According to our latest market study on “Tunnel Boring Machine Forecast to 2027 – COVID-19 Impact and Global Analysis – by Type (Slurry TBM, Earth Pressure Balance Shield TBM, Open Gripper TBM, Shielded TBM, Multi-Mode TBM, and Other Types), Geology (Soft Ground, Hard Rock Ground, Variable Ground, and Heterogeneous Ground), and End-User (Transportation, Metals & Mining, Oil & Gas, and Other End-Users),” the market was valued at US$  6,236.13 million in 2019 and is projected to reach US$ 9,434.24 million by 2027; it is expected to grow at a CAGR of 5.7% from 2020 to 2027.

APAC Tunnel Boring Machine Market to Grow at Highest CAGR during Forecast Period

The market in APAC has been analyzed based on historical, current, and future trends across the region. It is the fastest-growing region as the market players are experiencing significant demand for their products due to constant development in transportation infrastructure, and road and rail infrastructure across the region. China and Japan are the leading countries in the APAC tunnel boring machine market owing to the rapidly rising government investments in the development of road and rail line infrastructure, including the construction of various tunnels in the route. In India, Delhi Metro Rail Corporation entrusted offering a Mass Rapid Transportation System (MRTS) network to Delhi City. For the underground network, the tunnels were constructed by slurry type shield machine. In the next phase of the project, the railway station used 14 tunnel boring machines to construct a tunnel with a diameter of 5.8 meters. During the project, as per geology parameters, the tunnel boring machines of Mitsubishi, M/s Herenknecht, and Kawasaki were selected. 

The growth outlook of tunnel boring machines market in all the major regions is estimated to be quite positive during the forecast period. However, due to the COVID-19 outbreak, all the major countries in regions such as North America, Europe, and APAC imposed strict restrictions on business activities and movement of goods and people. All these factors hindered both supply of and demand for tunnel boring machines, thus, restrained the revenue growth of the global market in 2020, which is likely to continue till mid-2021.

Key findings of study:

Technological developments are of greater use in tunnel construction since they allow easy access to construction in any ground conditions. Innovative monitors and sensors placed in the tunnel boring machines help in the smooth functioning of machines while excavating. Large diameter tunnel projects for transport infrastructures have influenced the research and development in tunnel boring machine design. Advanced machines can cope with mixed rock/ground conditions and change their operational mode depending on ground conditions. Large machines with diameters ranging from 14 to 17 meters have been manufactured and utilized across the world. Innovative technologies are being developed in various countries to treat the ground ahead of the machine and control the groundwater inflows.

Variable density tunnel boring machines is a next-gen multimodal machine used for soft soils. Without significant mechanical adaptations, variable density machines merge the basic technologies of enclosed soft ground tunnel boring machines, maintaining control of pressure on the face. These machines are used as a slurry pressure tunnel boring machine using an air bubble system in order to control face pressure and an earth balance pressure mode. Lately, these machines have been deployed for various major projects since they have the ability to work in different ground conditions. For instance, in May 2020, For the HS2 project, the UK’s variable density tunnel boring machines were used to help overcome the ground condition challenges. These advanced machines have been used on Ulm railway project, Germany; the Hallandsas rail tunnel, Sweden; and the Kland Valley MRT project, Malaysia.
