Hull Stress Monitoring System – Installation and Commissioning
◆Hull Stress Monitoring System (HSM) Installation, Commissioning & Maintenance Services Operating vessels safely and cost-effectively requires accurate knowledge of ship design and an understanding of operational risks and their impacts. One challenge is the lack of information on actual loads on the hull at the Navigation Bridge. Previously, this problem relied on the judgment and experience of the navigator, but this technology allows for the acquisition of live data during voyages via the SENSFIB Hull™ Hull Stress Monitoring Solution. By monitoring the stress response of the hull structure during operation, it provides navigators with online information on load margins, supporting their decision-making. Features of the Hull Stress Monitoring System (HSM)： The sensor employs a Fiber Bragg Grating Sensor (FBG) for highly accurate measurements. Welding is not required for sensor installation, allowing for installation in hazardous areas. The sensors have IP68 waterproofing and can be completely waterproofed by applying epoxy resin adhesive, allowing for installation on upper decks and inside ballast tanks. By analyzing the collected data, it is possible to determine the necessity of inspections by classification societies and surveyors, reduce costs, and determine the service life. If fatigue data is obtained, it can also lead to life extension assessments, improving the durability of the vessel and aiding in the development of effective maintenance schedules and repair plans. If abnormal stress or fatigue is detected, appropriate measures can be taken to prevent accidents and damage to the vessel. We have obtained the ABS classification society’s SMART (SHM) Tier 3 Product Design Assessment (PDA) certificate. HSMs are also installed for applications such as sloshing monitoring of LNG fuel tanks and ice road monitoring on ICE-class vessels.
