Ocean Ranger Anniversary

Today Marks the 35th anniversary of the loss of the drilling rig Ocean Ranger and all 84 persons on board. The world's largest semi submersible was working on the Hibernia field 166 miles east of St.John's when it was struck by a severe storm.

The rig was supposed to withstand harsh conditions but a sea broke through a portlight washing out the ballast control room. Unable to prevent further flooding, the crew attempted to abandon the rig in appalling conditions, but did not survive.

A Royal Commission found numerous faults in the design of the rig, inspection, training and safety procedures.

At the time of the loss there were two other drill rigs nearby, Sedco 704 and Zapata Ugland. Both suffered damage, but survived.

All three had standby boats in the area, but there was little they could do but assist in recovering bodies.

The standby boat for Zapata Ugland was Nordertor. Built in 1976 by Hitzler, Lauenburg, it was owned by Offshore Supply Association.

 Nordertor was often seen in Halifax, working for Esso.

A sister vessel Boltentor was standby for Sedco 704.

Seaforth Highlander was standby boat for Ocean Ranger.
It was built in 1976 by Ferguson Brothers, Port Glasgow, Scotland and was operating for the Seaforth Fednav joint venture.

A sister tug/supplier Seaforth Jarl from the same builders in 1975 was lost December 18, 1983 when an improperly secured deck load of chain ran overboard and capsized the vessel. The crew was rescued by Arctic Shiko.

Sixty-five miles to the east the Russian Mekhanik Tarasov was struck by the same storm. On a trip from Trois-Rivières, QC to Leneingrad, it attempted to assist in the Ocean Ranger rescue operation, but took a severe list eventually capsizing February 16 with the loss of 32 of its 37 crew.

The crew of the Atlantic Project were more fortunate. All survived a fire aboard their vessel between Newfoundland and Nova Scotia February 14, 1982. The ship reached Halifax safely February 15, thus escaping the worst of the storm.

Bugsier Tugs in Halifax

The 1960s to 1980s were the boom years for deep sea salvage and towing tugs. The writing was on the wall however, for offshore anchor handling tugs were poaching the once exclusive territory of the big Dutch and German companies. Although not ideal for towing, the offshore tugs were powerful and did not depend on long tows and the occasional salvage job to pay the bills.

Dutch and German companies ruled the waves, although many other countries had big tugs too. Prime among the German companies was Bugsier of Hamburg. As they rebuilt their fleet post World War II, they continued to build larger and larger and more capable tugs, primarily for salvage. At the same time the oil industry was building larger and larger drilling rigs, and so the tugs were employed to tow the rigs over long distances to various oil fields.

From the 1960s Bugsier expanded its fleet dramatically, with ever larger tugs, several of which visited Halifax.

Here is a selection:

Albatros built 1965 visited Halifax on a salvage job.

Tied up at Purdy's wharf , Albatros had arrived towing Reefer Trader from 900 miles out at sea. The ship was on a trip from New York to Tenerife with frozen chickens when it broke down. Delivered to Halifax it was soon repaired and on its way again.

 A Benny Claus photo from my collection shows the tug arriving in Antwerp.

Simson built 1973, was one of  three  sister tugs with Titan and Wotan .

Simson was in port briefly in January 1975. Even in winter the crew was doing some work overside while at Purdy's wharf. It did not tow anything in our out, so may have been on salvage spec.
Simson tied up at the Long Wharf, Dartmouth Marine Slip, after towing in the jack up oil rig Rowan Juneau. It is standing by to tow the rig to Sable Island.

Jacques Carney took this photo of Wotan, likely in Brest, France.
It visited Halifax in 1974 and with Irving Maimi towed the drilling rig Sedco 704 to the North Sea.

Oceanic was the largest tug in the world. Built in 1969 it was almost brand new on its first arrival in Halifax.

 Oceanic was back in 1981, having been re-engined for more power. 
Nevertheless every available tug assisted it into port with its tow.
Oceanic arrived with the drilling rig Bredford Dolphin from Gibraltar. 
The supplier Seaforth Jarl  also assisted the tow in.

Oceanic was back in 1982 towing the rig John Shaw from Japan.
Point Vigour stands by as Point Vibert and Seaforth Jarl take up trailing lines.

Oceanic spent a few days at Purdy's Wharf on completion of the tow.

Power measurements are difficult to pin down, but the tug's bollard pull was more than 150 tonnes, and possibly 170 tonnes with the new engines. It had an enormous range and could reach 20.5 knots.

The bottom fell out of the salvage and towing business in the mid-1980s and Bugsier retrenched to their home base in Germany. They now concentrate on harbour towage, coastal and near offshore towing.

Although more powerful tugs are now available, they are generally built along supplier lines and are not nearly as attractive as these traditional boats.

Svitzer Bedford has a tow

The Point Tupper based tug Sitzer Bedford has the disabled cargo ship Thorco Crown in tow and should be arriving in Sydney this evening, just in time to avoid the latest incoming storm.
After discharging a cargo of drill pipe in Argentia, NL, the ship was headed for Montreal when fire broke out in the engine room February 6. Although the crew was able to put out the fire, the ship was left drifting 32 nautical miles from Port aux Basques. CCGS Sir William Alexander stood by and made up a tow line to kept the ship from drifting toward shore during the night.

The ship's owners hired Svitzer Salvage to fetch the ship. When Svitzer Bedford arrived on scene it was too rough to take over the tow immediately, but the line was passed on Thursday and the tow began. Initial reports that the ship would be towed to Port aux Basques were soon revised. Sydney is the only appropriate destination, since no facilities exist in the former port to effect repairs.

