Greenwich Lightvessel
Greenwich is a lightvessel station in the English Channel, off the coast of East Sussex. It is operated by Trinity House. It is one of the 22 coastal weather stations whose conditions are reported in the BBC Shipping Forecast but was dropped from broadcasts some time during 2019, before being reinstated. The name of the station derives from the fact that is located close to the Greenwich Meridian.
The vessel currently on this station is the solar powered Trinity House Lightvessel No. 5, built in 1946 and in active service at various stations around the British coast since 1947.
Origins and stationing
The Greenwich station was established during the 19th century, a time when shipping traffic in and out of the Port of London was at its peak. The complexity of the Thames Estuary, with its shifting sands, narrow approaches, and strong tidal flows, made fixed lighthouses impractical in certain areas. As a solution, floating lightships such as the Greenwich Lightvessel were moored to provide reliable navigation aids.Design features
The vessel is painted in a distinctive red with the word "GREENWICH" displayed in bold white letters along its hull, in accordance with Trinity House standards for lightvessels. A lantern tower sits on the deck, equipped with modern optical technology that provides a bright and consistent light visible in various weather conditions.The structure of the hull is engineered to provide stability while moored in open waters. It uses robust anchoring systems to remain secure even in adverse weather. Earlier versions of the Greenwich lightvessel employed oil lamps and fog bells, but modern adaptations now rely on electric beacons and automated fog signals.
