Dann Marine Repowers With Cummins Tier 3 Engines
Dann Marine Towing, LC., is a fifth generation family owned and operated tugboat company based in Chesapeake City, MD. The model-bow twin-screw tug Sea Coast was built at Rayco Shipbuilders in 1980 and is one of Dann Marine’s 18-tug fleet. She is 65 feet overall with a 24-foot beam and an 8.9-foot draft. She carries 16,000 gallon fuel and 5,000 gallons of water. One of many versatile tugs working in US waters of this class, she is registered for Coastwide Unrestricted. She can operate in push-mode with a pair of 20-ton Nabrico deck winches, each loaded with 110 feet of one-inch cable. She can also tow and has a Markey TTC-18 towing winch fitted with 1000 feet of one-inch cable. Until recently she was powered by a pair of 700-HP Cats turning into ZF TF4587 gears with 6.458:1 reduction. This May she has undergone a repower with the Cats out and a pair of Tier 3 compliant Cummins QSK19-Ms installed. These modern six-cylinder engines each produce 750 HP at 1800 RPM with a continuous-duty rating. The boat also got new gears with a pair of Reintjes WAF374 having 6.417:1 reduction. The same four-blade 63x76-inch stainless steel Rice propellers were maintained.
Tugs removed drifting barges
The tugs "Sea Coast" and "Eleen MaCalister" on June 24, 2013, removed two barges that broke away from their pier and struck the Jordan Bridge on the Elizabeth River in Chesapeake, and took them to the Perdue Farms Grain Wharf. Watchstanders at Coast Guard Sector Hampton Roads received a report at approximately 12:30 a.m. from the Chesapeake Police Department, stating two 260-foot barges struck the bridge. Watchstanders deployed a crew from Coast Guard Station Portsmouth aboard a 25-foot Response Boat-Small to investigate. Chesapeake police units also responded. There was no visible damage to the bridge, and river and road traffic remained open. Coast Guard Sector Hampton Roads inspectors were scheduled to conduct a follow-up inspection.
