Hellenic Cables | Baltimore Sea Cables Manufacturing Facility

Hellenic Cables, a leading manufacturer of submarine and terrestrial power cables, chose Baltimore for its first U.S. manufacturing footprint — a 40.63-acre sea cables plant built to supply Maryland’s offshore wind program and the broader East Coast transmission build-out. Heffron is delivering the full mechanical scope for the new facility.

A plant of this kind doesn’t tolerate mechanical compromise. Continuous-process cable manufacturing depends on tightly controlled process cooling, compressed air, plant utilities, and HVAC running in concert across a very large footprint. Heffron is engineering and installing those systems from the ground up — coordinating with the design and construction team, self-performing the pipefitting and equipment work, and building in the redundancy a 24/7 production line requires.

This is the kind of project Heffron is built for: a long-horizon, mission-critical industrial facility where the mechanical backbone has to be right on day one and serviceable for decades. It also reflects what we want our work to mean — American manufacturing capacity for the energy infrastructure the country is going to need.
