Civil works include preliminary groundwork of the project site area (excavation, construction of access routes, trenching and backfilling, clearing of drainage, construction of security fences, asphalting and concrete works) and the construction of buildings and structures to house the operations of the project, such as accommodation facilities, material and equipment storage areas, as well as offices which are needed throughout the project execution period.
Structural
Structural works encompass the fabrication, installation and erection of steel or stainless steel structures used in the construction of oil rigs, refineries, petrochemical plants and other facilities. Through its steel fabrication factories, the MMG fabricates steel structures, stages and platforms and various types of mechanical equipment such as pressure vessels, fired heaters, heat exchangers, boilers, storage tanks, towers, drums and pressure piping.
The raw materials used in the fabrication of steel structures and mechanical equipment are carbon and stainless steel sections such as plates, pipes and rolled sections which are supplied by the main contractor of the project and fabricated according to the outlined drawings.
Mechanical
Mechanical works include piping fabrication, scaffolding, rigging and mechanical equipment installation.
Pipes are fabricated by MMG in accordance with the main contractor’s drawings and supplied unprocessed pipes. The fabrication steps include cutting, welding, fitting, sandblasting, painting and cleaning. The fabricated pipes are then installed by MMG on our premises. Scaffolding is necessary for works and inspections that cannot be performed from the ground or a secured platform. Rigging is required whenever heavy lifting is involved.
Upon completion of the mechanical equipment installation, external accessories, parts and components are installed or assembled as per the client’s drawings, after which an initial test on the equipment is undertaken.
Electrical and Instrumentation
Electrical works include the installation of electrical systems throughout the facility which include: conduit and cable tray installation, cathodic protection, cabling, grounding systems, duct bank installation, electric motors and generators, switchgear installation, relays and breakers, transformer and junction box installation, motor control centre and control panels, as well as lighting and communication systems.
Once the electrical systems are in place, the installation of instruments such as, transmitters and transducers, control valves and switches, safety relief valves, analysers and indicators can take place. All instruments undergo a series of testing and calibration as required by the main contractor before installation.
After completing the installation of instruments, a loop check is performed. This quality review consists of testing and identifying faults or failures in the entire system, which interconnects different instruments and processes.
