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.

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.
