Whilst browsing I noticed the following short sequence of tweets the other day.
Note; some tweets carry interesting exchanges in the comments.

An exciting day for me today as the V-Sat, which will provide all our comms needs on the RRS Sir David Attenborough, is unpacked and put together. It will be lifted into place next week....weather permitting! @BAS_News

Dome building has continued today. 6 petals on the base and 6 for the top. Tomorrow the completed top will be lifted into place and sealed with silicone, allowed to cure and then the complte dome will be lifted onto the main mast @BAS_News

With all the electronices tested the top section of the dome is lowered into place. Lots of screws and silicon sealant and it is now fully waterproof and ready to be lifted onto the main mast of the RRS Sir David Attenborough @BAS_News

The most complex non-naval vessel constructed in the UK for many years - RRS Sir David Attenborough will be formally named by the Duchess of Cambridge at @CammellLaird today.

The following excerpt is copied from the BAS NERC (British Antarctic Survey - Natural Environment Research Council) website.
Page titled BAS > Polar operations > Offices, labs and research facilities > ICT facilities
ICT facilities
About
RRS Sir David Attenborough will be equipped with enhanced satellite communications and data processing and storage systems to meet the increasing requirement for data-intensive operations (including operational forecasting).
Communications
The ship’s telephone and PA network, SeaQNet, is part of the BAS Cambridge network. This means that all telephones on the ship will have an internal BAS telephone number.
Communications will take place via VSAT satellite; the bandwidth will initially be 1.5-3 Mb/s, approximately double that available on RRS James Clark Ross.
Aboard ship, WiFi will cover all locations (including cabins) on Deck 3 and above, with some locations on Deck 2 also covered.
Scientific computing
The vessel will operate a system called SDANet, with a 10 Gb/s server connections and 1 Gb/s connections to desktop computers. Approximately 900 network ports will be distributed around the ship, and SDANet will be used for most communications with instruments aboard the ship.
There is uncommitted scientific wiring available on the ship for use in future applications.
Data displays
The RRS Sir David Attenborough will have a total of approximately 180 24-inch display screens distributed throughout the ship. This includes large video walls (2×2 and 4×3 screens), which can be used as a single large screen or split up, as well as 2- and 4-screen operator workstations in the main lab and winch control room. Each lab space will also have several display screens.
There will be more than 30 sources for these displays, including the ship’s navigation systems, bridge displays and scientific computers.
The video walls and operator workstations have fibre optic cabling which allows for future upgrades to 4k usage. The single displays will initially operate using copper cabling which can support full HD (1920×1200) resolution and may also be upgradable to 4k.
Data management
While RRS James Clark Ross produces up to 3TB of data per research cruise, the new ship will have significantly more instruments and expanded scientific capability on board. As such, the amount of data generated is expected to be significantly greater, up to several 100 TB per cruise.
Data logging systems with sufficient capacity for logging information from stream-based devices such as meteorological, oceanographic and navigational instruments will be installed on the ship. There will also be a central file server for instruments such as swath bathymetry, fisheries echosounders and the ADCP.
