WP / 11 SFIThe SFI Group System: a functional classification for ship technical data, its limits and its future
An in-depth analysis of the SFI Group System: its origins and design principles, the theory of functional classification behind it, how it compares with SWBS, IEC 81346, ISO 14224 and ISO 19848, its structural limitations, and a multi-aspect data model for using SFI in modern PMS, analytics and digital twins.

WP / 10 PERFORMANCEMaintenance as an efficiency lever: hull, propeller and engine performance under CII
How maintenance decisions drive fuel consumption and IMO carbon intensity ratings: measuring hull and propeller performance to ISO 19030, biofouling management under the IMO 2023 guidelines, performance-triggered cleaning and engine maintenance, and the PMS data that connects them.

WP / 09 KPIsMeasuring maintenance performance: KPIs that tell the truth about a ship's PMS
Which maintenance KPIs are worth tracking for ships, how to calculate them from PMS data, how to balance leading and lagging indicators, and how to stop the numbers from being gamed, with reference to EN 15341 and the BIMCO Shipping KPI standard.

WP / 08 DRY-DOCKDry-dock and renewal survey planning: using the PMS to build a better dock
How to plan dry-docks and class renewal surveys from PMS data: the survey cycle and statutory bottom-survey limits, building the repair specification from jobs and findings, procurement lead times, yard execution and the post-dock update that keeps the PMS true.

WP / 06 SPARESSpare parts optimisation for ships: criticality, demand patterns and stock levels
A quantitative approach to shipboard spare parts: classifying parts by criticality, value and demand pattern, forecasting from the PMS, setting reorder points and safety stock, handling slow movers and insurance spares, and measuring the result.

WP / 05 MASTER DATAEquipment hierarchies and master data for fleet-wide PMS analytics
How to structure PMS master data so maintenance can be compared and analysed across a fleet: functional locations versus physical assets, SFI and the ISO 14224 taxonomy, equipment classes and templates, failure coding, reliability metrics and data governance.

WP / 04 RCM & CBMBeyond fixed intervals: reliability-centred and condition-based maintenance in a ship PMS
How to move a ship's maintenance from fixed intervals towards reliability-centred and condition-based strategies: RCM decision logic, failure patterns, the P-F interval, choosing monitoring techniques, class credit and the data a PMS needs to support it.

WP / 02 INTERVALSRunning hours, calendar intervals and class: setting maintenance periodicities that hold up in audits
How to choose and manage maintenance intervals in a ship PMS so that the schedule reflects the machinery, satisfies class continuous survey and gives auditors and inspectors a consistent record.
