Process Integration and System Analysis for Seawater Cooling in Industrial Facilities

Two approaches to decision-making for ensuring the safety of an industrial facility are considered: safety requirements have been defined by normative documents and are controlled by the state; safety requirements are accepted by those who create and operate a hazardous object based on its system analysis and risk assessment. Has been performed the system analysis together with determining an impact on the risk of some decisions, regulated by normative documents. It has been shown that these decisions practically do not influence the technological system’s risk and safety, and expenses for their implementation are unjustified. Decisions based on the technological system’s danger analysis with subsequent choice of systems fulfilling safety functions, and requirements for their efficiency and reliability, ensuring a risk reduction to acceptable values, allow ensure safety as the absence of unacceptable risk with optimization of expenses for the safety achieving.

Recent Developments

Energy is a fundamental element supporting societal development, particularly with the increasing dependency on the Internet of Things. It is also the main contributor to environmental impacts and subsequently, a potential sector for mitigation. Sustainable energy system design considers energy savings and energy efficiency, waste and consumption reduction, process efficiency enhancement, waste heat recovery, and integration of renewable energy. Emerging tools range from advanced Process Integration, modelling, simulation, and optimisation, to system analysis and assessment. This review covers selected emerging studies promoting sustainable system design, including the recent developments reported in the Special Issue (SI) of the 22nd Conference on Process Integration, Modelling and Optimisation for Energy Saving and Pollution Reduction (PRES’19). The primary emphasis was to enhance the economic and environmental performance. However, social factors were also highlighted as essential for future sustainable development. The discussion and analysis in this review focus on the most recent developments of (a) heat integration and heat transfer; (b) integrated and newly developed heat exchangers, (c) integration of renewables, and (d) roles in economic and environmental sustainability. The key results are highlighted, and future research ideas are suggested according to their links to a broader context.

Object and purpose of research. This paper discusses current international regulations governing man-made noise in marine environment. Systematization of normative documents issued by a number of international classification societies, as well as of the documents released by the international organization dealing with life safety of marine ecosystems highlighted the necessity for the Russian Federation to develop a similar regulatory basis of its own. This paper is a review of international standards and rules for man-made underwater noise, as well as of current international programs dealing with research, regulation and control of man-made underwater noise. Materials and methods. This paper is based on KSRC-developed methodical materials, international standards for underwater noise, as well as available publications in this sphere, both Russian and foreign. The study followed the methods of system analysis. Main results. Systematization of the data on current regulations for underwater noise of various ships, like cargo carriers, research vessels, seismic survey ships and fishing craft. The study concludes that Russia needs a similar regulatory basis that would cover offshore drilling rigs (both wildcat and production), underwater mining systems and subsea pipelines, large ships with high ice class, icebreakers and icebreaker-led caravans, as well as port infrastructure along Northern Sea Route lanes. Conclusion. To develop its own regulatory basis intended to set out the rules for man-made underwater noise, Russia needs a wide-scale systematic research campaign that would tackle the sources of man-made underwater noise at each lifecycle stage of any marine technology. This systematic research would pave way to a scientifically justified regulations for underwater noise of marine industrial facilities, shipping and port infrastructure.
