We are happy to announce yet another satisfactory deliverance of grout monitoring. More about this topic below.

How do you get to know the integrity of the grouted connections between piles and sleeves on installed offshore jackets? This has been a recurring question during the past years. Access and methods to inspect the grouted connections is not a trivial ordeal.

Since 2017, FORCE Technology has provided a client with equipment to monitoring of relative movements between the pile and sleeve inside the grouted connection. Just recently, we equipped the subsea monitoring unit with batteries for a new campaign.

Monitoring equipment.

Information on unwanted movement in the grouted connection is highly relevant, and correlated together with data from topside jacket sensors and met-ocean data, the grout monitoring sensors can create a basis for a complete structural integrity plan.

The monitoring unit is installed on the sea floor with a sensor embedded in the sleeve; it records relative movements between the pile and sleeve along two axes with sub millimeter accuracy at a frequency with 2 Hz. The unit is autonomous with optional data download from the surface vessel and ROV, but it can also provide data online if required.
