Marconi Selenia Marine have fitted the VSAT high speed data system on board the Trinity House lighthouse tender THVMermaid and will provide the service with all the advantages and facilities of land based broadband services at a fixed monthly cost. The installation has been so successful that Trinity House has placed an order for a similar system to be fitted on sister tender THV Patricia .The THV Mermaid is already fitted with Marconi Selenia Marine supported satellite communications equipment supplied by the company's Lowestoft UK office. The installation of the VSAT system is a continuation of the ongoing expansion of a computer networking system developed through close co-operation.
