A hugely significant objective was achieved on Saturday past, when the 2nd propeller of the Ship, which had been lying in Dry Docks since 2018, was re-united with its sibling, and is now Quay side for the first time ever. Both propellers are currently undergoing a makeover, being sandblasted, cleaned and then they will be repainted.

Attached are two of the many photos taken on Saturday, but as of right now, its fully enclosed for the maintenance work.

Thanks to Ferghal for this update on the propellers and we can look forward to more on the story of "Siblings Reunited" plus photos once the makeover is complete.

That's awesome, thanks Ferghal.

The two most powerful passenger ship propellors ever, I believe.

These are QE2's third set and propelled her approx. 2.9 million nautical miles. They were attached to her from July 1998 to 22 March 2018. Five-bladed / 6.1 metres diameter

Nice video from QE2 Dubai of the second propellor being maneuvered into position.

Great photo and nice video from Rob.

Michael - should the propellor dates be from July 1988?

290,000 miles a year over the last ten years of service seems a lot even for QE2!

She had 2 sets as a steam ship. Third set in 88 as a motor ship, then I dropped out of the picture.
Funnily enough, last night on you tube I watched a video of a propellor being made in Pakistan. It was about 4 feet in diameter.
But it was like someboidies back yard!

Heres a couple of other prop pics .
From the moment you first glimpsed the Queen,

These are very interesting photos! It is fascinating to discover the history of the QE2 propellers over the course of the years.

Could you please mention for each photo where you found it, so that the photographer or the publication can be credited. Also, if by any chance you know, could you add some information as to when and where these photos were taken? Those occasions when her propellers were exposed, were not that many in the course of her working life, and we are lucky to have these pictures at all. Thank you 😊

Thank-you to Ferghal Purcell General Manager, QE2 Dubai for sending photos showing the journey to reunite QE2's propellers.  It is good to know that the new feature has been well received in Dubai.

As previously mentioned, after years of sitting idly here in Dry Docks in Dubai, and months of persuasion, and at a significant cost, we reunited both propellers here at The QE2, after years apart.
 

Ferghal has given us the narrative composed by Michael Gallagher on the propellers.  Thank-you to Michael for letting us post this information.

Siblings Reunited : Twin Propellers of the QE2 1988-2018

Since her maiden voyage in 1969, the Queen Elizabeth 2 (QE2) stood as a testament to maritime engineering prowess. At the heart of her power and speed were her iconic propellers, an engineering marvel that defined her legacy. From her maiden voyage to her retirement, QE2 had three sets of propellers, which were the driving force behind her legendary journeys. Each set represented a chapter in her storied history, embodying the spirit of innovation and resilience that defined this iconic vessel.

Set One (1967 – October 1986)

When QE2 set sail, as a steam ship, she boasted the most powerful twin screw vessel in the world, thanks to her six-bladed, 5.8 meters in diameter propellers. Manufactured by Stone Manganese Marine, these solid cast steel unit of 65 tons propellers represented a breakthrough, utilizing cutting-edge design and extensive testing to eliminate vibration, ensuring a smooth voyage for passengers.

Set Two (November 1986 – July 1988)

In 1986, QE2 underwent a transformative reengining. The ship embraced a new era with a 5.8 -meter diameter, five-bladed, controllable pitch propellers from Dutch firm LIPs. These propellers, each weighing 42 tons, not only enhanced efficiency but by turning the controlled blades sufficiently, QE2 could be halted and then sent astern whilst the propellers still rotated in the same direction, a feat unheard of in cruise ships at the time. The controlled pitch of the blades would do the rest, enabling QE2 to go from 34 knots ahead to 19 knots astern – faster than most cruise ships could cruise forwards!

The new propellers were augmented by pseudo-propellers called Grim Wheels named after the German inventor Dr Ing Otto Grim. However, this experiment was short-lived. The Grim Wheels suffered an unforeseen failure when parts of it broke off on her return to Southampton from Bremerhaven, leading to their removal in 1987. Unfortunately, the QE2 had experienced vibration issues because of these propellers resulting in passenger discomfort and complaints. In 1988 Cunard decide to replace 5.8-meter propellers with a 6.1-meter set.

Set Three (July 1988 – 22 March 2018)

The third set of propellers, larger at 6.1 meters in diameter, marked a turning point. The increased diameter and blade configuration eliminated ‘tip vortex’ which had been identified as the source of the noise and vibration. QE2’s post-refit trials astonished crew members; she effortlessly reached 31 knots, proving noise and vibration issues were a thing of the past. Over her years of service, these propellers were meticulously maintained, enduring multiple inspections and refits to ensure QE2’s continued excellence.

Spare Six-Bladed Set (1967 – 1990)

Cunard's foresight led to the creation of a spare set, a strategic move that would ensure QE2’s uninterrupted service. Stored in Southampton docks, these propellers remained on standby, ready to be deployed if needed. Although never used in service, their fate took an unexpected turn when they found new life as golf clubs, a unique transformation that echoes the ship’s legacy of innovation and adaptability.

The set of propellers you see before you are the third and final set, used on the QE2 from 1988 to 2008. During which time they have sailed over 3 million nautical miles. The only pair of propellers in the UAE to have travelled such a distance. A mammoth testament to the QE2’s legacy and heritage.

I see that the "spare" set brought to Dubai were transported by  "the QE 2 Story's" own transportation.

Now THAT shows class!

… Possibly of related interest…the original set of spare 6-bladed props were carried on the foredeck of the QE2. At least from the Clyde to her first call into Southampton. I have a snapshot of at least one, taken from the port bridge wing, showing the prop mounted down below.
