Engineering fully automated BWTS system for unmanned offshore platform

Year:

2025

Vessel type:

Tension Leg Platform

Class:

DNV

SOW:

Turnkey engineering, automation software development, equipment supply, and installation support for ballast system.

  • 10

    Installation days

  • 6

    Team members

  • 2

    Ballast pumps installed

  • 5+

    Years of operation without major overhaul

CLIENT CONTEXT:

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:

  • 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.

BRIEF

The work to be done

Project Phases

  1. Develop a complete engineering package covering ballast, ventilation, and tank instrumentation systems, including detailed 3D modeling and execution drawings.
  2. Design and approve all mechanical foundations and structural supports.
  3. Supply pumps, valves, filters, sensors, and electrical components.
  4. Implement full automation software and integrate remote control capabilities.
  5. Support installation with supervision as required by the client.
  6. Perform system testing, calibration, and documentation approval with classification society DNV.
