Costs of substantiating optimal layout solutions

What does the practice of modeling objects under construction show? Often, according to research results, the cost of protective structures exceeds the initial cost included in the feasibility study, which usually causes the displeasure of the design customer, who is trying to save money by reducing the parameters of protective structures. Obviously, ways to save money should be sought in non-traditional designs with lower material costs and lower labor costs. And here it is extremely necessary to use flat modeling in the hydroaract, which is also carried out at the Sochi VIS.

Contrary to the claims of the authors of the article, the costs of experimental substantiation of the parameters of fencing structures and optimal layout solutions in the process of spatial and planar modeling are insignificant and amount to a fraction of a percent of the cost of designing and building an object, usually not exceeding 100 thousand rubles.

In order to bring the modeling conditions as close as possible to full-scale ones, the best hydraulic laboratories in developed capitalist countries are equipped with equipment for generating wave spectra, the parameters of which correspond to full-scale ones using computer-controlled tracking systems. Unfortunately, the Sochi VIS cannot boast of such modern equipment. Obviously, in order to purchase and operate such equipment, it is necessary to increase the volume of operation of the station by 4-5 times. However, not all designers resort to the services of the station, considering the cost of modeling unnecessary, relying on their experience and specialization.

The following facts indicate how difficult the issue of designing port protection from unrest is: of the "Shelter or trap" mentioned in the article in some ports with protective structures, parking large-tonnage vessels in the ports of Poti and Tuapse is virtually impossible in case of tugboat phenomena, and vessels in such cases go out on an open raid. In the port of Ventspils, contrary to the claims of the authors of the article, the fencing structures no longer provide protection for the water area, which leads to the termination of cargo operations. This situation has developed in recent years as a result of significant deepening of the water area and the construction of new berths in the form of vertical walls, i.e. the expansion of the port took place without proper scientific recommendations.

Obviously, the construction and reconstruction of ports, including Odessa, should be based not only on calculations, but also on the results of studies of the wave regime on spatial models.

We fully share the opinion of the authors of the article that, if qualified specialists with many years of experience in the field of port engineering and a specialized material and technical base are available, the industry research program should include not only the reconstruction of existing and the development of new structures for fencing structures, but also the development of a unified research methodology and regulatory documents for hydraulic engineering. And the sooner this happens, the fewer financial losses there will be during the construction and operation of seaports.

Need a dry dock

Maritime transport is faced with the task of timely, high-quality and complete satisfaction of the transportation needs of the national economy and the population. Its solution depends to a large extent on the level of development of ship repair. However, the main tasks of the SRH: increasing production volumes, reducing ship repair time and improving its quality — are being solved slowly.
