Serodino Delivers Mv. Kraken To TVA

Serodino Inc. recently delivered the 1,500 hp. mv. Kraken to the Tennessee Valley Authority.

The Super Tiger Class vessel is certified under Coast Guard Subchapter M rules. The 60- by 24- by 8-foot hull, with 5-1/2-foot draft, is constructed of half-inch plate throughout.  Deck and bulkheads are 3/8-inch.  Transverse framing is 5- by 3- by 3/8 inches on 24-inch centers.  The inside motor mounts are continued fore and aft as solid sheets to divide the hull into three collision compartments, three fuel tanks (9,500 gallons), engineroom, three water tanks, and six stern compartments.  All void tanks have high level alarms with bilge piping. 

A 110-gallon lube oil tank and a 110-gallon transmission oil tank are built into the hull.

Power consists of two Cummins QSK-19-M engines, developing a total of 1,500 continuous horsepower at 1,800 rpm., with Twin-Disc MG-5222 reverse and 4.03 to 1 reduction gears turning 5-inch sleeved shafts and 52- by 44-inchfour-blade propellers.  Two 40 kW John Deere MDDCA light plants furnish auxiliary electric power.

Skipper follow-up lever controls with backup separately activate four flanking and two main rudders.  The two hydraulic pumps are driven by electric motors.

Standard equipment includes navigation lights, one incandescent and one Xenon searchlight, 40-ton Wintech electric winches, Schuyler rubber towknees, perimeter fenders, shore power plug-in, and Fernstrum zero-knot coolers.

The superstructure is constructed of 3/16-inch plate with 2- by 2-1/2- by ¼-inch framing; main deck doors are watertight, and windows are aluminum with safety glass panes.  Spartan quarters are insulated, paneled, heated and air conditioned and have poured rubber flooring.

The first deck contains a 12- by 10-foot, a modest head with shower and a U.S. Coast Guard-approved marine toilet.  The second deck has storage space.  The pilothouse has full instrumentation and vessel control.  There is a 3-foot space below the pilothouse to make an eye level of 28 feet.

The vessel will enter service at TVA’s Gallatin Steam Plant on the Cumberland River.
