CLIENT CONTEXT
Remote ballast control for unmanned offshore asset
The client required a compact, fully automated ballast system for an unmanned offshore platform operating in Greek waters. With no crew onboard, the system needed to be remotely operated, highly reliable, and compliant with DNV and local regulatory standards — all while fitting within tight spatial and operational constraints.
THE CHALLENGE
Confined-space integration
Integrating all pumps, valves, filters, and electrical equipment in a compact, confined technical room below deck. Meeting strict redundancy and remote access requirements to ensure system reliability and minimal maintenance offshore. Coordinating mechanical, electrical, and automation engineering with equipment procurement and installation supervision.
THE WORK TO BE DONE
Project phases
Develop a complete engineering package covering ballast, ventilation, and tank instrumentation systems, including detailed 3D modeling and execution drawings. Design and approve all mechanical foundations and structural supports. Supply pumps, valves, filters, sensors, and electrical components. Implement full automation software and integrate remote control capabilities. Support installation with supervision as required by the client. Perform system testing, calibration, and documentation approval with classification society DNV.

PROJECT SOLUTION
Steps
01.

Engineering and 3D Modeling

Complete 3D modeling and detailed design of ballast, ventilation, and tank instrumentation systems, including collision checks and execution drawings. Prefabrication of equipment foundations, piping spools, valve supports, and seawater chesons.
02.

Installation of ballast pumps, valves, filters, and axial flow fan in the dedicated technical compartment below tank WB F2. Integration of piping and mechanical equipment according to design and foundation drawings.
03.

Mounting and wiring of ballast switchboard cabinet on the main deck for easy access. Connection of sensors, electric actuators, control panels, and full automation enabling remote monitoring and control.
04.

Hydrostatic pressure testing and air leak testing of piping and pneumatic systems. Calibration of level, pressure, and temperature sensors. Final inspection, approval by DNV, and delivery of complete installation documentation for client operation.
END OF DELIVERY
The outcomes
Final Results
  • Successful completion of the ballast system installation on the Tension Leg Platform within the scheduled timeframe, without impacting platform deployment.
  • Full compliance with DNV offshore unit regulations and Greek environmental requirements.
  • Zero safety incidents recorded during execution.
  • System delivered fully automated with remote control capabilities and ready for operation with no pending issues.
