MetOcean Station System Network

For Safety for Offshore Marine & Aviation Operations

A reliable and accurate metocean station is not only critical to the safety of marine and aviation operations, but also important in enhancing the efficiency and effectiveness of offshore operations, which results in significant savings in offshore operating cost.

A reliable and accurate meteorological and oceanographic monitoring station (Metocean Station) is vital to the safety of offshore marine and aviation operations. A metocean station installed onboard an offshore platform provides, in real-time, to operators ambient weather information, such as wind speed, wave height, and ocean current, which are critical to helicopter landing, vessel approaching the platform, and diving operations.

COMPATIBILITY

MOSSNet meets the requirements recommended in the Standards for Offshore Helicopter Landing Areas, CAP 437.

It is capable of not only monitoring the local metocean conditions, but also making the measurements available across the IT network in real-time, so that users in a remote office have access to the weather data. All that is required is a common web browser which is readily available on almost all PCs and handheld devices, such as tablets and mobile phones.

SYSTEM

  • Display of all meteorological and oceanographic parameters in real-time locally and remotely
  • No special software needed for viewing the collected data
  • Archive of measured data
  • Display of archived data locally and remotely
  • Transmit data through LAN and WAN
  • Calculation of the required parameters;
  • Quality control of measured data
  • Remote control through LAN and WAN
  • Display of warnings at selected thresholds for different types of operations
  • Expandable to integrate additional sensors and functionalities
  • Auto-start after power is on
  • Link to platform’s DCS

CENTRAL STATION NETWORK

Multiple metocean stations installed offshore can be linked to a central station. The central station gathers the data collected by all the offshore metocean stations and disseminates specific data to specific users via email, e.g. weather data sent to weather forecasters for them to improve accuracy of the forecasts..

SYSTEM TYPES

MOSSNET is flexible and can be customized to meet users' requirements. Standardized metocean stations are also available for speedy delivery and (AT) minimized costs. Based on our many years of experience in the offshore industries, three standardized metocean stations are available.

  • Met Station
  • Ocean Station
  • Metocean Station

  • Met Station

    Met Station is configured for the purpose of application where waves and ocean currents are of minimal concern, such as at an airport, shipyards, or well-sheltered water. Comprises only of meteorological sensors, its designed to be informative yet cost effective in its objective. The Met Station includes anemometer, barometric pressure sensor, temperature and humidity sensor (a visibility sensor and a ceilometer can be included for supporting aviation operations).

    This configuration is meant to be of simple use with the setting up and commissioning requiring no more than two man-days. Regular maintenance cycle of once per annum is recommended, and the station normal working operation should be up to 10 years. The coverage area should be applicable for a radius of up to 50 km in an unblocked area.

  • Ocean Station

    Some vessels/platforms have a meteorological station already installed at build but no oceanographic sensors. A standalone oceanographic station will be needed when the vessels/platforms are operating in an environment with high waves or strong currents. An Ocean Station will be comprised of a sea state sensor that monitors surface waves and currents.

    Ocean Station is configured for concern or a meteorological station has drilling rig or a FPSO, or even a survey and fit for purpose with different sensors includes an Acoustic Doppler Current and surface waves. The station is requires less than 2 man-days. The months. The measured waves are in an open sea while the ocean currents dependent phenomenon. The life span conditions.

    Applications where only the sea state is of already been installed, such as those in oil vessel. The station is designed to be mobile to choose from. A standard Ocean Station Profiler (ADCP) for measuring ocean currents uncomplicated for setting up and usually maintenance intervals are recommended at 3 representative for a radius of 30 nautical miles are much more localized and a topography of the system is up to 5 years under normal

  • Metocean Station

    A Metocean Station is designed to fully support marine and aviation operations. It is usually installed onboard a fixed platform or a floating production vessel equipped with helipad. The Metocean Station is designed to meet the recommendations of CAP437.

    It collects all the essential parameters required by marine operators and helicopter pilots. It includes an anemometer, barometric pressure sensor, temperature and humidity sensor, visibility sensor, ceilometer, and sea state sensor. Setting up and commission may take 5 man-days. The sea state sensors need to be maintained every 3 months while other sensors are recommended at least once a year. The Metocean Station can last up to 10 years under normal conditions.

    There may be other sensors which can be integrated into the metocean system if required, such as:

    • CCTV system for monitoring the helideck and activities around the platform;
    • motion sensor which is required for the helideck on a floating structure, e.g. a FPSO;
    • rain gauge and a solar radiation sensor
