- Gas, Offshore and Subsea projects.
- Prepare models for PLEMs (Pipeline End Manifolds), PLETs, offshore platforms, structural skids, subsea frames, riser supports and clamps.
- Model structural steel members, plates, stiffeners, brackets, gussets, lifting points and equipment supports.
- Develop detailed models of Riser Clamps, Pipeline Clamps, Flanges, Hub/Flange interfaces, supports and associated components.
- Prepare models based on engineering calculations, design sketches, client drawings and technical specifications.
- Generate GA drawings, fabrication drawings, assembly drawings, sections and detailed views from approved 3D models.
- Develop fabrication details including plates, weld locations, bolted connections, interfaces and machining requirements based on engineering inputs.
- Ensure correct dimensions, tolerances, elevations, coordinates and interface points.
- Incorporate Engineer,



Client and Third-Party review comments into models and drawings.
- Coordinate structural interfaces with piping, pipeline, mechanical and subsea engineering teams.
- Identify clashes, interface issues and fabrication constraints during modeling.
- Support engineering and fabrication teams by providing accurate drawings and model information.
- Maintain proper drawing/model revisions and document control requirements.
- Perform self-checking of models and drawings prior to submission.
