Acoustic emission based condition monitoring study of piston rod seals by varying speed and pressure parameters
Shanbhag, Vignesh Vishnudas; Meyer, Thomas; Caspers, Leo; Schlanbusch, Rune (Peer reviewed; Journal article, 2020)Seal wear is one of the primitive causes of failure in hydraulic cylinders. Regular visual inspection of seals without affecting the productivity is difficult as the seals are placed internally in the hydraulic cylinder ... -
Acoustic Emission-Based Condition Monitoring and Remaining Useful Life Prediction of Hydraulic Cylinder Rod Seals
Pedersen, Jørgen. F.; Schlanbusch, Rune; Meyer, Thomas; Caspers, Leo. W.; Shanbhag, Vignesh Vishnudas (Peer reviewed; Journal article, 2021)The foremost reason for unscheduled maintenance of hydraulic cylinders in industry is caused by wear of the hydraulic seals. Therefore, condition monitoring and subsequent estimation of remaining useful life (RUL) methods ... -
Automated and Rapid Seal Wear Classification Based on Acoustic Emission and Support Vector Machine
Kandukuri, Surya Teja; Shanbhag, Vignesh Vishnudas; Meyer, Thomas; Caspers, Leo; Noori, Nadia; Schlanbusch, Rune (Journal article; Peer reviewed, 2021)Seal wear in hydraulic cylinders results in fluid leakage, and instability of the piston rod movement. Therefore, regular inspection of seals is required using automated approaches to improve productivity and to reduce ... -
Condition monitoring and maintenance for fibre rope moorings in offshore wind
Nordgård-Hansen, Ellen Marie; Schlanbusch, Rune (Research report, 2023)The FIRM project aims to develop innovative mooring systems for floating wind farms based on fibre ropes, including new and more efficient methods for installation, condition monitoring, maintenance, and decommissioning. ... -
Condition monitoring of hydraulic cylinder seals using acoustic emissions
Shanbhag, Vignesh Vishnudas; Meyer, Thomas; Schlanbusch, Rune; Caspers, Leo (Peer reviewed; Journal article, 2020)In recent years, there has been a growing concern for fluid spill from hydraulic cylinders in the offshore oil and gas industry. To diagnose the leakage from hydraulic cylinders, there have been attempts made in literature ... -
Defining acoustic emission-based condition monitoring indicators for monitoring piston rod seal and bearing wear in hydraulic cylinders
Shanbhag, Vignesh Vishnudas; Meyer, Thomas; Caspers, Leo; Schlanbusch, Rune (Peer reviewed; Journal article, 2021)Fluid leakage from hydraulic cylinders is a major concern for the offshore industries as it directly affects hydraulic cylinder energy efficiency and causes environmental contamination. There have been attempts made in ... -
Diagnostics of seal and rod degradation in hydraulic cylinders using acoustic emissions
Shanbhag, Vignesh Vishnudas; Meyer, Thomas; Caspers, Leo; Schlanbusch, Rune (Peer reviewed; Journal article, 2020)External leakage from hydraulic cylinders is of a major concern for the offshore oil and gas industry. This occurs mainly as a result of physical damage to the piston rod or due to degradation of the piston rod seals. ... -
Forecasting Piston Rod Seal Failure Based on Acoustic Emission Features in ARIMA Model
Pedersen, Jørgen Fone; Schlanbusch, Rune; Shanbhag, Vignesh Vishnudas (Peer reviewed; Journal article, 2022)Fluid leakage due to piston rod seal failure in hydraulic cylinders results in unscheduled maintenance, machine downtime and loss of productivity. Therefore, it is vital to understand the piston rod seal failure at initial ... -
Sensitivity analysis for multi-measurement points based SHM in the mooring lines of floating offshore wind turbines
Sakaris, Christos; Anastasiadis, Nikolaos; Schlanbusch, Rune; Kandukuri, Surya Teja (Peer reviewed; Journal article, 2024)Structural health monitoring in floating offshore wind turbines' mooring lines is vital for detecting early faults and preventing disruptions. Currently, sporadic and expensive monitoring is conducted via remote-operating ... -
Subsea Motion Compensator – Scaled Test at Sea
Schlanbusch, Rune; Kandukuri, Surya T. (Research report, 2024)NORCE has analysed motion data collected from a scaled down version of an offshore floating wind substructure anchored outside Mandal, Norway. The purpose of the test was to demonstrate the effectiveness of a motion ... -
Vibration-Based SHM in the Synthetic Mooring Lines of the Semisubmersible OO-Star Wind Floater under Varying Environmental and Operational Conditions
Anastasiadis, Nikolaos; Sakaris, Christos; Schlanbusch, Rune; Sakellariou, John (Peer reviewed; Journal article, 2024)As the industry transitions toward Floating Offshore Wind Turbines (FOWT) in greater depths, conventional chain mooring lines become impractical, prompting the adoption of synthetic fiber ropes. Despite their advantages, ...
