It is the responsibility of the user of this document to consider the applicable safety or operating practices recommended by regulatory agencies and organizations, to establish appropriate health and safety practices and to determine the applicability of regulatory limitations prior to use.
All electric components for the ship’s trim and list inclinometer installed in hazardous areas shall meet the requirements of IEC 60079-0 applicable for the specific zone within the hazardous area. They shall conform to the applicable sections of the national and/or international electrical safety standards and classification societies rules. Trim and list inclinometers shall be maintained in safe operating conditions in accordance with the manufacturers’ instructions.
The containment box includes a trim and list inclinometer and all the electrical and mechanical parts necessary for the installation and setup. The box shall be powered by electrical supply voltage and signal communication lines are included.
If the trim and list inclinometer is installed out of safety zones, the trim and list inclinometer and its associated devices, such as intrinsic safety (IS) isolators and anti-pressure explosion for signal, power supply and terminal units, shall be contained in a metal box in order to protect them from damage, heat and shock and to provide security.
A trim and list inclinometer system shall provide means to prevent unauthorized adjustment or tampering. Specifically, a trim and list inclinometer system used in custody transfer applications shall provide security to allow sealing of the calibration adjustment.
The security may include a physical seal. Once the trim and list inclinometer’s protection box has been sealed, it shall not be unsealed until the next scheduled calibration/inspection.
The accuracy of trim/list measurement by a trim and list inclinometer is affected by the inherent error of the trim and list inclinometer. The error can happen due to installation (for example, stability and location), interface error, the effect of changes in operating conditions, the ship’s motion and, most of all, the ship’s bending (hogging and sagging).ISO 19636 pdf free download.