Svitzer Bedford is one of three Svitzer Canada Ltd terminal tugs based in Point Tupper, and is the designated escort tug. A 4895 bhp ASD tug with controllable pitch props and bow thruster, it has a published bollard pull of 56 tonnes. It is also fitted with a towing winch and although rarely used for outside work, it is more than capable of seagoing. It was built by ARSENAV in Chile in 2005 and initially served Halifax harbour before Svitzer transferred its tugs to the Strait of Canso in 2012.

Much has been said in these pages about rescue and emergency towing tugs. The government has also come under criticism for not mandating or equipping the Canadian Coast Guard for emergency towing.
This particular case shows that the Coast Guard can at least help to stabilize a ship until a proper towing vessel can arrive on scene, and that is as it should be.

It must be added however that the Thorco Crown at 7767 grt is a relatively small ship and in truly adverse conditions or in ice even as capable a tug as Svitzer Bedford would be hard put to render assistance to a larger ship. The recent grounding of Arca 1 in the same area was handled well by McKeil Marine but only after the ship was aground. There was no assistance available to the ship during the several hours before the grounding, even though it was also very small.

There should be a large ice class tug on standby in the Sydney area, particularly at this time of year, to respond to emergencies.

Feast or Famine in the Offshore and more on Bollard Pull

After an active year or two for offshore supply vessels, Halifax has now entered another drought, which shows little sign of improvement in the near term. As with the rest of the world, oil exploration and development has hit the skids and huge numbers of support vessels and drill rigs have been stacked. Halifax was a bit of an anomaly due to Shell's exploration drilling off Nova Scotia using the drill ship Stena ICEMAX.

However that troubled program turned up disappointing results on top of all the difficulties and the drill ship has moved on to its next assignment. (It is currently anchored in Las Palmas). The three suppliers used to support it are all now idled in Halifax.

Skandi Flora and Maersk Nexus are tied up at the IEL and Mobil docks in Dartmouth, and Scotian Sea at the old Coast Guard  base (see Shipfax January 30). The standby boat Atlantic Tern is idled at pier 9C also. There are no prospects in the offing unless Shell is forced to pick up the abandoned drill stem it dropped on the ocean floor a year ago.

BP also has plans for an exploration program in 2017, but details are scarce. In view of the world situation for this type of vessel, they may be laid up for some time.

Meanwhile both offshore gas facilities are experiencing problems.  Encana's Deep Panuke is winding down  to seasonal operation due to low process and water issues, but the supplier Atlantic Condor and standby Atlantic Tern remain employed..

The other Sable Island area gas project,  the Sable Offshore Energy Project (SOEP) (Exxon Mobil are the lead operators) has Venture Sea and Siem Hanne contracted. The project began production in 2013 but is not expected to last out its projected 13 year lifespan. The supplier Trinity Sea has been laid up in Dartmouth for several months.

Meanwhile at Halifax Shipyard the two newbuilding suppliers Atlantic Griffon and Atlantic Shrike have completed their first sea trials and bollard pull*tests. They continue fitting out at pier 9B, still in the hands of Damen, their builders. No date has been announced for handover to Atlantic Towing Ltd, but I am told that the third of the four tug order is en route to Damen's home shipyard in the Netherlands for its final trials.

There have been slow downs like this in the past as the oil industry is notorious for hills and valleys, but the current depressed market has seen numerous business failures and restructurings and still shows only faint glimmers of any sort of recovery.

Just astern of the new suppliers in the photo above, the cable ship Isaac Newton is in layup. Its operators, Dredging and Maritime Management SA (DMM SA) have applied for another coasting license for 2017. Apparently the ship did not complete its work on the New Brunswick / Prince Edward Island power cable project before the onset of winter. It is expected to resume work March 15 and complete by June 15.

* Bollard Pull
For many years bollard pull trials were conducted in Halifax off  the end of Pier 22 where there is a large, deeply rooted bollard, known as the "Queen Mary Bollard". There is one of these huge concrete filled steel bollards at each end of the seawall, at Pier 20 and Pier 22. They were installed when the seawall was built to accommodate the largest ships of the time, which was pre- Queen Mary, but that name has been used for many years. I probably have some more recent or clearer photos of the bollards,  but due to present day security restrictions I can't get near enough to take any pictures now.

The Pier 20 bollard at the north end of the seawall looked like this in 1970:

The bunkering tanker Imperial Cornwall is delivering some Bunker C fuel to the Nova Scotia Light + Power generating station (now the Nova Scotia Power Corp head office) and the Pier 20 Queen Mary Bollard sit in the foreground. It is large, deeply set in and surrounded by a working area.  

The water is deeper and there is lots of sea room off the end of Pier 23.

The south Queen Mary bollard is directly above the wheelhouse of the Canada Pilot No.4 as it speeds into port. The Italian passenger liner Leonardo DaVinci is making its approach to pier 21- mid-berth on the seawall.  A Russian trawler occupies the south end of pier 22 and another ship is tied up at pier 20 in the background.

Numerous Georgetown-built tugs conducted their bollard pull trials off pier 22.

Océan Raymond Lemay is set off diagonally from the corner of Pier 22 to prevent prop backwash from effecting the trial results. A fender is being swept away from the pier by the wash.  

Pier 22 is not accessible to vehicles, so it is more convenient to conduct trials off the end of pier 26. There is an equally large mushroom head bollard there, which would prevent the line from slipping off. I probably have a photo of it somewhere, but it is no longer accessible to unauthorized persons such as I.

Seven Seas Mariner glides in past the end of Pier 26. The yellow bollard is set back from the corner of the pier providing room for the load cell measuring device. (There is also a yellow railway bumper partially blocking the view.)
Here is a blow up:

  Yellow rail bumper, mushtoom bollard, light pole and fire hydrant occupy the end of the pier.
