Monitoring of underwater pipeline assets

VRT’s cooperation with Alva (formerly Jyväskylä Energy Group) helps the Finnish energy company in construction, maintenance and post-construction asset management.  Multibeam sonar inspections and detailed 3D data delivered through GISGRO online-service provide Alva a solution for baseline information before the construction, quality control and assurance during the construction and monitoring of the structures. With long-term cooperation, change comparisons are possible, which facilitates predictive maintenance and asset integrity management.

VRT Finland and Alva have been collaborating for years. VRT has performed underwater sonar inspections and surveys for Alva in different locations. Alva planned and constructed a 25-kilometre long wastewater transfer pipeline between Lievestuore and Jyväskylä as a part of Alva’s Pisara concept.

About 7 kilometres of the transfer pipeline were installed in the bottom of the lakes in Leppävesi, Päijänne and Jyväsjärvi. The multibeam sonar inspections were performed in order to collect and check the baseline data for planning the new pipeline. After constructing, the installed pipelines were surveyed with the same technique.

The digital measurement results collected with sonar inspections were delivered for the client via a web-based portal, GISGRO. In the Lievestuore project Pisara is piloting how this portal can be utilized among all the parties involved in the project, and in the asset management of pipeline’s lifecycle. With the pilot carried out in our cooperation, one new model is inspected in the field of digital modelling.

– VRT was the first in the world to perform structural inspections with required accuracy using sonar technology, and we are also the first ones in the world to offer the possibility for the client to utilize and analyze the collected 3D data easily via GISGRO online platform, states VRT’s VP Business Development Mikko Kolehmainen.

In the collaboration, the know-how of both companies is combined and the information collected from the sonar inspections is utilized wisely in the needs of planning, constructing and maintaining the pipelines.

"The amount of digitalization is growing up in all construction projects and during these days a lot of information is saved in even more accurate form. Digital material can be already utilized variously in planning the construction work. Virtual technology increases the utilizing possibilities in the future even more"
