With Contract Valid Until October, The Drillship ODN II, Operated By Foresea, Reinforces Petrobras Operations With 98.6% Efficiency And Cutting-Edge Technology For Ultra-Deep Waters.

The drillship ODN II, operated by the company Foresea, continues to operate in partnership with Petrobras in the deep and ultra-deep waters of the Brazilian coast. The drilling unit, considered one of the most advanced in its category, remains under contract with the state-owned company until October 2025.

Designed to operate in water depths of up to 3,000 meters and reach drilling depths of 12,195 meters, the ODN II is a strategic asset for oil exploration in challenging environments.

Built in 2012, the drillship represents a technological evolution in the offshore industry and stands out for its operational performance. In the last three years, it has maintained an uptime rate of 98.6%, meaning almost no interruptions in activities, which reinforces its reliability and efficiency.

Drillship ODN II: Cutting-Edge Technology At The Service Of Offshore Drilling

The ODN II is a 6th generation drillship, equipped with a DP3 Kongsberg dynamic positioning system, which ensures maximum stability even in severe sea conditions.

This feature allows the vessel to remain fixed over the well without anchoring, which is essential in deep waters.

Additionally, the vessel has a NOV drilling package with a capacity of 2,000,000 lbs and is ready to operate with the Managed Pressure Drilling (MPD) system, a technology that enhances safety and precision when dealing with complex geological formations.

An important differentiator is the Junk Catcher, a device that prevents debris from disrupting operations.

Robust Structure Prepared For Extreme Challenges

At 238 meters in length and a drilling tower of 64 meters in height, the ODN II was designed to sustain intense and continuous operations.

The vessel is also equipped with vortex suppressors (fairings) and an acoustic profiler (current meter), essential tools for operating in areas with strong underwater currents and minimizing the effort on the equipment installed on the seabed.

The unit’s BOP (Blowout Preventer) system, with high-pressure rams and annulars, provides additional safety against potential incidents during drilling.

History Of Excellence And Strategic Role In National Production

Originally owned by Odebrecht Óleo e Gás, the drillship is now part of the fleet of Foresea, a company that took over operations after restructuring.

Since then, the drillship ODN II has consolidated its reputation as a key player in Petrobras projects, especially in the most complex sedimentary basins off the Brazilian continental shelf.

According to experts, the combination of state-of-the-art technology, operational efficiency, and high drilling capacity makes the ODN II an ideal platform to support the expansion of national oil production with safety and productivity.

With a track record marked by high performance, the drillship ODN II represents the cutting edge of deep-water drilling.

Its operation alongside Petrobras reaffirms the importance of having reliable equipment and advanced technologies to face the challenges of the pre-salt and other strategic areas of the Brazilian coast.

The partnership between Foresea and Petrobras shows how the Brazilian offshore sector continues to evolve, supported by cutting-edge infrastructure and commitment to operational excellence.
