Project Summary

The upgrade to the existing wharf at Alotau is primarily to allow for international cruise ships to visit Milne Bay Province as part of the Tourism Development Strategy of PNG.

Madsen Giersing (MG) was appointed by Curtain Bros to provide the detailed design and technical support services for the design and construct contract for the upgrade to the existing International Wharf in Alotau Port to accommodate 56,000 DWT cruise ships and 20,000 DWT cargo vessels.

The project consisted of an upgrade in capacity of the existing 93m by 14m wharf, a new berthing dolphin with a linked walkway from the wharf and four mooring dolphins accommodating 100 tonne bollards.

Due to a tight construction timetable, MG designed the upgrade of the wharf by utilising the existing wharf capacity. Additional 610OD x 16WT piles were driven through openings made in the existing deck. These piles were integrated into the wharf by casting a 600mm thick concrete slab on top of the existing deck.

In order to reduce the onsite construction time, MG utilised precast concrete units for various elements. These included the berthing dolphin and the fender support panels along the wharf face.

The first cruise ship (2000 passenger) called at Alotau Wharf on the 4 Novemeber 2013.
