Biomass is a relatively new type of cargo. The definition of biomass is still prone to the discussion and many terminal operators are facing challenges when this cargo arrives at their terminal.
There is a great variety in the appearance of biomass, varying from very easy to handle wood pellets to compacted and fermented wood chips, to undefined “forest products”.
Examples of dry bulk biomass cargo materials:
- Wood Pellets
- Wood Chips
- Agricultural Residues (e.g., corn stover, wheat straw)
- Olive Pits
- Palm Kernel Shells
- Sunflower Husks
Loading and unloading biomass requires a different way of thinking:
- Production in cubic meters instead of tonnes
- Covered storage
- Dedicated conveyor systems
- Minimising product degradation, especially important when handling wood pellets
- Specific storage and climate control to prevent combustion/gas emission
The choice of grab type is of significant influence on your productivity, unloading process and possible savings on the use of expensive trimming equipment. Most important, however: enhanced safety of your people; less trimming equipment in the hold, means improved safety for your people.
The best wood pellets grab
For handling Wood Pellets, the Nemag clamshell grab will be the preferred choice: environmentally friendly and closed shells with high payload and low deadweight will do the job perfectly.
The best grab for loading and unloading wood chips
For handling wood chips the NEMAG Orange Peel Grab (Cactus grab) can be chosen. This will however also lead to relatively high trimming costs during the intermediate and final stage of unloading. Cactus grabs of up to 55 cbm have been supplied and are in operation.
Most efficient grab for biomass
To cut on trimming costs, the NEMAG Scissors grab is the most ideal choice; efficient unloading though the ship hardly without the use of expensive trimming equipment. Scissors grabs of 60 cbm are in operation to full satisfaction.
