Project Title | CuGuard™
Client | Babcock / MoD
Project Value | £ classified
Chemical | Ferrous Sulphate
Duration | 12 weeks
Design and build self-contained portable ferrous sulphate dosing systems for seawater cooling system protection for use on warships and submarines.
The equipment is designed to comply with Ministry of Defence Standard 02-781 Protection of Seawater Systems Pipework and Heat Exchanger Tubes in HM Ships and Submarines and includes facilities to:
- Prepare an accurately proportioned solution of technical grade ferrous sulphate granules in water using a saturator assembly.
- Provide a dosing system capable of working in either a pipe passivation mode (burning-in) or in film maintenance mode.
The new units incorporate a digital “stepper motor” diaphragm dosing pump, laser level sensing and electromagnetic flow sensing all operating under PLC control via a custom-designed HMI interface and mounted in a compact and robust wheeled assembly designed to be moved easily in the tight confines of a warship.
