Unique sensors for ADOC

Unique System FZE has supplied the Abu Dhabi Oil Company Ltd. (Japan) with a monitoring system providing meteorological and oceanographic data.

The system is installed at a Single Point Mooring (SPM) buoy, a large buoy at sea for mooring and filling oil tankers. It measures wave height, wave direction, current strength, current direction, water depth, wind speed, wind direction, gusts, temperature, air pressure and visibility.

The meteorological sensors are installed in a new mast which is bolted to the deck of the buoy.

Wave and current information is gathered by an acoustic Doppler current profiler (ADCP). This unit is mounted in a ballasted stainless steel frame and will be placed on the sea bed near to the buoy.

Weather parameters and sea conditions are collected by a data logger located in the central compartment of the SPM buoy. They are then relayed to the Operations Centre on the nearby Mubarraz Island (UAE) through GPRS telemetry.

The entire system will have an independent power supply. To this end, a solar panel will be mounted on the deck, near the mast, while an extra battery will be placed in the buoy’s dedicated battery room.

Unique System FZE, a Unique Maritime Group company, says that the information on weather and sea conditions will help ADOC safeguard the natural environment by preventing any mishaps or spillages.

Captain Keiji Harada from ADOC (Japan) commented: “We will carefully monitor the system’s performance over an initial period after which we will think about further extension of the data collection to other offshore installations as well.”
