Repeatability and robustness are the key factors that the automotive producers are demanding in connection with the crash performance of bumper beam systems. Bumper beam systems are important structures of an automotive that protect the passengers from front and rear collisions. Assessing the impact performance of only a bumper beam system through full-scale crash tests of a car is not easy. Thus, this paper presents experimental investigations on the bumper beam-longitudinal systems subjected to 40% offset impact. Bumper beam systems that are generally fitted to the automotives include 'crashboxes' besides the longitudinals. In the current study, the bumper beam system does not include any 'crashboxes'. This is also the preferred system for some automotive producers. A longitudinal will offer higher resistance to deformation and thus gives higher energy absorption than if crashboxes are used. Using SIMLab's kicking machine, experiments were performed on rotary stretch-bent aluminium bumper beams, which were connected to two longitudinals at both ends and an experimental database was established. The repeatability and robustness of the bumper beamlongitudinal systems were studied by varying the material and temper condition of the longitudinals. Experimental investigations revealed that the longitudinal members with considerable strain-hardening would change the collapse mode into a global mode and reduce the energy absorption capability, due to the random development of lobes along the length.

The paper presents the results from numerical simulations of bumper beam-longitudinal systems subjected to 40% offset impact loading. Numerical simulations were carried out with the non-linear finite element code LS-DYNA, searching for an efficient, numerically robust and accurate representation of the observed system behaviour. A comparative study of an industrial-like modelling procedure and another procedure incorporating a user-defined material model has been performed. In the latter procedure, the material model consists of state-of-the-art anisotropic plasticity, an isotropic strain and a strain-rate hardening rule as well as some ductile fracture criteria. Both shell and solid elements were utilized in discretizing the bumper beam-longitudinal set-up. Numerical crash results revealed good agreement with the experiments with respect to overall deformation mode and energy dissipation. The simulations were capable of giving relatively accurate prediction of the collapse mode found in the experimental tests, except for the bumper beam-longitudinal system with AA7003-T1 longitudinals. Sensitivity studies were performed considering both physical and numerical parameters. The physical parameters were strain-rate effects and the heat-affected zone, whereas the numerical parameter considered was adaptive meshing.

This article investigates the implementation of a tailored requirements management system. Requirements management is becoming increasingly important, due to the growing complexity of umbilical systems coupled with efforts to reduce both project duration and project cost. We have investigated the use of a new system for requirements engineering and management, by interviewing stakeholders and analyzing the as‐is state of the company. Based on the findings, this paper proposes a requirements template and tailored functionalities to aid with requirements engineering and management. Results indicate that the use of requirement elicitation increased by 62 % through implementation of the proposed system. A survey with stakeholders reveals that they are positive to future implementation of the proposed system. In conclusion, the tailored requirements management system will be a step in the right direction for management of requirements and better control for members of the project teams.

Engineering, Procurement, Construction and Installation (EPCI) projects for the offshore oil and gas industry become more and more complex, with a reduced timeframe, and increased demand for cost savings in the industry. The result is reduced profit margins; therefore, the need for increased productivity is higher than ever. Some of the aspects important for productivity include material flow, information flow, sound planning, and organizational structure. This paper focuses on the information transfer between the engineering team and the installation phase of the fabrication at AS Nymo. Feedback from stakeholders, previous research and lessons learned from completed projects pinpoints that this handover has a potential for improvement. We analyzed historical data and involved key stakeholders in an iterative process to identify insignificant elements in the handover format. By removing this insignificant information, we found that it is possible to reduce the number of handover revisions by 60%. Additionally, we found that improving the handover could give a 67% reduction in time spent for the receiving stakeholders to find the specific information they seek. To verify our results, we suggest further testing for verification before validation through a full‐scale project execution testing for future research.
