Since early 1980, BP has been developing the conceptual design of a Single-Well Oil Production System or SWOPS. This paper outlines the concept and discusses the design and the operational criteria that have been applied in this early work. It further examines some of the innovative areas of technology that have been included in this new approach and outlines the work of the detail design phase, which has just started.

Mass Balancing

Presses with mechanical linkages based on levers between motor and ram (path-linked presses) tend to oscillate due to inertial forces as a consequence of the drive parts motion.In this publication a new approach for a mass-balancing system is presented. This system allows to generate the optimal compensation forces needed to counteract the inertial forces by means of four linear motors. The control signals for the linear motors are specified by an evolutionary optimization algorithm, which operates on the base of measured accelerations of the press frame. The control signals of the linear motors are created in a way that the machines oscillations are reduced to a minimum. This way the presented mass-balancing system adapts itself automatically to varying conditions during the operation of the machine, such as a tool change or a varying stroke rate.In particular, the present publication provides the results of the conceptual design and the virtual testing of this approach, which has been mainly carried out with the help of multiple-body simulations.

Aircraft Conceptual Design

Nowadays, all the stakeholders, policy makers, regulators, aircraft designers, producers, operators, etc.) are intensively working on development of the aircraft with full electric and hybrid propulsion systems. However, the technical, technological constrains (like limit on accumulator energy density) require introducing a new approach to conceptual design of such aircraft. The new methods is based on energy and mass balance evaluation. This paper analyses the identified constrains; integrates the energy and mass balance equations into the preliminary definition and calculations of the aircraft performance. By this way, the technological constrains might be transferred into the limitation on the aircraft energy and mass breakdown, that initiates a new approach to aircraft conceptual design uses the knowledge based multidisciplinary optimization. The paper describes the developed methodology for conceptual design of aircraft. It show results of implementing this new development philosophy to conceptual design of a four-seat small electric/hybrid aircraft and a special hybrid cargo UAV. The discussion of the results including got by using the emerging and enabling new technologies and new methods and solutions (including for example distributed propulsion system, unconventional forms, morphing, biomimics, etc.), demonstrates the possible implementation of the new development philosophy, new approach to aircraft conceptual design.

Simulation And Evaluation

Business networking strategies and especially co-operation in logistics is gaining momentum for individual companies in order to survive in competitive markets. As cross-company transport bundling is a powerful approach to optimize cost structures, this publication deals with the conceptual design and evaluation of cross-company logistics models. For this purpose, a simulation and evaluation model is presented that supports the development of new logistics concepts. Therefore models for the calculation of emissions, costs and logistics competitiveness, have to be created and combined to holistically validate and evaluate the new approach. This combination between the three different target values distinguishes the developed model from already published methods. Based on the sustainable, company-wide approach, potentials for optimization in the areas emissions, costs, and logistic competitiveness can be detected and by means of these analysis results, new sustainable and energy efficient logistics models can be designed.
