ANNOTATION:

Modern information technologies make it possible to realize the proactive management of large offshore projects and find the best technical solutions during their design and operation. Therefore the LLC “Gazprom Neft Shelf” initiated the study on predictive analysis and risks prevention for “Prirazlomnoye” oil field. Project target was to increase the efficiency of transport system in front of plans to increase oil production from current 2.1 mln. t. per year up to 5 mln. t. in the year 2023. The article describes in detail the multidisciplinary simulation model of marine transport and support system for “Prirazlomnaya” oil production platform. The simulation model, developed in Krylov State Research Centre, includes the methods and tools from different scientific fields and allows capturing such features of investigated system as: environmental conditions dynamics at the platform allocation and at the vessel routes; dynamics of oil production; consumption of supplies at the platform and production of waste (back cargoes); operation of tankers and supply vessels. Model simulates the possibility of local reduction of oil production (in comparison with the planned values) due to unfavorable weather conditions and logistical difficulties. The original generator of marine weather parameters was created in this study. It permits to model the dynamics of 15 ambient factors like winds, currents and waves force and direction, ice concentration and drift, visibility conditions, etc. At each step of model time the possibility of cargo operations at four platform terminals is determined by means of special algorithm considering weather restrictions, individual features of each terminal and ship operational parameters. The description of vessels operating in the system was made with a high level of detail. Ship’s description includes the information about main design parameters, cargo spaces, propellers, loading conditions and equipment for cargo handling. Two projects of support vessels and one project of shuttle tanker were considered. Modeled platform needs are: transportation of oil, delivery of supplies and removal of waste. The estimated values of cargo flow cover the period up to the year 2038 and include: bulk materials, petroleum products, fresh water, oil recovery water, chemicals, equipment, products, solid domestic waste, industrial waste, pipe products and sludge. A special pseudo-optimal voyage planning algorithm was developed to generate ship schedule and determine vessel loading at each voyage in accordance with specified cargo flow. This schedule forms a basis to run the simulation model. Voyage planning algorithm takes into account a number of specific features of “Prirazlomnaya” platform and allows planning the joint operation of supply vessels and tankers. The results of model verification by means of the number of full-scale integral operational parameters are shown in the article. A number of alternative solutions to increase the transportation system efficiency are analyzed using the developed simulation model. Obtained results are relevant not only for “Prirazlomnaya” platform, but also for arctic offshore industry in general. The results of simulation are used as the basis for making the managerial decisions in LLC “Gazprom Neft Shelf” and modifying of platform technological documents.
