Emission control areas
None of this route is inside an emission control area (ECA). An ECA is a sea area where a ship must burn fuel with no more than 0.10 per cent sulphur, or clean its exhaust. Either costs more than sailing on ordinary fuel.
The two ports
- Singapore. UN/LOCODE SGSIN, at 1.28 N, 103.85 E.
- Colombo, Sri Lanka. UN/LOCODE LKCMB, at 6.92 N, 79.85 E.
A UN/LOCODE is the United Nations code for a port. The straight line above is the great circle, the shortest line over the globe, which crosses land.
How this was worked out
Computed on 13 October 2026 by the sea router behind the Neptune Atlas voyage estimator. It searches a grid of navigable water built from public sea depth data, so the track goes round headlands and through straits. No draft limit was set and no area was avoided. Distance tables differ by a few per cent, because each one picks its own point for a port and its own track through straits. Use it for planning, not in place of a chart.
