Cutter Suction Dredger Traveling Cylinder<\/h2>\n

A CSD has no propellers. It “walks” \u2014 pushing itself forward along the dredging cut one stroke at a time using spud piles and this cylinder. Stroke up to 9.4 metres per step. The longest-stroke cylinder in the CSD hydraulic system.<\/p>\n

How Does a Cutter Suction Dredger Move Without Propellers?<\/h2>\n
<\/div>\n

\"Cutter<\/p>\n

A cutter suction dredger does not have propellers for positioning. Instead, it “walks” along the dredging cut using a spud-carriage system \u2014 two steel spud piles driven into the seabed, and a set of traveling cylinders that push or pull the hull relative to the spuds. The traveling cylinder extends, pushing the hull forward by one stroke length (up to 9.4 metres). Then the forward spud is lowered, the rear spud is raised, and the process reverses. This step-by-step walking allows the CSD to advance precisely along the dredging lane, maintaining the cutter head’s position with centimetre accuracy \u2014 essential when dredging a navigation channel to a specified depth profile.<\/p>\n

The traveling cylinder is the main executive element of this walking mechanism. Its stroke length determines how far the CSD advances per step, and its thrust force determines whether the vessel can push against current, wind, and the reaction forces from the cutter head cutting into hard seabed material. Korea Ever-Power engineers each traveling cylinder for the specific CSD model within the offshore hydraulic cylinder<\/a> range.<\/p>\n<\/section>\n

Why 9,400 mm Stroke \u2014 The Longest Cylinder on a CSD<\/h2>\n
<\/div>\n

Every metre of stroke is one metre of forward travel per walking step. A 9,400 mm stroke means the CSD advances 9.4 metres per step \u2014 reducing the number of spud-shift cycles needed per hour and directly increasing dredging productivity. A shorter stroke (say 5,000 mm) would require nearly twice as many walking steps to cover the same distance, with each step-change involving a spud lift, repositioning, and re-planting sequence that takes 2\u20135 minutes of non-dredging time.<\/p>\n

\n
\n Longer stroke = fewer steps = more dredging time<\/strong><\/p>\n

On a 500-metre dredging lane, a 9.4 m stroke requires ~53 steps. A 5 m stroke requires ~100 steps \u2014 47 extra spud-shift cycles, each costing 2\u20135 minutes. Over a 12-hour shift, the longer-stroke cylinder can save 1.5\u20134 hours of non-productive time.<\/p>\n<\/p><\/div>\n

\n Manufacturing challenge at 9.4 m<\/strong><\/p>\n

A 9,400 mm rod must be straight to \u22640.1 mm\/m across its entire length \u2014 meaning total runout \u22640.94 mm. The rod is chrome-plated (or laser-clad), honed, and inspected on a dedicated long-stroke straightening and measuring bed.
