3D Mesh Models: Changing the Face of Offshore Asset Maintenance

Moves

Moving of large components around platforms can be a complex and lengthy task. Not knowing its current condition, layout or the spacings or dimensions in between other components can quickly combine to make what, in theory, should be a simple task, very difficult.

Often inaccurate or outdated drawings would further complicate the matter and offer limited insight.

Now with mesh models, we can see surrounding obstacles in real-time and plan large moves well in advance of a site visit. Not limited to the eye-test however, our in-house visualization tool iHawk offers users the ability to measure dimensions and spacing anywhere across the rig, thanks to detailed scaling down of the platform, accurate to the nearest centimeter.

Decommissioning

Almost as arduous as designing and installing an offshore asset, decommissioning takes years of planning that is equally as costly as it is lengthy – and not without risk.

It can be tricky to know how and where to remove parts of an asset without risking the overall integrity of it and therefore keeping the project on track, on time and within budget.

In times gone by, project owners would have to refer to old photographs or, even worse, decades-old drawings, some of which often would omit more recent additions or modifications, such as new pipework, and would have to conduct numerous offshore surveys – all of which further complicate the decommissioning process.

Mesh models have changed all that. Now, project owners can see an up-to-date 3D image of their asset that gives real insight into its current setup and condition and allow them to plan meticulously what needs to be done.

Planning

Previously, even the planning that took place before an assignment was expensive. For example, to plan modifications, it would require numerous visits to the platform to check for potential obstacles or to determine the condition of certain areas to see if they were suitable and ready. The persons performing those duties would require additional bedspace upon the rig, potentially pushing back other work. Then there is the costly factor of helicopter travel back and forth for so many individuals.

The introduction of mesh models allow for the planning portion of the work to be done entirely onshore. There, the project owners can see in near real-time the condition of the asset – whether it may or may not be suitable for modifications to be carried out – or see parts of the platform that would simply be too difficult to access without ropes or scaffolding.
