General Arrangement Drawings
Review of overall rig layouts, dimensions, equipment positions, working areas, access arrangements and interfaces.
Al-Etimad provides detailed technical review and confirmation of engineering, fabrication and installation drawings for drilling rigs, workover rigs and associated oil & gas equipment.
Our objective is to identify inconsistencies, interface conflicts, missing information and technical discrepancies before they create costly problems during manufacturing, installation, testing or commissioning.
A drilling rig package involves hundreds of technical drawings produced by multiple engineering disciplines, OEM manufacturers, vendors and subcontractors.
If drawings are not properly coordinated, discrepancies can remain hidden until fabrication or installation begins. Our structured technical review helps verify accuracy, consistency, coordination and practical suitability before execution.

Our drawing review can cover the key engineering documents required throughout fabrication, installation, testing and final acceptance.
Review of overall rig layouts, dimensions, equipment positions, working areas, access arrangements and interfaces.
Verification of structures, support arrangements, mechanical equipment details and installation interfaces.
Review of equipment arrangement, distribution interfaces, layouts and supporting technical documentation.
Confirmation of positioning, clearances, accessibility, maintenance space and interaction between adjacent equipment.
Verification of connection points, equipment interfaces, utility connections and integrated-system requirements.
Review of fabrication details against approved engineering intent, specifications and project requirements.
Drawing review with reference to contractual requirements, approved specifications and applicable standards.
Confirmation that final drawings accurately reflect the equipment and systems actually manufactured and installed.
Drawings are received, classified and checked against the project document register.
Engineering content is reviewed against specifications, layouts, data and project requirements.
Technical discrepancies, missing information and queries are formally documented.
Updated drawings are checked to verify that review comments have been properly addressed.
Drawings are confirmed for fabrication, installation, commissioning or as-built stage.
Accurate and coordinated engineering drawings are essential for successful fabrication, installation and operation.
Early technical review helps identify issues before they become physical problems in the workshop or at site, reducing project uncertainty and supporting smoother execution.
Drawing review can continue throughout OEM manufacturing, installation and final handover to maintain alignment between approved engineering and the asset actually delivered.
We review critical interfaces between different rig systems and equipment packages.
Structured revision review helps reduce the risk of teams using outdated or inconsistent drawings.
We consider whether the engineering can be practically fabricated, installed, maintained and operated.
Drawing reviews are performed with reference to relevant contractual requirements, approved project specifications and applicable industry standards.
Al-Etimad can provide structured drawing review, technical clarification, revision verification and final confirmation for your drilling asset project.
