Bespoke propeller helps barge transit the Wye

Bedfordshire UK based propulsion specialists Clements Engineering responded to an unusual call recently when a 38m long Dutch barge needed to negotiate the River Wye from its resting place for the last 25 years.

The Wye Invader needed to get down the River Wye from Hereford to a boat yard on the Severn. It is the largest vessel known to have navigated the many twists turns and bridges along the way. The barge was fitted with a 1957 Volvo engine rated at 96 hp and the owner was concerned about being able to stop it with a percentage of the propeller out of the water.

He contacted Clements Engineering MD Paul Williams and two weeks later, following some calculations and the application of many years’ experience, Clements had provided a specially made propeller with a greater pitch than normal for such a vessel. Helping to provide very precise steerage with the limited water flow, it enabled Wye Invader to negotiate the difficult river and reach its destination.
