This position is contingent upon contract award of the contract. 

Key Responsibilities:

  • Lead the technical review of historical port, mooring, pipeline, waterfront, and marine survey information; identify data gaps and additional surveys.
  • Evaluate adaptation of Queen Salote Wharf, adaptation of the Vuna Cruise Ship Terminal, and a new offshore mooring alternative for MR tankers.
  • Define technical standards, vessel assumptions, design criteria, safety requirements, and survey scopes for the feasibility study.
  • Develop and document concept-level marine and waterfront designs, berth/mooring arrangements, pipeline interfaces, preliminary calculations, layouts, project schedules, and construction workflows.
  • Coordinate with fuel systems, civil, structural, mechanical, electrical, environmental, cost, regulatory, and financial specialists.
  • Support AACE Class 4 capital cost development by establishing quantities, design assumptions, risks, exclusions, and contingency drivers.
  • Participate in client workshops, stakeholder meetings, option-selection sessions, and presentations to Pacific Energy, government entities, and other project stakeholders.
  • Prepare task deliverables and contribute a stand-alone chapter and supporting crosswalk materials for the final feasibility study report.

Qualifications to be successful in the role:

  • Bachelor’s degree in Civil, Coastal, Ocean, Marine, Structural, or closely related Engineering. Master’s degree in a relevant discipline preferred. 
  • Minimum of 15 years of progressively responsible experience in ports, marine terminals, waterfront structures, or coastal infrastructure. 
  • Technical leadership experience on feasibility or concept-design assignments. 
  • Active Professional Engineer (PE) license, Chartered Engineer status, or equivalent professional registration in a recognized jurisdiction. 
  • Preferred certifications and credentials include PMP, PIANC or ASCE/COPRI participation, OCIMF, ISGOTT, port safety, marine risk, or coastal-resilience training, and current HAZWOPER or equivalent field-safety credentials, where applicable.
  • Advanced knowledge of berth planning, vessel interface requirements, port layouts, quay and wharf systems, offshore moorings, marine loading/offloading systems, and marine pipeline interfaces.
  • Ability to apply and reconcile relevant Australian/New Zealand standards, OCIMF guidance, ISGOTT practices, PIANC guidance, and other recognized international marine design criteria.
  • Experience scoping and interpreting bathymetric, hydrographic, metocean, geotechnical, topographic, current, wave, seabed, and mooring studies.
  • Ability to develop and review preliminary calculations, basis-of-design documentation, layouts, mooring concepts, equipment lists, construction sequencing, permitting roadmaps, and contracting strategies.
  • Working knowledge of constructability, operability, maintainability, HSSE, cyclone, storm surge, sea-level rise, tsunami, seismic, corrosion, and coastal flooding considerations.
  • Ability to compare technical alternatives using transparent multicriteria methods covering safety, cost, resilience, operations, disruption, environment, schedule, and implementation risk.
