NS-INSTA 800 standards

We perform CDB cleaning according to the NS-INSTA 800 standard during construction of new rigs or ships, and during repair or maintenance projects.

Cleaning according to the NS-INSTA 800 standard is essential to safeguard quality during new construction. We perform and safeguards cleaning on all types of structures and piping / HVAC, tanks and more.
NS-INSTA 800 ensures quality during construction and provides a safe working environment. Under embodiment, different cleaning techniques is performed in relation to the customer activities and purity requirements of the customers.

In an early phase of construction of new structures, it is important to maintain control of waste and dust. At this stage one should also monitor air quality. To document the work underway, it is the visual inspection that are logged in reports with text, video / images. One also takes measurements in air to ensure quality for operators in the working area.

Once the construction is nearing completion, the areas are divided and each area is protected for further contamination. In this phase there is normally stricter protection for shoes, and imposing vacuuming for all tools and equipment. The cleaning is now moving into another phase and other routines apply, with more use of washing with water, soaps and disinfecting chemicals.


The last part of the construction involves a full washdown of all surfaces and pipes and especially the ventilation system. Under construction the ventilation system will be subject to high humidity and a lot of dust, and there will be a need for a important cleanse during the washdown. The most important reason for the cleansing is the risk of the formation of bacteria, that later can cause health problems in subsequent stay in the same environment.
During the full washdown we are required to do sampling to be able to document the degree of purity according to customer specifications. We use special tape and special measuring equipment to check and assure that the quality meets the requirements. The challenge in this period of the project is to keep the areas free of work.

During the whole process it is very important to document the cleaning from beginning to end. All documentation required solved with our unique quality BlueTag. Via BlueTag the customer gets daily project reports updated with pictures, measurements and documents. Everything is accessed through a link stored on-line.
Steam, vacuuming, high pressure flushing, manual washing and special equipment for ventilation cleaning, are equipment that is mostly used in this type of cleaning projects.

Often, during the construction of ships and rigs, rope also access techniques is used, especially the in the last phase of the construction.
