Why choose us for mobile offshore production unit (MOPU) engineering? 

Aquaterra Energy is a world-leading provider of engineering for mobile offshore production units (MOPUs), supporting the design, development and integration of MOPU-based solutions across the full project lifecycle.  While we do not supply or operate MOPUs themselves, we deliver the specialist engineering that enables them, from topsides processing equipment, utilities and deck layouts through to wellbay structures, conductor systems, risers and tensioning equipment. 

Our proven experience in designing platform topsides is directly transferable to MOPU developments, helping operators integrate production-critical processing systems with the wider structural and well access requirements of the unit. We are also spearheading the development of the wellbay module concept, providing a flexible approach to offshore field development.

The benefits of MOPU-based developments include:

Global expertise

We have designed, manufactured and installed wellbay modules and tensioning equipment on MOPUs and mobile offshore drilling units (MODUs) across key regions including the North Sea, Egypt, Asia and West Africa. This experience is supported by our wider platform topsides engineering capability, giving us a strong understanding of the processing equipment, utilities, deck layouts and system integration required to make MOPU developments work in practice. 

Our team delivers complete, end-to-end engineering support, from concept and FEED through to structural and mechanical engineering, topsides equipment design, conductor and riser analysis, fabrication support, project management and offshore installation. 

Beyond individual components, we support the engineering and delivery of MOPU-based developments across a range of subsea and surface well configurations, reflecting the various ways MOPUs can be deployed, from standalone processing hubs to integrated wellbay and platform-linked solutions. 

This enables us to tailor each solution to suit specific project requirements, supporting flexible development strategies from concept through to operations.

We offer a full-lifecycle package, including: 

  • FEED and concept select studies 
  • Structural and mechanical engineering 
  • Conversion equipment & services 
  • Topsides equipment design 
  • Pre-drilling & suspension 
  • Conductor and riser analysis, design, fabrication, project management and offshore installation

MOPU as a flexible field development solution

MOPUs are widely recognised as an efficient approach to offshore field development, but their value extends beyond simple economics. As part of a broader development strategy, they provide a flexible solution that can be adapted to suit a range of field conditions, production profiles and long-term asset plans, leveraging between CAPEX and OPEX spend. 

Aquaterra Energy’s experience in integrating platform topsides, production systems and well access infrastructure enables operators to configure MOPU developments around specific field, reservoir and production requirements. This supports a more flexible, phased approach to development, helping operators respond to uncertainty while optimising investment over time. 

Operational excellence, MOPU systems

Our extensive track record in platform topsides engineering is directly applicable to MOPU developments, where a core engineering focus sits within processing equipment, utilities, deck layouts and the integration of production-critical systems.  

Alongside this topsides capability, our detailed understanding of jack-up rig capabilities, drilling operations, wellbay modules, conductor systems, risers and tensioning equipment enables us to support the full MOPU configuration. This means we can help operators bring together the processing, structural and well access elements needed to suit different field requirements.  

Whether enabling surface tree developments, supporting subsea tiebacks, or integrating with adjacent structures, this approach gives operators a flexible route to production across different water depths, well counts and operating conditions. 

Other benefits include: 

  • Custom engineering 
  • End-to-end service 
  • Cost-effective solutions 
  • Innovative approaches

A flexible approach to offshore field development

MOPUs provide a highly flexible approach to offshore field development, enabling operators to adapt project strategies in line with subsurface uncertainty, production performance and long-term asset plans. Rather than being limited to specific field types, they support a wide range of development scenarios, from early-stage deployment through to full field life and future optimisation.  

This flexibility allows operators to take a phased approach to development—starting with a smaller number of wells and scaling over time as production is proven or expanded. By enabling earlier first production and reducing upfront commitment, MOPUs can support more informed decision-making and staged investment across the life of a field.   

As field requirements evolve, MOPUs can continue to support production, be integrated with additional infrastructure, or be redeployed entirely—offering a level of lifecycle adaptability that fixed platforms cannot provide. This not only improves project economics, but also enables efficient field abandonment and long-term asset reuse.
