Walney Island harsh-environment casing

They are committed to problem solving – they used their knowledge to great effect coming up with a protective unit for our kit when it started to corrode. Met Engineering stands out as the best service – I have no need to look at any of the others.


BAE Systems, the world’s second largest defence and security company employs around 100,000 people worldwide. The company delivers a full range of products and services for air, land and naval forces, as well as advanced electronics, security, information technology solutions and support services.BAE Systems (Marine) Ltd owns and operates the airfield on Walney Island, near Barrow-in-Furness, UK.


The geography of the Walney Island site determines that the airfield is subject to almost incessant, moist, salt-laden winds sweeping in from the Irish Sea.The result of this persistent attack by the elements is serious corrosion of the various vital navigational and meteorological aids and systems.MetEngUK have provided BAE Systems with meteorological equipment and engineering support services for more than a decade, and were asked to find a permanent solution to the corrosion problem.


High quality die-cast aluminium alloy boxes are used to contain the data transmitters for the airfield wind system and for the temperature/humidity system. In addition to providing rigid mechanical protection, these boxes act as effective electrical screening, and must be retained. MetEngUK’s answer was to identify suitable, weatherproof ABS housings that would accommodate the die-cast boxes, cater for all cable connections, and allow ready access for servicing purposes. The data connectors serving the individual wind sensors were fitted with protective PVC shrouds.These ‘HE’ (harsh environment) kits have now been fitted to meteorological systems at numerous coastal airports, heliports and airfields to significantly extend equipment life and reliability, as well as providing user cost savings.
