The Large Automated Navigational Buoy or LANBY was introduced around Great Britain and Ireland in the early 1970’s. They were seen as a cheaper way (and one not requiring keepers) of providing a beacon at sites traditionally occupied by moored lightships. LANBY’s were fully automatic, powered by triple-redundant diesel generators and capable of running on station without attention for months. The buoy was about 14m/40′ across and carried its light about 14m/40′ above sea level.
In operation, LANBY’s were not particularly successful but filled a useful gap between the need to phase out lightships and the introduction of reliable solar-powered buoys. The last LANBY (on the Coldling station off Wicklow, Ireland) was withdrawn and scrapped in 2010.
