DRY DOCKING
Governed by maritime rules under the International Maritime Organisation (IMO*), all merchant ships are
required to be docked twice during a 5-year period of active operations. This is to assess and maintain
the sea-worthiness of the ship which is exposed to corrosion and fouling* due to constant contact with
seawater.
Excluding extraordinary renovation works, the whole dry docking process usually takes about 2-3 weeks.
Dry docking is planned in advance so as to ensure that dispatch of our ships are to countries that can
offer economical costings.
