KR (Korean Register) has issued a Statement of Fact for the Vessel Performance Calculation Methodology developed by ShipWatch, an affiliated company of Navig8 and ADNOC L&S. KR's technical review confirmed that the methodology aligns with the principles and performance-monitoring sequences established in the international standards ISO 15016:2015 and ISO 19030:2016.

The Statement of Fact was formally presented to ShipWatch on September 2 during SMM 2026 in Hamburg, Germany.

ShipWatch is a voyage execution and performance monitoring platform used across fleets operated by Navig8, ADNOC L&S, and other owners and charters across multiple vessel segments. The platform supports day-to-day operations, including real-time vessel tracking, data validation, charter party compliance monitoring, emissions reporting, and voyage optimization.

Standardized performance measurement has become a pressing concern in shipping as operators face tightening international rules on carbon intensity, including the IMO's Carbon Intensity Indicator (CII) and Energy Efficiency Existing Ship Index (EEXI), as well as regional schemes such as the EU Emissions Trading System, which was extended to maritime transport in 2024. Accurate, ISO-aligned speed loss and power deviation data underpins both regulatory reporting and charter party disputes, where performance claims often hinge on which methodology was used.

ISO 19030:2016 specifies methods for measuring changes in hull and propeller performance, while ISO 15016:2015 sets out the assessment of speed and power performance through speed trial analysis. Independent verification by a classification society such as KR — a full member of the International Association of Classification Societies (IACS) — provides third-party assurance that a platform's calculations follow these recognized standards rather than proprietary, unverifiable methods.

KR's technical review focused on three primary areas of the ShipWatch methodology: environmental data correction, performance indicator calculation, and the evaluation of changes in vessel performance.

The assessment verified that the software adheres to the core performance-monitoring sequences established in ISO 19030:2016. Its correction algorithms for environmental factors, including wind, waves, and seawater properties, were also found to align with the principles of ISO 15016:2015. KR further reviewed the methodology used to derive key performance indicators (KPIs), such as power deviation and speed loss, as well as its application of uncertainty analysis to daily noon report data.

Daeheon Kim, Executive Vice President of KR's R&D Division, said: "As the maritime industry accelerates its decarbonization and digitalization efforts, reliable and standardized vessel performance data is becoming increasingly important. Through our technical review, KR has confirmed that ShipWatch's methodology provides a consistent and reliable foundation for evaluating vessel performance in full alignment with international standards."

He added: "KR remains committed to supporting maritime stakeholders and digital platforms like ShipWatch as they respond to evolving regulatory requirements and advance data-driven vessel operations."
