Established in 2019, CLT is a leading service provider in the Northeast's rapidly growing offshore wind sector. Born as a strategic spin-off from Boston Line & Service, we carry forward a legacy of unmatched marine service that has graced the Port of Boston since 1933.

​

Our heritage is more than just a timeline—it's a testament to our unparalleled expertise. At CLT, we seamlessly blend decades of marine experience with a commitment to fostering sustainable local opportunities. For our clients, this translates to superior service, informed by years of industry know-how.

A shining example of our dedication and proficiency is our collaboration with Prysmian on the groundbreaking Vineyard Wind project.

Recognized as the US's first industrial-scale offshore wind endeavor, the Vineyard Wind project stands as a monumental step for the country's offshore wind sector. CLT proudly holds the distinction of executing the project's very first crew transfer in November 2022. Since then, our team has completed over 1000 transfers for Prysmian during their export cable laying phase, underscoring our unmatched capabilities in the offshore wind arena.

With hands-on experience, we've gained a profound understanding of the operational intricacies and unique challenges posed by offshore wind projects. Choose CLT—where tradition meets innovation, and expertise guarantees excellence.
