Marine And General Engineering
Engineering That Connects Design to Execution
At Offshore Construction Specialists (OCS), our Marine and General Engineering group is the technical powerhouse behind the company’s ability to deliver fully integrated, constructible offshore solutions. From the design of complex marine structures and pipelines to detailed installation analysis for floatovers, trenching, moorings, and subsea installations, our engineers work across all technical disciplines to support projects from concept through execution.
What sets OCS apart is our fusion of deep technical knowledge with on-the-ground constructability. Our engineers interface directly with construction and equipment teams to ensure that every calculation, model and design package is aligned with offshore execution realities. This integrated approach reduces error, saves time, and delivers more efficient results for clients.
While our primary focus is the offshore oil and gas and renewable energy sectors, our team also supports general engineering challenges across a wide range of marine infrastructure projects. All engineering is class-compliant, field-tested, and delivered with clear documentation. Below is a comprehensive breakdown of our capabilities:
