Abstract

Classification survey requirements are anchored on the concept of a periodic, time-based preventive maintenance regime. The underlying principle of the periodic maintenance philosophy is that parts and components of equipment, machinery, systems and structures eventually wear out, thus the safety and reliability of parts and components – indeed the entire vessel – are directly correlated with time and operational age. While development of techniques and technologies have continuously improved surveys and inspection, the periodic maintenance philosophy has been the de-facto standard in marine and offshore industries for many decades.

This paper presents Lloyd Register’s Cyber condition based maintenance (CBM) technique: a scalable evaluation of components, equipment, machinery, systems and structures that detects their emergent faults, and characterises their progression to failure. This is an important step in the evolution of in-service classification:moving away from a periodic, time-based maintenance regime into an intelligent, real-time and predictive vessel health maintenance regime.

Keywords: data acquisition, data-driven techniques, data processing, diagnostics, edge computing, in-service classification, physics of failures techniques, prognostics, reliability based techniques, sensors.

Joseph Morelos is part of Lloyd’s Register Marine and Offshore Innovation team and has 15 years’ experience in the maritime industry. Currently dedicated to understanding novel, agnostic technologies and their practical applications in the marine industry, Joseph has dealt with a variety of new building projects including cruise ships, gas fuelled vessels, liquefied natural gas (LNG) tankers, naval vessels and passenger ferries. His last role was Lead Technical Specialist for engineering systems, which focused on the safe deployment of LNG to use as a marine fuel and the application of safe return to port principles in large passenger ferries and cruise ships. He has also represented LR in IACS working groups involving LNG and the use of gas as a marine fuel. He holds a BSc in mechanical engineering from the University of the Philippines and training from the Institution of Gas Engineers and Managers.
