Oldest Type 23 frigate sails on-time, on-budget

Type 23 frigate HMS Argyll left Rosyth today (Friday 10 September) three days early, within budget, and fighting fit with enhanced sustainability and fighting capability, following a successful and demanding 11 month upkeep period by Babcock.

As the oldest Type 23 frigate in the fleet (and the first to undergo a second refit, or RP2) this complex project has involved a number of challenges, which Babcock has successfully addressed working closely with ship's staff and the MoD.

The 290,000 manhour project has involved a full deep maintenance programme and overhaul of mechanical systems, including replacing two of the vessel's four diesel generators, one of the gas turbines, 60 per cent of the main shaft lines, and complete overhaul of all the underwater and high pressure air and salt water system valves.

Significant focus has centred on the hull structure (which has benefitted from a substantial refurbishment package) and renewal of the flight deck. HMS Argyll is the first Royal Navy ship to have had the raised wooden flight deck replaced with a new composite material, involving a number of first-fit challenges which had to be absorbed into the programme schedule.

Major upgrades to the command and weapon systems have included the main armament, with the 4.5 inch Mk8 Mod1 gun fit. HMS Argyll has also received the new DNA(2) Command System (central to the ship's fighting capability against air, surface and underwater threats); the SeaWolf mid-life update (SWMLU) comprising tracking, guidance, and weapon management upgrades to counter evolving air and anti-ship missile threats; and the new Defence Information Infrastructure (Future) (DII(F)) system to enable information sharing and collaborative working across the Armed Forces and MoD. Further upgrades include 30mm automatic gun mounts, and boat davits. Additionally, living and working conditions on board in even the warmest climates have been improved with a 'globalisation' fit of the entire ship's ventilation; an upgrade that has affected nearly every compartment of the ship and required careful management of its interface with other work.

The refit contract, awarded under the Surface Ship Support Alliance (the alliance between the MoD, Babcock and BAE Systems), has benefitted throughout from the continuing supportive working relations and close partnering between Babcock, ship's staff and the MoD, to keep the programme on schedule and return HMS Argyll to the fleet on-time and in-budget, delivering optimum value for money.

Among initiatives to help achieve this, the project management team worked from the outset towards achieving two major milestones earlier than planned, including undocking seven days early, and ship's staff moving on board ten days ahead of schedule. This allowed ship's staff more time to re-familiarise themselves with their ship, and de-risk the downstream programme in the drive to meet Ready for Sea Date inspection - successfully achieved three days early.

Commenting on the project, Babcock project manager George White said: "Although challenging at times, the project has been a good one to be involved in and has shown that through successful partnering between all stakeholders (Babcock, ship's company and MoD) we can drive a diverse and complex project to a successful conclusion, within budget, achieving major milestones early to benefit the end user in the Royal Navy."

Jason Marshall, Project Contract Manager, said "This has been a demanding project due to the emergence of several unexpected material issues, however the determined positive approach of Babcock and ship's staff has ensured the best possible outcomes and that it has always remained a pleasure to be involved. The approach of targeting stretch dates for key milestones has delivered huge benefits and allowed the achievement of this significant evolution on schedule despite several set backs."

HMS Argyll has now left Rosyth for sea trials.
