Makai Ocean Engineering was founded in 1973 as a diversified ocean engineering company. Practice areas include engineering for ocean based renewable energy, large underwater pipelines, software for planning, simulation, installation and recovery of submarine cables and arrays, and software for visualizing scientific 4D/5D data.

Makai supports APTEP’s mission on the Science and Technology side of the triangle. Makai employs a number of master’s and PhD level engineers who are developing unique, proprietary technology related to marine renewable energy, energy efficiency, and ocean engineering.

Makai’s technology directly enhances its private sector work in these areas, supporting the Commerce side of the triangle. Specifically, technology such as heat exchangers, marine pipelines, ocean thermal energy conversion (OTEC), and seawater air conditioning (SWAC) system designs, are being exported to international markets, with recent customers residing in China, Japan, Korea, Australia, Pacific Islands, Africa, France, and Latin America.

Makai also contributes to improving education and awareness of these unique technologies with its presence in the community and by collaborating with APTEP educational partners.
