Horizon Arctic

Another Large offshore vessel, the Horizon Arctic arrived at pier 9. i have been told the vessel will be setting the anchors that will hold the Boa barge 34 when it arrives in Mulgrave.

the Horizon Arctic is the largest of three ships operated by Horizon Maritime. it was built by Vard in 2016, and operated as the Bourbon Arctic until Horizon acquired it in March of 2019.

the ship features a 308ton bollard pull, and her towing winches are rated to 500 tons.

Maersk Cutter.

Maersk Cutter, another relatively new new Offshore vessel put into Halifax. it is expected to sail overnight.

Built in 2015, and Flagged in Canada, the ship normally works in the Newfoundland offshore. The Thalif may be taking a break from Sable decommissioning work to install 2 cranes on the Hiberina platform, so this visit may be related to that.

Wilson Mistral with Anchors.

the general cargo ship Wilson Mistral arrived just after midnight, and tied up at pier 9. Loaded with anchors and Chains, these will be installed in Mulgrave by the Horizon Arctic (due in Halifax July 6) to hold the Boa Barge in place with the Deep Panuke Production platform aboard.

the ship arrived from Montrose, Scotland, and is very small.

the ship is due to move to pier 27, likely for fuel, at 10pm tonight.

Boa Barge 34 and Deep Panuke Platform

the tug Boa Odin delivered the Boa Barge 34 to Pier 9. The Barge will be used too remove the production platform for the Deep Panuke offshore gas project. The Platform features jack up legs. Once the platform is positioned underneath the platform, the platform will lower itself onto the barge, and then withdraw its legs from the Seabed.

Nobel Regina Allen is Currently plugging the last well of the project.

Since the platform is still relativity new, a costing trade application was filed to allow the platform to be stored aboard the barge, at anchor in Mulgrave for 1 year.

Boa Barge 36 was used for the installation of the platform in 2011.

Fall Pipe Vessel Adhemar De Saint-Venant

Jan de Null operates the 2017 built Adhemar De Saint-Venant. The ship is designed to lay rock on the ocean floor.

The vessels will be able to install rock at depths up to about 600 m by means of a flexible fall pipe to allow for accurate rock installation around structures such as offshore wind turbine foundations and Oil & Gas platforms. The ships Spec Sheet (PDF) give a good view of the vessel

the ship sailed from Saint John, and was spotted off the Coast of Virginia, likely building the bases for the Offshore wind farm which was installed by Vole au vent out of Halifax.

The ship is named after Adhémar Jean Claude Barré de Saint-Venant who developed the unsteady open channel flow shallow water equations, known as the Saint-Venant equations, that are a fundamental set of equations used in modern hydraulic engineering

Update:
Sailed at 1400 under fog.

Vole Au Vent

the offshore wind installation vessel Vole au Vent arrived this morning, and tied up at Irving oil for bunkers. the ship will then move to Woodside this afternoon to load the base pieces for installation.

The pieces arrived several weeks ago aboard the Bigroll Beaufort. the installation is taking place off the Coast of Virginia, and is staging out of Halifax to work around US cabotage laws. Vole au Vent will make several trips, to install the Bases, Towers and turbines.

UPDATE May 18:
the ship is now jacked up and in position. Im told the Installation will happen in three trips, first the bases, then the Towers, then finally the top assemblies.

UPDATE May 19:
Looks like the first pieces have been loaded.

Suppliers at Pier 9.

The Photo doesnt do it Justice, but Atlantic Osprey is completely dwarfed by the new Maersk Suppliers, both of which are here as part of the Sable offshore decommissioning. Maersk Maker has been in Halifax for a while, and was joined by Maersk Mobiliser. Mobiliser has been to Halifax before, as one of its first jobs was the the tow of the fire damaged Yantain express.

Bigroll Beaufort.

Arriving late this afternoon is the the Bigroll Beaufort, loaded with 2 offshore wind turbines for the CVOR, or Coastal Virginia Offshore Wind Project. The ship will be tieing up at Woodside.

To get around the US Jones act, the Turbine equipment will be delivered to Halifax, where it will be loaded on the Installation vessel Vole au Vent, to then be taken to the installation site off the Virginia Coast. Vole au Vent is still in Rotterdam.

The Jones act is a piece of US legislation that requires any transport of goods between US ports to be done on US Built, Crewed and Flagged ships. Currently there are no US Offshore Wind installation vessels.

From the Project Release:
“Dominion Energy and Ørsted announced today the turbine components and monopiles for the Coastal Virginia Offshore Wind (CVOW) pilot project have started their journey to North America.

The foundations, consisting of the turbines’ monopiles, transition pieces and anode cages fabricated by EEW SPC, have been loaded onto the Bigroll Beaufort cargo ship in Rostock, Germany. The components for the two, 6-megawatt Siemens Gamesa turbines were loaded in Esbjerg, Denmark, before the vessel embarked in mid-April on the approximately two-week transatlantic journey to Halifax, Nova Scotia, Canada

Installation of the two turbines, located 27 miles offshore, is expected to begin later this spring and they are expected to enter service by the end of the year.”

Markab

Markab on Feb 8.

Markab returned to pier 9 this morning. it was last here Feb 8., before sailing to Bridgetown Barbados. Built in Norway in 1976, the ship now is operated by Furgo, and was likely conducting a subsea survey.
