The first ServoTrim system will be delivered to a Taiwanese shipyard for integration with a 22m wind farm supply vessel under construction for a UK-based operator.
Wayne Ross, Chief Executive Officer, Servowatch, said: “The need to calculate ship trim and draught is one of the most important measurements operators take to ensure vessel stability and safety. ServoTrim is designed to control a balanced draught for a vessel, providing automatic flow control after manual trim has been set.

“While the system is not a fully automatic dynamic stabilisation system, the system can be reset to automatically recognise the optimum trim and draught for different operational conditions, such as loading or unloading fuel, supplies and personnel.”
The ServoTrim installation for the SWATH wind farm supply vessel has been designed specifically for a four ballast tank configuration, with each tank fitted with a single sensor to provide concurrent tank, pump and valve status monitoring. Draught sensors are sited at each ‘corner’ of the vessel.
“Other types of vessels can benefit from ServoTrim,” said Servowatch Systems’ Sales Director Martyn Dickinson. “It can be easily applied to inland waterway barges and heavy lift platforms. Certainly situations may exist where the platform needs a dedicated system which can provide a draught and trim correction function to counter uneven weight distribution.”
ServoTrim employs high-accuracy hydrostatic level transmitters to measure ballast tank levels and provide multi-port draught indications. To protect the sensors from external moisture, they are encased in IP68 and IP69K standard stainless steel housing.
