HMS Ocean is approaching the end of her upkeep period.
From an earlier Babcock press release;
Work to be undertaken includes over 60 upgrades. These include the new 997 Medium Range Radar system; four 30mm Automated Small Calibre Gun Systems to replace existing 20mm guns (involving installation of over 20,000 metres of power and control cabling); a new fire detection system; the Defence Information Infrastructure (Future) (DII(F)) enabling information sharing and collaborative working across the Armed Forces and MoD; and the DNA(2) Command System – the ‘brain’ of the ship and central to its fighting capability against air and surface threats.
Additionally, significant mechanical improvements include two major system installations, including a first-of-class Membrane Bio-Reactor (MBR) system which treats waste water and sewage to permit discharge at sea, and a further first-of-class ballast water treatment system. These will ensure the ship is compliant with new environmental legislation regarding treatment of ballast water and black and grey water discharges and able to operate anywhere in the world.
Other substantial work packages to be undertaken include major represervation work, and upgrades and improvements to living quarters including mess and recreational areas, cabins and bathrooms, as well as improvements to the laundry and sick bay complex, plus a full programme of deep maintenance
Instead of concentrating on the radar or shooty stuff, how about a look at that Membrane Bio Reactor?
The MBR has been supplied by Hamworthy, now a Wartisla company and is from the same family as installed on all the Type 45 destroyers and that to be (if not already) on the QE class aircraft carriers
Now that is what you call commonality!
A Membrane Bio Reactor is conceptually a very simple piece of equipment, it takes in grey and black water and turns it into clean water.
At a detailed engineering level, it is a whole lot more complicated.
Those on the Type 45 are installed in pairs, each with 6 membrane modules and able to process up to 100 cubic metres per day.
