| CCGS Naalak Nappaaluk alongside at BIO. |
I took the opportunity on Canadian Guard Guard Day at the Bedford Institute of Oceanography to tour the newest vessel in the fleet, the research vessel CCGS Naalak Nappaaluk - the replacement for the retired and broken up CCGS Hudson. This was the first time I actually got to set eyes on this ship, which only arrived on the East Coast recently after her delivery cruise from Vancouver where she was built.
Captions and explanations are based on my memory of the tour, and my recollections may not be 100% accurate.

| Hudson was commissioned in 1964 and retired in January 2002. |
 |
| A piece of Hudson herself wasn't far away - her old propeller sat on the jetty within sight - take a look at the dent in the blade on the right! |
The tour started on the aft working deck of the ship. If I am reading the rank insignia correctly (with the help of
Wikipedia), our guide was Deputy Superintendent Mullen (the ship's First Officer).
 |
| This boom is dedicated to launching sensors over the ship's transom to free up the larger crane and A-frame for other tasks. |
The blue launching equipment handles an array that measures seawater salinity and density. The array is towed up to a nautical mile behind the ship and provides a constant stream of data back to the ship.
On the aft deck, our guide explained that the deck itself is littered with small round covers - any of which can be removed and underneath are tie-downs that can be used to moor sea containers or other equipment.

The large yellow cranes in this photo were built by Hawbolt Industries in Chester, NS. From here, we headed up to the bridge. The steps and railings of the ship are heat traced to prevent ice buildup in cold weather conditions. The CCG is apparently moving away from Starlink for satellite communications and is using OneWeb, a Canadian solution. (OneWeb is apparently European, not Canadian).

| Looking to port at the ship's Fast Rescue Craft (or FRC). |
The ship has two boats, the FRC and a dedicated lifeboat. There are also several inflatable lifeboats such as the white cylinders to the left of the image.

| Port bridge helm station. |
 |
| The port helm station again. The semi-circle handles are used to control the ship's two azipods, and the lever between them is used to control the ship's bow thruster. |
In addition to the manual helm controls, the ship has a Dynamic Positioning system. Basically an auto-helm, it can be turned on at any time under 4 knots and will use GPS to maintain the ship's position in a single spot which is very useful when a Remotely Operated Vehicle (ROV) is deployed.
 |
| The ship's azipods have the propellers pointed forward to pull the ship through the water, rather than the more traditional push configuration. It was explained that this was to reduce interference with towed sensor packages. |

 |
| A typical twin cabin. The head is on the left. There are also single cabins. |
People sharing a twin cabin are often on different shifts, with one person sleeping while the other is working.
 |
| The interior of the oceanographic Conductivity, Temperature, and Depth (CTD) sampling room. |
The sampling bottles can be opened at both ends and the entire housing is sent to hover just above the ocean bottom and they can take samples at different water depths as it is brought back up to the ship. They can also deploy the plankton net to the right of our guide.
The ship will typically repeat certain runs at the same time every year (such as the "St. John's Run" where they go several hundred miles offshore) and visit the same spots to take samples and readings that can be compared year over year. There are also sensor buoys that take readings year round, and the data from the ship is compared against the data from the buoys to confirm continuity and consistency. The data is ultimately used to assess the health of the ocean.

I did ask who I should bribe in order to obtain a tour of the engine room but was told that it was a long list of people and that I probably didn't have enough cash on me for that purpose (or that I would have had to make arrangements in advance) or something like that. Maybe both.
In any case, it was described that the ship's powerplant is diesel electric, and that the diesel is housed in an acoustic enclosure to reduce noise and interference with the various sensor packages the ship will carry in service. In any event, we were told that one of the engines was running while we were onboard, and we could not hear anything or feel any vibration in the deck plates. In fact, our guide told us that there aren't even any signs requiring hearing protection at the entrance to the engine room.
It was also a good opportunity to get a close-up view of one of the CCG's Bell 412 EPI helicopters. This is a modern iteration of the legendary Huey.
Aside from the ship and helicopter tours, there were many other booths, tents, and displays showing what the CCG does, so if you are interested you should check it out next year.
