Draftsman - Offshore Projects

Job Summary

The Draftsman – Offshore T&I will be responsible for producing detailed engineering drawings and design deliverables supporting the transportation, load-out, sea-fastening, and installation of offshore structures such as jackets, topsides, modules, subsea structures, and pipelines. The role requires close coordination with T&I engineers, marine warranty surveyors, and fabrication yards to ensure drawings meet project specifications, classification society requirements, and offshore industry standards.

• Prepare detailed 2D/3D drawings for load-out, transportation, sea-fastening, lifting, and installation of offshore structures (jackets, topsides, modules, decks, piles, subsea equipment).
• Develop rigging arrangement drawings, padeye details, spreader bar/frame drawings, and grillage/sea-fastening layouts based on engineering calculations.
• Produce barge and vessel deck layout drawings, including ballast arrangement references and stability-related sketches as directed by engineers.
• Prepare skidding, jacking, and float-over arrangement drawings where applicable.
• Generate as-built drawings and redlines based on site markups and fabrication feedback.
• Coordinate with structural, naval architecture, and marine engineering teams to incorporate design changes accurately.
• Maintain drawing registers, revision control, and ensure all drawings comply with company and client drafting standards.
• Support preparation of installation procedures, method statements, and technical drawing packages for marine warranty survey (MWS) approval.
• Liaise with fabrication yards and site teams to resolve drafting queries during construction and load-out phases.
• Ensure drawings comply with relevant codes and standards (e.g., DNV, ABS, Noble Denton/MWS guidelines, client specifications).
• Participate in design reviews and provide drafting support during HAZID/HAZOP or engineering review meetings, as required.

• Diploma or Degree in Mechanical/Structural/Naval Architecture Engineering, Drafting, or related technical field.
• Minimum 3 years of drafting experience in offshore oil & gas, marine, or heavy lift/T&I projects.
• Proven experience producing sea-fastening, rigging, and load-out drawings for offshore structures.

• Proficiency in AutoCAD (2D/3D); experience with Tekla, SP3D, PDMS, or similar 3D modeling tools is an advantage.
• Familiarity with structural steel detailing and marine/offshore drafting conventions.
• Working knowledge of offshore T&I engineering principles: lifting, transportation, sea-fastening, and installation methods.
• Ability to interpret structural calculations and engineering sketches to produce accurate detailed drawings.
• Understanding of classification society and marine warranty survey (MWS) drawing requirements (DNV, ABS, Lloyd's Register, etc.).
• Competent in using Microsoft Office (Excel, Word) for drawing registers and documentation control.

• Strong attention to detail and accuracy under project deadlines.
• Good communication skills to coordinate with multidisciplinary engineering teams.
• Ability to work independently and manage multiple drawing packages simultaneously.
• Willingness to travel to fabrication yards or site locations as required.

• Prior experience with float-over, skidding, or jacking system drawings.
• Exposure to subsea structure or pipeline installation drafting.
• Experience working directly with Marine Warranty Surveyors (MWS) during document approval cycles.
• Familiarity with rigging/lifting equipment certification and load calculations.

• Primarily office/engineering environment with occasional site or fabrication yard visits during load-out and installation campaigns.
• May require extended hours during critical project milestones (load-out, sail-away, installation windows).
