Winch / Crane Mechanical Design Engineer

Key Responsibilities Mechanical Design & 3D Modeling: Design mechanical components, drum structures, level-wind spooling mechanisms, gearboxes, shafts, drive lines, and skid frames using 3D CAD tools (SolidWorks, Inventor, or Creo). Calculate drum holding capacities, wire rope layering behavior, dynamic torque requirements, and line pull forces. Structural & FEA Stress Analysis: Perform analytical hand calculations and Finite Element Analysis (FEA) to ensure structural integrity and fatigue resistance under extreme dynamic loads. Optimize weight-to-strength ratios for marine/offshore environments. System Integration: Select and integrate drive trains, planetary gearboxes, hydraulic motors/power units (HPUs), electric drives, brake systems, slip rings, and sensor interfaces. Work alongside electrical and hydraulic controls engineers to ensure seamless electro-hydraulic/electric winch control. Class Certification & Compliance: Ensure all engineering designs conform to marine class rules (DNV, ABS, BV, API 2C, ISO). Prepare structural design reports, engineering dossiers, and calculation books for third-party class approvals. Manufacturing & Technical Documentation: Prepare detailed production assembly drawings, piece-part manufacturing drawings, weld symbols, machining tolerances, and comprehensive Bills of Materials (BOMs). Support shop floor fabrication, assembly, machining, and material selection (corrosion-resistant coatings, structural steel grades, high-strength alloy steels). Testing & Field Commissioning: Draft Factory Acceptance Test (FAT) plans, proof load testing procedures, and line pull/brake test specifications. Provide technical assistance during shop assembly, FAT execution, troubleshooting, and field commissioning.
