The Large Automated Navigational Buoy or LANBY was first introduced in the USA in the early 1970’s and used initially for weather monitoring or scientific research. They were quickly investigated 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. Thy were typically about 14m/40′ across and carried their 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.
This prototype LANBY was designed in Germany but never built – and the lessons learned helped with the design of the relatively small number of LANBY’s actually deployed in German waters.
