Dolphins protect passing vessels and the heritage-listed Glebe Island Bridge, which is one of the last remaining swing bridges of its type in Australia. The northern and southern dolphins were in a state of disrepair and presented a risk of collapse as Sydney entered its NYE celebration period and relied on safe passage for fireworks and other large vessels.

Port Denarau Marina provides stopover for rest, recreation and provisioning during cruising around Fiji Islands. To ensure safe mooring of a large variety of vessels, it is important the critical elements of marine assets are well maintained.
