Inertial Labs has announced that all products in its MRU (Motion Reference Unit) line have been granted a Tier-2 Product Design Assessment (PDA) Certificate by the American Bureau of Shipping (ABS). Through technical evaluation of the Inertial Labs MRU products, representatives of ABS assessed the related assembly drawings, designs, datasheets and other assets, and issued a Tier-2 PDA Certificate (Serial number 19-HS1851412-PDA) for all members of the product line.
This PDA ensures that the products do not require Unit Certification to be installed on ABS classed vessels, MODU or facilities which are in existence or under contract for construction on the date of the ABS Rules and Specifications used for the evaluation. Furthermore, by determining Pitch & Roll, Heave, Sway, Surge, Accelerations, Angular rates, Heading, Velocity and Positions, the Inertial Labs MRU products are recognized as suitable for use with Dynamic Positioning Systems (DPS-1, DPS-2, DPS-3). According to the PDA, performance of the models reaches 0.05 meters Heave Accuracy and 0.02 degree Pitch & Roll Accuracy through an Operating Temperature range from -40 °C to 70 °C.
The Inertial Labs MRU product line includes four distinct models to cover a wide range of marine and offshore applications: Basic (MRU-B), Enhanced (MRU-E), Professional (MRU-P), and Survey Set (MRU-PD). Utilizing state-of-the-art algorithms and MEMS sensors, Inertial Labs MRUs are used for real-time, high frequency measurements of manned and unmanned surface vessels (USVs), Remotely Operated Vehicles (ROVs), unmanned underwater vehicles (UUVs), marine antennas, and more.
The American Bureau of Shipping (ABS) is one of the largest maritime classification societies with a fleet of over 12,000 commercial vessels and offshore facilities. Its core mission is to promote the security of life, property and the natural environment, primarily through the development and verification of standards for the design, construction and operational maintenance of marine and offshore assets. It develops standards and technical specifications, known collectively as the ABS Rules & Guides. These Rules form the basis for assessing the design, construction and integrity of new and existing vessels, marine technologies and marine structures.
