The International Transport Workers’ Federation (ITF) said around $180,000 has been paid to some of the Indian nationals working on two vessels in the North Sea.
Around 15 workers on a vessel in Aberdeen and one in Great Yarmouth were left stranded after the ships were detained in June.
A routine inspection revealed large amounts of wages were owed to the staff on the Malaviya Seven.
The ITF said 15 crew members had not been paid for at least four months.
An inspection of its sister ship, the Malaviya Twenty, had also found the same.
In total, more than $250,000 was owed to current and former crew members, all from India.
Paul Keenan, ITF inspector, is assisting the crew in Great Yarmouth.
He said: “Last Friday the 12 remaining crew on board were paid their salaries up to end of July. Seven of the crew were also relieved last Friday when new crew joined the vessel. Another crew member will be repatriated this week. The total wages recovered so far are $180,000.
“However, there are still three crew members who were repatriated for family/medical reasons and haven’t received their money – around $250,000.The ship will remain detained until those three crew members have been paid. In addition the previous crew, most of who left last December, are still owed USD172,000, and we continue to fight for justice for them.”
