Colombo Dockyard was the
best repair option for China
Harbour Engineering Co. Ltd.
China owned trailer suction
Dredger Jun Hai 2 (GRT
10,751) was due for her dry
docking and survey repairs.
This dredger Jun Hai 2 was
deployed in the Colombo
South port development
project in Colombo.
Colombo Dockyard has been
attracting major dredger
operators globally such as
Dredging International,
Belgium, Van Ood Ship
Management, Netherlands,
Dredging Corporation of
India, Dharti Dredging and
Infrastructure Ltd. India
for their repair
requirements.
The proven past track record
of Colombo Dockyard on
handling similar or more
complicated projects
successfully helped the
owners to place their
confidence in Colombo for
the repair requirements of
the sophisticated trailing
suction dredger repairs, as
this was the first
experience with the Colombo
Dockyard for this client.
The owners have planned the
lay-up repairs during
monsoon period, where the
dredging activity is slow
and they can release the
vessel for a major lay-up.
During this call the owners
were preparing the vessel
for her first dry docking
survey repair requirements.
The work extensive scope
package consisted of:
Port and Stbd Rudder removal
and renewal of Controllable
Pitch Propeller Blades
.

§ Renewal of Port and Stbd
Dredge suction sleeve and

§ Modification of Jet

§ Full blasting of hull and

The critical work scope was
executed by the steel
department on the Kort
Nozzle liner renewal, the
condition of the existing
lining was in bad state. The
bottom door repairs were
carried out meticulously
meeting the owner’s
requirements. The owners
were very happy with the
workmanship, speed of repair
and the professional
approach taken by the yard
to tackle the entire project
successfully. The repairs
were carried out meeting the
requirements of China
Classification Society. The
vessel went on back to her
operational duties soon
after completion of repair
work. Taking this business
relationship further the
owners are looking at
Colombo Dockyard as one of
their preferred repair
centres for the fleet
operating in the region.
