Efficient Handling of Bio mass

Bio mass is a relative new type of cargo. The definition of bio mass is still prone to discussion and many terminal operators are facing challenges when this cargo arrives at their terminal.

There is a great varity in appearance of bio mass, varying from very easy to handle woodpellets to compacted and fermented wood chips, to undefined “forest products”.

Handling bio mass requires a different way of thinking:

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 hoewever: enhanced safety of your people; less trimming equipment in the hold, means improved safety for your people.

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.

For handling wood chips the NEMAG cactus grab can be choose. This will however also lead to relative 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.

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 have been manufactured and supplied and are in operation to full satisfaction.
