Vaisala Maritime Observation System MAWS410

www.vaisala.com

The Vaisala Maritime Observation System MAWS410 is an automatic weather station especially designed for maritime applications such as ports, ships and off-shore platforms. The MAWS410 is easy to install, and can be implemented quickly. It can withstand the salty and wet conditions that prevail aboard ships and platforms, and it also tolerates freeze and thaw conditions in extreme-weather environments. It is also endures vibration and shock.

Measurement parameters

The basic weather parameters measured are wind speed and

direction (relative wind, true wind, upwind), atmospheric pressure (QFF, QFE, QNH, pressure trends), air temperature, and humidity (dew point). The sensors are typically installed on a tiltable 3-meter mast. The mast can be easily be tilted for installation or maintenance. Additional sensors for measuring other parameters, such as sea water temperature, duration of rain and sunshine, global and long wave radiation, amount of precipitation, and cloud ceiling and visibility, can be installed as well.

Accurate true wind calculation

For the most accurate true wind calculation, the vessel’s own gyro compass and navigation system is used providing the required heading and ship speed, direction and location information. All the requirements for data communication given in NMEA 0183 and IEC 1162-1 are fully supported. A GPS receiver, Inmarsat- C satellite transceiver and GPS compass are also available. No matter what communication systems you use, the MAWS410 supports them – both external and onboard.

Built-in data validation

Built-in algorithms test each measurement to ensure data quality. For every parameter, tests are carried out on the minimum and maximum readings, step limits, and the various parameters are cross-checked. When data is entered manually, quality checks ensure that the operator does not enter incorrect values.

A built-in testing system continuously checks the sensors, reporting immediately if a fault occurs. An expansion memory for data storage is also available if not sent to an

Advanced ship weather reports

The system processes, displays, stores and transmits fully automated ship weather reports in the universal FM 13 SHIP (FM 13 XII) and IMMT-3 code formats around the globe in real time. These reports can be augmented with visual observations entered prior to transmission. Factors such as cloud type, past weather, weather phenomena, waves and swell, as well as sea-ice and/or ice accretion onboard are added by using Vaisala Observation Console software.
