An increased number of flow paths results in an increased number of breaching surfaces.

An offshore crane tower system for use on a vessel with a moonpool includes a tower structure whichextends in a vertical direction and is for placement on the vessel adjacent to and/or above the moonpool; a crane with a hoist system able to lift and lower a load; and a crane support at an upper portion of the tower structure. The crane can selectivelyconnect to the crane support so that the hoist system of the crane can be used to lift and lower a load through the moonpool.
A blade for an impeller comprises a blade with a front portion with a leading edge and a trailing portion with a trailing edge joined by spaced apart pressure and suction sides to form an exterior blade surface. The blade pressure side is formed from an outer envelope of a first blade profile aligned in a first position; and at least a part of the front portion of the blade suction side is formed by rotating the first blade profile around the leading edge to match an angle of the incoming flow at a lower flowrate condition of the impeller.
An overflow system for a hopper dredger comprises an overflow tube; an inlet for taking in head water from the hopper; and a collector to collect the flow of head water entering the inlet and guide the flow to the overflow tube. The collector comprises a substantially horizontal top portion which delineates a top of a flowpath for head water into the collector to ensure substantially radial flow into the collector. At least one of the overflow tube and the inlet is adjustable for controlling flow into the overflow system.
A measurement device for performing measurements on a mixture of water and collected material includes a pipe section through which the mixture can be guided. The pipe section includes a window. The measurement device further includes an image capturing device arranged to capture an image of the collected material through the window. The image can be used to determine a grain size distribution of the collected material, which can be used to optimize the collecting process.

METHOD OF AND SYSTEM FOR INSTALLING FOUNDATION ELEMENTS IN AN UNDERWATER GROUND FORMATION
The invention relates to a method of installing foundation elements, in particular (mono)piles (2) having a diameter of five meters or more, in an underwater ground formation (3) comprising the steps of lowering a leader (8) from a surface vessel (4) with at least the tip of the leader (8) into the water, and lowering a foundation element (2) and/or a noise mitigation screen (5) along the leader (8).
