As part of a Unified Command that consisted of the USCG, NJDEP, PSE&G, Con Edison, and LeFrak (the property owner), Caldwell Marine was contracted by Con Edison & PSE&G to locate and repair a dielectric fluid leak in Jersey City, NJ. The leak was on a 345KV power line that spans from Jersey City, NJ through NYC to Williamsburg Brooklyn, NY. The line was located 10’ below the water surface and 15’ below the mudline on the Jersey City side where the work took place. To locate the leak Caldwell used commercial divers to excavate the mud to first locate the power line and eventually to find the leak. Once located, the leak was stopped by use of a manufactured clamp provided by Con Edison. The clamp was placed on the existing line, filled with grout and the excavated material was backfilled to match the original river bottom.
