About the Company

Turnkey Project Delivery

For nearly 30  years, Longitude 123 has been providing marine project consulting and construction management to owners and operators of coastal and inland  energy-related facilities. These services include turnkey engineering and design, project planning, environmental permitting, performance and management of marine and underwater construction and decommissioning projects.

Our model provides the client significant advantages over traditional marine project planning by integrating the technical planning with the regulatory permitting process to produce permitted feasible means and methods at lower costs and on schedules tailored to our client’s requirements.

Structural, Mechanical & Civil Engineering

Through the acquisition of Ventura-based engineering firm Thomas and Beers, LLC,  Longitude 123 provides a team of licensed in-house engineers specializing in structural mechanics, mechanical engineering, design, and finite element analysis to complement our project management services.
