MM Engineering has recently undertaken a number of flood gate installations for a distribution network operator in Scotland Aberdeenshire. The local area and the utility assets were inundated with flood water during the December 2015 flood event along the River Dee. This also caused the whole towns power to cut off during the floods for several days. As well as needing flood protection, access to the transformer bund needs to be maintained as site engineers’ visit on a regular basis as part of their routine maintenance.
The existing 11kv transformer security fencing was removed by the civil contractor and a new Hollow concrete block flood wall with steel reinforcement and concrete infill was constructed.
We were approached to design, manufacture and install a number of single flood gates. These were to be operable by one engineer and capable of withstanding a 2 metre hydrostatic load. MM Engineering achieved this by machining well balanced bespoke hinges and two bespoke locking handles from grade 304 stainless steel. The MM Engineering flood defence gates were secondary fixed using Hilti fixings and specified anchor resins. Transformers are filled with insulating oil to keep them cool and our flood seals are wrapped in Nitrile rubber to protect them for any potential oil leaks.
The schemes are now protecting the local 11kv transformer supply points from future flooding events along the River Dee in Scotland. As the transformers are now surrounded by solid bunds and flood gates it’s also protecting the environment from any potential oil leaks.
