A NEW £600,000 vessel has joined the survey fleet of Associated British Ports (ABP)’ Humber Estuary Services.
The Humber Surveyor has been built by Blyth Catamarans, in Essex, and was delivered early this June.
The vessel’s equipment includes a £200,000 multibeam sonar, two single beam sonars, side scan and forward scan sonar. It is capable of three dimensial mapping of the ever-shifting sediment within the Humber Estuary.
The vessel is also able to digitally model marine structures such as quaysides, buildings bridges and shorelines, using a lasr scanner mounted to the roof.
The Humber Surveyor is complemented by the rigid-hull inflatable boat Humber Scout which can be lifted on board larger vessels and delivered to a site.
The Humber Scout is the smallest coded multibeam-capable vessel in the UK. Her size and manoeuvrability enable Humber Estuary Services to survey areas as far upstream as Gainsborough, where the River Trent can be too shallow for a larger vessel. By using the Humber Scout in this area, a survey can be completed in just two days.
ABP said: “The Humber Estuary drains one fifth of the area of England and the movement of channels within the Estuary is a continuous process.
“Each year, Humber Estuary Services undertakes over 600 individual surveys and due to the rapidly changing river bed, some surveys need to be completed on a weekly or fortnightly bases.
“The resulting survey charts are then distributed and annually more than 5,000 copies are made freely-available to all river users.
“The information displayed on the charts is fundamental to the safe movement of over 33,000 vessels on the Humber Eatuary every year.”
