AEMT Visits The Scottish Canal’s Falkirk Wheel or the Scotland meeting this year, AEMT members were able to gain an exclusive audience with the Principal M&E Engineer for the Falkirk wheel. After being guided through the more technical aspects of the engineering behind the wheel and the connected canals, members were taken on a tour of the wheel's engine and maintenance rooms. F Steven Berry B.Sc MIET is a contented, and enthusiastic person, whose passion for engineering is infectious. His occupation takes him up and down the Scottish canals, looking after the mechanical and electrical aspects – in particular the Falkirk Wheel, Kelpies, and Helix Park. Much of the work includes power and control systems, mechanical and hydraulic upgrades, and energy saving equipment. It's clear that he takes great pride in the work he does for Scottish canals. With the Falkirk Wheel being the central aspect of an £85 million re-investment in the Scotland's inland waterways – he has quite a lot to be proud of. The canals are dominantly a tourist attraction these days, a far cry from the toil they received at the 80 PECM Issue 28 turn of the century. With around 400,000 visitors a year, it brings a crowd – and what a brilliant location to show off the engineering capabilities of Great Britain. T he W heel Opened in 2002 as part of the Millennium Link, a project that restored Scotland's inland waterways to a navigable state for the first time since the 1960s The Wheel replaced a flight of 11 locks that once stepped the Union Canal down to the level of the Forth & Clyde over a distance of 1.5 kilometres and took more than a day to traverse. The Falkirk Wheel allows vessels to transit between the two waterways in just a few minutes. While touring around the wheel in hard-hats and high-vis, members were approached by a keen member of the public, who presumably thought that we were the most reliable source for information on the wheel. In order to settle a wager with his partner he asked us to clarify the reason for the wheel's unique design. Steven proudly deferred the question to us, after briefing us beforehand on the subject. The unusual design of The Falkirk Wheel has been described using Scottish and marine architectural terms including a Celtic inspired double-headed axe, the spine of a fish, ribcage of a whale and the vast turning propellers of a Clydebank- built ship, so to answer the man's question - aesthetics. Unfortunately, this was not the answer he was looking for – like most people he was sure there was some sort of an aerodynamic/engineering answer to the wings and he turned about with the skip from his step slightly down trodden. A rchimedes P rincipal If a 200-tonne vessel approached the Wheel, glided onto a gondola and waited a few minutes for the wheel to effortlessly lift the 500 tonne gondola and vessel 35 metres, using only 1.5kw/h, you might question the principals behind the structure. It took a combined effort between the British Waterways Board, and engineering consultants Arup, Butterley Engineering and RMJM to come up with the final design. The solution: when one of the structure's gondolas is lowered, the opposite one rises, keeping the vast 1800
