Critical networks

Kordia is at the forefront of maritime solutions in Australasia. From Canberra in Australia and Wellington in New Zealand, Kordia monitors nearly a quarter of the world’s oceans ensuring the safety of seafarers.

Designing, building and operating a safety network

Kordia’s Maritime Safety Communications Services in Canberra enables the Australian Maritime Safety Authority (AMSA) to communicate with vessels in distress. The AMSA uses Kordia’s high frequency (HF) radio system to provide this critical service.

Kordia designed, built and now maintains and operates the high frequency maritime communications network AMSA uses to provide their global maritime distress and safety system (GMDSS). This is a HF radio service for search and rescue operations across one of the largest maritime areas (52.8 million sq km) in the world.

The same sites also support the work of the Australian Bureau of Meteorology and transmit weather information to maritime traffic.

Desert challenges for a maritime service

The maritime safety network is linked through four unmanned remote-controlled stations in two desert locations at Wiluna in Western Australia, 1,000 kilometres north-east of Perth and Charleville in Queensland.

Each station depends on a reliable energy source. A commercial electricity supply proved too costly and impractical to set up. The options of either diesel and solar were looked at but neither were economical on their own.

Kordia engineers devised a hybrid system energy solution combining solar and diesel power supplies that was functional, cost-effective and allows operational flexibility. Engineered to be 99.999% reliable, the Wiluna energy system has a hybrid solar diesel 240 volt AC supply, as the main supply. This is backed up with two additional diesel standby generators.

Each of the eight arrays of solar photovoltaic (192 BP) cells is arranged in four modules made up of 12 individual panels (interconnected), fixed to a customised galvanised frame, and angled to optimise the panels’ exposure to the sun’s daylight passage.

The solar panel output is fed into the purpose-designed and built hybrid power hut by eight shielded two-core cables; one from each array.

Kordia radio operations and services

Kordia radio operators are at work 24x7x365 days providing the calm yet reassuring voice to vessels at sea in times of emergency. If it’s a distress call or relaying maritime operations, Kordia has it covered.

Although assisting ships in distress is imperative, Kordia also gives access to ships in need of medical advice, weather forecasts and a host of other services to vessels.

The Kordia dedicated support systems include: Automatic Identification System (AIS), vessel tracking and search capabilities and Digital Selective Calling (DSC).
