The Implementation of Laser Shaft Alignment System on Rotating Machines in the Bulla Field, Platform 6

Shaft misalignment is a common fault in rotating machines in the industry. Inadequate coupling alignment of rotating shafts often results in serious vibration problems and premature machine component failure. This article introduces the concept of using a laser shaft alignment system to improve equipment reliability, maintenance efficiency, and reduce rotating component wear. This paper explores the concept of implementation of laser shaft alignment system on rotating machines in the Bulla field, Platform 6. For this purpose, an appropriate tool has been selected for further implementation. As compared to a traditional mechanical method, the proposed electronic approach has more accurate results and optimize the performance gained via the previous techniques. Additionally, the application of the proposed system is user friendly and faster compared to the previous method. The measurement procedure is issued as per system manufacturer recommendation, and manufacturer video training will be submitted to appropriate maintenance staff. The novelty of the approach is to increase the reliability of rotating machines on Platform 6 in the Bulla field and develop Company maintenance processes by implementing a new laser measurement system.

Vibration due to misalignment in the hydraulic pump is detected as the main problem of damage to the pump. Resolved a problem with the alignment of the pump, shaft alignment as an action in overcoming the problem. Vibration measurements are carried out during alignment and misalignment conditions by using a vibration measuring instrument, namely vibration analysis fluke 810. Voltage, current, electrical power, motor & pump rotation, and other operating parameters are observed. Vibration analysis is done by observing the velocity and frequency of the wave signal for alignment and misalignment conditions. Vibration analysis is performed using a comparison method to the ISO 10816-3 tester standard. Finally obtained an ideal vibration in the operation of hydraulic pumps based on the above standards.The method used to analyze using the tool RCFA (root cause failure analysis) which is an investigation process to determine the main causes of a failure mode. From the analysis, we concluded that the formulation RCFA rise broken of coupling.

Practical Aspects of Propulsion Shaft Alignment

The economical and operational implications of poor alignment are indisputable for the propulsion shafting system of a commercial vessel. This holds true for naval vessels as well, although far less documented in the technical literature. This paper addresses some of the challenges associated with the proper alignment of a high-speed naval craft, which has been in service for many years. Laser bore-sighting was performed on a Guided Missile Fast Patrol Boat resting on a docking cradle. The measured bearing offsets were input to a FEA model of the shafting system to calculate bearing reactions and detect potential misalignment issues. Subsequent decisions regarding corrective measures take into account the results computed by the numerical model, experience from sister ships, the available documentation from the building yard and several other factors which are discussed in the paper. The solutions proposed are targeted towards a balanced trade-off between cost effectiveness and out-of-service time on one hand, and the risk of potential damage from misalignment on the other hand, which would seriously disrupt the ship’s operational availability. Practical aspects and lessons identified in the process are also presented, which demonstrate the distinct differences in alignment strategy of a high-speed naval craft compared to a typical commercial vessel.
