Tidal Power Turbines Installed in Dutch Eastern Scheldt

with Tocardo Tidal Turbines, producer of tidal and free-flow water turbines, Mammoet carried out the transportation and installation work for this renewable energy project at the Easter Scheldt storm surge barrier (Oosterscheldekering). The project, known as OTP2, comprised five tidal turbines in a steel structure with a total weight of 500 tons.   The project raised a number of installation challenges for the teams involved, Mammoet said. As this is a flood defense barrier it was not possible to drill into its column, so Mammoet worked with Huisman Engineering on a way to precisely secure the

Almarin Launches Balizamar Mooring Buoys

Following on from the design of Balizamar navigation buoys, Almarin has launched the new range of mooring buoys used for mooring of vessels, as well as for containment booms and supporting floating cages used in aquaculture.   The new mooring buoys are manufactured with a galvanized steel structure with a safe working load (SWL) of 12,000kg and a foam filled rotomoulded polyethylene hull. There are four available hulls with standard diameters of 1,250mm and 1,600mm and volumes between 700 and 2,500 liters. Each model is available with four mooring designs.

New Switchable Magnet Launched as Tool for ROVs

and versatile tool for ROV operators. Incorporating patented technology that increases its performance, the magnet has been designed so that it can be switched-on and off by an ROV manipulator and used for a wide range of applications underwater. The new magnet can be applied instantly to any steel structure where it is capable of holding weights up to 750 kg and it can significantly reduce the amount of time required for an ROV to undertake a task. The Miko ROV Magnet functions completely mechanically without the need for cables or wires and permits gentle contact with painted surfaces on subsea
