Shipping’s biggest efficiency gains are already onboard

Arnaud Dianoux, CEO of Opsealog, recently highlighted that the most significant efficiency gains for the global merchant fleet are already onboard, waiting to be unlocked. While charterers prioritize fuel consumption, shipowners face mounting pressure to meet emissions targets amid ongoing global supply chain disruptions. By leveraging existing data streams from onboard systems, operators can optimize voyage planning and engine performance. This strategic shift is essential for vessels navigating major hubs like Singapore or Rotterdam to maintain profitability in a volatile market.

The maritime industry is under intense scrutiny to comply with IMO 2023 regulations, specifically the Carbon Intensity Indicator (CII) and the Energy Efficiency Existing Ship Index (EEXI) mandated under MARPOL Annex VI. These requirements, integrated into the broader framework of the International Convention for the Prevention of Pollution from Ships, demand rigorous monitoring of fuel oil consumption. For compliance departments, failure to maintain these standards risks vessel rating downgrades, potentially limiting access to key ports and increasing operational costs under stringent classification society audits.

Chief engineers and second engineers must now transition from traditional maintenance schedules to data-driven performance monitoring. These rank groups are responsible for analyzing real-time fuel flow and engine load data to minimize waste. By adopting these digital workflows, engine room teams can ensure the vessel remains within its required CII rating, directly influencing the ship’s commercial viability and ensuring seamless adherence to evolving environmental standards during every voyage.
