Troms Sirius returning to Halifax for the last time, Christmas Eve.
A 4,201 gt vessel with a deadweight tonnage of 4868, it was built to the VARD PSV 09L CD class, and is fitted with numerous tanks for carrying fluids and a large cargo deck. It is also equipped with firefighting gear and DP 2, and numerous other features. Powered by four Caterpillar diesels, driving four electrical generators, it delivers 11,200 bhp to twin screws. It is also equipped with an azimuthing bow thruster and two tunnel thrusters.
It was registered in Halifax March 9, 2018 after a brief period operating under a coasting license. Followed shortly after by the similar ship Lundstrom Tide and Horizon's own Horizon Star it supported the ultra deep water semi-submersible drill rig West Aquarius. The rig was mobilized in Newfoundland and in April began to drill an exploration well, Aspy D-11, 330 km southeast of Halifax. By November the well had found no commercially viable oil or gas and demobilization began. Troms Sirius escorted the rig back to Bay Bulls, NL then returned to Halifax.

There are no exploration or development projects planned off Nova Scotia. The only work in the area is the decommissioning of the two gas fields that have both ceased production.
Troms Sirius refueled at Irving Oil on Tuesday January 8, then tied up at the Cove with Lundstrom Tide and Horizon Enabler (ex Tidewater Enabler). Both those vessels are also idle.
PlusOn Saturday January 12, Lundstrom Tide also left Halifax. Its destination however is Limassol, Cypress. Sailing under the Vanuatu flag, it is giving an ETA of February 2.
