The issue of effective gas drying becomes especially significant due to the increasing demand for LNG, driven by the energy transition and environmental requirements. Deep adsorption drying is necessary to prevent equipment corrosion, hydrate formation, and to enhance the overall efficiency of production. Improving drying methods and using highly efficient adsorbents contribute to increased reliability and reduced costs in LNG production.
Using modern scientific approaches and laboratory equipment, the main characteristics of adsorbents necessary for assessing their suitability for use in real production processes were investigated.
Patterns of the influence of chemical composition, pore size, and thermal regimes on the ability of adsorbents to retain moisture and remove it from natural gas were identified.
One of the most important conclusions of the study is the confirmation of the competitiveness of adsorbents produced in Russia compared to foreign analogs, in some cases demonstrating better performance.
The results obtained are of significant interest to the scientific community, engineering technologists, and managers of enterprises involved in LNG production, as they provide a scientific basis for the modernization of existing facilities and the design of new complexes.
For each round trip (laden and ballast), PEARL-LNG-RO solves interconnected boil-off, heel management, and propulsion equations across five engine families (Steam, DFDE, X-DF, ME-GI, and STaGE), allocates fuel between main and auxiliary, and prices consumption using monthly HFO/ MDO and LNG indices (Brent, TTF, Henry Hub, and JKM). The 2022 calibration covers 5,642 laden voyages (≈ 370 Mt delivered) linking ~1,200 export–import pairs. The volume-weighted mean port-to-port freight is $ 2.49/MMBtu (5th–95th percentile: $ 0.59–6.88/MMBtu), with cost shares: charter 64%, fuel 25%, ports 5.1%, operations 5.6%, and canals 1.3%. Route contrasts are large: US Gulf Coast to Northeast Asia via Panama averages 4.76 USD/MMBtu, whereas Intra-Mediterranean averages 1.84 USD MMBtu⁻¹ both including charter.
Applying the optimization to observed spot voyages (N = 1,647; ~104 Mt) reduces the energy-weighted average freight from $2.86 to $1.66/MMBtu (−42%) by reallocating flows among feasible terminal pairs within lean/rich density classes. This provides a quantitative upper bound on savings available from coordinated charter strategy and routing, subject to real-world constraints (contracts, berthing windows, boil-off limits). From our companion Global LNG supply chain analysis, route/engine heterogeneity yields 0.80–1.9 g CO₂e/MJ. Under an output-based levy at $100/t-CO₂, the incremental cost adds ≈$0.50/MMBtu to typical voyages.
The open-source codebase and calibrated dataset enable voyage-level benchmarking and charter-strategy optimization when paired with life-cycle emissions assessment from our companion study; they can inform cost-and carbon-aware routing decisions across trading basins.
Located offshore Jakarta, the FSRU terminal regasifies LNG for power plant consumption while managing increasing operational complexities, including fluctuating demand, multiple LNG suppliers, and co-mingled cargoes. Structured operational excellence programs have been implemented, including robust frameworks for process safety, reliability engineering, and performance monitoring to ensure uninterrupted gas delivery.
This abstract outlines the strategic approach and innovative practices applied to maintain operational reliability. It explores key challenges and the corresponding solutions, including the adoption of digital transformation, workforce upskilling, and adherence to evolving regulatory requirements. The use of digital tools—such as real-time analytics, predictive maintenance, and remote monitoring—has strengthened operational agility and enhanced resilience against disruptions stemming from geopolitical events, extreme weather, or market volatility.
Aligned with Indonesia’s roadmap toward Net Zero Emissions (NZE) by 2060 and the United Nations Sustainable Development Goals (SDGs), the FSRU infrastructure supports clean energy access (SDG 7), resilient infrastructure (SDG 9), and climate action (SDG 13). By maintaining high operational standards and fostering collaboration across stakeholders, this model offers a scalable approach to LNG midstream operations that supports both national development and global sustainability objectives.
This case provides practical insights into how operational excellence in LNG infrastructure can enable a reliable and resilient transitional pathway in the evolving global energy landscape.
