Emergency Drydock of G.T.S Infinity at Victoria
Shipyards
In
the demanding world of ship repair, companies are constantly faced
with requests that are both challenging and demanding.
Such was the case on June 6th when with a simple phone call from
Senior Vice President, Fleet Operations, Rear Admiral Argyropoulos
advised Victoria Shipyards (VSL) their luxury cruise vessel, named
G.T.S Infinity, had developed a mechanical problem, with one of
it's two, 'Mermaid' propulsion units. He explained although the
vessel was sailing without any problems, it would be prudent to
drydock it, for a complete examination and repair of the starboard
propulsion unit. Carrying out this repair would ensure a continued,
trouble free, 2001 Alaska cruise-operating season. This request
quickly turned into one of the biggest logistical challenges VSL
has ever faced.
A sequence of events unfolded very quickly during numerous in-house
meetings where several scheduling problems were identified and solutions
found. The first one included finding a suitable time frame to drydock
the vessel. The operating location of Victoria Shipyards is the
1200-foot (ft.) Esquimalt Graving Dock located in Victoria on the
southern tip of Vancouver Island. VSL is the only drydock on the
West Coast of Canada with the capacity to accommodate the G.T.S
Infinity. BUT the drydock was already utilized for the multimillion-dollar
refit of the HMCS Protecteur, which was in its third month of a
six-month drydocking period. One can imagine the concerns of the
Department of National Defense, when VSL requested permission to
remove their vessel from the drydock. VSL's technical team quickly
verified vessel condition and determined what measures had to be
performed to ensure a safe float off condition. These calculations
were remitted to the Senior Project Officer in charge of the HMCS
Protecteur program for approval. Once that was received, VSL immediately
commenced operations of closing up the vessel in a timely fashion.
The HMCS Protecteur had numerous openings cut into the hull to
allow access to equipment being removed from its machinery spaces
for repair and overhaul. Heavy equipment was also removed from various
locations throughout the vessel, causing the ship's stability condition
for undocking to be compromised. To correct this condition, additional
ballast water was pumped into the ship's cargo tanks to ensure adequate
vessel stability, to allow the ship to be safely re-floated.
Once the HMCS Protecteur left drydock, the existing block setting
was dismantled and then rebuilt to the required configuration for
the cruise vessel. This operation required a minimum of three days,
working twenty-four hours a day. The same block setting will also
be dismantled and rebuilt to suit the HMCS Protecteur for re-docking
after the cruise vessel has departed.
Consecutively, the F/T Saga Sea, a Russian registered fish factory
trawler, was undergoing extensive hull structural steel repairs,
in the forward section of the drydock. VSL personnel worked around
the clock to complete the work early, thus allowing the cruise vessel's
repair schedule to be maintained.
To add to the confusion another fish factory trawler, the American
registered F/T Arctic Storm was scheduled to enter the drydock on
June 11th, for an extensive refit scheduled to last approximately
three weeks. After numerous phone calls between various personnel
within the Washington Marine Group, it was determined our sister
company, Vancouver Drydock (VDC), could assist in the process. This
would require acceleration of their work schedule on the Crowley
barge 450-9. Therefore, the barge could be undocked earlier, which
in turn, would allow the Canadian Coast Guard vessel, C.C.G.S. John
Jacobsen to enter their dock ahead of schedule, for underwater hull
inspection, prior to departure for the East Coast of Canada
The F/T Arctic Storm left the VSL facility on the evening of Monday,
June 11th and set sail to Vancouver, for drydocking on the 700-ft.
long Panamax floating drydock at VDC, on Tuesday, June 12th.
It was at that point; VSL advised Celebrity Cruise Lines their
cruise vessel could be drydocked early on June 15th. In fact the
vessel arrived and stemmed the dock in Victoria at 0600 on June
14th, approximately 36 hours ahead of schedule much to the delight
of the owner.
Immediately the drydock was drained of water. VSL's work crews
went into action. Man-lifts were lowered into the dock bottom, along
with pre -packed work platforms, which contained the special tools
and equipment required to carry out the repair. Staging towers were
erected to access the propulsion unit. Lifting eyes were quickly
spotted and welded to the underside of the ship's hull to handle
the rigging required to remove the giant props allowing access to
the defective bearing. Shipyard crews assisted by some owner supplied
worldwide specialists worked around the clock to ensure the planned
time frames were met. Once the propellers were lifted free, the
end covers were removed to allow an examination. It was clear the
bearing was showing signs of wear.
The old bearing was removed and new bearings were fitted to the
unit. Upon completion, the entire system was flushed to remove all
foreign particles. When the system was clean the unit was energized
and trials were done to ensure correct operation prior to going
back into service. However, while the work was completed on the
starboard side propulsion motor the owner also decided to replace
the bearing on the port unit as a precautionary method. This was
deemed an appropriate time to do this exercise. Both units were
tested and given a clean bill of health.
The vessel departed VSL on Thursday, June 21st ahead of schedule.
The logistics required to accomplish all of the above could not
have been accomplished without the total agreement and close cooperation
of numerous players who include:
- Federal
Government Agencies: Canadian Immigration, Public Works Government
Services and Department of National Defense.
- Commercial
Ship Owners: American Seafood's Far East and Arctic Storm
Fishing Company.
- Washington
Marine Group: Victoria Shipyards and Vancouver Drydock Company.
- Manufacturers
Representatives: Alstom (France), Rolls Royce (Sweden), S.K.F.,
(Sweden) Chantiers (France) and D.S.S (Britain).
- And last
but not least, the Senior Port Engineers of Celebrity Cruise Lines
who had the confidence to award this technically challenging and
time sensitive contract to VSL.
"The above is a testament to the 'can do' attitude of the
Washington Marine Group and the several individuals from management
to shop floor personnel, who logically worked their way through
the maize of problems and came up with viable solutions," said
Malcolm Barker, VSL's Manager, Ship Repair. "Needless to say,
the G.T.S. Infinity was repaired and returned to service, ready
to undertake its next Alaska Cruise on June 22nd."
"Once again, the Washington Marine Group, specifically Victoria
Shipyards, has proven it is ready and capable of handling difficult
ship repair problems at a minutes notice," he said.
"This is an outstanding example of how a group of companies
and a number of government agencies were able to respond within
a very short time from a cruise ship requiring unexpected repairs,"
said John Hansen, President, North West Cruiseship Association.
"This quality of response is very important to the cruise industry.
The case is also a dramatic example of value added in BC as part
of the $500 million economic benefit of the industry in the region."
