New Mandorah Marine Facility

Overview

Design and construct of an all-weather, dual-berthing facility to safely accommodate the ferry vessel operated by SeaLink between Darwin and Mandorah

DLI Northern Territory

Construction of a safe harbour formed by rock armoured breakwaters – large northern breakwater and smaller southern breakwater – including significant dredge works.
Capital dredging of an access channel, turning basin and berthing areas.
Construction of a new single lane boat ramp.
New floating pontoon and gangway ferry terminal.
260 steel tube building piles driven into rock within the harbour ranging from 700-1350mm diameter, high capacity Junttan HHX300 hydraulic hammer.
DDA compliant access from the carpark to ferry berthing facility.
- Improvements to land side facilities.

SMC provided a full alternative design as part of our tender, maintaining the performance brief, but with significant benefits to the client.

Reducing the required volume of armour rock by ~55%.
Reducing dredge of Outer Channel silty material, resulting in a significant reduction of plume dispersal at the offshore dredge disposal site, and 30% material reduction
Providing superior protection from the prevailing ocean and tropical impacts by re-shaping the facility and improving harbour performance, ultimately providing a safer, more operable facility, requiring less maintenance
