Oil and Gas Installation

Marindotech undertakes field development planning, feasibility, concept and FEED studies for offshore and onshore projects. It is during these phases that our Engineering Services consultancy team can potentially provide world class solutions to positively progress the project forward both technically and commercially. We execute work for both greenfield/new and brownfield/existing developments.

Marindotech has extensive experience in the design of onshore/offshore facilities for both oil & gas treatment facilities and, therefore, is able to produce designs that are fully integrated with any downstream facilities. Our concept development work is supported by a cost estimating function that reflects the very latest cost information through our worldwide procurement capability.

At the concept level our design teams provide robust and practical solutions which incorporate Marindotech’s extensive EPC and operations experience both onshore and offshore. This experience has been gained through executing projects in some of the most environmentally and climatic challenging regions of the world. Using this approach ensures that the correct level of experience is mobilised at the earliest opportunity within a project where its influence can add the most value.

Integrated field development planning

For execution of field development planning, Marindotech consultants and engineers are accustomed to interfacing with client sub-surface personnel to jointly develop the optimum sub-surface/surface solution for the asset. Hence, particularly within our consultancy team, there is an understanding and appreciation of the potential issues associated with aspects such as flowing wellhead pressure on productivity, gathering network pressure drop, artificial lift methods, water injection for reservoir pressure maintenance, gas injection for reservoir pressure maintenance and plateau production periods. Our workflow methods for feasibility and concept studies typically include means of handling data uncertainty by developing and costing options for variation in wellhead/arrival pressures, artificial lift and injection/disposal of gas and water and fluid composition.

Offshore concept development

Identification and assessment of development options for offshore facilities, whether they are based on fixed or floating structures concepts, is crucial in the selection of the most cost effective solution to take forward to the following project phases and to support customers’ investment decisions.

Onshore concept development

Feasibility phase

The objective is to demonstrate both technical and economic viability. Marindotech recognises that every project is unique and we develop specific solutions considering issues such as hydrocarbon properties, impurities (H2S, wax, sand, salt), production gathering system architecture, plant and camp location, processing scheme, refinery configuration, export & storage of products (oil/gas/NGL/LPG/LNG, gasoline, diesel, kerosene), power generation, utility systems integration and enhanced oil recovery methods. Our cost estimates at this stage are developed at screening level.

Concept phase

On completing feasibility assessment, the objective wouldbe to select the best option(s) and further define to reduce risk and improve project cost estimate accuracy. Typical issues include; multi-phase or single phase production flowlines, optimum facilities location, conceptual plant layout, materials selection for plant and pipelines, process plant technology selection (oil, gas, LNG, refining and GTL), process and safety studies, operability, control, overpressure protection, power generation/supply, machinery selection, long lead Item identification, environmental and disposal issues.

The cost estimate will consider market conditions, construction methodology, country specific infrastructure and labour productivity. Our estimating function utilises the very latest cost information through our worldwide procurement capability.

FEED phase

Following successful option identification and assessment during the concept phase, a FEED is an essential part of the project lifecycle. A robust FEED will deliver not just the final concept to be taken forward into construction, but will also provide the estimate for final sanction together with the documentation for the next contracting phases. In addition, in the current climate where schedules are challenging and key equipment often on long delivery times, the FEED output will enable procurement activity to commence prior to main contract award.
