This subject was addressed in detail in my paper titled Review of Freight Car Bogie Design and Performance presented to the IHHA Bogie Conference in Montreal last year.Modern passenger trains, such as the Eurostar and the British InterCity 125 and 225, have bogies designed for the specific service requirements and are capable of providing excellent performance.

MacArtney’s MBES Hydrographic System for Island of Corsica

first_imgMacArtney France has delivered a portable multi-beam echosounder hydrographic system, designed for small vessels, to the French government organisation, Collectivité de Corse, in Corsica.The Collectivité de Corse, a government organisation, represents the interests of the community of Corsica – a Mediterranean island off the south coast of France.With 1000 km of coastline, the island attracts many tourists and cruise ships creating the need for an MBES hydrographic system.The purpose of the MBES hydrographic system is to ensure visiting vessels can securely navigate the harbours of the island, monitor the seabed to control the quality of dredging, identify obstructions on the sea floor and verify underwater installations.MacArtney France worked with Kongsberg, Valeport and SBG Systems on this project to fulfill the project specific needs and supply an adaptable MBES hydrographic system that meets the standards set down by the International Hydrographic Organisation (IHO).This new bathymetric system from MacArtney France will reduce survey time, increase accuracy, expand survey area reach and ensure a comprehensive hydrographic survey system.last_img read more
