Ship and Barge Unloading Systems

Ship and Barge Unloaders

All vacuum arms are NOT created equal! Most pneumatic vacuum unloading arms have evolved from cranes designed for vertical lifting and are fabricated from high-tensile steel. When these arms are under high loads and forces resulting from manipulation through dry-bulk powders they can fatigue and crack very quickly. FLSmidth uses Finite Element Analysis (FEA) and performs full kinematic studies to identify and strengthen stress points on the DOCKSIDER™ and KOVAKO® ship unloader arms during the design phase to prevent the arm from failing during operation.

All DOCKSIDER and KOVAKO ship unloaders have modern PLC control systems which control all of the unloading functions automatically using easy-to-navigate touchscreens. The control systems have built-in features to monitor operational status, process settings, historical production data, alarms and maintenance requirements. It can even simulate operating conditions and test the components and sub systems, ensuring that your unloader is ready to work when you are.

Clean operation – from the time it enters the vacuum nozzle to the time it reaches its storage destination, the material is fully encapsulated in a system of piping, hoses and vessels – making DOCKSIDER and KOVAKO ship unloaders among the most environmentally-friendly transfer systems in the industry.

The filtration system is either integral with the transfer kettles or in a separate filter vessel (for dual-pipeline or extra-high capacity applications). Pleated cartridges provide optimal cloth area in a compact design, and jet-pulse cleaning and a PTFE media coating offer maximum durability and efficiency.

Performance you need – GUARANTEED! With the industry’s continuing demand for increased capacity and for conveying multiple and diverse materials, constant research and development is critical. Only FLSmidth’s Pneumatic Transport group has a laboratory capable of analyzing various materials – over 160 to date – for the sole purpose of identifying the optimal design for their movement through a pneumatic conveying pipeline. Every DOCKSIDER and KOVAKO ship unloader is backed with a performance guarantee – and FLSmidth’s global reputation for superior quality and exemplary customer service.



DOCKSIDER™ – the most versatile and most advanced pneumatic ship unloader in the world! DOCKSIDER ship unloaders are custom-designed for your specific terminal application, with state-of-the-art technology developed by FLSmidth exclusively for the ship and barge unloading industry – offering unequalled performance, reliability and durability. For high-capacity applications, a separate vacuum filter receiver allows for continuous airflow and faster material transfer. Multiple discharge options, including pressure tanks, feeders and rotary valves allow for conveying a wide range of dry-bulk materials – even abrasive products such as alumina and coarse limestone. The system can even discharge through a Fuller-Kinyon™ pump – allowing for simple, low-pressure pneumatic conveying, or to provide a durable vacuum seal for material transfer to a dock belt conveyor. Starting with a range of four basic sizes, FLSmidth can supply the right DOCKSIDER ship unloader for any terminal – whether you’re unloading river barges or Handymax bulk vessels, and whether you’re conveying to an adjacent belt conveyor or through a 1,200 meter (4,000 foot) pipeline.

Dome Reclaim

FLSmidth’s Ful-Floor Dome Reclaim system provides cost-effective material reclaim. Airslide™ sections fluidize material in the main flow troughs in zones. The Dome Floor is divided into several “Zones” – One blower is dedicated to each zone. Product is reclaimed from the center first using one blower. Zone 1 is reclaimed next, then Zone 2, until empty. Product is reclaimed from the center first and symmetrically to the outside of the dome. Reclaim rates of 800 TPH and more are possible. Reclaim efficiency greater than 99% is achieved. Average power consumption is low.
