Navatek

 

Navatek is a world leader in designing and analyzing ship hull forms, ocean structures, underwater lifting bodies, and coupled hydrodynamic systems using its expertise in computational fluid dynamics (CFD) and complex engineered systems.

Navatek Ltd. was founded in 1979 and operates out of offices in Honolulu, Hawaii and Kingstown (Rhode Island) with over 65 employees. Navatek is a subsidiary of privately-owned Pacific Marine, founded in 1944 with 350 employees and annual revenues of $85 million. Parent company Pacific Marine also owns Pacific Shipyards International LLC, Hawaii’s largest commercial ship repair company. Navatek holds 28 U.S. and foreign patents on its inventions, with six more pending.

The research team has world-class expertise in advanced hull form hydrodynamic research and naval architecture. Navatek maintains its own shipyard facilities and demonstration vessels, supported by a staff whose breadth of experience spans all aspects of ship and boat construction, and vessel operations. Through hydrodynamics, naval architecture and ocean engineering expertise, Navatek is also developing innovations in wave energy conversion; utility-scale energy storage; wind turbine technology; and ballast water treatment systems.

Navatek supports the mission of APTEP through the programs funded by the Office of Naval Research (ONR). These include: development of advance computational tools for ship hull form optimization and integration with other computer aided design programs; the development of alternative energy systems which supports the Pacific Rim taking advantage of its rich alternative energy sources; and the promotion of STEM education to assist in developing an educated and technologically capable workforce.

  • Developing Advanced Tools & Models

    Developing advanced hydrodynamic analysis tools and predictive models to expand the design envelope, while simultaneously reducing the cost and time needed to bring concepts to commercialization

  • Moving Beyond Prediction to Experimental Validation

    Building small-scale and large-scale technology demonstrators/prototypes, instrumenting them, and testing them at sea

  • Multiple Applications

    Developing multiple applications for each technology (product line extension)

Navatek resources and tools:

Applied Engineering Division

Navatek’s Applied Engineering Division, founded in 1992, is responsible for constructing, modifying, outfitting and demonstrating at sea Navatek’s proprietary, patented small boat designs. The Division shares the Pier 41 shipyard owned by the sister company Pacific Shipyards International.

Computational Fluid Dynamics

Navatek employs a full complement of tools from simple empirical models, through proprietary medium-fidelity potential flow codes, to commercial Reynolds Average Navier Stokes (RANS) codes to perform these analyses. Navatek’s philosophy in CFD is “The right tool for the job”. Unique to Navatek is a history of full-scale sea trials that have proven the utility and validity of its CFD tool.

High Performance Computing

In June, 2003, Navatek acquired a 128 processor Linux cluster for use in its research and development on ship hull designs and underwater lifting bodies. This cluster, nicknamed Neptune, is used primarily for running Computational Fluid Dynamics (CFD) software applications. In 2007 Navatek added a second Linux cluster nicknamed Poseidon. Poseidon and its 36 processors has more than doubled the computing power at Navatek’s research and development office. In 2009, Neptune was replaced by multiple computer clusters.

Facilities / Shipyard

Navatek Ltd’s. parent company Pacific Marine is the owner of Pacific Shipyards International (PSI), the largest private shipyard in Hawaii. Navatek Ship Construction leases space at the PSI shipyard to build, modify, repair and maintain Navatek-designed advanced technology demonstrators. PSI has a combined workforce of 200 experienced production employees skilled in steel and aluminum fabrication, welding, pipefitting, mechanical, machining, and preservation and coating services.

Projects

Plasma Flow Control for Wind Turbines

Many of the challenges associated with reducing the Cost of Energy (CoE) generated by wind farms can be addressed by implementing active control of the blade aerodynamics.
Plasma actuators hold significant promise for a robust, efficient, and effective means of blade control, and when implemented, result in improved aerodynamic performance and reduced aeroelastic vibration.

Tools for the Navy Standard Design Environment

Improving the energy efficiency of the fleet continues to be a critical economic and operational goal for the U.S. Navy. Reduced ship energy consumption reduces life-cycle costs, improves endurance, and improves war-fighting effectiveness.
Navatek, Ltd. is executing a four-tiered approach to integrating physics-based computational tools into the Navy standard design environment.

Navatek’s mission is to develop technologies which improve the sea-keeping, sea-kindliness, speed, and fuel/transport efficiency of both large ships and small craft
