ELECTRIC HVDC TRANSMISSION INDUSTRY |
HVDC Electric Transmission Industry
The Principal of EnviroGulf Consulting (EGC) has local and international experience of high voltage direct current (HVDC) interconnector projects with marine components such as subsea HVDC, electrode and optic fibre cables and sea electrodes.
The Principal completed a 2-year assignment for the Basslink Project, which proposed an HVDC link between the Australian mainland (Victoria) and Tasmania. In support of the Basslink Project, the Principal carried out an environmental review and site visit of existing HVDC interconnectors in Sweden, Norway, and Denmark. The monopole Basslink Interconnector with a metallic return cable is now in operation.
The Principal is also a member of the Institute of Electrical and Electronic Engineers (IEEE).
EGC has compiled a world list of HVDC Projects with Marine Infrastructure, which shows existing and proposed HVDC interconnectors.
Consulting Services
EGC offers the following services to clients:
- Critical review of existing literature, reports and databases on marine environmental impacts of subsea HVDC projects and operating cables and sea electrodes.
- Calculation of generated magnetic fields.
- Calculation of generated and induced electric fields.
- Environmental impact assessment of construction phase including installation of underwater or subsea HVDC cables, optic fibre cables and marine electrodes and shore crossings.
- Environmental impact assessment of operating underwater or subsea HVDC cables, such as the physical effects of generated magnetic and thermal fields, generated and induced electric fields, and electrolysis products (e.g. residual chlorine) and residual impacts after mitigation on cetaceans, sharks and rays, bony fish, turtles and marine plants and invertebrates.
- Review of post-operation and decommissioning aspects of subsea HVDC cables and marine electrodes.
- Design, implementation and execution of marine surveys and/or monitoring programs to assess the marine impacts of subsea HVDC cables and/or electrode installation and operation.
- Marine ecotoxicological assessment of chlorine produced oxidants (CPOs) and halogenated organic compounds (HOCs) generated at the positive marine electrode (anode), including dilution-dispersion modelling, predictive toxicity assessment and contaminant pathway analysis.
- Project management for marine studies, including co-ordination of multidisciplinary teams, government and regulatory authority liaison, quality assurance and quality control.
- Environmental review: Environmental review and audit of existing environmental management systems (EMSs) and environmental troubleshooting.
- Environmental monitoring: Monitoring design, planning and implementation, baseline/inventory monitoring, compliance monitoring, sampling and analysis planning, biomonitoring and surveillance.
- Risk assessment: Preliminary risk assessment, hazard identification, dose-response and exposure assessment, risk characterisation, and ecological risk assessment.
- Information management: Data processing, statistical analysis, quality assurance/quality control.
- Peer review of EIA documents for other HVDC projects.
- Expert testimony on marine environmental impacts of constructing (installing) and operating HVDC interconnectors with subsea infrastructure.
EGC has access to electrical engineering consultants having a proven track record in providing cost-effective services to the electric industry. In addition, DBA has access to recognised specialist scientists on cetacean and shark biology and population dynamics, and who are familiar with electromagnetic impacts on the marine biological environment.
Relevant Experience
The Principal of EGC has carried out an intensive 2-year study and marine impact assessment of constructing and operating a subsea, monopolar HVDC interconnector with marine electrodes (plans for marine electrodes were subsequently withdrawn in favour of a metallic return cable). Work included:

- Principal author of the existing marine environment (Chapter 7) and marine impact assessment (Chapter 10) presented in the Basslink Project DIIAS, June 2001.
- Principal author of the marine impact assessment (Appendix E) presented in the Final Environmental Impact Statement and Supplement to the DIIAS for the Basslink Project, June 2002.
- Conducted international research and site visits to existing and proposed HVDC interconnectors in Sweden, Norway, Denmark and The Netherlands, October 2000.
- Expert Witness appearing on behalf of Basslink Pty Ltd at public hearings in Victoria and Tasmania.
- Conducted review report on the effects of ac electromagnetic fields on marine life for Offshore Hydrocarbon Mapping Limited (UK).
