ss
Great Eastern
The ss Great Eastern was conceived as the biggest steamship yet to be built,
one that would be capable of carrying 4,000 passengers at a time on a non-stop
trip to Australia.
Brunel was partnered in the venture by John Scott Russell, who he had met
during preparations for the Great Exhibition of 1851. Their proposal was
offered to the Eastern Steam Navigation Company who were looking for new
business interests. Brunel placed a number of his own nominees on the company
board and contributed considerable personal sums to the capital needed.
Scott Russell’s engineering firm was awarded the contract to construct
the ship. Work began at Napier Yard in Millwall in 1853. Brunel wrote:
I never embarked on one thing to which I have so entirely devoted myself,
and to which I have devoted so much time, thought and labour, on the success
of which I have staked my reputation, and to which I have so largely committed
myself and those who were disposed to place faith in me; nor was I ever
engaged in a work which from its nature required for its conduct and success
that it should be entrusted so entirely to my individual management and
control...
The ship, originally called Leviathan, was to be nearly 700ft/213.36m long,
six times the size of the largest ship built to date. Brunel designed her
to be unsinkable, extending the watertight double plating to five ft/1.5m
above the ship’s deepest load line. In addition, iron bulkheads divided
the ship into ten watertight compartments. To move such a large ship required
two engines, one attached to a screw propeller and built by James Watt &
Co, the other used to drive two enormous paddle wheels, built by Scott Russell.
The ship was constructed parallel to the riverbank with the intention of
easing her sideways down specially constructed slipways and floating her
off on high tide: her size meant a normal launch was impossible.
John Pudney has described the division of labour between the two partners
as Scott Russell being in charge of the hardware and Brunel in charge of
the paper. The relationship soon deteriorated. Things came to a head on
4 February 1856 when Scott Russell was declared bankrupt having kept the
precariousness of his financial situation hidden from his partner. Work
came to a halt and the accountants and bankers argued over the fate of the
half-finished ship. With considerable effort, more money was raised and
Brunel assumed full control of the project. However, he struggled to win
over Scott Russell’s men, who proved uncooperative, progress was slow
and there were endless contractual arguments.
Under threat of another bankruptcy should there be further delays, there
was an attempt to launch the hull on 3 November 1857 using untried and inadequate
equipment. Brunel had originally planned to use hydraulic launching gear
specially built for the project but because of the financial difficulties
this was judged by the company to be too expensive and he had to use steam
winches and capstans worked by teams of men. To further complicate an already
risky procedure, the company, seeking to make money, had sold tickets to
the public to attend the launch event and the yard was overrun with onlookers,
getting in the way of Brunel’s system of signals. The launch was a
disaster and the attempt abandoned.
Brunel tried again on the 19th and 28th, but to little effect. The failure
of the winch system led Brunel to turn to the use of hydraulic jacks to
push the ship down the slope. These were not up to a job of this magnitude
and after ten weeks of the ship inching painfully forward, Brunel stopped
the work in mid-December until better equipment could be obtained. This
was built by the Tangye brothers, based in Birmingham, who would later boast
‘we launched the Great Eastern and she launched us’.
With the new hydraulic rams in place and the loan of the hydraulic press
used by Robert Stephenson for his Britannia Bridge project, progress improved
in January, although bad weather caused further delays. At 1.42pm on 31
January 1858 the ship finally floated and was moved to Deptford for fitting
out. A new company, the Great Ship Company, was formed in November 1858
to undertake completion of the work and the Eastern Steam Navigation Company
was dissolved.
Sea trials were planned for 7 September 1859 but were postponed to the 9th
(Brunel was bedridden having collapsed on deck four days before). In the
haste to be ready, two temporary stop cocks fitted to the heaters on two
of the ship’s funnels were left in place, causing a devastating explosion
that killed five men and injured several others. News of the disaster is
thought to have hastened Brunel’s death.
The ss Great Eastern proved uneconomic as a passenger ship but had a new
lease of life when she was used to lay the first successful trans-Atlantic
cable. Britain needed a fast communication link with the USA and the Telegraph
Construction and Maintenance Company was formed in April 1864 to take up
this challenge. Brunel’s friend and colleague, Daniel Gooch was one
of the company’s directors. He formed a syndicate that purchased the
Great Eastern, the only vessel capable of carrying the immense length of
cable that was required, for £25,000. He then offered the ship to
the company free of charge on the understanding that if the venture was
successful the syndicate would receive £50,000 in Atlantic Telegraph
stock.

The ship set out from Ireland in July 1865. On 2 August, 600 miles from
Newfoundland, the cable end was lost overboard and the attempt abandoned.
A new company was formed at the suggestion of Gooch – the Anglo-American
Telegraph Company – and a fresh attempt with an improved cable began,
reaching Newfoundland on July 27 1866. Gooch wrote in his diary:
We have achieved our great object and laid our cable from shore to shore,
along which the lightning may now flash messages of peace and goodwill between
two kindred nations. Is it wrong that I should have felt as though my heart
would burst when that end of our long line touched the shore amid the booming
of cannon, the wild half-mad cheers and shouts of men? It seemed more than
I could bear.
John Gordon Steele, in his account of the cable laying wrote:
It is by no means the least of her ironies that the one thing the Great
Eastern turned out to be good for – indeed perfect for – was
perhaps the only use her creator had not foreseen from the beginning.
