Offshore methane monitoring with Nubo Sentry

Why 24/7 methane monitoring is the next step for offshore platforms

Tightly packed layouts limit access to emission sources, while strong winds and saltwater exposure complicate sensor deployment and maintenance. Safety remains paramount, especially as aging infrastructure and tightening regulations increase pressure on operators to detect and manage leaks more effectively. Traditional monitoring methods often fall short in these environments — both in coverage and cost-efficiency. That’s where Nubo Sentry comes in: a compact, high-sensitivity solution designed to simplify methane mitigation, even in the most demanding offshore conditions.

Whether deployed in a dense sensor network across multiple levels or installed at strategic locations only, Nubo Sentry provides operators with a cost-effective, scalable tool that simplifies methane mitigation—reducing risk, improving safety, and supporting sustainability goals. It acts as a valuable complement to existing LEL sensors due to its much lower detection limit, providing early warnings without the need for resource-intensive, frequent LDAR surveys. Minimizing product losses and increasing onsite safety can translate into millions in savings annually.

Extend asset lifetime

Legacy offshore platforms built many years ago were not designed with modern methane monitoring in mind. Retrofitting these assets with traditional leak detection systems is often costly, complex, and disruptive to operations. Nubo Sentry offers a non-intrusive alternative: compact, battery-powered sensor nodes that can be deployed flexibly across hard-to-access areas, without the need for major infrastructure upgrades. By continuously monitoring methane emissions, operators gain early visibility into leaks that would otherwise go unnoticed, enabling timely maintenance and reducing the risk of safety incidents or regulatory violations. This proactive approach not only protects operational integrity but also helps maximize productive life and thus the value of aging infrastructure—making it a strategic advantage.

Future-proof new builds

Designing new offshore platforms offers a unique opportunity to embed smarter, more efficient methane monitoring from the start. With increasing expectations around operational transparency, sustainability, and digital readiness, operators are looking for solutions that are not only compliant but also scalable, low-maintenance, and cost-effective. Nubo Sentry fits seamlessly into this vision: its compact design, hazardous zone certification, and autonomous operation make it ideal for integration into modern offshore layouts. Whether mounted on skids, towers, walls or pipe racks, it delivers continuous, high-sensitivity methane data without the need for complex infrastructure. By choosing Nubo Sentry during the design phase, operators ensure their assets are equipped to handle future demands—from performance optimization to environmental stewardship—with minimal effort and maximum impact.

OGMP Level 5 simplified

To reach OGMP 2.0 Gold Level, operators must reconcile detailed source-level (L4) and site-level (L5) methane surveys. In practice, this often means running simultaneous L4 campaigns and multiple L5 aerial surveys, with operational teams on standby to resolve discrepancies in real time—driving complexity and cost. Nubo Sentry closes this gap with continuous, close-proximity monitoring that reduces uncertainty, speeds root cause analysis, and streamlines compliance. With real-time insights and a clearer picture of offshore methane emissions, operators can meet stringent reporting standards with confidence and efficiency.
