Sonar

"The FarSounder sonar was chosen to compliment the other navigation and science mission sensors onboard. Farsounder’s primary purpose however is for safe navigation and obstacle avoidance. Onboard the RRS Sir David Attenborough it will be used to detect ice. The sonar is protected during icebreaking operations via a custom hoist.." [32], [33]

"FarSounder’s navigation systems are the only products capable of generating a true, 3-dimensional image ahead of a vessel at navigationally significant ranges at each ping of the sonar. The Farsounder 1000 will provide a 3-dimensional image ahead of a vessel in real-time. Operational and reliable at navigationally significant ranges up to 1000 metres and speeds up to 25 knots. Icebergs and growlers are very good acoustic targets and are of concern to many yacht and ship operators. A number of the Farsounder Argos series are installed on ice classed hulls specifically for ice detection. They have fast refresh rates and a wide field of view with every single ping which allows users to navigate safely and confidently with ice-navigation by providing a 3D image ahead of the vessel." [32], [33]

Radars

"Two of Rutter’s sigma S6 systems will be installed on the ship: sigma S6 Ice Navigator™, [22] and integrated sigma S6 Oil Spill Detection [21] and WaMoS® II Wave and Surface Current Monitoring. The ice system will provide imaging and detection for safe navigation in polar seas, while the objective of the integrated oil and wave/surface current measurement system is to collect data for scientific research." [20], [21], [22]

"Dartcom has recently supplied and installed [1.5m Marine X/L-Band EOS Systems] on two new polar research vessels – the Australian Antarctic Division’s [RSV Nuyina] and the British Antarctic Survey’s [RRS Sir David Attenborough]." [30], [31]

Mounts

N/A

Aircraft & Docking Facilities

1x Pad for Medium Helicopter [5]
2x Hanger for Small Helicopter [5]
660m³ of Aviation Fuel, 840kg/m3, 840 x 660 = 55,4400kg = 554.4 metric tonnes. [7], [8]
Cargo hold has a volume of 2,100m³ . [7]
"The new polar ship has a workboat, Erebus, and cargo tender, Terror, which can approach [Bird Island] and [Signy] research stations during resupply operations. This is important because the water near these stations is too shallow for the ship to approach. There are also some small, inflatable craft aboard the ship." [7]

Erebus – the workboat

_"Erebus is a small, 10m research vessel that will enable scientists to carry out research in shallow, inshore waters, and transport people and supplies to and from our island stations."_ [7] "She is fitted with a multi-frequency echosounder, for identifying and quantifying pelagic organisms; a shallow-water swatch bathymetry system, for mapping and imaging the seafloor; and a hydraulic stern davit and winch for sampling operations and deploying small equipment. Erebus can also support science diving operations."_ [7]

Terror – the cargo tender

"The cargo tender will transfer supplies such as food, fuel and science equipment onto land at stations and places that the RRS Sir David Attenborough cannot access. To assist with this work, Terror is fitted with a crane that can lift up to 1t loads @ 8m." [7]

"Launch and recovery of aerial and ocean robotic systems" [1], [11]

Comments

"Ice breaking capability – up to 1m thick at 3 knots (5.6 km/h)." [1]
"Endurance – up to 60 days." [1]
"Bow and stern thrusters for excellent dynamic positioning in challenging conditions." [1]
"Engines are designed to run as silently as possible, and special attention is given to avoiding sweep-down of bubbles around the hull that could interfere with acoustic sensors." [6]
"Extremely low underwater radiated noise to avoid interference with survey equipment or disturbance to marine mammals or fish distribution." [6], [10]
Acoustic survey speed (meeting Silent R requirement) 11 Knots. [24]

Towing mode 5-6 Knots. [24]

          **As a side note the virtual tour of this ship is pretty cool see reference number [5]**

I like that whoever was in charge of the IET PDF (source 25) called it "boaty.pdf."

Still mad they didn't name the ship "Boaty McBoatface."

In source 9 its shows some form of mini sub that has the boaty name attached.

PygmalionOfCyprus commented 2 years ago

Added 494. Did a little handwaving on some of the sensors and features since a lot of the special survey-specific equipment is out-of-scope for Command. But I think it'll do the trick.

I didn't add Erebus or Terror, but if you really want those, you can put in separate ship requests for each so we can get a data dump.

5th-Domain commented 2 years ago

I will look at Erebus and Terror and generate some new tickets if i can find enough detail on them.

PygmalionOfCyprus commented 2 years ago

Worst case scenario if you can find some representative data we could add a generic tender and generic workboat.

5th-Domain commented 2 years ago

I think there is a small motor survey boat in the database so i'll look at that see how it matches up for Erebus and i think Terror will be just like a small landing craft so i'll see if anything in the DB is currently small enough. I'll have a look this evening.
