Conventional steel buoys are relics from 19th century, from the times before internet and e-Navigation. Deployment and maintenance comes expensive.
Polyethylene navigation buoys saves costs, because lighter vessels and moorings and less maintenance is required.
Polyethylene navigation buoys have been used in Finland since 1976. Even today 30.000 units of SeaHow navigational aids and buoys of different type are in use, including many Ice Buoys for winter time.
Regarding rotationally moulded modular buoys, we co-operate with Go Deep International
The lighter weight of the buoy and the moorings enables the use of smaller tender vessels and boats and cranes.
Slim shape of a spar buoy together with bigger draft is exposed to smaller drag force caused by the waves. Spar shaped body is superior in ice.
A spar type of buoy is not a wave rider like a conventional buoy, thus the movements are calmer resulting less wear and tear of the mooring.
Polyethylene does not corrode and the colors do not fade.
One of the buoy types to be tested in the Intelligent Sea project is the Sniffer buoy, in other words an intelligent seabuoy, that is capable of measuring the SOx (Sulphur dioxide) levels of air
The official kick-off event of the project was held on the 12.11.2019. Among the participants where the INEA, project partners Port of Naantali and Ports of Stockholm as well as Finnish Transport Infrastructure Agency and Swedish Transport Administration.
Neste Corporation and Meritaito have entered into a service contract, the purpose of which is to create of a comprehensive operations model for the provision of Neste’s waterway maintenance services. Meritaito’s InSea service concept can also be applied to other Neste establishments in Finland.
Port of Helsinki has upgraded ten buoys into smart, modern navigational aids. The new buoys are part of Meritaito Ltd.’s InSea service concept.
