Sri Lanka has been a point of interest for centuries, owing to its strategic location on the East-West shipping route. Whilst the Colombo Port is relatively new, the Ports of Trincomalee and Galle have held historical significance. The port of Trincomalee in particular is a large natural harbor that has the distinction of being ranked the second best natural harbor in the world. It has held strategic importance for the Portugeuse, Dutch and British.

Galle Port on the Sourthern tip of Sri Lanka is a few nautical miles from the major East-West shipping route, and thus used frequently for a variety of services, including crew changes. The Outer Port Limit and Anchorage areas of Colombo Port are a hotbed of bunkering activity, with many vessels choosing to anchor at these areas for the sole purpose of replenishing bunkers.
