Highlights

Set to become one of the largest CCS projects in the world
Expected to reduce carbon dioxide volume emitted via flaring by 3.3 MT CO2e per annum
McDermott’s first CCS project in Asia

McDermott is performing the transportation and structural installation of a 138-kilometer (85 miles) pipeline section, a 15,000 metric tonne (MT) CCS platform jacket, and a bridge connecting to the existing central processing platform in the Kasawari gas development field.

KG-DWN-98/2 Subsea Development

984 to 4,921 feet

water depth

5 locations

engineering executed

Highlights

India's largest integrated subsea development
Executing the engineering, procurement, construction, installation, and pre-commissioning of subsea umbilicals, risers and flowlines (SURF) at water depths between 984 feet (300 meters) and 4,921 feet (1,500 meters)
When completed the project is expected to contribute 7% to the country's overall natural gas output following the start of hydrocarbon production in its KG-DWN-98/2 block - a major boost to energy security

The integrated subsea package includes the supply of all subsea production systems (SPS), including deepwater trees, and the installation of pipelines, subsea umbilicals, risers and flowlines (SURF). First gas was achieved in March 2020, followed by the completion of the partial gas system in September 2021. In January 2024, first oil was also achieved.

Highlights

One of the world’s largest subsea gas fields developments
Delivered engineering, procurement, construction, installation and pre-commissioning of 140 km of infield pipeline, risers, umbilicals, MEG injection systems, 26,000 MT of subsea structures, hooked up to the world’s largest semi-submersible central processing facility in seismically active zones with conditions of sour service
Currently executing the engineering procurement and construction of a 3x33% dedicated compression train with 2,900 tonnes lower module and 1,900 tonnes upper module
When complete, this development is expected to bring more efficient and reliable access to natural gas for the Asia-Oceanic region

The Ichthys LNG is ranked among the most significant oil and gas projects in the world. Located about 136 miles (220 kilometers) offshore Western Australia, it lies in an average water depth of 820 feet (250 meters). The Ichthys field is estimated to contain more than 12 trillion cubic feet of gas and 500 million barrels of condensate.
