Core Services

Our dredging fleet consistently delivers high-performance results across Indonesian waters, serving both public and private sectors with precision, safety, and reliability. Backed by advanced equipment, skilled personnel, and proven operational standards, we execute complex dredging projects that support critical maritime infrastructure development nationwide.

We offer specialized dredging services tailored to the needs of port authorities, developers, and coastal engineers. Our core capabilities include:

Deepening and Widening of Access Channels, Berthing Places, Docks, and Turning Basins
Enhancing navigational access for larger vessels and port expansion.

Dredging of Rock or Sand Banks in Open Sea
Clearing offshore obstructions to ensure safe maritime passage.

Maintenance Dredging in Existing Ports and Waterways
Preserving depth and functionality through routine or on-demand dredging.

Creation of New Port Access Channels
Developing new navigational routes for greenfield port projects.

With a strong project portfolio, compliance with international standards, and a focus on environmental responsibility, we are a reliable partner for sustainable marine development.
Our marine construction services offer a full spectrum of engineering solutions to support resilient and sustainable coastal infrastructure. With a focus on quality, safety, and environmental responsibility, we deliver end-to-end construction works tailored to coastal and port development needs.

Our key capabilities include:

Coastal Defences & Breakwaters
Construction of rubble mound and vertical/sheet pile structures to protect shorelines and harbor assets.

Trestle & Seawall Construction
Development of durable structures to ensure safe marine access and shoreline stability.

Port Construction
Piling, bracketing, and other structural works to support terminal expansion and modernization.

Land Clearing & Filling
Coastal and reclaimed land preparation through clearing, grading, and engineered fill placement.

Soil Improvement
Ground enhancement techniques to improve load-bearing capacity and stability.

Concrete Coastal Structures
Construction of docks, jetties, and mooring dolphins to support port operations.

All projects are backed by detailed studies, including wave climate analysis, storm surge forecasting, and hydrodynamic modeling, ensuring structural integrity and reliable performance under diverse marine conditions.

We help turn underused areas into valuable land through our innovative reclamation projects. Whether for homes, businesses, or public spaces, we transform low potential land into ready to use sites. Using modern vessels and smart techniques, we make sure every project is cost effective and environmentally friendly. You can count on us to deliver great results while protecting nature.
Bathymetric surveys help map the shape of the sea floor and measure water depth. They are important for marine construction, dredging, and navigation projects. We use modern technology that combines detailed sonar systems with GNSS satellite positioning to collect accurate, real-time data about the seabed. This allows us to provide reliable information that supports safe operations and better planning for maritime development.
