Definitions
- the present invention relates to a method for operating a plain suction dredging vessel, the vessel comprising a suction system with at least one lower suction pipe at a respective suction location.
- Such a method is known from US 6499239 wherein is disclosed a method for extracting and grading or sizing sand, gravel or a mixture thereof, from a pit formed in untouched ground. Liquid is sprayed into the ground, resulting in a fluidized state in the ground, in which state sand or gravel with a relatively high relative density and/or relatively large dimensions moves downwards, and sand or gravel material with a relatively low relative density and/or relatively small dimensions moves upwards. Thus a pit is formed in the ground which contains fluidized sand or gravel, in such a manner that a layered state is obtained.
- the layer of sand or gravel with a specific relative density and/or size is sucked out, while the remaining fluidized material remains behind in order to stabilize the wall of the pit.
- the material which has been sucked out is fed to a grading device or sizing device.
- EP 0078563 A1 relates to a method for suctioning submerged bottom material and a system for carrying out said method.
- the suction tube is anchored in the bottom while the vessel is anchored by anchoring means such as a cable 33 running e.g. to an anchoring point onto the dry land and a cable 34 running from a winch 35 e.g. to an anchoring buoy.
- US 4 445 290 A relates to an appliance for dredging the bottom of a body of water.
- the appliance is anchored by two pivoting dredging cables 22, 23 anchored at the bottom 16 of the body of water.
- the bucket wheel is not suitable for any anchoring function.
- US 4 386 473 A relates to a method for the recovery of sediments from the bottom of the sea by means of a freely suspended suction pipe provided on one end with a suction mouth.
- the suction mouth is anchored at the bottom of the sea while the ship maintains directional alignment with respect to the vertical axis by using a drive means instead of the suction pipe which is freely suspended.
- JP 2006 104728 A relates to a sand suction mechanism for a sand removal facility.
- the suction mouth is anchored in the ground as seen in fig. 9.
- the suction pipe is coupled with the vessel by a flexible lifting device which is unsuitable for force transmission which is required for anchoring the vessel.
- Pain suction dredging refers in general to a method for suctioning submerged bottom material with the aid of at least a suction tube connected to a vessel, whereby said suction tube is lowered from said vessel in an inclined or vertical position, and an underpressure is created in said suction tube for suctioning a mixture of bottom material and water through the tube via one or more suction openings near the lower side of the suction tube, whereby eventually the suction openings are gradually lowered under the bottom surface such, that by suctioning the bottom material an excavation or trough is formed into the bottom.
- a plain suction dredging vessel is usually a non-propelled vessel which is held in position by means of 4 to 6 anchors located at ample distance from the vessel.
- the mobilisation -and demobilisation time for a plain suction vessel is largely determined by the time required to place the anchors before commencing the work and the time to bring in the anchors when stopping the work.
- the long mobilisation -and demobilisation time increases the down time of a plain suction vessel which is undesirable.
- the invention aims to solve at least partly a problem associated with known methods for operating a plain suction dredging vessel.
- Another object of the invention is to improve a method for operating a plain suction dredging vessel such that at least the up time of the vessel is increased.
- Yet another object of the invention is to provide an alternative method for operating a plain suction dredging vessel.
- this is realized with a method for operating a plain suction dredging vessel, the vessel comprising;
- the anchoring of the vessel is via the at least one lower suction pipe section only. This even more simplifies the anchoring, and reduces part count. It will be clear from the wording "anchoring the vessel” that it is implied that any coupling means for coupling the vessel with the lower suction pipe as well as the suction pipe itself must be suitable to withstand anchoring forces for anchoring the vessel.
- the suction location and the anchoring location are substantially vertically aligned. This enables use of the suction openings to facilitate the application of placing the anchor in the bottom by jet water through these suction openings. In addition, efficient use is made of pipe section material.
- the longitudinal axis of the at least one lower suction pipe section is aligned with the anchoring location.
- the at least one lower suction pipe section comprises an anchoring portion
- the method comprises the step of driving the at least one lower suction pipe section for the anchoring portion at least partly extending in the bottom at the suction location.
- the driving of the at least one lower suction pipe section comprises one or more of the following steps, hammering the lower suction pipe, and water jetting at the suction location and sucking. This even more enables improved control of the anchoring of the vessel during plain suction dredging.
- the method comprises a step of driving the vessel to take a position regarding wind and current conditions. This reduces possible loads to the anchor. This is important since a suction pipe line is normally not designed to anchor a vessel. It is noted that driving here means driving the vessel to take or maintain a position such that the load to the anchor is optimal.
- the driving of the vessel comprises rotation of the vessel around the longitudinal axis of the lower suction pipe. This enables reducing the required anchoring force for the anchor portion of the lower suction pipe.
- the vessel comprises a propulsion system for driving the vessel to take a position regarding wind and current conditions. This even more enables reducing the required anchoring force for the anchor portion of the lower suction pipe.
- the invention further relates to a plain suction dredging vessel according to claim 8.

- the at least one lower suction pipe section comprises at least one suction opening for sucking sludge and the anchoring portion in use extends below the at least one suction opening.
