Refurbishing the tilting
gate at Scotstoun
KGAL has been commissioned by Arch
Henderson on behalf of BAE Systems to provide
technical support and site inspections for the
refurbishment work being carried out on the
30m wide x 12m high tilting gate used on dry
dock number 3 at BAE’s site at Scotstoun, at the
heart of Glasgow’s shipbuilding heritage.
The work is currently being undertaken by a specialist contractor in
accordance with the mechanical, hydraulic and electrical works
specification produced by KGAL in 2023, following a thorough gate and
operating gear site inspection.
The refurbishment includes the redesign and installation of the hydraulic
gate latch operating equipment, refurbishment of the wire rope
operating drum and winch motor, refurbishment of the wire rope
sheaves, axles and replacement of the wire rope. The electrical controls
are also being updated and will include wireless pendant controllers for
local gate operation.

Launch Lock, Teddington Lock, London
KGAL has been commissioned by Jacobs, on behalf of the Environment Agency, initially to carry
out investigation work to determine the reasons for various mechanical failures on the head and tail
mitre gates located in Launch Lock, Teddington Lock, London.
Teddington Lock is the first lock encountered on the River Thames from the
City of London and is a complex arrangement of locks and weirs. It is the highest
tidal point on the River Thames, and the point at which the control of the rivers
passes from the Port of London Authority to the Thames River Authority.
The preliminary investigation has led on to KGAL detailing various
modifications and refurbishment requirements to the gate structures, the
detailed design of modified top anchor arrangements, the revised location
and design of new gimbal mounted hydraulic cylinders, and the detailed
design of new pintles and stainless steel quoins.
The construction and installation of stainless steel quoins is dependent on
forthcoming dewatered lock investigations of the existing stone quoins. The
KGAL design also includes the outline design of all the associated electrical
and hydraulic components, such as PLCs, operating pedestals and hydraulic
power units (HPUs) with associated pipework and components.
The design work has been carried out to a tight deadline in order to ensure
that the lock is back in operation in 2025.
