On June 6th 2018, a scientific experiment has been conducted by SEA-Tech under control from a group reputable witnesses composed of maritime professionnals, researchers and reporters. The purpose of the experiment was to set a world record for the furthest maritime broadband transmission without satellite or cellular network using SeaFi wireless maritime communication system.

IMG 4521Sea-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.

Scientific applications of marine data communication

Belfield campus.
I was privileged today to deliver a short lecture to the students of Professor Dias in UCD. It was totally unprepared and probably I should not use the term lecture as presentation is probably more appropriate. The term presentation has a commercial connotation which was not intended in this case  . Beside, when a presentation is designed to educate, then it is a lecture in its own right. Belfield campus in Dublin is far from my dear Naval College in Cork, where a new Marine ICT lab is taking shape in preparation for next semester. When I say

The Cork Connection

Nautilus Telegraph March 2018 Edition

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

Almost six hours busing and 2 hours flying from our Cork base to RITTAL's HQ, in the heart of Germany, where our smart cabinets are made.

Noel Maloney and Charmene Walker from Rittal Ireland are my guides for this journey. They explained to our group that Rittal is part of the Loh Group, 54 subsidiary sites , 18 global production sites and annual revenue of around $2 billion. All figures I had heard about without taking the true measure of it before today. Rittal is the leading company, and supplies enclosures, climate-control technology, power distribution gear and IT infrastructure… They

Bianca 2My name is Bianca Gedorio and I’m a college student in Cork College of Commerce, studying Computer Science. For two weeks, I am working for Sea-Tech.

I began my internship/work experience, as a technical support junior technician, on the 15th January and I enjoyed the amazing learning experience! Arnaud Disant, the Chief Technical Officer, has taught me a wide range of knowledge in both technical and life skills in a span of just two weeks!

For example, he showed me how radiowave works, like inside an antenna, and use it to create solutions on how to improve communications and

Merry Christmas

Today well over a million men and women live in the twilight world of big shipping (Source SCFS). They are responsible for most of the goods you will be consuming over the Christmas season. It's a lonely life. They don't get to spend Christmas with the family. They roam the world's oceans for up to 12 months at a time. They come from more than 100 different nations and speak dozens of language. For most of them accessing the internet is synonym of keeping in touch with the family.

This year we have worked with Port of Cork, Rosslare and

Rittal partnership

If you are familiar with Electric the magazine (and website) for the Irish Electrical Industry you will have probably noticed Rittal Ireland has announced a partnership with SEA-Tech Evolution. Building on each other's reputation the two companies have a lot to share. But what does it means practically… to our customers?

Automation, Sensing & Monitoring: 
Specialising in network infrastructure both ashore and afloat, we have delivered innovative, secure, often bespoke ‘total solution’ projects, in the maritime as well as terrestrial environments. Automation Systems extends Rittal’s comprehensive range of solutions for panel building and switchgear engineering – from manual tools to fully automated mechanical engineering

Recently at the National Maritime College of Ireland open day 2017, Nautilus International magazine challenged the next generation of seafarers with this very simple question: "Would the amount of Internet access affect your decision to work at sea?" An obvious yes brought us to the conclusion we are on the right path... We would like to take this to the next level with a series of polls. Our first one will help understanding the situation on board ships. If you are a seafarer, if you have been working at sea in the past couple of years, we'dlike to hear about you...

ms stena horizonMS Stena Horizon crew welfare powered by SeaFi

For the past three months, the crew of MS Stena Horizon is involved in a ship to shore experiment designed to dramatically improve crew welfare on board ferries across Europe.
SEA-Tech Evolution is developing SeaFi as an alternative to Satellite and Long-Term Evolution (LTE) a.k.a. 3G/4G with a view to improve IoT on board ships. SeaFi is already available in three major ports in Ireland - Cork, Waterford and Rosslare. With support from Stena and Rosslare Europort, SEA-Tech has equipped MS Stena Horizon with state of the art long distance wireless communications.

IMG 1090In 2016, in a green village in France called Saint Germain, some technicians from SeaTech came from the Emerald Isle to build a smart village system. It was a large network construction and when came the moment to power their devices to the smart box, technicians wondered what kind of magic would provide data and power both in a single connection cable.
The solution came from Texas, WifiTexas more specifically. Thanks to their POE injectors the green giants from SEA-Tech would help the villagers and plenty of sensors and cameras were powered, saving endless runs of useless electrical wire… Good
