Vosta LMG Launches Universal Mk3 Bow

Tuesday, September 09, 2003
Gone are the days when in order to enable coupling of the floating discharge line, it used to be necessary that the bow coupling installations on the dredges were of the same make. With the universal VOSTA MK3 bow coupling installation this has changed.

Currently dredging contractors work with conventional VOSTA installations (MK1 up to MK3) and installations of other manufacturers. With the new universal bow coupling installation it is not only possible to couple a male part of VOSTA make – but also male parts of other manufacturers.

To make the compatibility possible, VOSTA LMG had to replace the spring-ring system with a segmented ring system. Much like the spring-ring, the segmented ring can be increased and reduced in diameter size via the use of a hydraulic cylinder. A second cylinder can lock the segments of the segmented ring in place.

Besides the interoperability an additional advantage of the segmented ring is that, in respect to conventional systems, the surface, which carries the male part is significantly increased. This improvement causes the coupling to be even more robust than before.

In August 2003, VOSTA LMG delivered the third universal VOSTA MK3 bow coupling installation. This installation will be assembled onto a 1,500-cu. m. Trailing Suction Hopper Dredge for Vietnamese customer Waterway Dredging & Construction Company.
