Atlantic Tern sold

 Atlantic Towing Ltd has sold another of its laid up offshore support vessels. Atlantic Tern is the oldest and smallest vessel in the offshore fleet, but has found new owners reported to be in Croatia. They have renamed the tug/supplier Marjana K under the Panama flag.


Built in 1975 by Vito Steel Boat + Barge Construction Ltd in Delta, BC, the 1409 gt, 7040 bhp vessel has had a lengthy history of changes in ownership and name. All that does not require repeating since it has been posted here before: February 18, 2019


 Atlantic Towing Ltd based the tug in Halifax and it worked to support the last of the gas activity off Nova Scotia. As the offshore installations were removed, Atlantic Tern's presence, largely as a standby vessel, was no longer required and it sailed from Halifax for the last time August 18, 2020. It has been laid up in Stephenville, NL since August 20, 2020. The new owners have now reactivated the vessel and with its new name now shows up on some AIS sites.

No departure date nor destination has been posted yet.

Atlantic Oak(s) and Irving Oak [corrected]

 The oak tree is noted for its strength and durability, which may explain why it has been a favourite name for J.D.Irving / Atlantic Towing Ltd tugs.

The first to use the name was built in 1942 as Empire Spruce. Built by Richard Dunston Ltd, Thorne, UK, it was a Maple class steam tug, with a 500 ihp engine by McKie + Baxter. Intended for civilian service it was instead transferred for naval duties on the River Clyde. On January 9, 1943 it was in collision with a warship in tow at Gare Loch. Cut nearly in two it sank in 30 seconds carrying four crew to their deaths. However it was salved February 23 and taken to Glasgow where it was repaired and continued in RN service until 1945. It served briefly under civilian management with William Watkins Ltd in London, then with the Dover Harbour Board but in November 1945 returned to naval service. In March 1947 it was permanently allocated to the Admiralty and in August 1947 they renamed it Emulous.

I assume the tug was used in various naval dockyards, possibly doing some coastal towing. In 1958 it was stranded one mile east of Dover and was refloated by the Smit tug Brandenburg. Blankenburg*. With all the salvage capability of the RN it is strange that a Dutch tug would be used, unless it happened to be on the scene and responded to the emergency. I have no reports on the extent of damage, but it appears that the Admiralty did not think it was worth repairing because they sold the tug to H.G.Pounds Ltd, of Portsmouth on March 25, 1958. It is possible that Pounds made some repairs and even operated the tug, but better known as buyers, sellers and scrappers, Pounds may have kept the tug laid up.

J.D.Irving Ltd made a mass purchase of tugs from Pounds in 1961 which included several tugs and an LST to carry some of them to Saint John. On arrival the tug was rebuilt. Work included upgraded crew accommodation and installation of a war surplus 1440 bhp V-16 GM engine, built in 1945 for an LST. On completion the tug was renamed Irving Oak signifying that it would not be used for river work (which tugs had soft wood tree names) and was put to work in general towing and ship berthing in Saint John harbour.

 The tug carried on without attracting much attention until it was replaced by more modern units. After a period in layup it was taken out to sea off southwest Nova Scotia and scuttled in deep water August 30, 1991.

Next up for the Oak name was an oddity for J.D.Irving. Built for work in the Beaufort Sea by Allied Shipbuilding in North Vancouver in 1981 as Canmar Tugger a 3,050 bhp, 40 tonne bollard pull, ice class anchor handling tug, it was used almost exclusively for ocean towing. After Beaufort work shut down, the tug transferred to the east coast in 1991, via the Northwest Passage. On March 11, 1993 the tug began to take on water in Sydney, NS and the stern settled on the bottom. The wheelhouse was not submerged but the rest of the tug received considerable water damage. Atlantic Towing then bought the tug - probably for a very good price.

 


Atlantic Towing, in line with corporate policy renamed it Atlantic Oak.

In 2000 with newer tugs available, and ocean towing work much reduced, the tug was sold to Island Tug and Barge Ltd of Vancouver where it was renamed Island Tugger. It was initially put to work as an ITB tug, but has also been used in long range transpacific towing and into the arctic. 

In 2002 Atlantic Towing took delivery of hull number 78 from East Isle Shipyard  in Georgetown, PE. It was the fifteenth tug of a type built to a Robert Allen ASD design. The 4,000 bhp vessel was named Atlantic Oak. It was fully equipped with a towing winch and firefighting gear.




