Capacity in terms of full (standardised measure is 14 tonnes/TEU) containers will be around 500 TEU. Capacity of the vessel will be ca.700 TEU-it means 700 x 20 feet (6-metres long) containers, without regard for stability and permissible stacking weights. Hatch covers are not lifted-on pontoons but hinged lids operated by hydraulic pistons and rolling on wheels to the fore and aft part of hatch-way. The vessel depicted is actually multipurpose general cargo vessel suitable for carrying containers, not a pure container-ship.
