Offshore Wind

Tetra Tech provides industry-leading, science-based permitting, siting, and environmental services and compliance-focused solutions for construction, operations, and maintenance to support the entire life cycle of the offshore wind supply chain.
Our team of planners, project managers, scientists, engineers, and regulatory specialists has supported the development and permitting of offshore wind projects ranging from 12 to 2,640 megawatts. Tetra Tech leverages our multidisciplinary expertise in marine-based and onshore generation and transmission services to successfully navigate the offshore wind regulatory process.
Tetra Tech supports offshore wind developers with initial project planning, including due diligence, fatal flaw analysis, and stakeholder engagement. We lead all local, state, and federal permitting and licensing efforts and provide construction and operations support, including comprehensive compliance services driven by data collection, evaluation, and management. Our protected species observers and client representatives are offshore supporting pre-construction characterization surveys and permit compliance, a critical component of advancing offshore wind in the U.S. and an opportunity to bring innovative software-based solutions.
Our onshore permitting and siting services include field surveys, evaluation of points of interconnection, routing, and alternatives assessments. Tetra Tech’s submarine cable services experts focus on cable route constraints analysis and engineering, marine survey planning, and in-depth studies.

Permitting and Licensing
Tetra Tech is at the leading edge of permitting for offshore wind projects in the United States, with engagement on dozens of projects on the east and west coasts. We have authored more construction and operations plans, site assessment plans, and survey plans than any other firm, including in-house development and management of dozens of surveys and assessments of resources such as acoustics, navigation and marine use, air emissions, biological resources, cultural resources, visual resources, and commercial and recreational fishing. Tetra Tech is proud to be leading permitting compliance for the largest offshore wind project under construction in the U.S., the Coastal Virginia Offshore Wind Commercial Project.

Data Management and Constraints Mapping
Data management is a critical component of successful offshore wind projects—from preliminary project planning through construction and operations. Building on established management systems, Tetra Tech hosts user-friendly data portals that enable real-time viewing of site-specific data to help identify constraints and provide a visual representation of the current project. The data can also be leveraged for compliance monitoring.
