Titanic Sister Ships


Responding to competition from Cunard, whose ships Lusitania and Mauretania were setting new records for speed and new standards of luxury, the White Star Line decided to build three new liners, Olympic, Titanic and Britannic. Rather than compete on speed, this new breed of olympic class ocean liner would be the largest at sea.

Olympic was the first sister ship to be built, replacing the SS Teutonic. Titanic was intended to replace the SS Majestic (although the Majestic recommenced the New York route following the sinking of the Titanic). Finally Britannic, although intended to form part of an impressive trio, would only launch after the Titanic had been lost, and was herself destined to sink also.

RMS Olympic

16 December 1908 – the date the keel was laid down and construction commenced.

20 October 1910 – the date Olympic was launched, the first of the trio of White Star Liners comprising Olympic and the sister ships Titanic and Britannic.

22 months – the length of time it took to build the Olympic, from keel to launch.

How Big Was The Olympic?

45,324 GRT – the gross register tons at launch.

46,358 GRT – the gross register tons from 1913.

46,439 GRT – the gross register tons from 1920.

52,067 tons – the ship’s displacement.

882 feet 6 inches – the length of the Olympic (269 metres).

92 feet 6 inches – the beam (28.2 metres).

175 feet – the height of the ship, from keel to the top of the funnels (53.3 metres).

10 – the number of decks.

2 – the number of rockets that were fired at 10:50 am, to signal the imminent launch of the ship.

11.00 am – the time Olympic was launched, accompanied by the firing of another, single rocket.

12.5 knots – the approximate speed that Olympic entered the water.

62 seconds – the time it took Olympic to enter the water, sliding down slipway number 2 on a thick layer of soap and tallow.

20,600 tons – the weight of Olympic’s hull at launch. She was then moored, ready for fitting out, at Alexandria Wharf.

01 April 1911 – the date Olympic entered the Thompson dry dock for final completion. Here her propellers were installed and her hull painted.

27 May 1911 – the date of an open day, where members of the public could board and explore the ship.

5 shillings – the cost of entry for the open day, with all the money raised being donated to local Belfast hospitals.

29 May 1911 – the date that the Olympic sea trials commenced.

04:30 pm – the time at which Olympic departed for Liverpool, the same day.

01 June 1911 – the date Olympic arrived in Liverpool, where she would briefly stay before sailing for Southampton, the port from which she would commence her maiden voyage.

02 June 1911 – the date Olympic left for Southampton, departing Liverpool shortly after midnight.

03 June 1911 – the date Olympic arrived in Southampton.

Olympic Maiden Voyage

14 June 1911 – the date of Olympic’s maiden voyage to New York, also under the command of the future captain of the Titanic, Edward J Smith.

2,590 – the number of passengers Olympic was registered to carry (1,054 first class, 510 second class, 1,026 third class).

1,313 – the number of passengers who embarked for the maiden voyage from Southampton (489 first class, 263 second class, 561 third class).

21 June 1911 – the date Olympic arrived at the White Star Line’s Pier 59 in New York.

650 tons – the daily coal consumption for the crossing (five single-ended boilers were not used, reducing speed and saving fuel).

2,894 miles – the distance travelled between Daunt’s Rock, near the entrance to Cork Harbour in Ireland, and the Ambrose Channel lightship, New York.

5 days, 16 hours, 42 minutes – the duration of the main Ireland to New York leg (the time calculated between Daunt’s Rock and the Ambrose Channel lightship.

21.17 knots – the average speed of the crossing.

Note: the duration and speed of the crossing, reported consistently for almost a century, have more recently been questioned. Possible errors in calculating the duration between start and finish, which occurred in differing time zones, reflect evidence from Captain Smith that Olympic sailed around 3 hours late. A new calculation, researched and written for the Titanic International Society and published in 2006, propose the following corrections:

5 days, 15 hours, 2 minutes – the revised duration of the journey between Daunt’s Rock and the Ambrose Channel lightship.

21.43 knots – the revised average speed of the crossing.

20 September 1911 – the date on which Olympic was involved in a collision with the cruiser HMS Hawke, and needed to return to the Harland & Wolff shipyard in Belfast, where she was repaired using parts from Titanic, which was then still under construction.

6 weeks – the length of time Olympic was out of action following the collision with HMS Hawke. Olympic’s stern was punctured and the bow of Hawke stove in.

01 September 1915 – the date the British Government requisitioned Olympic for war service as a troopship.

15th May 1934 – the date the Olympic was involved in a collision with a Nantucket lightship.

7 – the number of lives lost in the collision.

12 April 1935 – the date Olympic completed her final voyage, arriving back in Southampton.

24 – the number of years Olympic was in service before being retired.

13 October 1935 – the date the ship arrived at Palmers Yard in Jarrow on the Tyne ready for the superstructure to be broken up.

19 September 1937 – the date the broken remains of the RMS Olympic were towed to Inverkeithing, Scotland to complete her demolition of her hull.

51,680 – the gross tonnage of SS Imperator, the ship that stole the crown of largest ocean liner from Olympic. Built for the Hamburg America Line (otherwise known as the Hamburg Amerikanische Paketfahrt Aktien Gesellschaft, or ‘HAPAG’ for short) she was launched on 23 May 1912.

HMHS Britannic

30 November 1911 – the date Britannic’s keel was laid down and building work begun.

26 February 1914 – the date Britannic was launched, the build taking longer due to the need to redirect labour and materials to the war effort. In addition, following the Titanic disaster time was required to implement safety changes, such as the installation of a double hull along the engine and boiler rooms, and raising six of 15 watertight bulkheads to a higher deck.

27 months – the length of time it took to build the Britannic, from keel to launch.

Did You Know?

It was claimed that this ship was due to be named Gigantic, with a change of name being deemed necessary following the loss of the Titanic (a claim that White Star Line and Harland & Wolff always denied).

13 November 1915 – the date that Britannic was requisitioned for use as a hospital ship in the First World War (HMHS is short for His Majesty’s Hospital Ship).

9 – the number of decks.

12 November 1916 – the date Britannic departed Southampton on what would be her final voyage, returning to the Mediterranean for the sixth time in her service.

Did You Know?
