Unlock Significant Energy Savings with SAJ-DMS & ODT
Today’s energy management strategies for vessels primarily focus on monitoring engine performance, optimizing routes, and adapting to weather conditions. However, a crucial yet often overlooked parameter is the vessel’s hydrodynamic condition. When managed accurately, this factor unlocks considerable energy savings.
SAJ Instrument has developed a groundbreaking solution—SAJ-ODT, an advanced guidance software built upon the industry-leading SAJ-DMS system. The IMO’s MEPC guidance on “Best Practices for Energy-Efficient Ship and Fleet Operation” ranks comparing optimal trim to real measured trim as one of the most critical factors in energy efficiency. This underscores the necessity of an accurate dynamic measurement standard, a requirement for both retrofits and new builds.
The Issue with Outdated Trim Optimization Tools
Many shipowners invested in trim optimization solutions 6–10 years ago, such as the so-called “Dynamic Trim Support Tools.” These legacy systems lacked reliable measurement accuracy for trim, hull flexing, list, and draft, relying instead on power/speed regression analysis to estimate optimal trim. Unfortunately, their measurement inaccuracies negated potential savings, resulting in ineffective optimization.
With today’s stringent operational and regulatory demands, shipowners must upgrade to modern solutions that deliver real and measurable savings. SAJ-DMS & ODT provide the industry’s most accurate, real-time measurement-based trim optimization, ensuring maximum efficiency and ROI.
Why SAJ-DMS & ODT?
- Seamless Upgrade – If your vessel is already equipped with SAJ-DMS, it can be easily updated with SAJ-ODT, maximizing energy savings with minimal investment.
- Real-Time Guidance—Unlike outdated systems, SAJ-ODT is a hands-on guidance tool that continuously calculates and displays optimal trim based on actual vessel conditions.
- Unmatched Accuracy – SAJ’s system offers centimeter-level precision that aligns perfectly with hull scale markings, ensuring reliable optimization based on actual hydrodynamic conditions.
- Advanced Optimization Modes – SAJ-ODT operates in three modes:
- PORT (static optimization)
- SHALLOW (squat mitigation)
- DEEP (dynamic optimization)
- The system automatically detects conditions and adjusts optimization, accordingly, ensuring maximum efficiency in all environments.
- Proven Savings Potential – Studies confirm that traditional trim optimization methods predict energy savings of 1–8%. In contrast, SAJ’s direct-measurement approach provides greater accuracy, ensuring a significantly higher savings potential.
- Regulatory & Compliance Benefits – Trim optimization ranks highest in SEEMP guidance (MEPC.213(63)) under “Optimized Ship Handling.” It is also a fundamental part of a vessel’s Energy Efficiency Operational Indicator (EEOI).
- Essential for New Builds – Shipowners planning newbuild projects must specify modern, optimally designed measurement systems. SAJ-DMS utilizes a single hull intake, a draft transducer, and dedicated dynamic sensors—ensuring precise, real-time data essential for effective energy management.
