Misc.
We would like to highlight the exceptional
good manoeuvrability of the vessel. Also please note the environmental
bonus using ”Tor
Viking II” due to her exceptional low noise level, and
the installed Exhaust Gas Treatment Systems (Catalyst), effectively
reducing the NOx levels. ”Tor Viking II” is also
equipped with diesel overflow tank with alarm system. The vessels
design, and her possibility for running 2 engines, (“father/son”)
gives very favourable fuel consumption.
Spooling Devizes and
DynPos 2 – Kongsberg Simrad SDP21 – “DP
Green” system were installed in May 2003
