As a leader in the steel pipe industry, PT Steel Pipe Industry of Indonesia Tbk (SPINDO) continues to support strategic infrastructure development in Indonesia. One of the latest achievements is the successful early delivery for the PT PAL INDONESIA (PERSERO) project entitled “Procurement of Design & Build Services for Block A-B Submarine Dock Construction & Facilities”.

Steel Pipe Solution for Submarine Docks

The project utilizes steel pipe pile foundations specially designed by SPINDO with specifications:

• ASTM A252 Gr. 2
• Diameter: OD 812mm hingga OD 1016mm
• Equipped with Marine Epoxy Coating for protection against corrosion in maritime environment.

These pipes not only have high durability, but are also equipped with the latest joint technology, such as CC and CT Joint. This technology ensures structural stability and efficiency in installation to support the dock as a solid retaining wall construction.

Get to know CC and CT Joint

CC Joint dan CT Joint are important components in connecting steel pipe piles with precision. Here are their functions:

• CC Joint (Compression Connector Joint)
• Overcomes high compressive loads.
• Ensures the connection between pipes remains stable to support vertical and horizontal loads.
• CT Joint (Connector Tension Joint)
• Withstand stresses that arise during installation or use.
• Increase the durability of the structure against soil pressure and environmental loads.

With this technology, the pier structure is able to withstand ground shifts while ensuring long-term durability.

Advantages of Retaining Wall Construction Technology

The use of retaining walls in the Block A-B Submarine Pier brings a number of important benefits, including:

• Guaranteed Ground Stability

Pipe piles play a role in resisting soil pressure, maintaining the stability of the pier.

• Long-term Durability

Marine Epoxy Coating protects the pipes from corrosion, extending the life of the infrastructure.

• Project Efficiency

CC and CT Joint technology speeds up installation, saving construction time.

The Block A-B Submarine Pier Project is a major step in strengthening Indonesia's maritime and defense sectors. With SPINDO's participation, the project is expected to make a significant contribution to the development of national infrastructure.
