The Scottish Ministers, Marine Directorate invites tenders for the purchase and installation of replacement for the underwater components of a Teledyne Reson T50 multibeam system. The Teledyne Reson T50 is a shallow water, multi-frequency, high resolution, true beam forming, multibeam echosounder system (MBES). The components will replace those lost while on the hull of the marine research vessel, MRV Alba Na Mara. The tender is for supply and installation of the hull mounted components and associated internal cabling only. Peripherals such as T50 processor, IMU/GNSS navigation and motion reference systems are already fitted to the vessel and do not form part of the tender invitation. Installation of the MBES components will take place during the annual dry docking of the vessel. This is expected to take place in early spring 2027 at a UK shipyard to be decided by open tender.
