3D Laser Survey on one of the worlds most advanced diving support vessels.

Sep 13,2019

In addition to our unique manufacturing capabilities Fiber Glass Systems also offer a wealth of expertise and experience in Engineering Services, including 3D Laser Surveys.

We have the ability to deploy a member of our Engineering Services Department (ESD), often at very short notice, to survey your project whether it is situated offshore in the middle of the North Sea, underground in a London train station or even aboard a Diving Support Vessel (DSV).

DSV’s provide vital subsea construction, inspection, repair & maintenance and decommissioning services to offshore oilfields and facilities.  When existing galvanised metallic pipework on their sea water cooling system corrodes beyond repair, it can lead to problems with fouling and blockages and have a detrimental effect to the heating and cooling of the seawater supply to diver’s suits.

In a recent project we were asked to conduct a 3D laser scan and provide an advanced solution in order to repair this advanced piece of equipment.

Our Engineer spent a total of 48 hours over the course of 4 days completing 98 separate laser scans using Faro Focus 3D Scanner & Leica Total Station.  The scans were conducted across 6 decks on-board the 145m long vessel, providing a clear route of the corroded pipeline.

The survey allowed our ESD to overlay the data gathered on-site with the 3D model supplied by the client to ensure both models coincided with each other.  Any clashes this operation identified would require the replacement pipework to be re-worked and re-routed to avoid on-site clashes.  The design required Lloyds Register Quality Assurance (LRQA) approval prior to installation.

We subsequently supplied and installed approx. 200m of Bondstrand® GRE pipe ranging from 2 to 3 inches in diameter, together with pipe supports, penetration seals and lagging.

We were also able to fabricate 80% of the pipework off-site at our innovative manufacturing facility to enable a fast track installation in line with project requirements.  Four Fiber Glass Systems Installation Engineers were then deployed on site for approx. 4 days, working 12 hour shifts to complete the installation and enable the vessel to resume its critical support services.
