The Port of Dover has signed a Contract Agreement with a Finnish company; VRT Finland Ltd. This contract builds upon the co-operation between the two companies. Effective immediately, the two year contract covers the delivery of underwater inspections between 2018 and 2021 for the entire 3.45km2 port area, the first part of the contract has already commenced with field work being undertaken in May 2018. Underwater inspections by VRT are a part of the Port of Dover’s asset management program as the processed and interpreted 3D data significantly facilitates construction and maintenance planning, preventing any costly surprises in future repair activities. Handling £122bn or 17% of the UK’s trade in goods, it is important that the Port ensures safe marine operations and the ongoing long life cycle of structures. The Port of Dover has a wide range of assets of varying structure types, situated in the coastal marine environment, these require inspection, testing, assessment and maintenance as part of the Port’s developing and ongoing long-term asset management plan. “VRT’s inspections allow us to monitor any long-term trends in the deformation characteristics of the structures, the early identification of any potential issues allows the Port to undertake suitable maintenance or remedial designs if necessary," says Darren Bell, Geospatial Engineer at Port of Dover. The co-operation started two years ago, when VRT Finland; specialising in multibeam sonar technology and 3D data management, surveyed over 5km of marine structures in works spanning 2016 and 2017. The projects provided the Port of Dover with post-processed and analysed point cloud data as well as detailed 3D and 2D CAD models. As a result of the new contract agreement, it is the intention that every principle marine structure is surveyed over the next 4 years. Some of the structures will be inspected for the first time to collect baseline data for future surveys while a part of the port’s infrastructure is surveyed already for the second time, which enables detailed change comparisons between data sets. “The framework agreement is a great opportunity to carry out inspections for the whole port area to collect important baseline information to enable long-term monitoring of underwater structures. "With multibeam sonar technology, we can make the invisible underwater structures visible while also surveying the structures above the surface with laser scan. With our underwater inspection service and VRT BIM online service, Port of Dover can digitize assets for smart asset management”, explains Karri Koistinen, Client Executive at VRT Finland.
