Offshore inspection, cleaning and repair solutions transformed with innovative new approach

In a collaboration between TRAC Oil & Gas and ToolTec, this project developed a cleaning and inspection tool (Trac-Tec Tool) that can be remotely deployed from the platform, to clean and inspect various sizes and configurations of caissons and conductors in the area immediately above and below sea level, or 'splash zone'.

Typically, inspections are carried out by divers from a diving support vessels (DSVs) or remotely operated vehicles (ROVs) deployed from the platform or a vessel. This can be challenging due to the sea state and proximity to the jacket structure, not to mention the use of support vessels being expensive. This new technology delivers a solution that removes the need for divers, ROVs and DSVs. Phase one that focussed on the development of the tool, with the second phase proving the concept via field trial.

Industry Value

The technology has the potential to reduce inspection costs by 50%, while improving safety, quality and efficiency.

Typical annual workscopes for an individual platforms splash zone inspection range from £300,000 to £3 million, based on various riser, structural and pipeline schedules, and using ROVs/divers. By using the TracTec Tool, the cost to carry out similar workscopes are in the region of £15,000 - £150,000, providing a 95% cost saving.

Key Results

The tool was trialled on four caissons in the North Sea to test and prove functionality.

The project has also been shortlisted in the Innovation category of the 2019 Press & Journal Energy Voice Gold Awards.

Speaking of the shortlisting, Business Delivery Manager Jan Stander said: "Working with ToolTec on this specific project, supported by OGTC, has enabled us to pool our respective expertise and has led to a solution which has enormous safety and cost benefits for the oil and gas industry as a whole."

Lessons Learned

In addition to cost savings, the system also allows for higher quality inspection data to be obtained, improving the integrity of caissons and conductors. This enables more frequent inspection campaigns and the proactive development of appropriate and cost-effective remediation plans if required.
