As part of Australia’s Pacific Maritime Security Program, the Pacific Patrol Boat Replacement (SEA3036 Phase 1) initiative is delivering a new generation of Guardian-class patrol boats and supporting infrastructure that will strengthen maritime security across the region. The program replaces the original Pacific Patrol Boat fleet provided to Pacific Island nations and aids with enhanced border protection, fisheries surveillance, search and rescue, and regional security operations.
We provided multidisciplinary engineering services to support the planning, design, and delivery of maritime and landside infrastructure upgrades. These were required to accommodate the larger and more capable Guardian-class patrol boats across Papua New Guinea, Fiji, Solomon Islands, Vanuatu, Tonga, Samoa, Kiribati, Tuvalu, Nauru, and Palau.
Following site inspections and an assessment of the existing infrastructure, we developed detailed designs for repair works to those structures as well as the design of new quay walls and jetties. We also provided a survey of unexploded ordinance, geotechnical and topographical investigations, and cadastral and bathymetry surveys. Additionally, we supported the construction of new and upgraded wharves, jetties, pontoons, mooring facilities, navigation infrastructure, utilities, pavements, and associated landside works.
Delivering infrastructure across remote island environments required close collaboration with government officials, defence agencies, local authorities, contractors, and local communities. Our designs addressed challenging site conditions including tropical and cyclone-prone environments, durability, constructability, and long-term maintenance requirements. This allowed us to reduce disruption to active port operations and deliver sustainable, resilient infrastructure outcomes.
The upgraded facilities strengthen sovereign maritime capability and contribute to the safety, security, and economic wellbeing of Australia's Pacific partners through improved maritime infrastructure and regional resilience.
