The project:

In 1991 Technital was commissioned by the Russian industrial Fisheries Consortium BPO Dalryba to develop the basic design for a bunkering station with related jetty, in the bay of Troiza, located in the Vladivostok region.

The design was accompanied by a study of the impact of the new installation on the environment and of the measures required to mitigate these effects.

Following collection and evaluation of the available data on the climate and the coastal hydrodynamics of the area, Technital first proceeded to reconstruct the local conditions of current circulation and wave motion by means of a series of simulations using a finite elements hydrodynamic model and a ray wave propagation model, the latter integrated by a simple model for calculating wave motion generated locally by wind action.

Once the elements for selecting the location and defining the design conditions for the new jetty had been obtained, the various possible locations for the sea effluent of polluted water, inside and outside the bay, were examined.

In this phase the Lagrangian module for analysing the paths of discharged substances was applied to the hydrodynamic model and it unquestionably proved the advantages of discharge into the sea outside the bay.

The measures for mitigating the effects on the environment, defined within the terms of the study, included:

•     the definition of the appropriate methods for minimizing risks of accidental spillage;
•    indications of the level of detail of the treatment plants needed to maintain the prescribed standards, even around the discharge zone;
•     the definition of an adequate location for the vegetation belt, to "mask" the new installations, with the criterion of blending them in as much as possible with the local countryside.

A preliminary study of the flora was useful for these proposals.

The more strictly design part was preceded by a forecast analysis of marine and land traffic to define the dimensions of the berths and the storage areas.

The jetty was then designed, developing two different types of construction (piles and cylindrical caissons) and defining the selection criteria based on the results obtained by a more detailed study of into the geotechnical conditions.

The design includes: berths, loading/unloading facilities, electrical and fire prevention plants, telecommunications plant, navigational aids and the measures to prevent and control accidental spillage.

The design for the part on land, on the other hand, includes the storage tanks and the piping networks for fuel oil and diesel oil, the networks and treatment plant for dirty water from washing the tanks and the road and rail access.
