1,500 m3 New Build Trailing Suction Split Hopper Dredger

This is a 1,500 m3 New Build Trailing Suction Split Hopper Dredger is a kind of multi-purpose vessel very specialized over all in sand dredging, and also excellent for regeneration of beaches. It is able to carry out other type of maritime works, like landfills and others marine rearrangements. This vessel is classed by BV (Bureau Veritas) reached during construction and the Class Notation is BV I âœ Hull * MACH Split Hopper Dredger, Unrestricted Navigation, dredging over 15 miles from shore.

Available domestic facilities for up to 14 crew members, all equipment - inclusive machinery refrigeration, etc.- have been sized for operating in tropical conditions with air temperature up to 40 degrees C and Engine Room temperature up to 50 degrees C. During dredging activity, it is able to load the hopper with sand with a mixture density of 1.200 kg/m3 in less than 90 minutes approximately, and unload it in less than 50 minutes approx.

Delivery depends on work in process, but usually 17-months, or 15-months with overtime.
