Since Wartsila’s involvement with the Lerwick Port Authority, VTMS operations have reached new levels of reliability and accuracy. User experience has been improved greatly from the previous system.

System upgrade is planned for 2021 to replace all the IT infrastructure with version 4.6, and radar processor upgrade using RPU5 interfaces. Wartsila continues to provide service and support to the Lerwick Port Authority with an annual maintenance contract including Remote System Support, Service Portal Access, Weekly system checks and Account Management.

We are a very strategic location for oil and gas production in the North Sea, handling many construction and supply vessels servicing existing and new fields. Keeping operations up and running during the pandemic has been of paramount importance.
