"
gradually
the skeleton in the scaffolding began to take shape. It was the shape
of a ship; a ship so enormous that men held their breaths at the sight
of it. With propellers the size of windmills and a rudder the size of
an elm tree; everything was on a nightmare scale."
It
was true that the world had never seen the likes of Olympic and
Titanic. No moving object had ever been crafted by the hand of
man. No ship had ever been constructed in such a manner. It was with great
pride that Lord Pirrie watched the two ships rise up from the steel work.
Everything about them, from their very construction to the gantries over
top of them, was sure to propel Harland & Wolff to the forefront of
the shipbuilding industry. Through its use of new and innovative
technology, the ship builders were hoping to set a precedent that all
other shipbuilders would follow or die trying (the latter was preferable).
As Titanics frame work was built, Olympic was being
plated. The steel plates were 1 in. thick, 30 ft. long and 6 ft. wide.
The plates were exceptionally heavy as compared to those used on other
ships, but as speed was not a consideration, they were necessary to provide
the strength needed. The plates were riveted to the frame of the ship
in horizontal rows known as strakes. The strakes overlapped each other
in joggles, with each strake having an in or out joggle. This was necessary
to provide enough material to rivet the strakes together but prevented
the ships from having a smooth outer hull. Interestingly enough, todays
ship use steel plates in the same 30 ft. by 6 ft. dimensions but the plates
are welded together at the edges to provide a smooth, seamless hull profile.
Olympic
and Titanic had a classic triple-deck superstructure, the uppermost
decks comprising the Boat, Promenade and Bridge decks. Although standard
shipbuilding practices allowed for the use of lighter materials to be
used in this design to avoid making the ship top heavy and susceptible
to rolling in heavy seas as well as making the ships lighter and therefor
faster, the builders again noted that speed was not the consideration
and that the ships were perfectly square amidships and therefor extremely
stable. The superstructure was constructed according to the same specifications
as the outer hull and internal structure so as to provide the highest
level of structural rigidity. An additional design feature was the incorporation
of expansion joints above the Bridge deck that completely severed the
superstructure. As large and complex as the ships were, provisions had
to be made for the structure to flex. Without the expansion joints, the
ship would snap like a twig. The joints were literally hinges, composed
of leather, steel and iron riveted to the deck plates. They allowed for
as much as two feet of hull deflection from the horizontal plane. The
expansion joints were designed to counter the stresses placed on the hull
when the ship hogged or sagged. Hogging is when the hull is supported
in the middle by a large wave, leaving the bow and stern unsupported.
Gravity then pulls those areas of the ship down, causing the vessel to
take on a banana shape. Sagging is the opposite; a ship is supported at
the bow and stern by waves, leaving the middle of the hull unsupported.
The ships midsection then sags down into the trough of the wave.
Today, in lieu of expansion joints, special steels and internal bracing
compensate for this flexing on large vessels.
The two White Star sisters were constructed
by over 15,000 men who worked long hours hammering the ships into being.
They were skilled craftsmen who took great pride in their work. They were
accustomed to working on a tight schedule and work proceeded at a lightning
pace. According to legend, it was during the plating of Titanic
that she claimed her first victim. A worker was accidentally sealed inside
the lining of the hull when he crawled between the layers of the double
bottom to check the internal riveting. As horrifying as it sounds, this
was not uncommon for the period, given the pace at which new ships were
constructed. Unfortunately, once the plates had been riveted, there was
no way to rescue the man. The cost of removing the rivets and the damage
to the hull and frame work in doing so made for a hopeless situation.
His screams were inaudible through the heavy plates, the banging of his
hammer was the only indication that he was still alive. That soon faded
and stopped altogether as he ran out of air. Accidents
and mishaps aside, construction proceeded at breakneck speed. Nothing
was allowed to impede the progress of construction. Too much was at stake.
The Cunard Lines new ships were dominating the North Atlantic and
White Star needed to get its new liners into service as soon as
possible. Olympics hull was completed and launched on October
20, 1910. Titanic was not alone for long, though. The keel for
Gigantic was laid not long after Olympics launch.
After being towed to the new Thompson Graving Dock, Olympic underwent
seven months of fitting out before she was completed. Then, after two
days of sea trials, she was handed over to White Star on May 31, 1911
in Belfast Harbour. This same day, Titanics completed hull
was launched into the River Lagen.
