A..P. MOLLER-MAERSK GROUP Berthing – What changes? Positives Large operations with high crane intensity Increasing berth productivity and hence Terminals Berth Capacity Quick turnaround resulting in better berth utilization Negatives Large vessel requiring more time to berth / depart PS type taking 2 hours from pilot to gangway is set A / G / S taking 1 hour from pilot to gangway is set Occupying more quay as using minimum 2 sets of bollards for head / stern lines PS type occupying 500 meter quay (400m vessel + 2*50m) A / G / S type occupying 410 meter quay (350m vessel + 2*30m)

A..P. MOLLER-MAERSK GROUP Maersk Line PS-class vessel (11.000 TEU) compared to: A /G /S-class, Panamax D-class, WAFmax T-class Average horisontal travel distance from mid quay: PS: 28m + 3m + 15m = 46m A / G / S: 21.5m + 3m + 15m = 39.5m Panamax: 16.5m + 3m + 15m = 34.5m WAFmax: 13.5m + 3m + 15m = 31.5m

A..P. MOLLER-MAERSK GROUP Maersk Line PS-class vessel (11.000 TEU) compared to: A /G /S-class, Panamax D-class, WAFmax T-class Average vertical travel distance from quay level: WAFmax: 11.5m + 5.7m = 17.2m Panamax: 17.0m + 5m = 22.0m A / G / S: 19.0m + 8.0m = 27.0m PS: 28.4m + 17.3m = 45.7m

A..P. MOLLER-MAERSK GROUP Maersk Line PS-class vessel (11.000 TEU) compared to: A /G /S-class, Panamax D-class, WAFmax T-class Modern cranes have following operating speeds: Trolley travel speed: 240 m/min or 4 m/s Hoisting / Lowering: Between 90 m/min & 180 m/min or average 2.5 m/s Difference in average travelling based previous data & considering WAFmax as standard: Vessel Type HorisontalVerticalTotal extra time/move Total cycle time Resulting GMPH msecondsm Seconds PS46.03.62539.08.7224.69144.6924.9 A/G/S39.5227.03.9211.84131.8427.3 Panamax34.50.7522.01.925.34125.3428.7 WAFmax31.5017.20012030

A..P. MOLLER-MAERSK GROUP Is this productivity loss a fact? The answer is no, not as dramatic as it is shown The cranes work for long times in the same position The hatchcover / container ratio dramatically drops More chances to use already stowed containers to steady container being loaded Vessel doesn’t move, heel or trim easy
8
A..P. MOLLER-MAERSK GROUP Systems Vessel configuration in systems Too wide - 22 rows where system only allowed for 20 Too many tiers under deck Workqueues Very large bays containing several hundred containers causing system problems if transferred in one queue Very large blocks difficult to compensate if needed Processing time for EDI files and strain on system Deadlines should be reconsidered in view of the number of moves the vessel has Bayplans
9
A..P. MOLLER-MAERSK GROUP Systems - Bayplans become a challenge (A4)
10
A..P. MOLLER-MAERSK GROUP This is why! (A4)
11
A..P. MOLLER-MAERSK GROUP Ship to Shore Cranes - Lifting height Lifting height Crane specific limitations Additional factors to consider when planning Not possible to use safety cages in all positions / with all cranes
12
A..P. MOLLER-MAERSK GROUP Outreach Outreach Increased boom lenght Increased cost Increased wheel load Are 22 rows enough?
13
A..P. MOLLER-MAERSK GROUP Hinge point of boom Hinge point Will the raised boom touch the bridgewing? Can the cranes pass the bridge? If the vessel has to heel it takes time – a long time! Do we need a different crane design? The 45 degree booming is not enough

A..P. MOLLER-MAERSK GROUP Thank you for your attention
