Design

The minesweepers of the Borndiep-class were equipped with mechanic, acoustic and magnetic sweepers.[5] The magnetic sweeper consisted of two cables through which electricity would pulse and as a result would create a magnetic field that would detonate magnetic mines.[6][7] As acoustic sweeper it had an electric hammer clock that would be thrown overboard to create vibrations which resulted in the destruction of acoustic mines.[8][9] The mechanic sweeper consisted of a cable on each side of the ship with at the end of the cables a floater that would hit a mine to make it detonate.[10]

Service history

The Borndiep-class was active in the North Sea after the Second World War to cleanup mines that were laid down during the war.[11][12][13] Between 16 and 25 July 1954 several minesweepers of the Borndiep-class took part in the NATO exercise Haul.[14][15]
