Obana Systems Delivery
Integrated Control & Monitoring Systems & Fibre Distribution for an Innovative Heavy Lift Jack-Up Vessel
Monitor Systems is proud to have successfully delivered a full suite of control, monitoring, safety, and fibre optic communication systems to the OBANA — a self-elevating, heavy lift jack-up vessel engineered by merging two repurposed rigs with a newly constructed mid-section, complete with a 2,000-tonne crane.
This was a multi-phase delivery, combining complex system integration with offshore deployment. The project showcases Monitor Systems' capabilities in delivering bespoke automation and safety solutions for major offshore assets.
Preload Control, Tank Gauging & Watertight Door Monitoring
This scope involved the expansion and integration of systems critical to vessel stability, and watertight integrity. Highlights included:
- Siemens S7-1500 PLC
- Custom-designed Control Centre with 24” touchscreen IPCs
- Multiple remote I/O enclosures
- Pre-built liquid level computer enclosures
- Draft and air gap monitoring sensors
- Distributed remote HMIs and LED indicator panels
- Total: ~1,800 I/O points
ESD / Alarm System
The Emergency Shutdown and Alarm system was deployed across 27 different locations throughout the vessel. To reduce installation time and minimise additional works, the new I/O was integrated into existing enclosures — eliminating the need to re-gland and terminate a large volume of field cabling.
- Redundant Siemens S7-1500 PLCs
- Redundant SCADA servers with multiple clients
- Components distributed on opposite sides of the vessel with high-speed fibre
- Total: ~1,900 I/O points
Fibre Backbone Distribution
To support the scale and redundancy required for this platform, Monitor Systems supplied the distribution equipment for a 48-core fibre optic backbone, ensuring high-speed and high-integrity communications between all distributed systems.
- 6 equipment racks, each fitted with 6 fibre patch panels
- 38 third-party fibre termination boxes
- Total of 1,728 pigtails and 576 patch leads — fully tested and certified
Delivering Confidence Through Integration
This project reflects Monitor Systems' ability to deliver complete, high-performance solutions in demanding offshore environments. From design and build through to installation and commissioning, every system was engineered to maximise safety, operability, and maintainability.
Our integrated approach to automation, control, and communication ensures each project is tailored to the operational needs of the vessel and the technical requirements of the client.
