Abstract. In addition to the generally accepted constructive solutions in Antarctica to prevent fuel leakages from
the fuel tank the development and the mounting are proposed of the automated control system of the tank
functional state for the early warning of possible fuel leakages.
Such automatic system for control of the fuel tank functional state under the Antarctic conditions is proposed for
the first time.
Key words: Antarctica Environment Protection, control automatic system, fuel leakages prevention.
Protocol on Environmental Protection to the Antarctic Treaty demands the execution of high
international standards of the Antarctic environment protection. Especially Antarctic nature expects
protection in the regions of the research stations location where there is profound effect on
environment from investigator's life support facilities.
In particular one of the most dangerous sources of possible contamination of the environment
in Antarctica are the fuel tanks both at the national stations and at ships that operate in Antarctica.
Recognizing the importance of this issue, Scientific Committee on Antarctic Research (SCAR)
recently establish the special Action Group on Antarctic Fuel Spills (AGAFS).
At Vernadsky Station the new fuel tank is installed which has replaced the old fuel tank of
3 Station Faraday. New tank has the two cylinder design with capacity 200 m and is welded in situ from
stamped and bended components.
The tank functional condition is characterized by:
·tensely-deformed state of internal and external capacities shells of fuel tank;
·presence of the tensions (stress) concentrators at the internal and external tank shells that are
caused by technology of the tank electro-welding from separate elements;
·modal (natural modes and shapes) and dynamic (vibration) characteristics which are caused
of constructional and technological conditions of the tank assembling. These characteristics
also depend on external dynamic excitations such as wind, snow and ice loadings; seismic
waves; daily and season temperature variations; season variations of fuel level in tank;
·micro- and macroflaws topography in the tank construction which ñàn lead to fuel leakage.
In addition to the generally accepted constructive approaches in Antarctica to prevent fuel
leakage from the tank the development and mounting are proposed of the automated control system of
the tank functional state for the early warning of possible fuel leakage.
This system of the on-line tank inspection will provide:
·determination of the current values of modal characteristics, static deviation of the tank
construction vertical and dynamical characters of tank construction elements under the
exposure of the Antarctic external dynamic excitations; estimation of the stress
characteristics and stability of the tank construction;

·control of foundament vibration characteristics which are indications of the dynamic loading
change on a tank construction;
·finding and localization of the micro- and macroflaws and of tank construction damages
which ñàn lead to fuel leakage;
·gas analyzer control of an air composition in the space between the tank capacities walls for
the detection of fuel leakage from the internal capacity;
·automatic acquisition and transformation of diagnostic information, visualization,
processing and storage of diagnostic information for decision making about the tank
functional condition.
For this purpose following develoments and scientific-technical elaborations will be
undertaken for creation:
1. Vibro-diagnostics subsystem to define dynamic characteristics (vibration spectral
characteristic) of the tank structural components and tank foundation, to inspect of theirs development
and micro- and macroflaws appearance in the tank structure.
2. Subsystem of mathematical simulation for the analysis of the stability characteristics and
tension of tank construction taking into account an influence of the real external dynamic
disturbances according the measuring results in the vibro-diagnostics subsystem.
3. Acoustic emission subsystem to control of appearance and development dynamics of the
tank damages.
4. Subsystem of gas composition analysis and control of air samples from the space between
the tank capacities walls for the detection of fuel leakage from the internal capacity.
5. Automatic subsystem of acquisition, storage, processing, and visualization of diagnostic
information about the tank functional condition at Vernadsky Station.
Proposed system will include such new features:
1. Integrated approach to the problem of the tank functional state control in Antarctic
conditions which provide:
·acquisition, analysis, and application of the information about the real tank structure
vibration conditions;
·development of the tank and its action mathematical model in real conditions of dynamic and
static loading to define characteristics of tank durability and construction intensity;
·information acquisition about tank damages development using acoustic emission
inspection;
·acquisition and analysis of the information about the tank foundation vibration state to define
signs of dynamic and static loading changes;
·information gathering and analysis of the air samples gas composition from the space
between internal and external tank capacities for the detection of fuel leakage from the
internal capacity;
·automatic acquisition and diagnostic information transformation, visualization, processing,
and storage for decision making about tank structure and prediction of its condition.
Data base produced by monitoring system during the first year of operation (when as inspected
the fuel leakage is absent) allows to create a virtual image of the tank functional state at Antarctic
conditions. During further system operation it will be possible to compare the initial virtual image
with the image of current tank functional state. Difference between the initial and current tank
functional state will tell about the possibility of the fuel leakage.
2. Use of the natural sources of the dynamic and static loading instead of artificial ones.
3. Such approach and developed system will lend to tank the new quality of “sensible”
(“smart”) what foresee on-line automatic acquisition and processing information about tank
functional condition.
4. For the first time the static and dynamic loadings on the tank construction in Antarctic
conditions are taken into account which can cause changes of tank functional state.
5. The tank dynamic model will be developed for the first time. This model gives possibility to

determine current characteristics of the tank and the tank foundation, to display tank characteristics
and theirs changes, and predict tank state on the field climatic and dynamic loadings.
The dynamic model development foresees:
· acquisition and processing of the on-line information from transducers placed on the tank;
·visualization on the computer monitor of the tensely-deformed state of tank shells with a
denotation of areas of the tensions concentration and possible areas of the cracks rice in the
tank shells;
·simulation of the tensely-deformed state and the tank dynamic behavior under the periodic
winds and seismic loadings;
·determination of the tensely-deformed state of tank shells from the daily and seasonal
temperature differences and seasonal difference of fuel level in the tank;
·simulation of possible engineering decisions for operative modification of the tank
construction with the purpose of estimation of decisions efficiency.
The team of development investigators and engineers is intended to obtain such Results:
1. Scientific Results:
1.1. Amplitude-frequency characteristics will be investigated of acoustic emission transducers
which made from different materials and transducers directional diagrams; correlation will be studied
between different manners of tank breakdown and monitored parameters under the Antarctic

Scientific Committee on Antarctic Research and will be recommended for application at Antarctic
Stations of other Antarctic Treaty Parties as the necessary component (as International Standard) of
the fuel-oil safe storage and handling systems in Antarctic Region.
3.2. The developed automatic control system of the functional state of a fuel tank will be

at Antarctic Stations of Antarctic Treaty Parties in a complex with designing, making in Ukraine of
fuel tanks and delivery theirs in Antarctic Region and with assembling and installation of the
automatic control systems by means of Ukrainian experts and organizations.
For out-of-budget funding of the indicated system the Full Form (Request for Proposal) was
developed in accordance with the procedures of international Science and Technology Center in
Ukraine (STCU). Nowadays the international audit of the Full Form has been carrying out. Relevant
Letters of Support were already received from British Antarctic Service (BAS), Committee on
Antarctic Research and the Canadian Polar Commission, Alfred-Wegener Institute for Polar and
Marine Research.
