What we do


With decades of experience, Frontica Engineering is your specialized engineering partner for developing and documenting design solutions according to your needs. Our multidisciplinary staff is a team of highly educated specialist engineers.

Our main activities are related to offshore production & drilling facilities and renewables. Examples of projects within renewables are offshore wind and zero emission technologies (hydrogen and ammonia).


We have experience from all project phases:

Our core business is concept development, feasibility study, Front End Engineering Design (FEED) and detail engineering as well as Engineering, Procurement and Construction (EPC) projects. The projects that we have been a part of in the North Sea have all been great technical achievements for their time and have set new standards in the offshore industry. This includes permanent installations for both fixed and floating process and utility units.

Our engineering references related to offshore drilling facilities design go back to the early 1980s (Norwegian Rig Consultants). Since then we have developed  concepts, systems, layout and structural arrangements to permanent and mobile offshore units in parts of the world where oil and gas exploration take place in harsh weather conditions.

We have worked with most of the major oil and gas companies and taken part in their field development programs. In addition, we have worked with most design houses and fabrication yards for mobile offshore drilling units (MODU’s).

Frontica Engineering has experience from all project phases from concept development, feasibility, front end engineering design (FEED), detail engineering, construction support at yard and onshore and offshore completion for both greenfield and brown field applications.

Typical areas where we take full responsibility for design:

  • Design of optimal drilling concepts, functionality and operation
  • System and area design:
    • Drill floor including derrick, substructure and moon-pool
    • Pipe, riser and storage decks
    • Mud, cement, bulk and treatment areas
    • All drilling utility areas
  • Drilling control and monitoring systems

  • White Rose Extension
  • Snorre A Drilling Facilities
  • Oseberg B Drilling Modifications
  • Grane
  • Valhall
  • Oseberg Øst
  • Snorre A/B

Frontica Engineering has been involved in offshore wind development projects for some years and are partners to others by assigning specialist engineers.

We are involved in concept development of new in-house designs and solutions for floating wind in addition to involved in other zero-emissions technologies such as hydrogen and ammonia related projects.

Some reference projects we have been/are currently involved in with personnel:

  • Dogger Bank A, HVDC platform
  • DolWin Epsilon, HVDC platform
  • Hywind Tampen
  • Flagship, HVDC platform
  • Northern Lights, CCS
  • DolWin Beta, HVDC platform
