Environmental Impact and Risk Assessments

Aquenal has conducted environmental impact and risk assessments and associated baseline and monitoring studies for approximately 50 projects, including proposed developments, existing industries, infrastructure upgrades, and regional plans. Studies performed can be allocated to the following marine industry categories:

  • Shipping, wharves and jetties
  • Dredging and reclamation projects
  • Offshore infrastructure and submarine pipelines and cable installations
  • Marinas and foreshore developments
  • Effluent outfalls and thermal discharges
  • Aquaculture activities
  • Paper and pulp mills
  • Transport infrastructure and multi-use strategic land developments
  • Mine sites and heavy metals investigations
  • Tourism developments
  • Combined activities at the land-ocean interface (regional planning)
