Propulsion Update

Veth-Jet Bowthruster

From Hyde Products

To Be Installed On 'Mississippi

Schematic drawing of the Veth-Jet bowthruster's horizontally mounted propeller unit.

Hyde Products, Inc., of Cleve- land, Ohio, has delivered a Veth-Jet

Bowthruster Model 2-K-1000 to

Trinity Industries' Moss Point,

Miss.-based Halter Marine shipyard for installation onboard the M/V Mis- sissippi, a multipurpose towboat that will be delivered to the Mem- phis District of the Army Corps of

Engineers later this year.

The vessel will be used by the

Mississippi River Commission and will be equipped with a public con- ference room seating 200, accom- modations for up to 78 passengers and quarters for commission mem- bers and crew.

The Mississippi will be able to push or tow up to sixteen 200-ft barges and will also be used during high and low river inspections.

The 241-foot vessel will have a beam of 58 feet, depth of 12 feet, 6 inches and a design draft of 8 feet.

Power is to be supplied by three diesels with a total of 6,100 hp. It is reported that the Mississippi will be the largest diesel-powered towboat ever built in the U.S.

The vessel's Veth-Jet thruster sys- tem, manufactured by VethMotoren

B.V., the Netherlands, includes a two duct thruster for port or star- board flow; thruster housing with hydraulic steering motor and three- blade propeller; complete hydraulic package including pump, motor and tank; and, complete electrical pack- age with switchboard and local and pilot house steering panels.

The Veth-Jet is a straightforward, high reliability and low maintenance system. The fixed-pitch, horizontally- mounted propeller is driven by a right angle spirally cut bevel gear. Water is drawn from under the vessel's hull through a rotatable elbow around which a specially designed deflector guide ensures a minimum power loss.

The thruster's deflector guide is rotated by a hydraulic steering motor using a 24-volt signal.

The thruster discharge is 90 degrees from the inlet with no restrictions, resulting in higher efficiency and lower noise. Full thrust can be obtained at drafts of only 1/2 meter (1.64 feet).

With over 420 units delivered, the Veth Jet is one of the most popular thrusters used in Europe.

Veth-Jet bowthrusters are avail- able in a range of sizes from 150 to 1,500 hp with two, three and four outlet ducts which allow a full 360-degree azimuthing, propulsor/retarder capability.

Diesel, hydraulic or electric drives are available.

Hyde Products, a long estab- lished manufacturer of ship's deck machinery and steering systems, is the North American agent for

Veth Motoren's Veth-Jet bowthruster.
