SMC Helideck Operation System for Yachts, HOSY, offers a pre-configured and easy to install system to comply with Large Yachts and other vessels that have a Helideck. Vessels that do not require the full CAP437 HMS system still require a monitoring and display system, in line with the codes such as the MCA Large Yacht Code LY3 and others such as the Red Ensign Yacht Code.

The SMC HOSY is a combination of the SMC VMMS, Vessel Motion Monitoring System and Weather interface on one single SMC-1310 Panel Display. These two software tabs on the user-friendly touch screen panel display provide real-time data from the connected Motion Reference Unit and Weather Station to provide an overview of the Helidecks landing conditions.

Display and Interface

The panel display a high resolution and high brightness 10.1” Linux industrial touch screen panel PC, complemented by brightness control to enhance the viewing experience. Three themes are available classic, oceanic and amber shade, adapting the color themes to different times of the day optimizes user experience. A light theme with bright colors suits daylight, reducing eye strain. In the evening, a dark theme minimizes glare and enhances focus.

Yacht system requirements

For Large Yacht operations details of pitch, roll and heave motions need to be recorded prior to Helicopter operations for a 10 min period as well as weather data Wind Speed, Direction, air temperature and barometric pressure from automatic read instruments. This data needs to be displayed to enable safe operations and recorded. All the mentioned elements are encompassed within the HOSY, ensuring that all necessary yacht requirements are fulfilled through a straightforward installation.

System Layout

The System visualizes the instrument data in an easy-to-read interface. The SMC software can be used as a stand-alone system on a single PC or across a network with the multi-user client, viewed in standard browser.

A standard SMC HOSY system consists of:

  • Panel Display
  • MRU Motion Reference Unit
  • Weather Station for Wind Speed & Direction, Temperature & Humidity and Air Pressure
  • GPS (provided by yacht)
  • Gyro Compass (provided by yacht)
