A sluiceway device for a hopper barge has an elongate main body defining a discharge channel. The elongate main body has a plurality of openings. The elongate main body may be configured to be disposed atop a hull of the hopper barge and configured to receive dredging material placed in the hopper barge. The sluiceway device may also have a discharge pump. The discharge pump may be in communication with the discharge channel. The discharge pump may be further configured to pump the dredging material from the discharge channel to a disposal area outside of the hopper barge.

The invention relates to a sheet (1) to be placed in relation to a split barge (100) for encapsulating a bulk of material (101) to be dumped when the bulk of material is released, the sheet comprising a material containing portion (4) and at least one material free portion (3) extending from at least two opposed sides of the material containing portion, wherein that the immersed sheet encapsulating the bulk of material comprises an encapsulated body (20) encapsulated by the material containing (4) portion and a self-closing portion (22) being at least a part of the material free portion (3) both extending from an assembly point (21), wherein a closing length of the self-closing portion (22) correspond to at least 5% of the circumventing length of the encapsulated body (20), the circumventing length extending from the assembly point (21) to the assembly point (21). The invention further relates to a method of encapsulating a bulk of material by means of a sheet.

A tug holding block for coupling a tug and a dredge includes a tug receiving portion configured to attach to the tug, ensuring a secure and stable connection. The tug holding block includes a pivotable coupling that facilitates attachment to the dredge, allowing for flexible movement and alignment between the tug and dredge during operation. The dredge may include a trailing suction hopper dredge having a split hull hopper scow configured to split relative to the stationary tug holding block. This configuration enhances the operational efficiency and maneuverability of the tug and dredge system, providing a reliable and adaptable solution for maritime applications. A dredging system including the tug holding block, a dredge, and a tug is provided along with a method of dredging using the dredging system.
