Where People Meet The Offshore Engineering Industry

Our Mark People are the most important part of any engineering project. Every drawing, report, design, or technical opinion ever created during a project’s execution is useless if it isn’t used to get to the project’s mark. The perfect project runs on time, is mistake-free, and is under budget; but that’s only possible when all the stakeholders agree to this goal, and are empowered to make it happen. Windward Mark Engineering is committed to getting the most out of any project engineering team by helping everyone involved focus on the mark ahead.
