Dredge Yard delivered
two bows coupling for the size of 600mm for European dredging company. Those
bow couplings will be used on two existing dredgers for the quick coupling and
dis-coupling.
They were designed, produced and tested for working
pressure of 10 bars in Dredge Yard’s facilities in Dubai. These couplings are provided
with a hydraulically operated locking system for quick as well as easy locking
and releasing of the discharge lines offering the possibility to reduce time between phases
of the dredging activity.
The bow couplings are
equipped with duplex ball to prevent rust and achieve wear performance. To
clamp the ball in the bow coupling casing two half-moon bars are provided
around the gland enforced by one hydraulic cylinder. Inside the ball a wear
resistant ball liner is provided to increase the life time of the coupling.
Moreover, two hydraulically operated locking pins are
provided for securing the locking clamps during high pressure discharging,
making them more reliable during operations. In addition, major parts which are
affected during operations can be easily repaired or replaced.
With Dredge Yard’s improved locking system design, it’s more reliable, less
time consuming and hence, cost effective.
They are available in a
wide range of sizes from 400 mm to 1200 mm with working pressure between 10 to
30 bars.
