Caldwell Marine International

What Caldwell Marine International does

Caldwell Marine International (CMI) is a heavy marine construction contractor headquartered in Wall Township, New Jersey, specializing in submarine cable installation, nearshore wind cable installation, and heavy civil marine construction. Founded in 1960 and operating for over 65 years, CMI serves investor-owned utilities, public power authorities, offshore wind developers, telecommunications carriers, and municipal clients across the U.S. and Canada. Named customers include the New York Power Authority, National Grid, ConEdison, PSE&G, Eversource, Orsted/Deepwater Wind, NKT, Prysmian, and Mitsubishi International, with marquee projects including the Block Island Wind Farm (first U.S. nearshore wind farm), the $295M Vancouver Island Transmission Reinforcement, the $68.7M Lake Champlain cable crossing, and multi-phase work on the Champlain Hudson Power Express. The company is a Hispanic-owned MBE-certified subsidiary of JAG Companies Inc., alongside sister firms Northeast Remsco Construction and Huxted Trenchless.

CMI's core technology centers on a specialized marine equipment fleet: a Dynamic Positioning (DP-II) cable lay barge, jet sleds capable of burial to 5.0m+ depth, linear cable engines, ROV touchdown monitoring, and — uniquely among U.S. cable installers — a subsea-tracked trenching vehicle (Hi-Traq Jetter) purpose-built by Royal IHC. Horizontal directional drilling (HDD) is delivered in concert with sister company Huxted Trenchless for nearshore wind and shore-approach work. The company maintains an Atlantic waterfront yard supporting equipment mobilization and modular equipment design enabling deployment to remote sites worldwide.

CMI generates revenue through project-based contracts awarded via competitive bidding and direct engagement with utilities, power authorities, cable manufacturers (NKT, Prysmian, LS Cable, ABB), and government agencies. Projects are large, multi-year infrastructure deployments with values ranging from tens to hundreds of millions of dollars. The go-to-market motion is enterprise field sales targeting large infrastructure projects, supported by participation in offshore wind industry events (US Offshore Wind 2023, IPF 2023), the company website, and a careers page that doubles as employer brand marketing. No public pricing, recurring revenue, or financial disclosures are available.
