Sunset Dredging
The dredger Mareta working through sunset into darkness to deepen the channel into Olhão marina. Presumably operations were governed by the time of the tide.
The dredging was a relatively simple operation with a ship-mounted grab crane digging up buckets of sediment and dumping them into the hold. Once the hold had been filled - making the ship very low in the water - the ship steamed outside the Ria Formosa to dump the load.
