The decommissioning and removal of a weather station from Sule Skerry.
LARS Communications has recently completed the decommissioning and removal of a weather station from the remote island of Sule Skerry.
Sule Skerry is a remote skerry in the north Atlantic, thirty-fives miles to the west of Orkney’s mainland (a skerry is a small, rocky island generally considered too small for human habitation).
The island is approximately forty acres in area and about half a mile in length. It is listed as a special protection area as it is home to thousands of puffins, gannets, shags, petrels and seals.
To dismantle and remove the decommissioned weather station from the island, transporting it to a skip on the mainland. The weather station comprises a tower and a cabin, as well as a range of temporary equipment items.

This operation required sensitivity, extensive logistical planning and collaboration with a number of third parties, including local residents and businesses.
In collaboration with PDG Aviation, LARS successfully completed the dismantling and removal of the weather station. The companies had to work within a very small window of opportunity due to the breeding seasons for the seabirds. Consulting with the relevant wildlife associations and charities, LARS was able to remove the structure with minimum disruption to the island’s wildlife.
