Harbor workhorse

This is the Pelican, A dredge that has been working to clear the harbor entrance so that ships may enter and leave without the fear of grounding. They have been working for three weeks, 24 hours a day.
This ship traverses New Zealand's coast's keeping our ports clear of silt.
She may not look glamorous, but this ship is fundamental in keeping New Zealand afloat (pardon the pun)
