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.

 Merchant Tug Gerry O'Sulllivan - Port of Cork - Ireland

Retrofitting on a ship is in most cases a nightmare for any marine electronics engineer. There is usually no documentation, no space, and few ships have actually been built to date with computer networking in mind... Our chief Engineer  spent a day at sea last week with two shipmates running 30 meters of cable on a large ferry. Wireless is a nice thing, but guess what, ships are mostly made of steel, and radio-waves can’t travel through it. Besides, there is one thing a decent CAT6 will do that radio-waves

Middle watch 0000-0400 - First bell...  Today as I was unsure about the exact explanation of why we were receiving so many radiowaves in provenence of the Celtic Sea, on Saturday, I've decided to prove Cicero right one more time and I when meeting one of my student (Ian B.) who teaches Radio Communications in NMCI. 

 

As it happens with easterly wind and lots of sun heating France and the UK during the day like a giant radiator a lot of hot air pushed by the wind has acted like a super amplifier on our radiowaves. Duct effect caused

Today, a team of Sea-Technicians returned to Roches Point in order to reinstall the camera that we had removed to repair a short while ago. It was the first time that Jonathan, the new intern, travelled to the lighthouse located at the entrance of Cork Harbour. Furthermore he had never been in this kind of building, so it was very surprised with all. Jonathan is a Brazilian chap who is studying Energy Engineering in CIT, in Cork.

The first part of the morning Jonathan and I had to configure in the National Maritime College’s wet lab the setup of the

Lighthouse from the Swansea- Cork ferry – Peter Newbold – geograph.org.uk


This almost 200 years old lighthouse, unfortunately, is losing its first purpose, with the advent of gps systems (ECDIS), large vessels, have much less needs for lighthouse, making them fall in disuse.
Sea-tech have been using Rochespoint LightHouse as a station to broadcast SeaFi signal up to 30 kilometers from the coast, SeaFi allows buoy, ships and

Today was my first day working on the field, it was a great experience that made me think how important is the maintanance and management factor in Marine ICT.

Sea-Tech tackled a very ambitious project a few years ago, deliver access to computer networked resource on board vessels around Cork Harbour without using satelite or mobile phone technology. Computer networked resource assets can take the shape of an IP Camera, a thermal sensor or a weather station for example. The data produced by each asset is useful for navigation planning, security on ships etc... Spike Island host a SeaFi coastal

Today, I did my first fieldwork, and the destination was Roches Point lighthouse. To get there it took almost one hour (from NMCI) so I had a lot of time to enjoy the scenery.

We checked on the electronic research equipment in the lighthouse. It’s located at the entrance of Cork Harbour. The first light is dated, 4th of June in 1817, but it’s only in 1970 that Rochespoint was converted to electric, before it used an oil lamp system and a Fresnel lens, that’s still visible today, it’s almost 150 years old!

I studied Technical Engineering in Computer Management in Spain. I arrived to Cork in March to do a three months internship. Here in SeaTech, we deliver all sorts of Marine ICT solutions including private marine wireless data communication. In other words we provide data exchange capabilities for seagoing projects. I have to admit, I would never have imagined before it could be a problem. Sending email is something so natural, on land, nowadays, I never thought before of a person who works in a port, a harbour or simply on a vessel, may ever need to connect to Internet. Once

mv denis murphyA 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

I have "served my tour of duty" with SEA-Tech from 2008 to 2010. First of all I am very gratefull to my former colleagues in SEA-Tech. When I talked to Arnaud and he asked me to write a testimonial I was really happy, because I think the years when we worked together it was a very nice and successful time. I have been thinking a lot of the challenge of writting the story in not too many words, due to the lots of things that I learnt and experienced back then.
I joined to the company in 2008 after I
