Boa and Boa

The tug Boa Odin arrived this morning towing the Boa Barge 33. The big Norwegian tug towed the barge from Stavanger in 22 days, averaging 6.2 knots.

The tug was built by Astilleros Zamakona Pasaia in 2010 as Svitzer Pembroke. A Robert Allen RAStar 3600 design, it is powered by two GM engines of 4083 bhp driving Schottel ASDs. It is rated at a surprising 97 tonnes bollard pull on its forward winch and 105 t BP on its towing winch. Fitted for salvage, towing and offshore work, it also has firefigthing and escort capabilities. Boa Tugs acquired the tug in 2014.

Its tow, the 12,303 grt barge is semi-submersible for heavy lifts with a carrying capacity of 24,800 tonnes.It was built in 2011 by Nanjing Wujiazui Shipbuilding Co Ltd. The 140m x 36m barge can submerge 8m below deck forward and 12m above deck aft and its 4,690 m3 deck can support 31.5 tonnes/m2.

The barge will load the two sections of the panamax floating drydock Novadock. It was renamed  F.D. Novadock under foreign flag, before it was cut in two. The severed sections have now been plated in and will be used as two floating drydocks by new owners in Florida.

A Brace of Suppliers

After last year's major seismic exploration venture in the Shelburne Basin off Nova Scotia, Shell Oil received enough favourable information to begin drilling with the drill ship Stena Icemax..

Canadian supply boat operators had no available/suitable vessels to support the operation and have resorted to chartering in foreign tonnage for the work.

Atlantic Towing Ltd has received Canadian Transport Agency OK to bring in two suppliers on bareboat charter from Tidewater for a year less a day.

Sisters Jones Tide and Breaux Tide arrived in Halifax when I was away in August and their registration was changed from Port Vila, Vanuatu to Halifax, effective August 31.
The suppliers were built by Jiangsu Zhenjiang and measure 3,927 grt and 4,578 dwt.

DOF Rederi AS of Storebo, Norway, through their Canadian subsidiary DOF Subsea Canada Corp have brought in Skandi Flora, which was built in 2009 by STX Norway Offshore in Trondheim. It measures 4469 grt, 5005 dwt.


It was registered in Halifax September 3. So far it is the only one of the boats that has moved, but only to shift piers. 

They are all still awaiting arrival of the Stena Icemax, which was to start work roughly September 1, but is still reported to be in the Gulf of Mexico.

Oh and the Quiz answer from my last post. That is my friend in front of a giant winch reel in a shipyard in Singapore.
