AIS was established in 1963 and is a specialist in the petrochemical industry.

During the 1970s, AIS grew through the acquisition of various major hydrogenation and oil companies, allowing the company to extend its range of services to include offshore rig preparation for the extraction of hydrocarbons.

In the mid-1980s, the company incorporated a new organisational and technical management structure, which consisted of experts and emerging young professionals.

Founded in 1963, AIS is a specialist in offshore engineering services.
AIS performs shutdown services, which include the dismantling of exchangers and plant components.
The company offers maintenance services on offshore facilities.
Pipework and steel structure assembly are also performed by AIS.
AIS worked with Italiana Energia e Servizi to build a new underground liquefied petroleum gas (LPG) plant.
The company has performed engineering services at ENI’s Barbara plant off the Italian coast.
AIS has worked with Italian company ENI to maintain its oil processing facilities.
The company oversaw the mechanical engineering at ENI’s Annabella facility.
AIS was responsible for the installation of KO Drums onboard ENI’s Cervia K rig.

AIS grew with this new structure and developed a number of long-term business partnerships. A number of companies that collaborate with AIS perform specialised tasks, such as electrical and instrumental systems works, insulation, infrastructure building and additional works.

Extraction pipelines for the oil and gas industry

In addition to plant engineering, AIS also lays gas and oil pipelines connecting extraction wells to processing and distribution stations.

Each system is designed and installed with the technical documentation to ensure that the highest quality of the plants is achieved and that they comply with the required industry standards.

Among its installation portfolio, the geothermal plant made on behalf of AGIP SpA in Ferrara, where the AIS is based, is significant as the system allows the use of the underground hot water and sends it to the city’s distribution facilities.

The integrated company system is certified according to UNI EN ISO 9001:2008, BS 18001:2007 and ISO 14001/04.

Technical construction and maintenance services on offshore facilities

Each system designed and installed by AIS includes the technical documentation that contains all the control, operational and security steps, in addition to the procedures undertaken during the different system stages. This procedure is internally applied by a technical organisation that also rigorously checks the production quality.

AIS has technical experience and knowledge of the following applications:

  • Extraordinary maintenance at onshore and offshore stations and refineries in the event of emergency plant improvement and modification
  • Gas and oil pipeline laying
  • Maintenance with programmed shutdown interventions at onshore and offshore facilities
  • Petrochemical, onshore and offshore plant mechanical fitting
  • Skid unit construction
  • Steel structure construction
  • Structure and module construction for the oil industry
  • Turnkey plant realisation
  • Development engineering, maintenance and turnkey plant realisation services

AIS also performs the following services:

  • Complete implementation of the phases elaborated during the engineering phase, final start-up and plant delivery
  • Development engineering, issue of purchase orders, specialised coordination and control may be entrusted to non-destructive testing, heat treatment and electrical instrumental subcontractors
  • Improvements and renovations to onshore and offshore facilities
  • Maintenance services
  • On and offshore plant mechanical fitting
  • Realisation of turnkey plants
  • Research, traceability and supply of construction materials, handling customs clearance and inspection

AIS continually trains its personnel in first aid, fire fighting, survival at sea, driving vehicles, setting up and dismantling scaffolding, intervention procedures, in addition to welding procedure certifications and qualifications.

Project management

AIS has been involved in a number of high-profile projects. It collaborated with Italian energy company ENI to perform post-workover mechanical engineering, exchanger maintenance and the installation of pipe-rack process lines and wellhead pipelines at its plant. AIS has also installed KO drums onboard ENI’s Cervia K rig.

Ais has built for a turnkey contract with ENI, the new cluster and the bridge that connects it to the platform Garibaldi. For Italiana Energia e Servizi (IES), AIS was involved in the construction of a new underground liquefied petroleum gas (LPG) plant, which included pipework, pump fitting and steel structure installation.
