CSR software updated

Common Structural Rules Software LLC, a joint venture company formed by ABS and Lloyd’s Register (LR), has released a software upgrade which aims to simplify compliance with current and pending IACS Common Structural Rules (CSR).

{mprestriction ids="1,2"}Version 2.5 of the CSR Prescriptive Analysis and CSR Finite Element (FE) Analysis software allows assessment of whole vessel structures – including new bulk carrier and oil tanker designs – using compliance information for the current CSR, which entered into force on 1 July 2015, as well as for the rule changes that come into force on 1 July 2018. Both class societies will use these tools to evaluate new designs against the CSR.

The updated CSR Prescriptive Analysis software can be used on both Windows 7 and Windows 10, and offers summary reports providing required and offered scantlings with a graphic representation of deficiencies. The reports summarise dominant criteria for each structure as well as data for every parameter value.

A new user interface for the CSR FE Analysis software has been added to enable automatic picking or manual selection to display the stress readout point for Cruciform Flange, Cruciform Web and Bracket Toe hotspots. Results are added to verification results for Fatigue Assessment.

“The Common Structural Rules provide the only industry route to compliance with IMO’s Goal-Based Standards for tanker and bulk carrier structures,” said LR Marine and Offshore Business director, Nick Brown.

“By working together, LR and ABS have provided fully up-to-date straightforward and accessible tools for the whole industry to use when applying CSR.”

The software is currently employed by approximately 1,600 users, with the updated CSR Prescriptive Analysis and CSR FE Analysis modules available for download from the Common Structural Rules Software LLC website.{/mprestriction}

  • LR and the National Physical Laboratory partner on marine autonomy assurance

    Lloyd's Register (LR) and the UK’s National Physical Laboratory (NPL) have teamed up to collaborate on marine autonomy projects to ensure that appropriate levels of service and competence can be achieved within the maritime industry.

    As part of the framework agreement, the two organisations will collectively establish and enhance the current body of knowledge for marine autonomy. This combination of skills, expertise and experience will be built on to bring clarity to the requirements for the assurance of autonomy and assist stakeholders in realising the potential of these systems in the market.

    This will allow standards to be set and consistently applied and will therefore bring surety to risk management and certification for autonomous and unmanned systems and vessels.

    By partnering with NPL, LR will enhance the delivery of its services and assurance in marine autonomy and gain access to a wide range of knowledge and expertise developed in other aligned domains.

    LR and NPL are currently working together to deliver a scope of services to the THEMIS Project, to demonstrate the feasibility for the world’s largest ocean-going autonomous vessel, which is part funded by the Maritime and Port Authority of Singapore’s (MPA) Maritime Innovation and Technology (MINT) fund.

    NPL’s head of Digital, Neil Stansfield, said: “The National Physical Laboratory (NPL) is excited by the opportunities presented in this collaboration with Lloyd’s Register, where the two organisations complementary capabilities are well suited to addressing the challenge of assuring marine autonomous systems. This work represents an important part of the UK’s national programme to deliver confidence in the intelligent and effective use of data, which is being conducted with a range of partners across sectors and with a specific focus on autonomous systems. NPL is applying a combination of measurement skills, expertise and experience, in areas as diverse as sensor characterisation, data quality and AI validation, to support partners in the development of new tests, standards and regulations for the safety of autonomous systems. This collaboration with Lloyd’s Register will help ensure the UK maintains its global leadership in the marine services Sector, where the autonomous shipping sector is expected to represent a global $52bn market opportunity by 2050.”

    Tim Kent, LR technical director for Marine and Offshore said: “This collaboration with the NPL will allow LR to improve our own processes, knowledge and competency to better support our clients with marine autonomy projects. We are delighted to be partnering with NPL given its domain knowledge on autonomy from the connected and autonomous vehicles (CAV) and unmanned aerial vehicle (UAV) domains.”
