In 2016, the Government of Vanuatu and Hawkins Infrastructure Ltd engaged Hall to undertake dredging works to improve navigational accessibility between South Paray Wharf and Iririki Island.

Hall dredged a channel 200 metres in length, 50 metres wide and 5.5 metres deep (approximately 48,000m³ in total).

The team then used the dredged coral limestone to reclaim part of the port for container space. This has enabled 60-metre-long cargo ships to use the channel, cutting significant time off their voyage.
