Home' Work Boat World : September 2009 Contents Kochi Refineries Limited (KRL), situated
in Cochin, India, is undergoing a
The 800-tonne vacuum gas oil reactor
(VGO reactor) for the refinery's expansion
was built in China and transported by road
to the Port of Dalian, then shipped to
Cochin on the heavy lift ship 'Maria'.
The 37-metre long, 5.2-metre diameter
reactor is the biggest single piece of
machinery to have been handled in the
country. Once the reactor reached Cochin,
it had to be transported a distance of 25
kilometres from the port to the refinery,
but the narrow roads, sharp curves and
light bridges of Cochin could not
accommodate the outsized, heavy reactor.
LOTS Shipping, based in Kochi, came up
with a water transport solution for the
reactor's journey to the refinery involving
the construction of a purpose-built barge,
the design of which would take into account
the critical water depth and air draught
restrictions involved in negotiation of canal
routes. The total distance of 25 kilometres
by water from Cochin Port to the refinery
involves multiple road, rail and footbridge
crossings, including 20 bridges and pipe
lines across Champakkara Canal which have
limits with respect to both width and air
draft. Champakkara Canal also has several
sharp curves and shallow patches.
The build order for the barge was placed
with Master Shipyard of Edakochi, Kochi.
Master Shipyard has a diversified portfolio
of successfully built craft operating in
different parts of the world. These include
650-tonne general cargo, self-propelled
barges, 1,800-tonne self-propelled barges,
550-tonne tanker barges, yachts, work
boats, crew boats, jack up barges and more.
The keel was laid for the special purpose
barge at Master Shipyard on February 18,
2009. The barge was built under survey to
the Indian Register of Shipping (as a
warranty requirement) and involved the
fabrication and erection of about 300
tonnes of steel.
The barge has an overall length of 54
metres on a 12-metre beam and a depth of
three metres and is double-skinned all
round. Additional strengthening was
applied to the areas where the reactor
cradle was to rest.
The fabrication involved about 200
workers labouring on a twenty-four hour,
seven-day-a-week basis. Master Shipyard
delivered the barge in just over 70 days and
the barge was launched, classed and
certified just two days before the arrival of
the heavy lift vessel at Cochin on May 16.
LOTS Shipping, with its extensive
knowledge of inland water transportation,
took up the inland water logistics between
Cochin Port and Irimpanam -- a site close
to the refinery, from where the reactor was
to be transported by road.
A thorough survey of the complete
route was carried out, checking and
recording depths throughout the canal
length, recording air draughts at bridges at
various tidal conditions and the effects of
tides and currents.
The barge transport of the reactor,
which commenced on June 3, took place
only during daylight hours in three stages
(depending on the tides). It took three days
to reach the destination, crossing a total of
20 bridges and pipe lines with width and
air draught restrictions and navigating
several sharp curves and shallow patches.
The barge carrying the reactor was
handed over successfully on June 6.
