Dover Engineering Limited’s capabilities in the offshore market are focused on the design and engineering of platform topsides and floating production, storage and offloading (FPSO) systems.


A leading designer of topsides and processing equipment for offshore oil and gas production, Dover Engineering Limited backed up by seasoned technical partners, WoodGroup, has designed platform topsides. Our topsides have provided years of safe and reliable operation in a variety of climate, water and reservoir conditions.

 Floating Production, Storage and Offloading (FPSO)

Dover Engineering Limited has been instrumental in the design of FPSO units to the offshore oil and gas industry in Nigeria. Over the past years, we’ve provided design and engineering services for quite a number of FPSO projects.


Dover Engineering Limited has designed and managed some of the nation’s largest onshore pipeline projects. With more than a decade of pipeline experience to our credit, we’ve earned respect for our ability to deliver successful pipeline projects even in the most challenging locations.

We’ve designed pipelines for transporting crude oil, natural gas, refined petroleum products, LPG, LNG, NGL, condensates, water, slurries and various chemicals—both in single-phase and multiphase flow. These pipelines have ranged in

In the last 10 years, Dover Engineering Limited has been involved in planning, permitting, concept and FEED efforts of pipelines across terrains in Nigeria. In addition, we have executed contracts for several projects, leading to the safe and timely installation of several pipelines, where our scope included engineering, procurement, construction management and support services.

In addition to planning and designing pipelines, we provide complete design-build services for associated facilities, such as compression and pumping stations, pig traps, slug catchers, valve stations, terminals and reception facilities.

Dover Engineering Limited’s areas of technical expertise include:

  • Geohazard and seismic design
  • Crossing design, including horizontal directional drilling (HDD) and microtunneling
  • Risk assessment and safety analysis
  • RAM and modularization studies
  • Flow assurance analysis both under steady state and transient conditions (including multiphase, multi-product, non-Newtonian and high temperature/high-pressure fluids)
  • Limit state design
  • Materials and welding
  • SCADA and telecommunications

Dover Engineering Limited’s extensive in-house library of benchmark cost data for various pipeline and process facilities support our value engineering process and ensure the most cost-effective pipeline design.

The planning and execution of a pipeline project requires extensive knowledge of numerous geographical, political, regulatory, social and environmental issues. With our expertise combined with our seasoned partners, we have people in every major market who can provide the specialized knowledge and skills needed to work effectively with landowners, local authorities and environmental agencies.
