Trinity Sea - on trials RE-UPDATED

After an idle week or two at the old Coast Guard base in Dartmouth the tug supplier Trinity Sea got underway again this morning and to the deepwater piers for trials, which appear to have included bollard pulls or DPs based on the AIS track over several hours.

Trinity Sea with Atlantic Towing's Atlantic Condor in the background, heading for trials off pier 28.

One of three similar boats in the current Secunda (Siem) fleet, it was built in Szczecin, Poland in 1983 as Neftegaz 2. Secunda purchased it and sister Neftegaz 1 from layup in Norway and they arrived together in tow of Magdelan Sea on May 18, 1998.

Magdelan Sea tows up the harbour with Point Chebucto assisting. 

In the left background the tug Plainsville; it landed deck hands to assist in pairing up the tows.

Neftegaz 2 was gutted down to almost the bare hull and totally rebuilt in Halifax as a DNV class 1A1 ICE-1C tug / supplier with FF1 firefighting equipment and renamed Trinity Sea.

After removing most of the superstructure, the Trinity Sea's hull was hauled out at the Dartmouth Slip for rebuilding.

Totally transformed as a virtual new ship, Trinity Sea.

The aft facing bridge is the most prominent addition to the ship's profile.

Based from time to time in Halifax and overseas, Trinity Sea has mostly worked in Newfoundland so has been only an infrequent caller here over the years.

Point Chebucto shepherds the pair toward pier 9.

Sister vessel Neftegaz 1 was also completely rebuilt to the same standard, with much of the work accomplished at Verreault Shipyard in Méchins, QC.

Hastily renamed Burin Sea the former Neftegaz 1 sits at the IEL dock in Woodside in preparation for gutting out.

Point Halifax readies the stripped out hull to be towed to Verreault by Point Carroll.

The rebuilt vessel was towed back to Halifax by the Point Carroll and fitted out.

I understand that the appeal of the two hulls was their high quality Polish steel, heavy ice class and reliable Sulzer engines (built under license). They are now rated at 10,000 bhp on their two main engines and equipped with one 600 bhp and one 900 bhp bow and one 900 bhp stern thruster.

Secunda's Panuke Sea ex Neftegaz 14 will be the subject of another post at another time.

Update: Shortly after this post was initially published, the tug Trinity Sea appeared on the shipbroker Offshore Solutions Unlimited 's website. Several of the particulars listed above are now different, including a bollard pull of 80 tonnes, and engines of 3,600 bhp each. There is also additional information including the vessel is DP1, that it has accommodation for 28 persons and has standby / rescue capability.
THE UPDATE WAS AN ERROR.
New Update: The shipbroker Offshore Solutions Unlimited is offering fleetmate Panuke Sea ex Neftegaz 14 for sale - see subsequent post.
