Self-Unloaders and Transshipment Systems

Self-unloaders got their start over 100 years ago on the Great Lakes of North America, EMS-Tech Inc.'s back yard and still the area with the highest concentration of self-unloaders.  Today, the vast majority of self-unloading ships and transloaders are built in China, and EMS-Tech Inc. has responded to this development through our Wuxi Site office for local inspections, equipment sourcing, site advisory services during assembly and installation, and commissioning services.

Self-unloaders and transshipment systems can now be found all around the world, and discharge capacities have been steadily increasing.  Self-unloaders are an excellent match for minimal shore based receiving systems, where the cargo is discharged either on the dock or into a receiving hopper with a conveyor based in-haul system.  Some self-unloaders are specially fitted with offshore rock laying systems to protect underwater cables and protect offshore oil platforms.

Transshippers are becoming more and more popular, especially in developing countries, as they can transfer cargo without the need to build expensive quay side terminals.  Transshippers can perform lightering operations on fully loaded ocean going vessels to enable them to dock, or take cargo from shore through barges, and load larger vessels just offshore.  This way, Cape Size and larger vessels can take advantage of economies of scale without the need for expensive dredging operations.

The EMS-Tech Inc. Marine Group is comprised of a mix of dedicated engineers, technologists, technicians and support staff.  With all the different projects we have successfully completed, and the repeat work we have had from clients who keep coming back, we can guide you through alternative designs which will meet your precise demands.
