The biggest of the three, she was meant to raise the bar yet again. Since Britannic was still under construction, the shipbuilders were able to modify the ship's safety design without completely rebuilding it. Olympic spent five months in dry dock after the disaster getting retrofitted with higher bulkheads, additional lifeboats and a double hull skin that encapsulated the lower hull. These same safety features we added to Britannic as well. Another bulkhead was added, giving Britannic seventeen watertight compartments instead of sixteen like her sisters.
Britannic's most striking visual distinction were the installation of enormous crane style davits. These allowed stacks of boats be carried in the same space as a sing row of bows on her older sisters. Ultimately 55 boats were installed on the ship, including two that were motorized, a first for the class.
Some of the common rooms were repositioned. The aft well deck was enclosed, giving the third class a covered promenade. The third class smoking room was moved above the general room on the poop deck, giving the stern a larger appearance. The second class was given a gymnasium. Every luxury feature on Britannic was upgraded. The grand staircase was modified to include a vast pipe organ.
This organ was never installed as Britannic was pressed into service as a hospital ship and sunk. I have always been curious about the 'last-minute' decision to add a glass-enclosed area to Titanic's forward A deck promenade. It has always been characterized as being installed to protect First Class passengers from sea spray.
I find this reason spurious. Thomas Andrews had noted unusual metal fatigue occurring just where the Olympic reached full beam at the bow when the Olympic was in dry dock following the HMS Hawke collision.
He ordered further reinforcement to the area near the full-beam section of Titanic at a critical joint. Olympic was completed and launched almost exactly twelve months before her infamous sister ship on September 20, , and she had a successful maiden voyage on June 14, Strangely, for all the fanfare Titanic receives for its superiority to other liners of her day, it is amazing how similar the Olympic and Titanic are.
Titanic was fractionally larger than the Olympic with best estimates being only some 3 inches favouring the Titanic but over tonnes heavier in gross tonnage than Olympic.
A complete unit of work to teach students about the historical and cultural impact Titanic made upon the world both back in the early 20th century as the worlds grandest liner, and as a tragic metaphor after she sank during her maiden voyage. This complete unit includes. Well-received by patrons, the Olympic found minor tragedy when it was struck by the military cruiser the HMS Hawke.
She returned to Belfast and was repaired using parts from the Titanic, which was currently under construction. Olympic was fitted out for a different clientele to Titanic and had very little of the lavish affection to detail, craftsmanship and opulence that Titanic was to offer later.
In saying this, Olympic was a grand ship for her era and had many cutting edge features which set her above her peers.
After the Titanic disaster, Olympic revisited the Harland and Wolff dry-dock for various safety improvements, including lifeboats for all aboard. In October Olympic returned to Belfast again to install an inner watertight skin.
In October of , Olympic assisted the sinking British battleship Audaciously and conducted a daring at-sea rescue. During the remainder of the first world war, Olympic served as a troopship carrying Canadians to the European war front.
Her most famous wartime moment, and perhaps the most famous moment of all of the Titanic sisters is when the Olympic struck and sank a German submarine, U Follow the shortlink to see this new addition. Thank you.
Olympic arrived in Southampton in late April after Titanic sank. After provisioning the Olympic was due to sail again, however the black gang mutinied over the collapsible boats that had been added to Olympic after Titanic sank.
The black gang did not believe the collapsible boats were safe. This was not settled until May 4. Although, wikipedia states that Olympic was withdrawn from service and sent to the builders for the refit on 9 October , I believe the correct date was actually 9 September Encyclopedia Titanica is one of the best sites on the web for information and forum discussions about the Titanic and her sister ships.

I am a professional author and cannot take time away from current projects to rehash the same comments over and over and over again. Nor does my staff have the time to cater only to Titanic fanatics. Kas01 Member. The problem with your statement, Mike, is that the Olympic- class came off the slipways with outboard screws powered by triple expansion engines, not quadruple expansion as was the case with Megantic stupid name, in my not-so-humble opinion.
The centerline screw was the turbine. Now the big thing was that, in service and at speed, Lucy not only vibrated, but vibrated so badly that unless some young lassies in steerage were ridiculously desperate for some special alone time, both second class and steerage were damn near uninhabitable. Jim Currie Member. The most important statistic concerning a merchant ship Basically, this means the amount of useable cubic space. A ship has two basic tonnages Gross and Displacement.
In m Gross tonnage was reckoned in units of cubic feet to the long ton. Displacement tonnage was simply the weight of water displaced by the ship when she floated. It was the weight of the ship and everything in her at a given time. The statistics Olympic and Titanic were as follows: Olympic. Gross 45, tons.
Displacement 52, tons. Differences 1, tons tons. The foregoing tells us that a Light ship, Titanic was tons heavier than a light ship Olympic and had , extra useable cubic capacity. However, the external dimensions of the ships were almost the same. Unlike, Olympic , the forward end of Titanic's A deck on each side was enclosed. This area alone was almost enough to account for the extra gross tons. The extra steel, brass, and glass required for that enclosure would account for part of the ton weight difference but not all of it.
Hope this helps. Military ships had been using turbines for only a few years when the Olympic class went on the drawing boards. HMS Dreadnought was the first all turbine warship when it was launched in A Navy can justify taking risks on new equipment if that results in a more effective warship. You only get one chance to lose a war. Lusitania, Cunard's first 4-stack greyhound, was built with all Parsons turbines.
I have seen it published that Lucy's props were coupled to the turbines because reduction gears suitable to handle the power did not yet exist. This forced the ship's turbines to rotate far slower than the RPM for maximum efficiency. This problem was most noticed at slower speeds and less at high. In other words, the Parsons prime movers were far from perfect. They were more of a glimpse of the future than the best solution for a ship in the first decade of the 20th century.
Notice a turbine powered the center shaft of the design. As I recall, this turbine operated on less than ambient air pressure. It used the low pressure created by cooling steam from the two reciprocating engines. Good idea for squeezing every last ounce of thrust out of that expensive coal in the bunkers. Once reduction gears caught up with the power demands, turbines were able to run at more efficient speeds. That did not happen until about mid-way through WW-1 and four years after Titanic sank.
Even so, there is no clutch pedal or gear shift lever on a steam turbine. They all rotate in one direction. This makes slowing, stopping, and backing down a problem. The installations I've seen solve the problem by adding a smaller reversing turbine.
Steam is normally fed to the forward machine. If reverse is necessary, the engineers have to shut down steam to the forward turbine and then open the valves for the reversing turbine.
