The Hopper Dredge


Book Description

Hopper dredges are designed to vacuum material from the sea floor through drag arms that load the material into the hold of the vessel. The cargo of mud, or sand, can then be transported to either an ocean disposal site, where the material is dropped to the bottom through openings in the bottom of the hull, or at an upland site such as a beach, or reclamation, where the material is pumped ashore by the ship. This method is most suited when excavating loose material from open areas for delivery to a distant disposal location. These vessels are generally certified to sail in coastal or ocean waters and are suited for working in rougher sea conditions beyond those suitable for other dredging plants.










Construction of Marine and Offshore Structures


Book Description

The leading authority in the field offers a unique and comprehensive treatment of the construction aspects of offshore structures, rather than the more commonly addressed design considerations. Extensively updated, this second edition provides a new chapter on extending offshore technologies to inland waterways and emphasizes recent advances-including floating structures, deep-water structures, ice-resistant structures, and bridge foundations. Construction of Marine and Offshore Structures details all the particulars of building in a marine environment, including construction equipment, marine operations, installing piles, pipelines, and cables, steel and concrete offshore platforms, and underwater repairs. Construction of Marine and Offshore Structures provides an essential reference to engineers in the oil and service industries and to marine construction planners, designers, and contractors. New in the second edition: How the physical environment and geotechnical conditions affect construction Increased attention to protecting the natural environment and compliance with regulatory provisions Recent developments in positioning, instrumentation, and underwater inspection, plus a new section on concrete and steel floating structures and installing permanent moorings Expanded treatment of deep water bridge piers as well as locks and dams on major rivers.
