[Platforms] R/V Tridens and Tridens I correction

[Francis Kellie]

Dear All

Due to a spreadsheet error I recently incorrectly identified R/V Tridens as being Tridens II, owned by Chase - this was incorrect.  Record should read as follows:
ICES64TD - R/V TRIDENS -  Research vessel built 1990, length 73.54m.  Owned and operated by the Ministry of Agriculture, Nature Conservation and Fisheries. Callsign PBVO, active as at Jan 07.  IMO 8821852

Regarding the build date/name change date for Tridens I these are clarified below - they have been taken from Lloyds MIU database, length overall I've taken from the ship spec from Chase's website.
ICES64T1  (proposed code)  - TRIDENS I - Built 1968 as Tridens, renamed Tridens I on 15 Apr 1991.  Owned and operated by Chase Seismic Survey B.V.  Active as at Mar 07, callsign PIAO, length overall 60.85m.  IMO 6812833.  See http://www.css-denhelder.nl/tridens.htm 

Apologies for any inconvenience caused

Regards

Frances
