Cover: Dredge Peter de Jong to Join Marinex Fleet
The Marinex clamshell dredge Peter de Jong, nearing completion at Detyens Shipyard in Charleston, South Carolina. Marinex owner Hammond Johnson surprised de Jong last Fall with the news that the dredge would be named after him. De Jong engineered the complete conversion of the Navy crane, and with the help of Marinex employees gutted it and installed all-new machinery, giving it a lifting capacity of 200,000 pounds. Kevin Williams furnished the electrical installation. Marinex did all the machine work in its own shop, and structural changes were done at Detyens Shipyards. The hull is 140 feet x 70 feet x 12.5 feet. In January, Ray Bergeron delivered a 50 cubicyard Cable Arm custom-built environmental bucket and installed it on the crane. (See cover). The bucket digs with a level cut, and has overlapping side plates that prevent material from escaping into the water column as the bucket rises. Dimensions are: open length – 21 feet, open width – 26 feet, weight – 52,000 pounds, wire rope size — two inches.
