In coordination with the SPAWAR Systems Center (SSC), San Diego, Makai Ocean Engineering, Inc. is proposing to develop an Autonomous Burial Vehicle (ABV) to install U.S. surveillance arrays. The proposed work focuses on: (a) designing an ABV that can bury a long surveillance array following a pre-determined route on the seabed (b) manufacturing a full-scale ABV prototype able to perform the mission, c) testing and evaluating the ABV performance with an array provided by the Navy, and d) delivering the prototype vehicle to the Navy for further testing at selected CONUS locations. This effort will culminate in an at-sea demonstration of the full mission sequence (from deployment to retirement) scheduled for August 2014.

In coordination with the SPAWAR Systems Center, San Diego, Makai Ocean Engineering, Inc. proposes to develop an autonomous Array Burial Vehicle (ABV) to install U.S. surveillance arrays. The proposed work focuses on: (a) developing an overall vehicle concept for an autonomous vehicle that will install and bury an underwater sensor array to protect it against fishing threats, (b) performing analytical and experimental analysis of critical elements of the installation and burial system to characterize the physical limits and trade-offs of the system proposed, and (c) providing convincing support of the feasibility of the proposed conceptual design, integration techniques, installation method and approximate cost. Makai"s innovative use of water jetting technology in the ABV substantially decreases the power requirements when compared to conventional plowing techniques. The jetting components, which are small in size and consume low amounts of power, will be incorporated into a light weight"torpedo shape"vehicle. The light weight ABV will help minimize the propulsion requirements, further decreasing component sizes and overall cost. The ABV will be more manageable and easily deployed from a variety of platforms, allowing the Navy to deploy arrays in softer soils and steeper slopes than those that can be achieved with conventional plows.

Various embodiments include a plate-fin type heat exchanger constructed from foil-fin layers of corrugated fins sandwiched between two sheets of thin metal plate or foil. The corrugated fins are laser welded to the metal sheets, creating continuous joints along the length of fin crests formed in the sheets by the corrugated fins. Foil-fin layers in a stack are separated by spacers or header bars to create adjacent flow paths to finned chambers with walls defined by outside faces of adjacent bonded plate-fin layers. The foil plates and the corrugated fins may be of similar or dissimilar metals. Embodiments include methods of manufacturing such heat exchangers including applying a vacuum to an assembly of corrugated fins sandwiched between sheets of thin metal plate or foil, causing fin crests in the sheets, mapping locations of the fin crests, and using the map to perform high speed laser welding along the fin crests.

An underwater cable burial mechanism including a nozzle disposed in front of a plow blade wherein the nozzle is configured to spray a jet of water onto the sea floor in an intended path of the plow blade to bury a cable in the sea floor. In an embodiment, the underwater cable burial mechanism may include two or more straight flow nozzles disposed in front of the plow blade at various angles and heights. In an embodiment, the underwater cable burial mechanism may be a component of an array burial vehicle, the array burial vehicle further including a pump to provide water to the nozzle(s), cable pack to hold a cable array, at least one ski configured to ride along the sea floor, and at least one thruster configured to propel the array burial vehicle along the sea floor.

A pipe attachment assembly for attaching a pipe to another structure so stresses are reduced within the assembly includes a sleeve positioned either within or outside the pipe which is composed of a material stronger than the pipe material, and an elastomeric bonding material which fills a gap between the pipe and the sleeve. The elastomeric bonding material transfers forces which are externally imposed on the pipe to the sleeve. This reduces bending, compression, tension, or torsion of the pipe in response to external forces, which in turn reduces the risk of a pipe failure at or near the termination or a breach where the pipe forms a joint with other pipes or containers. Various configurations may further improve the transfer of shearing stresses from the pipe to the sleeve, for example varying the width and/or the shear modulus of the elastomeric bonding material along the length of the pipe.

Makai proposes to complete a parametric analysis of candidate sonobuoy components for a conceptual deep drifting sonobuoy system. These results will enable the Navy to perform a tradeoff analysis of the sonobuoy system to meet their operational requirements and form-factor constraint. Using Navy-supplied location data, Makai will characterize the ocean environment in the area of operation and use Navy 4D temporal ocean current models as input to a hydro-mechanical numerical model to evaluate the dynamic loads on the different sonobuoy components (especially on the long and thin tether) will be compared to the manufacturer-specified component limits. The drift of single and multi-buoys over 30 days will be observed, as the acoustic coverage is an important metric for the Navy. The goal of this parametric study is to characterize how various component parameters (e.g., tether diameter, sizes, drag, weights, specific gravities): 1) affect individual sonobuoy space and weight; 2) perform against the system 30-day operational requirement and form-factor constraint; and, 3) influence single and multi-buoy geometry and barrier drift.
