Retained by Coode & Partners as the sub-consultant gate design specialist for the rehabilitation of the 43 No18.29m span x 6.4m deep barrage gates originally installed in 1948 by Ransomes and Rapier Co. Ltd. The barrage gates were "stoney" roller type with rocking roller paths on the embedded parts, all of which were badly worn and corroded. The scope included review/approval of the replacement gate structures, re-design, upgrading and the manufacture of the replacement "stoney" rollers and roller paths, using modern abrasion resistant materials.
Hartlepool Marina Lock Sector Gates, UK - Kvaerner Boving Ltd
Design responsibility for the two pair of lock sector gates 9m span x 8.5m deep, including the development of fully adjustable dual direction sealing arrangements. The gates were fast operation type designed to open or close in 30 seconds, using hydraulic cylinders and independent power units.
Garstang Flood Control, UK - Boving Newton Chambers
Failure of the original 2 No 8m x 4m fishbelly flap gates and the hydraulic cylinders manufactured by an inexperienced gate supplier, prompted North West Water to seek help from BNC. My review of the design of the original gates, pivots and cylinder sizes showed inadequate pivot/anchor design for the one-sided lift application, causing overloading and failure of the anchors and concrete cracking at the pivots. I also noted undersized cylinder rods, which culminated in the rod deformation. Rectification was identified as upgrading the gate pivots, adding more pre-tensioned anchors to suit the applied loads and the supply of new cylinders with larger rod diameter, designed to prevent buckling at the hydraulic system relief settings.
Sydney A Murray Power Station, Downstream Control Gates, USA - Boving Newton Chambers
I was assigned the design responsibility for 8 No 10m square wheeled draft tube gates with fast acting operation to protect the turbine from runaway and to act as maintenance bulkheads. Each gate weighed 120 tonne and as defined by the turbine hydraulic model tests were to be designed for fast gravity closure at 40m/min, using a single acting hydraulic cylinder developed specially by Hunger Ltd. The gates were designed to withstand hydraulic transients 50% in excess of the static heads, caused by the close proximity of the gate to the turbine axis and the pumping effect of the turbine during retardation.
River Foss Flood Gate, York - Boving Newton Chambers
The 8.5m span x 8.2m deep floodgate was required to reduce flooding of the River Ouse from the Foss at York. The contract was awarded by Yorkshire Water Authority for the design of an "up and over" flood gate similar in design to the nearby Hull Barrier gate, but smaller in scale and in this application a slide type gate was selected.
MRICA HEPP Spillway Radial Gates, Indonesia - Boving Newton Chambers
I was responsible for the design and project managment of four 14.25m span x 12m deep x 14m head Spillway Radial Gates. The role included design calculations including FEA modelling and seismic analysis, overseeing detail drawings, procurement specifications and training. The gates are operated by two 120 tonne capacity hydraulic cylinders.
Naval Base Dock Entrance Flap Gate, Sultanate of Oman - Boving Newton Chambers
I was assigned the full design responsibility for the 22m span x 12m deep x 160 tonne floating dock basin entrance gate, including two months site responsibility during installation for the floating, stepping and un-stepping procedure of the gate. Although the initial procedure included full training of operatives I have repeated the un-stepping and stepping procedure at two later maintenance outages for damage repairs due to a rope failure and the periodic re-painting of the gate in this aggressive marine environment. The gate floats horizontally for positioning above the pivots, and then using compressed air filled buoyancy chambers tilts unaided to the vertical position, and lowers into the pivots in a controlled manner. The gate is normally opened and closed using a 130 tonne capacity hydraulic motor operated winch unit incorporating 52mm dia wire ropes reeved thro' sheaves at the gate top.
Glen Park Hydro, USA - Boving Newton Chambers
Glen Park Hydro Electric Development placed the order for the design and supply of 4 No 4.8m span x 3.35m deep x 25m head bonneted draft tube wheel gates and 4 No 3.25m span x 12.64m deep floating intake bulkheads. My responsibility included the detail design calculations and review/approval of the detail drawings for the draft tube gates on this project.
Canoe Slalom Inlet Control Gate, Nottingham - Boving Newton Chambers
Development of the Sales and Contract design of this unique 5m span x 2.77m deep canoe slalom inlet control gate for Nottingham City Council at their Holme Pierrepoint International Water Sports Centre. The design allowed canoe paddlers to safely pass over the gate and also to adjust the in-flow to produce differing white water conditions on the course downstream. The gate was developed from a torsion tube type gate leaf with a downstream sloping apron, all operated by one hydraulic cylinder in the sidewall chamber.
Barking Barrier - Boving Newton Chambers
Barking Barrier forms part of the Thames Barrier for the closure of the Barking Creek tributary. I was responsible for the conceptual design of the 4 barrage gates and the hoists, including cost estimation and review of the contract design to ensure specification compliance. The main gate was the largest gate vertical lift roller gate reference in the Newton Chambers Eng. Ltd portfolio at 38.6m span x 10.8m deep and total weight of 300 tonne. Design features were developed for the chain hoist to allow gravity closure under loss of AC power, included "quick release" latches activated under gate net dead load, 50% counterweighted and hydraulic motor retarding system. Operational redundancy and safety was built-in using cross shafts, duplicate electric motor drives and output disc braking systems.
Hull Barrier - Boving Newton Chambers
In 1978 I was responsible for the conceptual design, cost estimate and overseeing the contract design of the 200 tonne 30m span x 10.6m deep "up and over" flood protection roller gate for the Yorkshire Water Authority, including review of the chain hoist designs to fit the tight architecturally designed counterweight towers. The gate was installed at the fully open position, 22.6m above the river Hull. My responsibility also included the development of the guidance features to allow lifting the gate vertically and turning thro' 90 deg to finish open in the horizontal position, thus allowing more headroom for the passage of vessels.
Velocity Control Fishbelly Flap Gate, Ipswich - Boving Newton Chambers
My responsibility in 1978 included the Sales conceptual design and costing of the UK's first modern long span fishbelly flap gate. The gate function was to close on an upstream signal to reduce the velocity of the floodwater and prevent downstream riverbank erosion on the River Gipping at Ipswich. The client was Anglian Water Authority. The gate was 33m span x 4.5m deep and designed torsionally rigid to allow operation using a single hydraulic cylinder. This design eliminated the use of two hydraulic cylinders and the associated synchronisation problems, and prompted future similar designs for use on a number of dock and harbour installations.
