Final Voyage of CCGS Hudson

Commissioned in 1964 as Canadian Survey Ship (CSS) Hudson, she was the first dedicated hydrographic and oceanographic vessel built for Canada and served the Canadian Oceanographic Service until 1996 when she was transferred to the Canadian Coast Guard fleet to become CCGS Hudson. I have photographed this ship many times over the last 25 or so years.

Despite a recent refit that was intended to extend the ship's life until replacements could come online later in this decade, one of the ship's two electric motors that drive the ship suffered a catastrophic failure and has been deemed not worth repairing. The ship will therefore be retired and returned from St. John's, NL, to Halifax on her one remaining motor on what was her final voyage under her own power.

I managed to catch her return from the Macdonald Bridge this past Monday, January 24. She was escorted for at least a portion of her voyage by CCGS Sir William Alexander, who preceded Hudson and saluted the latter using her firefighting monitors, and the lifeboat Sambro and an inflatable also escorted her into the harbour.

With Hudson now gone, the Canadian Coast Guard will have a large gap in their research fleet until her replacement comes online.

CSS Acadia returns from refit in Shelburne

The retired Canadian Hydrographic Vessel CSS Acadia, also ex-HMCS ACADIA in two World Wars, returned to the Maritime Museum of the Atlantic today after a refit and inspection in Shelburne. She left Halifax in August. 

Acadia was towed from Shelburne to Halifax by the tug Atlantic Elm, and was then handed off to the harbour tug Atlantic Fir.
Atlantic Fir was rafted alongside Acadia and brought her up the harbour backwards.

Acadia looked very sharp with her new paint job.

Atlantic Elm escorted the two ships up the harbour after handing over the tow to Atlantic Fir.

Launching the future HMCS MAX BERNAYS

As hinted in my last post, the future HMCS MAX BERNAYS was rolled onto Boa Barge 37 on Friday in advance of her launch on Saturday. (For brevity, I will just refer to her as MAX BERNAYS from now on.)

As noted in my previous post, the red wheeled transporters in the foreground are positioned under the ship's cradles, and the entire assembly of ship and cradles is rolled out onto the Boa Barge 37.

I will start with a photo from a week or so ago, showing the ship up on the land level transfer area, prior to the transfer. She was located under the tower crane and next to the elevator tower.

MAX BERNAYS up "on the hard" prior to the transfer.

On Friday, the transfer began and the ship was moved backwards onto the barge. I nipped down over my lunch hour to grab a few photos.

MAX BERNAYS moving back onto the barge. Boa Barge 37 is the red barge with the white superstructure in this photo.

It has been noted on Twitter, where I first posted these photos, that MAX BERNAYS is the first of the AOPVs to be painted with a blue antifouling paint. The previous ships were painted with a red bottom, with a suggestion (not verified by me) that the red paint was the same as that used by the Canadian Coast Guard on their icebreakers. No word yet on whether this blue paint is a new product that will also be good in ice, or if it has been decided that the ship doesn't need the red paint.

When I returned later in the afternoon, the ship was entirely on the barge. 

If you look closely, you can see the red transporters under the cradles.

On Saturday morning, the Boa Barge 37 and MAX BERNAYS were towed out into Bedford Basin. The semi-submersible Boa Barge 37 was sunk underneath MAX, and the latter floated off around 4pm. I missed the actual launch, but managed to catch MAX's return to the shipyard in the early evening.

MAX was towed as a dead ship from the launch location back to the shipyard, under the command of two tugs.

The ship was turned before going alongside at the shipyard.

The ship is by no means finished, and work will continue for a number of months to complete the ship's interior and to commission it various equipment and systems. Various pieces of equipment also still need to be installed, such as sensors and the main gun. The ship is scheduled to be handed over to the Navy sometime in 2022, and won't likely commission until 2023 at the earliest after the Navy's own process of handover and familiarization.

Future HMCS Max Bernays

The future HMCS MAX BERNAYS, the RCN's next-to-launch Arctic and Offshore Patrol Vessel (AOPV), continues to take shape at the Halifax Shipyard - with some speculation that she may be ready to launch in the near future. Personally, it looks to me that there is some final painting of the hull that should be done prior to launch, but in any case I thought it would be a good opportunity to take some photos of the ship out of the water.

Interestingly, the antifouling paint on the MAX BERNAYS is the traditional blue that we tend to sea on the HALIFAX-class frigates, whereas, I believe the two previous ships (HARRY DEWOLF and MARGARET BROOKE) were both launched with red antifouling. 

The red wheeled platforms in the foreground are the transporters that will lift the cradles upon which the ship is supported, and will move the ship onto the semi-submersible launching barge (Boa Barge 37) when the time comes. The barge's white superstructure can be seen in the background, behind the ship's stern.

This view shows well the icebreaking profile of the ship's bow.

Updated: According to Halifax Shipping News, MAX BERNAYS will be rolled onto Boa Barge 37 on Friday October 22 in order to be launched on Saturday, October 23, 2021.

HMCS HARRY DEWOLF alongside in November 2020.

Back in January, I was fortunate enough to receive a tour of the future* HMCS HARRY DEWOLF and to interview her Commanding Officer, Cdr Corey Gleason, to support a two-piece article in the April and May editions of Warships IFR magazine. Now that both pieces have been published, I can provide a short tour of the ship.

*HARRY DEWOLF is scheduled to commission this summer, and as such, would normally not be referred to as "Her Majesty's Canadian Ship" until that happens. However, the Navy has decided to simplify things in the interim and simply refer to her as HMCS HARRY DEWOLF, and so I shall do so from here on, or will simply refer to her as HARRY DEWOLF.