Titanics launch was witnessed
by thousands of people who gathered on ships and on the shore of the River
Lagen to see White Star's newest leviathan go into the water for the first
time. No doubt hundreds of ships had been launched from the Harland &
Wolff shipyard. I'm not sure but am fairly confident a crowd was gathered
for each and every launch. None, I doubt, drew as much as attention as
the launch of one of the world's two largest liners. None of those could
imagine, however, just how pivitol a role this particular ship would play
in history. Also on hand to for the event was Bruce Ismay, Lord Pirrie
and J.P. Morgan. At 12:13 on May 31st, 1911, the order was given to release
the hydraulic launch triggers that held the hull in place as the workmen
knocked away the wooden supports. James Dobbins, a worker in the shipyard,
was struck and fatally injured by one of the falling timbers. Titanic
claimed her second life as she began
to move down the slipway, which was lubricated with 22 tons of slick tallow,
oil and soap. It took Titanic 62 seconds to slide down the slipway
and into the water. In that time she traveled nearly twice her length
and achieved a speed of 12 knots before being brought to a halt by six
anchor chains and two piles of drag chains that weighed 80 tons each.
For a few short hours she and the newly completed Olympic could
be seen floating together. At 3:00 Bruce Ismay and his party sailed for
Liverpool aboard Olympic and Titanic was towed to the fitting
out basin for the next phase of her construction.
The
installation of Titanics majestic interiors as well as her
heavy machinery and other fittings took ten months and several million
man hours. It was intended that she be even more luxurious than her predecessor.
Between teak from Siam and fabrics from Holland, every aspect of Titanics
fitting out was aimed at making her the most amazing vessel the world
had ever seen. In place of Olympics hard wood floors, Titanic
was given thick carpeting that one worker described as "so thick
you sank in it up to your knees." Craftsmen worked long hours to
adorn her with stained-glass and ornate chandeliers and intricately carved
oak paneling. In a special edition devoted to the new liners, the prestigious
industry journal The Shipbuilder reported that the greatest pains were
being taken "to provide passenger accommodations of unrivaled extent
and magnificence
the excellent result defies improvement." Improving
on Olympics design, many additions were made to Titanic
that would redefine the ocean travelers experience even more so
than her predecessor. Already a thousand tons heavier than her sister
ship, Titanic boasted many refinements that made her far more luxurious
as well. Her first class restaurant was enlarged and included a trellised
replica of a French sidewalk café; the Café Parisien. Two
First Class suites were built on B Deck, these staterooms had private
promenades, which necessetated alterations to the B Deck window arrangement.
The forward half of the first class promenade on A Deck was also enclosed
with glass to eliminate the annoying sea spray that some of Olympics
first class passengers had complained about. These two differences between
the sisters is the easiest way to tell them apart when looking at photographs.
In
January of 1912, Titanics lifeboats were installed. The original
design had called for 64 wooden lifeboats. The new Walin Davits being
used on the ship were capable of carrying up to three boats each. A number
of factors, however, lead to the drastic reduction in the number of lifeboats
installed on Olympic and subsequently Titanic. First was
the fact that so many boats would hardly be necessary because even in
the event of a catastrophe it would take some time for the ships to sink.
The lifeboats would be no more than ferries to carry passengers to nearby
rescue ships. Lifeboats would also clutter up the deck and make it difficult
for first class passengers to move about the Boat Deck freely. The deciding
factor was the fact that the British Board of Trade regulations regarding
such matters required that any boat over 10,000 tons carry a minimum of
16 life lifeboats.
The
regulations had not been updated in decades and Titanics
registered weight was 46,000 tons. When all was said and done, Titanic
was fitted with 14 standard design lifeboats capable of carrying 65 people
apiece and were stowed on launch cradles, 2 emergency cutters which carried
40 people each and were permanently swung out on either side of the bridge,
and four "Engelhardt" boats with collapsible canvas sides that
could hold 47 people and were stowed on the roof of the officers
quarters on either side of the forward funnel. The total capacity of these
boats was 1,178 people if they were fully loaded. Titanics
total capacity; passengers and crew, if fully loaded was 3,300. Despite
this scandalous ratio of lifeboats to people, the regulations set forth
by the B.O.T. were actually exceeded.
Titanic was successfully dry-docked
at the Thompson Graving Dock in Belfast Harbour on February 3rd, 1912.
Here she was fitted with her three propellers and a final coat of paint
was applied. Red anti-fouling paint was applied from her bottom to just
above the water line. The rest of the hull was painted black and the superstructure
white. The funnels were White Star's traditional beige with a band of
black on top. In early March 1912, Titanic is removed from drydock
so that Olympic can be repaired; she lost a propeller to an underwater
obstruction. Titanic's starboard propeller is removed and fitted
to her sister ship to quicken the repair. A new propeller is soon fitted
to Titanic and she is completed at the end of March. On
April 2, she leeaves Belfast on her sea trials. Under the command of Captain
Bartlett, her various equipment is tested, and speed and handling trials
are undertaken, including turning and start-stop maneuvers. Titanic
is run full speed at 20 knots and then stopped with engines at full astern.
For the next few hours she runs at 18 knots out in the Irish Sea before
returning to Belfast in the early evening. Titanic meets all B.O.T.
criteria for sea-worthiness in less than a day and is granted permission
to sail for her point of embarkation, Southampton.
