I’m confused about ‘maintenance’ and ‘capital’ dredging. What is the difference?
Regular maintenance dredging is carried out to prevent the natural occurance of silting up. Otherwise the channel would soon be too shallow for most port operations.
This dredged spoil is barged out and dumped in a hole past the entrance to the Trinity Inlet. Dredging is carried out within strict regulations.
Capital dredging is a one-time project to deepen and widen part of the port. Dumping spoil from capital dredging at sea has recently been banned.
Putting spoil on land is usually more expensive than dumping it at sea.
