The Wilson Dublin cargo vessel was there to collect 3,500 tonnes of chipping from Corca Dhuibhne which is being brought to the UK for use in roads construction.
Arkil Ltd, the Lispole quarry, has secured a deal which will see some 50,000 tonnes of this sandstone aggregate shipped to Britain over the next year.
It's expected up to five jobs will be created locally.
Afloat.ie adds that the 2,452 tonnes cargoship was the largest ever to come alongside the pier at the south-western harbour.
Wilson Dublin has since departed and is currently underway in the English Channel.
She is bound for the Port of London at Gravesend on the Thames estuary.
