PORTFOLIO

Project South: Open Ocean Salmon Farm

Location: Foveaux Strait, New Zealand

Project South is a proposal for what is likely to be New Zealand’s first offshore salmon farming operation.  Offshore aquaculture can provide advantages over the sheltered areas where fish farms are normally located, but it comes with the challenges of the open sea.

ADS’ role in this project involved assessing environmental impacts for the proposed offshore salmon farming operation.  ADS performed seabed survey of benthic organisms and sediments, hydrodynamic modelling including wave and current attenuation by the proposed farm structure,  depositional modelling, and nutrient modelling.

Special EIA for Proposed Development at Lok Kawi Resort City – Hydraulic Modelling

Location: Kota Kinabalu, Sabah, Malaysia

Resort City at Lok Kawi, Malaysia is a new proposed tourism and commercial development on the coast, near the capital of Sabah, that will include land reclamation.  Due to the size of the project and sensitive nature of the surrounding area, a “Special EIA” was required to be performed.

ADS performed hydrodynamic modelling to assess the marine impacts.  Through the hydrodynamic modelling, we were able to assess potential impacts relating to sediment transport, sediment plume, water quality, waves, and more.  Special consideration was given to potential impacts to areas in the vicinity of the project that have been experiencing beach erosion.

Environmental Monitoring and Metocean study – Macquarie Harbour

Location: Tasmania, Australia

A long-term (2014-present) environmental monitoring and data collection project. The project aims to track the evolution of the water quality as the aquaculture production increases in the harbor. At the same time, Metocean data is being collected to assist Hydro Tasmania in determining their impacts on the near shore coastal environment.

Fresh Water Resource Study – Mantanani Island

Location: Mantanani Island, Malaysia

Analysis of freshwater resources on Mantanani Island for the UN small grants program. This project was undertaken to assist local villages to better manage their fresh water resource. Elements of the study included water quality analysis of existing wells and pump test analysis.

Assessments for Oil Exploration by ExxonMobil Off the Coast of Borneo

Location: Borneo Coast, Malaysia

Environmental and social risk assessments for drilling operations off the coast of Sabah, Malaysia.

Nutrient Modeling for Proposed Aquaculture Farm Site in Storm Bay

Location: Tasmania, Australia

ADS developed a computer model to examine the potential impacts of a new proposed aquaculture site in Storm Bay. In addition to the development of the model, field studies were performed and data collection devices were deployed to determine conditions in and around the proposed site.

Sabah Port and Oil Terminal Development – Land Reclamation Impact and Oil Spill Modeling Study

Location: Kota Kinabalu, Malaysia

ADS performed field sampling and developed a computer model to predict the impacts of two land reclamations on waves, currents, and coastal nutrient transport. Additionally, a computer model was developed to examine the potential impacts of an oil spill in and around the port.

Coral Reef Environmental Monitoring – Samalaju Port

Location: Bintulu, Malaysia

Periodic monitoring to regularly assess and mitigate any potential environmental impacts to the coral reef habitats in the vicinity of the port. This project composed a portion of the environmental monitoring programme requirements of the port.

Environmental Monitoring Program Sampling at a Proposed Oil Tanker Location

Location: Miri, Malaysia

ADS performed water quality, sediment, and benthic sampling around a proposed oil tanker location at the F9 oil field in Miri, Malaysia. This sampling formed part of the yearly reporting requirements for Petronas. The collected samples were compared against samples from previous years and a number of statistical analysis techniques were employed to compare and contrast the latest samples to the previous samples.

Pelagic Oxygen Demand Study – Macquarie Harbour

Location: Tasmania, Australia

This project consisted of a number of phases and included several research trips to examine pelagic oxygen demand in different parts of Macquarie harbour, Tasmania. Areas examined included in and around fish cages, rivers, and the open ocean. Isotope tracers were used to trace the exchange of nitrogen pathways inside the water column by taking water samples and examining the tracers in a laboratory. ADCP were deployed to examine the water exchange at key locations within the harbour to help calculate harbour water retention time.

Computer Modeling for EIA for Proposed Resort, Jetty, and Theme Park Development

Location: Labuan, Malaysia

ADS provided the computer modeling component of the EIA. The models included, waves, currents, and 3D profiles for the proposed reclamation and development project.

Computer Modeling for EIA for Proposed Waterfront Development in Kota Kinabalu

Location: Kota Kinabalu, Malaysia

Conducted Bathmetry survey and ADCP current meter deployment plus a numerical modelling study for a reclamation and Jetty development.
