OBSERVATOR Explosion‑proof Weather Sensor Station Supports Wison FSRU Project F462

FSRU stands for Floating Storage and Regasification Unit. Vessel F462 has a storage capacity of 45 000 cubic metres with a 20‑year design service life. Moored at a berth with approximately 25‑metre water depth via mooring lines, it allows emergency evacuation under tsunami alerts. The regasification system is designed for a peak continuous output of 166.5 MSCF; regasified gas is delivered to on‑land power plants for power generation.

The OBSERVATOR intrinsically‑safe explosion‑proof weather station is deployed on this FSRU. It monitors wind speed, wind direction, air pressure, temperature and humidity in real time. It mainly supports safety monitoring for helicopter deck landing‑and‑take‑off operations, provides meteorological reference for single‑point mooring and LNG cargo transfer, supplies meteorological correction data for navigation systems, and complies with explosion‑safety requirements and maritime regulations for offshore oil‑gas installations.

Product Introduction

OBSERVATOR OMC‑118IS

OMC‑118 I.S. Intrinsically‑safe Ultrasonic Wind Sensor

Developed for hazardous‑area applications, the intrinsically‑safe WindObserver sensor is especially suitable for offshore operations. Built on cutting‑edge technologies and Gill’s extensive expertise in solid‑state anemometer manufacturing, this lightweight, rugged, fully‑sealed sensor is constructed of stainless‑steel materials.

Key Features

- Certified to EEx ia IIC T5 explosion‑proof standard

- Shore‑based maintenance‑free

- Stainless‑steel construction

- Galvanically isolated power supply

- NMEA protocol output

- Wind‑speed measuring range: 0‑75 m/s

OBSERVATOR OMC‑408

OMC‑408 Ex Temperature & Humidity Transmitter

For factories, vessels, LNG terminals and offshore facilities, engineers prefer to install measuring instruments outside hazardous zones whenever possible. However, optimal mounting positions for meteorological and hydrographic sensors sometimes lie within hazardous areas.

All marine weather sensors from Observator are available in explosion‑proof versions complete with required ATEX certification certificates. Consisting of sensor probe and transmitter, the unit delivers safe and accurate temperature‑humidity measurement for Zone 0 and Zone 1 hazardous locations.
