Accelerate your transhipment

At Nemag we work with transhipment companies all over the world. Time for us to lay down some of the most important things when it comes to transhipment.

Transhipment is the shipment of goods or dry bulk cargo to an intermediate destination, then to another destination. One possible reason for transhipment is to combine small shipments into one large shipment (consolidation) and/or to divide the large shipment at the other end (deconsolidation). High-performance transhipment usually takes place at on- or offshore transport hubs.

Trends and challenges

Apart from management issues on board, seaborne operations face the following challenges:

  • Operational: How do I avoid congestion and demurrage costs of ingoing and outgoing vessels due to slippage in ETA & ETD, availability of the installation due to bad sea state and other meteorological conditions?
  • Technical: How do I keep my installation going at open sea under severe conditions and without too much technical support?
  • Financial: As the handling rates are under pressure due to overcapacity in the dry bulk market, how do I increase efficiency and lower costs per tonne of transhipment?

 

Equipment at transhippers

Many high-performance marine transhipment hubs are equipped with four rope (grab) slewing cranes. The reason for choosing four rope cranes is significantly higher efficiency compared to, for instance, slow-moving, singleline derrick cranes equipped with slow- operating remote controlled or electro/ hydraulic grabs.

In most cases, these four rope cranes are standardized to a high degree with specific speeds and accelerations, depending on the make and type. Within these constraints, the productivity of any transhipment crane depends entirely on the productivity of the grab.

Any grab, regardless of type or brand, will have a given deadweight and payload. The general idea is that the lower the grab’s deadweight, the higher the payload and the higher the productivity. Right? Or is there more to it? Download our whitepaper about transhipment to find out.

Compare the grab glossary

Crane capacityIs the Safe Working Load of your crane in tons in grab duty, i.e. the total sum of grab dead weight and payload.

PayloadIs the nett load of cargo in the grab. Because it’s linked with the grab weight it will be filled in automatically.

Grab weightIs the Dead weight of your existing grab. Not sure? Check your grab manual, CE declaration, or on the ID plate on your grab.

Grab rope withdrawal lengthIs the length of the closing rope which needs to be pulled out in order to close the grab (not to confuse with the total reeved in grab rope length).

Not sure about the numbers?Check the grab manual. Don’t hesitate to contact us.