While some of the Georgetown tugs were built for their own account Atlantic Towing sold several of the tugs to overseas buyers after some limited use by ATL. In 2003 the second Atlantic Oak was sold to Dominican Republic owners Remolcadores Dominicanos and renamed Ocoa. It is still in service.

ATL eventually completed a joint venture with Svitzer wherein ATL took over tug operations in Halifax Harbour. Due to the size of ships coming to the port tethered escort tugs had become mandatory and ATL had the next tug built specifically for that service in Halifax. East Isle Hull No.81, the 18th tug in the series at 5,050 bhp and 66 tonnes bollard pull became the third Atlantic Oak. That tug is still in service in Halifax and shares tethered escort and general docking duties with three other tugs.



As you can imagine I have many photos of Atlantic Oak (iii), including the title photo for this blog. Here is a selection:

Atlantic Willow - correction and clarification

A regular Halifax based tug for several years is the Atlantic Willow. One of the large series of ASD tugs built by Irving Shipbuilding's Eastisle Shipyard , it was based on the original Robert Allen Ltd design, but with some modifications. It entered service in 1998.

Atlantic Willow moves between assignments in Halifax harbour.
It is still using the winter shelter over its ship handling winch on the foredeck.

It was the first tug in the series to be built with the full firefighting package, because it was intended for use at the NuStar oil terminal at Point Tupper, on the Strait of Canso. Presumably that is why it is the only tug in the ATL fleet registered in Port Hawksbury, NS instead of the company's home port of Saint John, NB. It was also equipped with a towing winch aft. 

The tug is rated at 4,000 bhp / 50 tonne bollard pull - somewhat less than the 5,000 bhp / 66 tonne, 5,500 bhp / 70 tonne ratings of the other Halifax tugs. Nevertheless it is still a hard working member of the fleet and it is often designated to work at the bow of a ship and with the smaller ships. 

In case the above photo is a bit placid looking, it should go on record that the tug can "step out". 

Irving tugs have traditionally been named after trees, because the company got is start in the tug business by towing timber on the Saint John River. Originally the river tugs were named for coniferous (softwood) trees (used for lumber and paper making), whereas coastal and ocean tugs were named for deciduous (hardwood) trees. No distinction is made now since some harbour tugs work coastal, and there is no longer any river work.

However, due to the limited number of local tree species, the names do get re-used. Such is the case of the willow, a name used in the fleet from 1980 to 1996. Irving Willow was built in 1958 by J.I.Thornycroft in Woolston, UK for Red Funnel Tugs of Southampton, UK as Dunnose. It was one of a series of first generation twin screw diesel tugs, built to serve the large ships, including the "supertankers"  of the 1950s. Its two 6 cylinder Crossley's giving 1340 bhp became obsolete for that purpose as ships continued to grow, and it was replaced with a new generation. Irving acquired four tugs from the Red Funnel fleet, three of which went into regular service.

Irving Willow ex Dunnose was assigned to the Harbour Development Ltd division of Atlantic Towing Ltd and tended barges and dredges all around the Atlantic region. In 1995 Atlantic Towing Ltd and Harbour Development Ltd,  were given a separate corporate identity under the J.D.Irving branch of the family companies, as distinct from Irving Oil. Most Irving tugs were given the "Atlantic" prefix, however those attached to Harbour Development  Ltd were given a "master" suffix, and Irving Willow was renamed Wavemaster in 1996. It carried that name until it was broken up in Dartmouth, NS in 1995.

CORRECTION: The Atlantic Willow does not carry a towing winch. The most photo I have that shows the tug from the stern, has a picnic table where a towing winch could be installed if needed.


CLARIFICATION: In addition to Atlantic Willow, 4,000 bhp, Atlantic Towing Ltd normally posts two 5,000 bhp tugs and one 5,500 bhp tug in Halifax. The one larger tug is drawn from the three tugs built for working with LNG tankers at the Canaport buoy off Saint John, NB. If needed for an LNG tanker it will return to Saint John, but this is now a rare event. Currently that tug is Atlantic Beaver. The two 5,000 bhp tugs based in Halifax are Atlantic Oak and Atlantic Fir.

Thanks to readers for pointed out the error and inaccuracy in the last post.
