Delivering Precision: Kingpost Integration for Shell Crux NNM Project

At S2NERGY PTE. LTD., complex offshore engineering challenges are opportunities to showcase our technical excellence and project management expertise. One of our standout undertakings is the EPC execution of the Kingpost Integration for the Shell Crux NNM Project—a project that demanded seamless coordination across engineering, procurement, and construction phases to support a major offshore development.

Project Overview

The Shell Crux NNM Project is a critical initiative aimed at developing offshore gas resources to support energy needs across the region. As part of this larger project, S2NERGY was entrusted with the design, fabrication, and installation of a specialized kingpost structure—a central component integral to offshore lifting and load management operations.

Our scope covered the full EPC cycle, delivering a turnkey solution that met Shell’s exacting standards for safety, quality, and performance.

Our Approach & Deliverables

1. Detailed Engineering & Design

The project commenced with comprehensive structural and mechanical design of the kingpost system. Leveraging advanced engineering software and our extensive experience in offshore structures, our team produced detailed analyses and optimized designs that ensured structural integrity, operational reliability, and compliance with offshore industry codes and Shell specifications.

Key deliverables included:

• Finite element analysis for structural performance
• Mechanical interface design for seamless integration
• 3D modeling and clash checks to ensure constructability
• Material selection aligned with offshore environmental demands

2. Shop Drawings & Fabrication Support
With design finalized, our focus shifted to manufacturing readiness. We developed precise shop drawings and provided comprehensive fabrication support to ensure smooth transition from design to production.

Our deliverables enabled:

• Accurate component fabrication and assembly sequencing
• Clear weld maps and material cut lists
• Rigging and lifting plans for safe handling during assembly
• Quality control procedures to ensure fabrication meets specification

3. EPC Execution – Engineering, Procurement & Construction

As the single-point EPC contractor, S2NERGY executed the full cycle of engineering, procurement, and construction of the kingpost structure.

Our team managed:

• Procurement of specialized offshore-grade materials and components
• Fabrication oversight ensuring adherence to schedule and quality standards
• On-site construction management, coordinating installation and integration with existing offshore systems
• Testing and commissioning, validating structural performance under operational conditions
