Helideck Standards CAP437

The SMC Helideck Monitoring System is as flexible as many of today’s offshore vessels. Current industry requirements may require that a vessel works in various locations around the globe. Being able to meet all of the required Code and standards applicable in different regions is of critical importance.

The SMC HMS meets all of the following standards:

SMC Helideck Monitoring System

System Layout

The System visualizes the instrument data in an easy to read HMS interface. The Data is logged in a database and can be viewed in the system log view. The SMC software can be used as a stand-alone system on a single PC or across a network with the multi-user client, or viewed in standard browser. The SMC Helideck Monitoring System is designed with all the criteria of the current international code requirements for helideck operations in an offshore environment.

The SMChms provides motion and meteorological information in a clear and comprehensive graphical interface.


A standard for HMS Systems usually requires but is not limited to the following motion and meteorological instruments:

  • MRU Motion Reference Unit
  • Wind Speed & Direction
  • Air Pressure Sensor, two pressure elements for verification purposes
  • Temperature and Humidity sensor
  • Ceilometer
  • Visibility & Present Weather
  • Gyro Compass
  • GPS
  • Helideck Repeater Lights

Typically, the type of vessel and operational areas will determine the list of instruments required. Fixed installations, Semi Submersibles, crane and lay barges, FSU’s, large ships, drill ships, FPSO’s and jack up rigs all are required to have the full list of instruments.

Data Log

All system instrument data is logged into an SQL database. The built in system Log view gives the user the option to select data and parameters from the system SQL database and display the data in graphical charts. Several charts with different settings can be created by the user in each Log View module. Data can be exported into csv files for analysis in different third party software.

System Security

The SMC Monitoring System uses an Access Control List (ACL) security feature. This feature enables the system to have any number of users and each user can be a member of multiple roles with a selected set of permissions to limit the access to the system configuration.

System Alarms

The Alarm function in the SMC system provides the user to configure thresholds to trigger actions once the parameters form the devises exceeds the set values. Example of actions available is to change a Voltage-Free Contact, send an email to selected users or display a note in a selected module interface.

Third-Party Data Output

The SMChms software offers multiple options for Data output communications connecting to Third-Party external systems supplying data from the Motion sensors and Weather instruments over for example SNMP, Modbus TCP/RTU, TCP/UDP, Helimet, WITSML and Serial ASCII protocols.

Met-Ocean System

Together with SMC's unique modular software solution that provides a flexibility of additional environmental instruments and custom displays. The display modules can be used by different operational teams with one server software solution.

Voltage Free Contacts, Relays

With the installation of an optional Voltage Free Contacts device to the HMS server PC a dry voltage output signal can be generated for use to switch Helideck Lights and other alarm outputs. Relay inputs can be read from Third-Party system for various actions within the SMC system.
