Stowage As A Profit Centre - Pt 3

Finally we can get down to the business of actually stowing our ship. Below are two examples where the first bay is completely utilised and the second where it could definitely be improved.

This would be a bay that is considered to be fully utilised:

See diagram fig.11 (Orange is first Port of Discharge, Blue is the second Port of Discharge)

Of the nominal capacity of it is comprised of the following:

45 fully utilized reefer slots
Two tiers of high cubes underdeck without slot loss
9 Tiers on deck with good vertical weight distribution
Hazardous cargo is grouped together underdeck
45ft units grouped together to minimize lost slots
Empties only in the highest 3 tiers (reduced overstows)
OOG pieces loaded together to minimize slots killed
OOG killed slots charged to shipper is 20 TEU in total
Actual OOG slots killed is only 16 TEU in total
Reduced height tower in the centre for better productivity

Actual TEU’s charged for = 572 (due to OOG combining)

Therefore, this stow actually exceeds the nominal TEU for the bay by ensuring that every slot is properly utilised.

This would be a bay that is NOT considered to be fully utilized:

See fig.13 (Orange is first Port of Discharge, Blue is the second Port of Discharge)

Of the nominal capacity of it is comprised of the following:

Only 36 reefer slots used
9 reefer slots lost due to hazardous container on deck
Three tiers of high cubes underdeck that voids one whole tier
8 Tiers on deck due to poor vertical weight distribution
Hazardous cargo is scattered underdeck and on deck
45ft stowed horizontally prevent loading 40ft on top
20fts stowed horizontally are not making full use of stackweight
OOG pieces not loaded together to kill excessive number of slots
OOG killed slots charged to shipper is 10 TEU per piece
Actual OOG slots killed are 44 TEU in total

Full height tower in the centre will reduce productivity

Therefore, this stow has 480 TEU that are chargeable and so is well below the nominal TEU for the bay by ensuring that every slot is properly utilized. 88 TEU on this single bay is wasted space.
