Cutting-edge oil and gas solutions:

Upstream Advisory

Ayesa provides comprehensive services for exploration and production companies, drilling operators, and field development projects. Our services include:

Engineering Development: We manage major investment projects for existing and new production plants, covering basic, conceptual, and detailed engineering, FEED (Front End Engineering Design), detail engineering, HAZOPs (Hazard and Operability Studies), construction supervision, and plant enhancement.

Production Plant Upgrades: We install new reactors, exchangers, and stripper disks and modify plants to handle a diverse range of crude oils, including naphthenic, sweet, sour, light, and heavy crudes. Our services include updating valves, pumps, pig traps, interconnection lines, and electrical substations to ensure optimal performance.

Facility Installation: We oversee the installation of new crude oil tanks and modernize coagulation areas. This involves detailed design and engineering across multiple disciplines, including power systems, civil engineering, instrumentation, automation, piping, mechanical systems, and steel structures.

Construction Supervision: We provide procurement and construction supervision for offshore and onshore facilities, encompassing process engineering, mechanical equipment, piping, civil works, and electrical and instrumentation systems.

 

Midstream Advisory

In the midstream sector, Ayesa delivers comprehensive solutions for transportation and storage, including:

Pipeline Projects: We design and supervise pipelines including oil pipelines and gas ducts. Projects such as the North Peru Pipeline span over 1,000 kilometres and traverse complex terrain.

Crude Oil Unloading: We support the transfer of crude oil unloading operations to new facilities, including designing control rooms and installing booster pumps.

Storage and Distribution: We design and construct storage and distribution terminals and tanks, incorporating essential fire suppression systems to ensure safety and compliance with industry standards. These systems detect, control, and extinguish fires, protecting valuable assets and minimizing risk.

 

Downstream Advisory

Ayesa assists clients in refining, distribution, and energy efficiencies through:

LNG Filling Stations: We offer comprehensive engineering services for LNG filling stations, supporting applications such as marine bunkering, vehicle refuelling, industrial processes, power generation, and commercial use. Our services include process design, mechanical specifications, civil works, electrical design, and instrumentation.

Thermal Energy Recovery: At LNG regasification plants like the one in Barcelona, Spain, we capture and reuse cold energy from the regasification process. This includes installing central cooling units and managing piping and control systems.

Retrofitting Distribution Plants: We specialise in retrofitting distribution plants to replace traditional fuel systems with renewable forms of energy including renewable gases. This process includes upgrading infrastructure, modifying existing systems, and ensuring a seamless transition to more sustainable energy sources.

 

Key Assets include:

Piping and Terminal Facilities: Designing and upgrading piping systems and new terminal facilities.

Pump Stations: Engineering and design for new pump stations, including capital maintenance like pump replacements and equipment upgrades.

Gas and Liquids Facilities: Designing gas compressor stations, metering facilities, district regulation stations, and systems for regulation, odorization, heating, and metering.

Power and Control Systems: Designing power substations and control systems.
