PORT OF OMISALJ APPROACH
Depth outside Omisalj bay is approximately  55 m, inside bay 30 m with mud and rocks bottom, width at entrance to bay approximately 700 m. The port of Omisalj is approached by Vela Vrata, the main channel, which connects Kvarner Bay with the Bay of Rijeka. A Traffic Separation Scheme has been established in Vela Vrata.

Large tankers proceed from Vela Vrata to the N part of Rijeka Bay, making a large turn before steering for Omisalj inlet.
Chemical tankers and gas carriers may follow a more direct route for the entrance to Sepen Bay.
The approach channels to both terminals are marked by lights and light buoys.

TIDES/CURRENT/WEATHER
The maximum tidal range in the bay is normally 1.1 m (3’06”), but the height of tide is much affected by wind conditions. In strong SE winds it may be increased by up to 0.6 m (2′) and in strong NE winds, the low water may be as much as 0.3 m (1′) below.

The currents near the terminals are negligible, but in Vela Vrata the S-going current may attain a velocity of 4 knots during strong NE winds.
Winds from NE and SE prevail. During the winter season NE winds Bora can reach hurricane force; SE winds may form waves of up to 3 m in Rijeka Bay.
