Platform Deformation Survey

Offshore platforms are exposed to deformation due to the instability of the platform and other factors caused by plate motion or post-seismic motions of an earthquake. The use of Space Geodetic Techniques, particularly Global Navigation Satellites System (GNSS,) to monitor the deformation of a structure has been increasing in demand over the years.

Platform Deformation Survey is necessary to detect and estimate the motion rate and the displacement magnitude between two GNSS observation epochs. Combined with terrestrial levelling technique, a complete deformation analysis can be performed in terms of point displacement, platform tilting as well as the orientation.


Continuous Subsidence Monitoring Survey (CSMS)

Continuous Subsidence Monitoring Survey (CSMS) is the operations of determining the subsidence over a longer time frame. This technique uses GNSS data, processes the data by utilising specialised processing software and then analyses the geometrical stability and vertical motion on the offshore platforms.


Structural Dynamic Monitoring and Integrity Assessment

Exclusive agent of

Siri Marine B.V. specializes in Condition & Motion Monitoring and owns in-house manufactured integrated Motion Sensors which is a state-of-the-art monitoring system. HGIS is now proudly the Malaysian Local Agent for Siri Marine B.V.

While deformation survey assesses the subsidence and displacement of the structure/platform, offshore structures and even onshore structures are exposed also to natural forces such as weight/load, wind forces, waves, jack-up-up leg subsidence and even earthquakes in specific seismic areas. All these causes the natural frequency of motions/impacts to the structure which in the long run may lead to changes in the condition and structural integrity of an object.

Therefore, by having to perform a Structural Dynamic Monitoring and Integrity Assessment, the health and fatigue of structures/platform can be monitored 24/7 to assess the integrity with its behavior on the natural frequency vs the designed frequency. It can also be used as a decision support tool during rig moves and jacking operations to prevent immediate damage.
