MS Guardian

On 22 June 2012, Javelin International presented Guardian, a multifunctional and exceptionally seaworthy commercial vessel of the Javelin 22.22 type. Guardian was built by KD Workboats in Urk and is specifically designed for crew tendering, hydrographical & seismological research and survey activities. Piet Brouwer Electrotechnology designed and installed the entire electrical system. Guardian is the world’s first commercial vessel equipped with a gyro-stabilising system that is designed by the American company Seakeeper and commonly used in superyachts. Javelin International developed the Javelin 22.22 in close cooperation with KD Workboats and design & engineering company Vripack.

Guardian also comes equipped with a Marble system, consisting of an alarm and a monitoring & control system that allows the alarms and values of the engines to be read via the Modbus RS 232 protocol. As the system also reads the alarms and values of the engine via the Ethernet, all essential items can be seen on the touchscreen, offering a precise overview of its condition. The Marble system also shows tank measurements, while two 15” Marble touchscreens indicate the pumps, ventilators and moon pool (used to perform hydrographical measurements), lighting and navigation lights. An electrical page shows the generators and the connection to shore power and batteries.
