GHD conducted one of the most comprehensive ambient air monitoring programs ever to be undertaken by an Australian company, on the remote Burrup Peninsula in Western Australia.

The project, for Woodside Energy, on behalf of the North West Shelf Venture, involved GHD’s environmental team designing a program to monitor the ambient and occupational air quality around the Karratha gas plant and offshore facilities, particularly for benzene, toluene and xylene (BTX) emissions.

Australia is at the forefront of solar research and development and the Australian Solar Institute's work is looking to keep it there.

GHD has been awarded a contract to provide the Australian Solar Institute (ASI) with ongoing communications support. The work involves the delivery of a long-term communications plan, a variety of communication materials and the provision of ongoing communications support.

A ‘Black Start’ is the complex process of restoring power supply without external power, following total failure of the power grid.

GHD used its international network to source and confirm a suitable generator to provide 'Black Start' capability to Eraring Power Station. From previous experience with second hand gas turbine projects, we were able to use our internal resources in Newcastle, Perth and the UK to select a suitably sized and priced gas turbine coupled with a new 'oversized' generator for the demanding starting loads. The gas turbine was refurbished in Dubai, and we provided on-site quality inspections of the new generator, which was sourced in the UK.

Chile was a country with a heavy reliance on hydropower and gas fired combined cycle. However, a crisis in the supply of gas to Chile forced many of the gas fired plants to swap to expensive imported oil as replacement fuel. The long term solution for base load power is the development of coal fired power stations and more hydropower.

GHD’s Santiago office is playing a major role in the development of new power projects in Chile and nearby Peru with significant roles in environmental permitting and project development. One of these roles is Owner’s Engineer to Colbun for the development of a 350MW coal fired power station.

Two new 140MW gas-fired cogeneration units in Western Australia were the latest projects delivered through GHD’s long relationship with leading energy infrastructure company Alinta.

The cogeneration plants deliver more than 75 percent energy efficiency, compared with 25-50 per cent for other power plants operating in Western Australia. The recently completed cogeneration units are located within Alcoa’s Pinjarra Alumina refinery in the south-west of Western Australia. The combined output of the units is 280MW of power, and up to 840tph of steam.

Located off the grid in a remote part of the County, the school generates its electricity with two old, oversized diesel generators. GHD was engaged to find a solution to reduce costs and improve reliability while incorporating renewable energy.

We assisted the School Board in obtaining funding and designing a diesel battery hybrid system that is “plug and play” ready for the addition of photovoltaic panels pending additional funding.

The Humboldt Bay Power Plant, which was the first nuclear reactor ever built in California, has been out of commission for several years. Pacific Gas and Electric Company (PG&E) has begun the dismantling process and is removing the diesel and natural gas generator units to make way for a new power plant.

GHD is providing the structural engineering for the dismantling of the fossil fuel portion of the plant as well as performing the lead and asbestos surveys for the demolition. Our structural engineers are developing plans for the rigging and removal of the fuel rod rack from the containment pool to allow PG&E to remove any nuclear fuel remnants. To aid in the dismantling, we are designing access roads, which may also lead to the site design for the new power plant.

The Headquarters Joint Operational Command (HQJOC) project is a signature project for the Department of Defence. It is both its first public-private-partnership project and the nerve centre for a new way of doing business, the Joint Operations Command.

GHD’s project management and technical adviser roles have ensured that Defence will be provided with a new facility that meets environmental objectives and is a state-of-the-art command and control centre.
