Voyage Summary
Winter Baltic voyage from Porvoo (Sköldvik) to the Skaw STS area off Skagen – three days, 819 nm, westbound through the Gulf of Finland, across the Baltic, and out through the Danish Straits. The entire route runs inside the Baltic and North Sea SECAs, so the 4.9 MT FOC saving is realized entirely on ECA-grade fuel. The optimized track held at a 1.03 m mean significant wave height with a 2.68 m peak in the southern Baltic, and reduced Sea State 5+ exposure from 12.0% of the historical track to 1.5% – about 90 minutes of brief Sea State 5+ conditions versus roughly 9 hours on the historical replay. Mean SOG 11.31 kn.
