Lay Lines 2018

Lay Lines

The art installation, Lay Lines, by artist Bobby Lloyd, stands in a location that has been associated with the manufacture of submarine cable systems since 1857. Back then the 14 acres (5.66 hectares) of the factory site stretched from Enderby Wharf, on the river front, across to Blackwall Lane (then Marsh Lane). The gantry and cable hauler on the wharf date from the mid-1950s and were used to pull the cables out of the factory to load them on to ships, moored in the River Thames.

In 2008, Alcatel Submarine Systems (ASN) sold the river frontage, allowing the current housing development to take place. ASN is the world’s leading supplier of submarine cable systems and still manufactures elements of its systems on the remainder of the site, now accessed from Telcon Way.

On the opposite wall to the QR Tag are three ceramic panels, which show the greatly magnified detailed cross-sectional images of three different cable designs. These represent the three eras of submarine system transmission technology:

1850-1950 – The Telegraph Era

1950-1986 – The Telephone Era

1986-Today – The Optical Fibre Era

In addition, the Lay Lines art installation comprises three sculptures inspired by these cable designs. More information on this art installation can be found on Bobby Lloyd’s website (https://bobby-lloyd.format.com/lay-lines).

The Telegraph Era

The left-hand panel of the three shows a cross-section of the first submarine telegraph cable manufactured on the Enderby Wharf site, which was used in an unsuccessful attempt to lay a cable across the Atlantic in 1857. More cable of this design was made in 1858, and after another failure, a third attempt that year was finally (although only temporarily) successful. This cable design is the inspiration for the sculpture on the lower of three terraces.

The Telephone Era

The centre panel shows a cross-section of an armoured version of the STC 1.47” coaxial cable, the most successful submarine telephone cable design of the Telephone Era. STC Submarine Systems owned the Enderby Wharf site from 1970 to 1996 and this cable was manufactured there between 1970 and 1975. This cable design is the inspiration for the sculpture on the middle terrace.

The Optical Fibre Era

The right-hand panel shows a cross-section of the ASN fibre optic cable type, OACL-4, the company’s current design of fibre optical cable for transoceanic subsea telecommunication. The cable type shown is known as Lightweight (LW) cable and is deployed in water depths from 2,000m down to 8,000m.

Today submarine cable systems carry terabits/petabits of data beneath the oceans. They are the arteries of the internet, enabling e-commerce and shaping social media, so submarine cables are arguably the most important technology in modern society.

ASN manufactures this cable in its Calais factory. However, the repeaters that boost the optical signal, the power feeding equipment, and the optical transmission equipment are all made here in Greenwich. This ASN factory has been manufacturing submarine cable systems for longer than any other site in the world. This cable design is the inspiration for the sculpture on the upper terrace.
