This course aims to master the elements of language and to understand the mechanical systems, in terms of design, characterization and maintenance/repair and to remind or learn how to work on a pump, and more generally on a machine, in a workshop.
Public :
Technicians from the Oil & Gas industry in connection with equipment and mechanical systems (operation, maintenance) who wish to acquire best practices or to upgrade their knowledge about these systems.
Positions mainly concerned are: mechanics, mechanical work preparators, mechanical supervisors.
Level :Knowledge
Prerequisite :
Provide evidence of a professional experience of at least 1 month related to the concerned field.

Duration : 0.5 Day
Machine alignment techniques: comparators and lasers.
Calculations on practical cases.
WEEK 2: HANDS-ON ACTIVITIES IN WORKSHOP
HANDS-ON ACTIVITIES IN OUR WORKSHOPS WITH OUR TOOLS & METROLOGY INSTRUMENTS
-
Duration : 5 Days
Work on motor/pump block (asynchronous motor/overhung centrifugal pump) and work on double shaft centrifugal pump.
Receipt of a pump from the plant or the site(*).
Use of the technical file, maintenance routings and understanding of anything related to the schemes and information files: dimensions, adjustments, tolerances, functional clearance.
Identification of the spare parts(*).
Presentation of the tools in a metrology workshop, performances and rules of use.
Compliance with disassembling/assembling procedures.
Geometrical inspection of the piece of equipment.
Inspection of the condition of the elements and the wearing parts at disassembly: corrosion, defects, coupling, wear, rupture.
Inspection of clearances at disassembly.
Functioning and use of support equipment: bearing heating by induction, monochromatic light for mechanical seal inspection(*)…
Tests after repair and compliance with good practices.
Preparation of an intervention report.
For in-house courses, the above-described hands-on activities can be carried out in-house workshops and on-site, on a piece of equipment to be repaired or overhauled, with in-house tools and metrological instruments.
(*): indicates activities that can only be performed in the case of an in-house course in in-house workshop.
Learning Objectives
Attendees will be able to implement the following skills:
Know the basics of technical drawing, characterize a part, a mechanical assembly,
Master the rules of the art of mechanical system design, identify the main assemblies such as bearing assemblies,
Know the main elements of power transmission (gears, gimbals…),
Wisely use the metrology instruments used in the workshop (use, performances, calibration),
Carry out a disassembly and assembly routing of a centrifugal pump – and more generally of a machine – by completing the dimensional and geometrical inspection required.
Ways & Means
Very interactive course by highly experienced trainers.
Practical work in the workshop.
Stepwise approach, from the dimensioning of a simple part to the assembly in the workshop.
Learning assessment
Written test and practical assessment in the workshop.
