Bulk Material Handling

APTIM has vast experience with specialized bulk material handling systems, especially with the transfer of materials and the equipment associated with plant processes. 

Our experience has shown that a combination of methods including DEM (Discreet Element Method Modeling), calculations, practical design, and best-practice dust collection principles that are required to arrive at each facility using the metrics that the plant has determined to be of the greatest value. We have used DEM simulation software to help successfully design hundreds of transfers which yielded positive results such as center loading; reduction of dust, belt wear, and noise; and increased chute life expectancy.  Our product experience includes:

  • Whole grains, Dried Distillers Grain (DDG)
  • Meals
  • PRB, eastern, and lignite coal
  • Potash and ash
  • Limestone and gypsum,
  • Heavy metals, iron ore bauxite, alumina
  • Biofuels and other materials


APTIM has engineered, constructed and managed many of the largest and most logistically challenging projects in the world.  Whether the challenge is corresponding dredge depths and extra high deck elevations in poor soil conditions or designing a transfer terminal and handling project logistics, our staff of experts can provide a full range of construction and program management services.  Our range of staff expertise specializes in design and field experience in engineering, marine terminals, and facilities.  Our terminal experience includes bulk material, grain, container, general cargo, rail ferry and energy.  Our professional experts include:

  • Marine structural engineers
  • Civil engineers
  • Geotechnical engineers
  • Mechanical engineers
  • Electrical engineers
  • Environmental engineers
  • Construction engineers
  • Program/project managers

Design Services

APTIM provides feasibility studies, project development and engineering throughout all of the following phases:

  • Planning, estimating and preliminary engineering
  • Existing facility assessments
  • Structures and building design
  • Program and construction management
  • Port terminal planning, design and engineering

Grain Terminal Services

Serving as the owner’s representative for construction and contract management, we know the key to a successful project is efficiently implementing practical design in the field and providing a single continuous link from conceptual design to an operating solution. Utilization of our management manpower provides savings in both project costs and time. Our construction managers are involved in all aspects of the project from conceptual layout and permitting to commissioning and start up. We offer grain terminal services in the following areas: Complete engineering layout and design details for new systems or retrofit systems

  • Dock design, repair engineering and assessment
  • Maintenance and shutdown/turnaround millwright work
  • Bulk material equipment selection and evaluation
  • Dust generation and product degradation reduction through DEM transfer flow analysis
  • Underwater dock inspection and 3D modeling using LDAR (side sonar)
  • Environmental air emission testing, evaluation and resolutions
  • Environmental site assessments and permit preparation
  • Energy sustainability
  • Laser cloud scanning
