Damen screening installation assembled

The screening process is vital to controlling the required grain size of a hopper load and the new design has several features which are aimed at reducing maintenance, and an undisturbed loading process. The wear and tear ratio of all components in contact with aggregates is a well-known and costly fact. The new screening installation has been designed to last with flow direction optimization, specially added wall thickness where required, rubber lined components such as the loading chutes etc.

Mark Williams, fleet engineering manager at CEMEX UK Marine, stated CEMEX were looking forward to the increased operational efficiency and the modular construction that would dramatically reduce maintenance time and so enhance the efficiency significantly.

Easy to move

Components such as the screening decks can be dismounted within a quarter of an hour; this action can be done alongside the quay allowing a quick exchange of the screening decks which can be later serviced in the workshop. Most components such as both screening decks, delivery chutes etc are exchangeable.

Other design features include the substantially increased screening surface. Compared to previously available loading towers the surface has doubled resulting in improved cargo quality and reduced loading time. Rejected spoil is no longer discharged over the side, but leaves the system through the vessels bottom reducing vessel plume and the design snugly fits the restricted deck area available.

The installation will be dismounted to be shipped from Rotterdam to the Damen yard in Galati, where the MAD3500 is being constructed. Due to the plug ‘n play design, the final installation on board will be done swiftly.
