Navy: $2.3B Deal for 12 Mine Hunting Ships

The Belgium Naval & Robotics consortium, composed of Naval Group and ECA Group, won the contract to supply 12 minehunting vessels to the Belgian and Dutch navies. Equipped with around 100 drones, constituting approximately 10 drone systems (toolboxes), six ships are destined for the Belgian Navy, while the other six will be delivered to the Dutch Navy.The 10-year contract is worth nearly $2.3B. After a three-year design phase, Belgium Naval & Robotics will launch the production phase of the ships and drone systems with a first delivery expected in 2024.The Belgium Naval & Robotics consortium

the added benefit of introducing a renewable component to fossil-fuel projects, whose developers are keen to show they are making their operations as green as possible.Successful testA prototype Power Hub, using one turbine, completed a successful eight-month sea trial in December 2017 at the European Marine Energy Center (EMEC) in the Orkney Islands, northern Scotland. EC-OG is now refining the system to match the requirements of oil and gas field developers. These include having two or more turbines and differing battery sizes depending on site requirements.The device being lowered to the deck of the

New Ethernet Cable from TE

TE Connectivity (TE) introduced its Raychem Cat 5e cable that offers high-performance Ethernet connectivity at speeds up to 1-Gb/s in harsh military, marine and aerospace environments.The Cat 5e cable makes use of high temperature fluoropolymers that are designed to perform under extreme temperature fluctuations from -65°C to +200°C. Designed in accordance with ANSI/TIA-568-C.2, the cable is both lightweight and easy to terminate, the manufacturer said. TE’s waterblock variation uses super absorbent tapes and yarns that further help reduce weight, increase flexibility and lower installatio
