Vortex technique speeds deepwater BOP cleaning

Offshore staff

AMSTERDAM, the Netherlands – Archer introduced a deepwater BOP cleaner at the SPE/IADC drilling conference and exhibition.

The Tornar system is designed for BOP and riser cleaning in deep and ultra-deepwater environments. It incorporates a vortex suction technology to remove wellbore debris from BOP and marine riser cavities safely, quickly and reliably, the company claims.

The tool combines Tornar flow ports with proprietary magnets to extract debris while maintaining full well control and protecting the BOP.

Rolf Egil Håland, Archer’s president and managing director, Oiltools, said: “The accumulation of drilling debris and solids is a serious oilfield challenge which can hinder the correct operation of the BOP and cause extensive loss of time and money…

“The big issue in deep and ultra-deepwater markets is the time it takes to retrieve and re-run the marine riser and BOP, as this can often take several days to a couple of weeks. A major operator in Brazil recently attributed 70% of their downtime to BOP-related issues; with a rig costing more than $1 million per day, such downtime becomes very expensive.”

Archer describes the new system as an advanced version of its shallow-water Tornar BOP cleaner, which following its introduction was deployed on the Gullfaks complex in the North Sea.

The company is presently negotiating a master service agreement with a major rig operator.

“What really sets this tool apart is its combination of riser brush, string magnet, and junk basket to clear the riser of mud and scale, and collect debris. In addition, its three-stage flow sleeve diverts flow out through the cleaning ports or through the bottom of the string, thereby enabling full well control during cleaning operations.”