HARRY DEWOLF alongside in late-December, during the departure ceremony for HMCS HALIFAX for a NATO tour.

HARRY DEWOLF is the lead ship in a class of 6 Arctic and Offshore Patrol Vessels (AOPV) being built for the Navy, plus two more ships that will be adapted for the Canadian Coast Guard. These multi-mission ships are primary intended to fill the patrol mission and free up the Navy's surface combatants for higher intensity roles, but they are also designed to be as modular and flexible as possible, to allow them to fill many other roles as well.

Although a cold day, the day of my tour was sunny so at least my photos are fairly well lit. One notable feature of the ship, and indeed a feature not found on any other class of RCN vessel, is the enclosed forecastle (or foc'st'le). This allows the crew to handle the bow lines from an enclosed space while operating in inclement conditions - the four square-ish ports above the three fairleads can be opened to allow the crew some visibility outside, but heaters inside will keep them warm.

Another view from within the enclosed foc'st'le, but this time from floor level.

The fairlead in the centre of the image is on the bow centreline, and some of the square ports can be seen on either side of the space. Several of the heaters can also be seen, along with a number of winches and the cable handling gear for the two anchors.

At the rear of the ship on the quarterdeck, behind and below the flight deck, there is another feature not normally seen onboard an RCN warship - there is a 20-tonne crane on the port side, along with a smaller 3-tonne crane on the starboard side. The former is necessary to handle not only the various containerized equipment or cargo that HARRY DEWOLF can carry, but also to handle the ship's landing craft.

HARRY DEWOLF's landing craft.

In addition to the landing craft on the quarterdeck, the ship has dedicated recessed bays for four small boats including two fully-enclosed lifeboats (the orange object in the rear bay seen in the alongside views of the ship above) plus two Rigid-Hulled Inflatable Boats (RHIBs) in the two forward bays (also visible in the alongside photos above). 

To support the deployment of small boats from these ships, the staging compartment beside the RHIB bays are even fitted with drying racks for wet suits (though presumably they could also be used for foul weather gear).

Under the landing craft's bow ramp is a small V-shaped bow.

Just ahead of the landing craft is a small hangar for the types of wheeled vehicles that HARRY DEWOLF will need to deploy shore while working in the Arctic.

Looking forward at the small vehicle hangar, located underneath the ship's helicopter landing deck.

The quarterdeck has dedicated stowage locations for containers - both storage containers as well as containerized mission packages, such as the containerized towed array that was onboard for tests when I toured the ship. In future, containers could be embarked to provide the Canadian Hydrographic Service with survey equipment, or to support numerous other missions.

Two decks up is the ship's flight deck and helicopter hangar. Designed to operate the CH-148 Cyclone helicopter, the ship is fitted for (but not with) the "Beartrap" or RAST helicopter-hauldown  and traverse system - this is the system fitted (in various iterations) to the RCN's helicopter-capable frigates and destroyers since the 1960s to allow the ships to operate helicopters in a wide range of weather conditions and sea states. From my discussion with Cdr Gleason, I assume that the Navy will see how these ships handle at sea before deciding whether to fit this system - after all, these ships are slightly larger than the Halifax-class frigates, and may be more stable at sea if handled properly.

On either side of the flight deck's forward end are two refueling stations for underway replenishment - the jackstays are not permanently installed, and must be erected and struck down each time they are used.

Flight deck and hangar. The Beartrap track can be seen running along the deck and into the hangar, and the port lifeboat can be seen here. Flying Control (FlyCo)  can be seen directly above the hangar.

The ship is fitted with a larger, roomy, and modern bridge.

The bridge looking to port.

The ship doesn't have overhanging bridge wings - as nice as they would have been - and I seem to recall a comment to the effect that they would have made the ship too wide to fit into seaway locks. Immediately aft of the bridge is the Multi-Purpose Operations Space, or MPOS. In addition to filling the requirement for an Ops room from which the ship's military missions can be commanded, the MPOS can be tasked to support numerous purposes - for instance, an embarked team of hydrographers from the Canadian Hydrographic Service could control a hydrographic survey, or a non-government organization could be embarked to coordinate a relief mission ashore after a natural disaster. The bridge is large and flexible enough that the Navy crew can dedicate the MPOS to such an embarked team while using the bridge as a temporary Ops room. 

The bridge overlooks the 25mm gun.

While the size of the ship's gun seems to have many detractors, Cdr Gleason praises its tracking and targeting abilities, and points out that it is well suited to the HARRY DEWOLF's constabulary role. IT is important to remember that these ships are designed and built to civilian standards, and are not built as true warships. The stowed davit can be erected over the hatch to the right of the gun, and is used to bring up ammunition to the gun.

The interior of the ships is not what the Navy's previous generations of sailors would have been used to - the level of habitability in these ships is a large improvement over past classes of ships. The accommodations as well are much improved.

The ship's aft engine room.

The ship's diesel-electric powerplant is equipped with four diesel generators in two engine rooms that in turn generate power to run the two electric motors that power the ship's fixed propellers. Apart from submarines, the Navy's ships are not diesel-electric - for instance, in the Halifax-class frigates, power goes directly from either the propulsion diesel or the two gas turbines to the variable pitch propellers via a gearbox. These ships were provided with a diesel electric power plant as it is preferred for ice breaking.

I will finish off with some more exterior views of the ship.

For more information on these ships and for my interview with Cdr Gleason, please check out the April and May issues of Warships IFR magazine. For obvious reasons, I have not reproduced most of the interview content here.
