GEM M [MHMS the propellers are constructed using a special, high strength steel, which makes crafting them more difficult than tradi- tional bronze models. The pro- pellers feature the additional strengthening to add to their service life (anticipated at 15 years), due to the large amount of time the props are cavitating due to the nature of icebreak- ing work. ECHO Project Update Electronic Chart Display and Information Systems (ECDIS) are being counted on to improve safety at sea while making the working life of those onboard easier, particu- larly in regard to time saved updating and organizing paper charts. The ECHO (European Chart Hub Operations) project began in April 1996 with the aim of produc- ing a prototype commercial service for the storage and distribution of ENCs. Led by Norway's Electronic Chart Center (ECC), the project is partially funded by the EU and includes many international organizations and manufacturers, including the Finnish Maritime Administration, Sysdeco Dikas AS, ASPO, Telenor, the U.K. Hydrographic Office, Inmarsat, IONA Technologies and Sintef. Production of ENCs to the IHO's standard S57 edition 3 has begun in several centers, and the volume of available data continues to grow. The ECHO project has linked the U.K. and Finnish Hydrographic Offices, who sup- plied their charts and updates via ISDN con- nections to the ECC. The ECC operated as a regional ENC Coordinating Center and pro- vided end-user services from where the data were available on demand to the vessels 24 hours a day. Communications with the ECDIS equipment onboard utilized Inmarsat-B high speed and GSM connec- tions, but any communications medium sup- porting the widely available TCP/IP protocol could be employed. These links allow instantaneous updating of charts while at sea, a key plank in the ECHO project. Close attention has been paid to the security of data and cost of transmission, to ensure the project represents a viable commercial ser- vice.
