THE cleaning oil tanker tanks It is an essential activity to ensure operational safety, vessel integrity, and the efficiency of oil and petroleum product transportation operations.
In the sector of oil and gasThere are various types of vessels used in both the production and transportation of hydrocarbons, such as... offshore platforms, FPSOs and oil tankersAll these units that store petroleum or petroleum products need to periodically carry out the cleaning oil tanker tanks, with the aim of removing residue accumulated during the operation.
This procedure is essential to maintain the tanks in proper operating condition and prevent problems related to the accumulation of contaminants inside the storage structures.
THE crude oilWhen stored or transported, it typically contains various types of components and impurities that can accumulate inside the tanks over time.
During loading and unloading operations, the gradual formation of oily sludge, composed of:
These residues end up accumulating at the bottom of the tanks, forming layers of sludge that can reduce the usable storage volume and compromise the efficiency of the ship's operations.
For this reason, the cleaning oil tanker tanks This should be carried out periodically, removing these deposits and restoring the tanks to proper operating conditions.
In addition to improving storage efficiency, cleaning also helps prevent operational problems and preserve the structural integrity of vessels.
THE cleaning oil tanker tanks This is part of the maintenance and preparation activities for vessels in preparation for new transport operations.
This service can be performed in different situations, such as:
The periodic removal of these residues helps preserve the performance of loading and unloading systems, as well as maintaining the safety of maritime operations.
THE cleaning oil tanker tanks It is considered a highly complex activity, mainly because it involves work in confined spaces.
During ship operations, it is common for vapors and gases from petroleum to accumulate inside the tanks. These gases can pose health and safety risks to workers.
Among the most common risks found in oil tanker tanks are:
For this reason, the execution of cleaning oil tanker tanks It requires rigorous planning, continuous monitoring of the atmosphere, and the use of specific safety equipment.
The teams responsible for this type of service need to have specialized training to operate in environments with these characteristics.
The safe and efficient implementation of cleaning oil tanker tanks This requires the use of appropriate equipment for this type of operation.
Among the main equipment used are:
These resources are essential to ensure that activities are carried out safely and efficiently.

On crude oil tankers, part of the cargo tank cleaning is done with the oil itself, during discharge. Crude oil washing (COW) uses fixed washing machines that direct the oil against the tank walls and redissolve the sludge, which leaves with the cargo. Water washing, hot or cold, complements COW when the tank is changing product, receiving clean ballast or undergoing inspection.
Washing water and oily residues go to the slop tanks, where oil and water separate by settling. The sludge left at the bottom of the cargo and slop tanks must be removed and disposed of ashore. This is the residue that oil tanker tank cleaning removes, using suction, manual or mechanized removal, and hydroblasting.
Before any personnel entry, the tank is ventilated and degassed until the atmosphere is safe for work, a condition known as gas free. Release depends on measuring oxygen, flammable gases and toxic gases, and it is renewed throughout the job. When hot work is involved, inerting and measurements follow even stricter criteria.
Annex I of the MARPOL Convention covers the prevention of pollution by oil and regulates the handling of oily residues on board, including washing and discharge records. Removing the sludge for documented disposal ashore helps the shipowner keep these records in order.
For tanks on other types of vessel, see ship tank cleaning. For FPSOs and platforms, see offshore tank cleaning.
It is the deposit that forms at the bottom of the tank during loading and unloading, made up of heavy crude oil sediment, hydrocarbon residue, solid particles, water and emulsions.
Toxic gases, flammable or explosive atmospheres, oxygen deficiency and hydrocarbon vapors. That is why the service requires continuous atmospheric monitoring and trained crews.
When changing the product transported, to remove accumulated sludge, to prepare for internal inspections and for preventive maintenance.
All units that store crude oil or petroleum products, such as offshore platforms, FPSOs and oil tankers.
