Due to the very nature of incompatibility between the large number and variety of chemical products, a ship may carry for transport, it is highly likely that any semblance of even small amounts of cargo residue between consecutive cargos will produce undesirable effects.
The direct impact of this is on the properties of the chemical cargo, and the risk of contamination leading to rejection of cargo and potential of claims especially for the ship owner / manager.
It is thus imperative that Cargo tank cleaning and fitness to load inspections are given its due importanc
cargo owners require carriage of an intermediate cargo, such as diesel oil, for three voyages after carrying crude oil or dirty products before clean products such as petrol can be transported. The intermediate cargo gradually cleans the tanks, pumps and piping for the subsequent clean oil product.
A crucial task: Tank cleaning
An alternative to intermediate cargoes would be to design a ship to enable switching between dirty and clean cargoes on a ballast voyage. This will however require thorough cleaning to remove traces of previous cargo from internal tank surfaces, cargo piping and cargo pumps and avoid contaminating the next product. Tank cleaning is performed by deck-mounted tank-washing machines.
The tanks are washed with seawater during a ballast trip and possibly rinsed with freshwater to remove the salt residue. There are certain designated areas where the washing water cannot be discharged. When the ship arrives at the next loading port, the tanks will be completely clean.
Our tank washing machines are known for their high-quality performance, efficiency, and durability.

Overview of Cargo Tank Washing Machine
Model YQJ-Q and B tank washing machines are manufactured with advanced technology and high-quality materials. Compared with the traditional similar cleaning machine, it is quite different. The cleaning machine not only has low pressure when cleaning, it also has a long range and the structure of the whole machine is combined. The whole machine is composed of three parts: pressure water cavity, speed change mechanism and automatic clutch nozzle. The three parts can be installed, disassembled, repaired and replaced independently, with simple structure and convenient maintenance. The transmission of the tank washing machine adopts new copper graphite and stainless steel bearing, which has small wear and durability
The traditional tank washing machine is easy to be damaged.When service is needed and turbine, turbine rod and shaft sleeve need to be repaired, all parts must be removed. However, the crude oil tank washing machine only needs to remove a few screws to replace the whole transmission mechanism.
1.Tank washing machine can be operated normally when vessel heeling 15°, rolling 22.5°, trim 5° and pitching 7.5°.
2.Operation temperature is from normal temperature to 80℃.
3.The diameter of pipes for the tank washing machines should be wide enough for all required tank washing machines to work simultaneously under the designed parameters.
4.Tank washing pump can be cargo oil pump or specialized pump the flow of which can make several tank washing machines can work under designed operation pressure and flow.
Tank washing machine type YQJ B/Q is operated with the cleaning medium with flow of about 10 to 40m3/h and with the operation pressure of 0.6-1.2MPa.
The weight of tank washing machine type YQJ is about 7 to 9kg.
Material for tank washing machine type YQJ is copper alloy, stainless steel including 316L.
Following table shows the inlet pressure, nozzle diameter, probable flow and jet length for each tank washing machine.
