a wide and well established network of contacts to personally organize a mass relief effort.

 


Within a week Steve and his crew assembled two loads of relief materials consisting of sleeping bags, cots, tents, pet food, personal/hygiene items, cookware, and many other basic necessities.

The first two loads alone totaled over EIGHT tons.

Steve and his crew also organized the shipment and distribution of ten tons of hay and alfalfa for the displaced farm animals on the eastern part of the state.

Steve and his team delivered supplies directly to affected families consciously not asking them to come to a distribution facility. In addition to supplies, Steve and his crew provided building reconstruction aid and land support to the victims all at NO COST except for fuel donations. With all of this rewarding effort, a total of about 30 tons of supplies were gathered for the families and delivered in short order by Steve Mclaughlin and his crew. We are so proud of Steve and his team!

Aquaculture operations in net pens began and have continued in relatively sheltered waters for obvious reasons. However, as aquaculture has become more intense, space and environmental issues are creating limitations to growth of netpen aquaculture due to questions of sustainability and high concentrations of biomass in restricted areas of water. These limitations have created the impetus for aquaculture operations to adapt to deeper, offshore waters. Consequently, the resulting ripple effects of less-protected, deeper waters require more robust pens and mooring systems, and changes to operating practices.

One element of the implications of aquaculture operations moving into deeper water farther offshore is more expensive cost of providing power for feeding and monitoring of fish pens. Current systems generally are diesel powered, which requires refueling and maintenance by personnel transiting to the operation, which will increase as operations move further offshore. In addition, the aquaculture operations (feeding, removal of dead fish and monitoring of the fish pens) also will require longer and therefore more costly transits for personnel.

To maximize efficiency and minimize costs, offshore aquaculture operations will require autonomous, locally powered operations and monitoring. Autonomous means that the system is self-powered (not cabled to shore), and is unattended for routine operations. Unattended means that the system can perform for extended periods without maintenance, repair or resupply of consumables. Currently-available monitoring equipment, such as above- and below-water cameras (visual, IR, or thermal), acoustic, water chemistry and other sensors can provide continuous detection, assessment and alerts for surface and subsurface monitoring. Autonomous communications systems can use RF transmissions (e.g., extended WiFi such as SeaFi) to transmit data and report event alerts. Sensors and communications systems that can be adapted to these applications are commercially available.

The availability of reliable, long-life wave energy conversion technology, low-power sensors, and low-power local computer processing combine to make autonomous, self-powered, longlife operating and monitoring systems that can be installed and operated as part of an offshore aquaculture operation. The technology is available to develop and demonstrate such an operating system.

This system will have the following four key system features:

• Self-powered, using a demonstrated reliable, high-operational availability wave energy technology, with on-board energy storage, suitable for use in all water depths of interest
• Hybrid configuration, with combined wave energy, storage, and diesel backup • Autonomous, unattended operation with very high mean time between failures and high operational availability (goal mean time between failure of 1 year; goal operational availability(i.e. producing power) of 90 percent)
• Processing of sensor data with defined event alert thresholds (equipment malfunction, breach of nets, others).
