Insights
An evolving industry requires a new resourcefulness
The oil and gas industry of today continues to change. 2H’s clients need an independent partner who can understand the issues and think creatively. Our unrivalled domain knowledge means we can find new solutions to optimize performance, extend life, reuse infrastructure, reduce costs and improve the environmental footprint.
Inventive, practical solutions for the most complex projects
We have a reputation for pushing the boundaries of known technology and existing methodologies to develop inventive, practical solutions. No matter what your biggest challenge is, we have the tools, knowledge and experience to figure it out.
Holistic systems engineering approach
We don’t look at your system or component in isolation or have a cookie-cutter approach. Instead, our goal is to develop the optimal solution. We consider every aspect of the project lifecycle from design to fabrication, delivery to installation, and operations to maintenance to get it just right.
Making offshore operations cleaner and greener
We are helping clients on their path to net zero by improving the efficiency of existing conventional energy production & operations to reduce carbon emissions. This means incorporating renewable power sources such as using sea water intake risers to improve power generation efficiency and help reduce carbon emissions emission.
