WASHING COMPLEXES

FOR SHIP TANKS

BERTHING VERSION

KVO-STp

Technologies currently used for cleaning (washing) of cargo and fuel ship tanks use traditional detergents, including expensive, or just hot water, which entails high level of energy consumption and formation of large volumes of water contaminated by petroleum, which is discharged to special collecting vessels and further to onshore fixed treatment plants, where they are recycled and disposed. This technology is ineffective, requires enormous costs (including heat) for directly washing, disposal of wastewater polluted with oil products and oil sludge. In addition, upkeep and maintenance of onshore fixed treatment facilities in operating condition also require considerable financial resources.

The proposed technology version with use of self-cleaning detergents of «O-BIS» series and mobile equipment «CTG»cut the cost of this process by many times and relieve many environmental problems.

KVO-STp consists of washing module (MP-02) and additional equipment module (MDO-01) and also the capacitor module for collecting sludge and oil residues. These modules and tank are placed inside a 20-feet container, which, in turn, can be installed on containerships, enabling rapid move to objects of washing.

Washing module MP-02 includes all main systems providing engineering process of tank washing, namely, preparation and purification of detergent, delivery of detergent to the surface to be washed, pumping out to the module for separation, etc. Additional equipment module MDO-01 has: steam generator, compressor, diesel power plant, pumps, washing machines with fittings, a set of hoses, sleeves and connecting elements, local heaters etc.

FOR SHIP TANKS

ROADSTEAD VERSION

KVO-STr

Roadstead washing of ship tanks from washing ship is expected to be very promising. In this capacity it is possible to use marine steam tug or petroleum contaminated water collector vessel. Available on this vessel cargo tanks can serve both for carriage of petroleum products, as well as service capacity tanks for:

• pure water detergent «O-BISM»;
• released high-quality petroleum product;
• waste water contaminated by petroleum products;
• solid waste and sludge.

Pumping equipment available on the vessel can be used for delivery and discharge of detergent when performing washing.

Heating of detergent is performed from own boiler, or diesel generator. The vessel shall be equipped with washing machines and hoses.

Thus, the vessel becomes multi-purpose: for collection and transportation of water polluted with oil products, as well as for washing of ship's tanks. With such use with its appropriate environmental safety and efficacy, can perform the following kinds of works on the roadstead:

• washing cargo and fuel tanks of tankers;
• washing of drinking water tanks;
• cleaning and washing of machine-boiler compartments;
• washing of double bottom space;
• reception of waste water contaminated by petroleum products.

When performing woks the washing ship is placed next to the vessel to be washed and connects to the objects of washing by hoses for delivery and pumping solutions. The process of detergent preparation and removal oil from the detergent is performed directly on the washing ship. In addition, there is no need to discharge the detergent - it will be required for washing next vessel, etc.

Availability on the shore of a small stock of tanks for petroleum products and water detergent O-BISM provides with possibility receive and accumulate for sale washed petroleum products and store, if needed, water detergent «O-BISM».

Besides «O-BISM» solution has anticorrosive properties, which positively affect effective life of vessel’s hull.
