IMG 4521Cork (Ireland) - 05 June 2018 (Press release) - Sea-Tech Evolution Ltd. is a Cork based company specialising in maritime communications. It will formally establish this week the record for the longest wireless internet communication at sea, using it’s on-house bespoke developed SeaFi communication system which is far more capable than land based systems such as 3G or 4G at sea.

There are currently two possibilities to send/receive communications at sea: satellite, or cellular systems such as the 3G used by your mobile phone. SeaFi offers a new third option.
In a few lines, here is what it is, and why this record is important.


SeaFI in a nutshell :

SeaFi facilitates the creation of private networks in ports and coastal areas by establishing connection between lighthouses, maritime wind turbines, or offshore drilling platforms and vessels at sea. These networks are used to connect the ships and their crews, as well as the data collection buoys (weather, tides...) for example. SeaFI is a radio system on the band frequency of 2.4 GigaHertz which works a little like Marconi's telegraph system, using coastal stations (connection points) and embarked stations at sea.

Nautilus International’s crew communications campaign has highlighted the case for ports to provide wi-fi services for visiting vessels – and now a young Irish company is boosting seafarer welfare and ship efficiency with a special port-wide wireless network service... 

Ireland - an island nation relying on shipping for more than 95% of its imports and exports - is taking a lead in developing the concept of ‘smart’ ports, thanks to a pioneering project that was launched by a group of self- confessed ‘garage geeks’.
Launched just over a decade ago, the information and communication technology (ICT) firm SEA-Tech Evolution has developed the SeaFi service – a special wireless network system. described as ‘a different way of sending data in a marine environment’.

A project that has allowed the Port of Cork to precisely monitor and record the winter program of seabed ploughing in real time for the first ever time is being delivered by Succorfish in partnership with Irish marine communication specialists SEA-Tech.

The groundbreaking exercise, which is being carried out aboard a utility vessel working to lift sediment from the port seabed into the water column and back out to sea, sees live, up-to-the-minute and highly valuable location data transferred back to officials instantly in real time. And, given its success, it is anticipated that it could change the way future ploughing operations are carried out as well as greatly improve efficiency for the world's second largest natural harbour.

Rittal Ireland are delighted to announce their partnership with SEA-Tech
Evolution which enables both companies to grow their presence in the marine industry.

Products such as the Rittal 316L stainless steel enclosure protect critical equipment in harsh environments under the most demanding conditions are particularly suitable for SEA-Tech projects. Design elements like blind nuts on the back side that insure a snug fit and make flush- to-the-wall installations a snap. When measuring tools and critical controls need protection from the elements, inside or out, Rittal’s durable, onepiece, space-saving wallmount designs are particularly suitable on marine projects.

Using a GPS and RFID solution from Succorfish, IT services company SEA-Tech will help the Irish port monitor when and where a plow is lowered to the seafloor.

Ireland's Port of Cork is about to begin a trial of a vessel-tracking system that includes radio frequency identification technology, in order to obtain an electronic record of which areas of its seafloor are being dredged, and when. This will ensure that the port continues to upgrade the portage waters at the proper time and place. The RFID technology is part of a larger solution that employs GPS, cellular and satellite technologies to identify and report a vessel's location. With RFID, the system will indicate not only where the boat is located, but also when it has lowered or raised its plow into the water in order to scrape and level the seabed.

Following a successful trial period, the Port of Cork has announced details of their partnership with Ringaskiddy based company Sea-Fi Marine Data Communication Ltd. Sea-Fi is a wireless network covering the navigational areas of Cork Harbour, from 12Km off Roches Point and for the last six months Sea-Fi have provided Wi-Fi on board the Port of Cork owned vessels, MV Denis Murphy and MV Gerry O'Sullivan.

This has proved very successful with the work vessels able to send and receive emails, images, and gain access to web cameras around Cork Harbour. It has also proven a time and money saver, eliminating the need for the work vessels and crew to go back to base for administrative purposes to process time-sheets, etc., as this can now be completed on board.

From real-time cargo tracking to crew and passenger management applications, Windows-based radar to floating data centres, ocean-going vessels are increasingly taking on-board the benefits of ICT.

One could be forgiven for assuming that the maritime industry would be one of the most advanced users of information and communications technology. Navigation,'logistics, efficiency - these are all crucial to the sector, and very much the domain of ICT. But step aboard the average ocean-going vessel and you're likely to see computing equipment that many landlubbers would consider decidedly behind the curve.

Maritime environments are not only life-critical, but they are also largely autonomous. Vessels of many kinds will be offshore for months at a time, and in many cases, such as on cargo ships, they will be staffed with a skeleton crew. They cannot afford for the equipment to go wrong.
