Connector Subsea Solutions (CSS) is proud to announce the signing of a Memorandum of Understanding (MoU) with Petrobras, Brazil’s state-owned oil and gas operator. This landmark agreement cements our joint commitment to deliver reliable solutions for the region.
CSS’ Ball Valves Preferred Choice for Petrobras

Under this MoU, CSS and Petrobras will collaborate to qualify small-bore ball valves for use in Petrobras’ subsea equipment which are often deployed in challenging environments and ultra-deep waters.
These market-leading valves boast multiple unique features:
- Ultra-compact – optimised for minimal footprint on subsea structures
- Lightweight – Easier handling and operations, and reduces cost across the entire supply chain
- Potential leak paths reduced by 75% – unique market-leading engineering
- Metal and soft-seat sealing – robust and reliable durability in harsh subsea conditions
- High-pressure ratings – up to 15 000 psi suitable for ultra-deep waters
Leveraging CSS’ Experience in Brazil to Advance Subsea Innovations
Through this memorandum, CSS and Petrobras demonstrate a united effort to support the advancement of Brazil’s subsea capabilities. “Building on our tradition of providing reliable solutions for Petrobras, this agreement represents a significant milestone towards our strategic focus of delivering reliable solutions to the region,” said Kristian Karlsen, Senior Sales Executive & Technical Authority.
CSS has been operating in Brazil since the beginning of this century and has gained the experience necessary to extend our presence in the region to meet the ever-increasing demand in the sector.
Kristian concludes, “We look forward to contributing our expertise and working closely with Petrobras to deliver high-performance solutions tailored for complex subsea applications.”
