Through Sealaska’s Woocheen group, Causeway Geotech is working together with other partner companies, including Seas GeosciencesCS Marine Constructors and Gregg Drilling , to address our planet’s climate crisis.


The name Woocheen is derived from the Tlingit word wooch.éen, which can be roughly translated as working together with the resources and environment around us.

Our Hydro Sciences teams bring together expertise in geosciences, construction, data science and more to keep freshwater clean, heal our oceans and support harnessing offshore wind energy.

Production of clean energy from our oceans is set for explosive growth, rising from supplying a negligible amount of energy today to potentially powering all of some countries’ energy needs within 20 years. We are helping harness the force of our oceans by supporting the rapid global expansion of offshore wind farm development. Our oceans can power the world.

Employing a global reach and a team of more than 1,200 engineers, scientists and other professionals, we are quickly becoming a leader in our industries.
