Forty sailors from blockaded Iranian tankers taken ashore in Sri Lanka
At least 40 sailors from US-sanctioned Iranian tankers were brought ashore at Galle over the weekend for medical treatment. Around 12 empty Iranian tankers are anchored off the port, unable to sail home because of the blockade.
At least 40 Iranian sailors from US-sanctioned oil tankers were landed at Galle, 115 kilometres south of Colombo, and taken for emergency treatment, AFP reported on 25 October. Thushara Rodrigo, a spokesman for Sri Lanka's foreign ministry, said the ministry had coordinated the transfer and the Iranian embassy had covered the costs. According to AFP, all of the roughly 12 Iranian tankers anchored near Galle are empty.
AFP says Iran's other merchant vessels, like the tankers off Galle, cannot return home to load because of the US blockade, and many have drifted towards the Strait of Malacca and Singapore. Sri Lanka maintains that the ships sit in international waters beyond its 12-nautical-mile limit, and it monitors them with reconnaissance aircraft and patrol boats. Gulf News also reported on 25 October that at least 40 sailors from sanctioned tankers had sought treatment at Galle.
The standoff is not new, though the figures in this paragraph are two months old. The Sunday Morning reported on 23 August that 16 Iranian-flagged very large crude carriers were being tracked off Galle on 21 August, and that one of them, MT Amber, had been at anchor since 16 July. The same report quoted a Sri Lankan deputy minister as saying the government could not tell which of the 16 vessels were sanctioned, because the US list had never been formally communicated through the foreign ministry. Local suppliers are therefore exposed to secondary sanctions risk.
Talay assessment
Bottom line
The dozen or so empty tankers off Galle show the blockade is locking up Iran's oil exports in its fleet as well as its cargoes. Because the ships cannot get home to load, any recovery in exports would take weeks even if the blockade were lifted. The likeliest path is a continued standoff, with coastal states raising sanctions risk more often.
Likely effects
- Iranian exportsNegative1–6 months
With part of the fleet idling empty in the Indian Ocean, first loadings would lag by the time it takes the ships to sail back to the Gulf, even if the blockade eases.
- Coastal statesNegativeWeeks
Countries such as Sri Lanka are caught between humanitarian duty and secondary sanctions risk, making suppliers and banks more cautious.
- Maritime safetyNegative1–6 months
Ageing tankers left at anchor for months raise the risk of fire and spills, and Sri Lanka has limited capacity to handle an offshore spill.
Possibilities, ranked
- 1The standoff continues60%
The blockade holds, tankers wait empty around Galle and Malacca, and crew transfers recur.
Watch: New transfer statements from Sri Lanka's foreign ministry and the tanker count off Galle
- 2The fleet shifts east25%
The remaining ships also move towards Malacca and Singapore, emptying the waters off Sri Lanka.
Watch: The tanker count off Galle falling below 12
- 3Blockade eases, ships head home15%
A US–Iran arrangement loosens the blockade and the tankers return to the Gulf to load.
