Upgrading of the meteorological monitoring system (HMS) on the self-elevating drilling platform "Guozhi" on the helicopter deck

The 'Guozhi' self-elevating drilling platform is designed based on the GUSTO CJ46 standard. Its length is 69.125 meters, width is 62 meters, and the length of the pile legs is 147.4 meters. The maximum operating water depth is 375 feet. It uses NOV drilling equipment and can accommodate 120 people for living. It is classified by the American Bureau of Shipping (ABS). This platform has high-performance advantages such as strong operation capability, large variable load capacity, and good environmental adaptability. The helicopter deck is equipped with the OBSERVATOR HMS3.0 system, which aims to provide comprehensive meteorological data for the takeoff and landing of helicopters, thereby ensuring the safety of helicopter takeoff and landing as well as the personnel's safety. 

Compared with the previous version, HMS 3.0 is designed to be more compact and based on the Observator OIC (Meote link) principle. Various sensors can be directly connected to the central processing unit, which means that the wiring is reduced during installation, significantly lowering the cost for users.

The OBSERVATOR provided HMS 3.0 can interface with a wide range of meteorological probes, including wind direction, wind speed, aircraft deck pressure, sea level pressure, temperature, humidity, visibility, dynamics, cloud height, wave height, status lights, etc. The OBSERVATOR provided HMS 3.0 has been widely used in drilling platforms, FPSOs, buildings, helipads, wind farms, and various types of ships. The OBSERVATOR HMS 3.0 is based on the latest CAP-437 requirements, namely the standard for offshore helicopter landing areas, version 9. Additionally, this system also complies with the latest requirements for helicopter platform certification agencies (HCA) described in the Rev9C of the standard helicopter platform monitoring system. 

The meteorological sensor product line of Observator is very diverse. The core features can be summarized as follows: designed for different application scenarios, generally featuring high precision, resistance to harsh environments, support for multiple output methods, and optional heating function. 

The system configuration is as follows 

● Status indicator light 

● Wind speed and direction sensor 

● Temperature and humidity sensor 

● Air pressure sensor 

● Posture Sensor 

● Visibility sensor 

● Cloud height sensor
