The posting

JOB SUMMARY:

As a lead engineer responsible for process and mechanical design of “Seawater Treatment Systems” like Ultrafiltration, RO and Sulphate Removal Unit for offshore (Platforms / FPSO), and onshore oil & gas facilities.

The role covers the full project lifecycle — from pre-bid and tender support, concept selection and technology selection, through FEED and detailed design, to fabrication follow-up, FAT, installation, commissioning and performance testing.

As the discipline technical authority for the water treatment packages, the Lead Engineer owns the process and mechanical design basis, leads and checks the work of a small squad of engineers and designers, and acts as the principal technical interface to clients, EPC contractors, class societies and vendors.

KEY RESPONSIBILITIES:

  • Design of RO, UF, and SRU (Sulphate Removal) packages for onshore, platform and offshore FPSO facilities.
  • Develop PFDs, P&IDs, mass/heat balances, and hydraulic calculations.
  • Preparation of Process datasheets for Equipment and Instruments.
  • Preparation of Process Philosophies like Control, Startup/Shutdown, and Operation /Maintenance philosophies.
  • Size membranes, skids, pumps (booster/HP), vessels, and piping for offshore facilities with considering weight/space constraints.
  • Select materials for corrosive seawater service and chemical compatibility.
  • Identifying all client's comments and communications, to ensure client's comments / requirements are implemented, as well as feedback to project management and commercial team, raise trends / potential change orders, as necessary.
  • Review vendor documents and provide comments to ensure the vendor design is in line with the project requirements.
  • Prepare technical specifications, datasheets, and MTOs per client/EPC standards (API, ASME, NORSOK, ISO)
  • Review vendor packages (membrane suppliers, skid fabricators and etc.,) and co-ordinate HAZOP, Model Review, FAT, SAT and etc.,
  • Interface with piping, structural, E&I and layout teams for skids and module integration.
  • Prepares training manuals and owner’s manuals for on-site training.
  • Provide and prepare input to operating manual, pre-commissioning and commissioning manual.
  • Contribute to weight / space optimization studies for skid and modules
  • Understand the project & client’s contractual requirements and scope of work. Clarify scope of work and supply to form the contract basis with client.
  • Establish and own the design basis, process design criteria and equipment sizing basis for each package; verify and approve calculations produced by the squad.
  • Perform and check mechanical design of package equipment — pressure vessels and membrane/filter housings (ASME VIII Div. 1), skid structural arrangements, lifting and sea-transport load cases, nozzle orientation, piping layout and flexibility inputs, and rotating equipment selection.
  • Prepare and review mechanical datasheets and specifications for HP/booster pumps, dosing and chemical injection packages, cartridge filters, media filters, hydrocyclones, heat exchangers, blowers and CIP units.
  • Ensure compliance with class and regulatory requirements for offshore packages (DNV, ABS, Lloyd’s Register), flag/coastal state rules and marine warranty requirements.
  • Lead and participate in HAZOP, HAZID, SIL, SAFOP and 3D model reviews (30 / 60 / 90%); close out actions and maintain the action tracking register.
  • Plan and control discipline man-hours, deliverables and schedule against the budget; report progress, risks and trends to the Project Manager and Engineering Manager.
  • Mentor, coach and technically supervise junior process and mechanical engineers and designers; act as discipline checker / approver for squad deliverables.
  • Support FAT, SAT, pre-commissioning, commissioning, start-up and performance / guarantee tests; troubleshoot process upsets such as membrane fouling and scaling, flux decline, differential pressure rise and off-spec permeate quality.
  • Drive standardisation of package designs, capture lessons learned and contribute to continuous improvement of in-house design tools, typicals and specifications.

PRE-BID, TENDERING AND PROPOSAL SUPPORT:

  • Review ITT / ITB packages, client specifications and scope of work; identify technical risks, scope gaps and cost drivers, and prepare the deviation / exception and technical clarification registers.
  • Develop conceptual and FEED-level process design for bids — water balance, membrane projections (WAVE, IMSDesign, ROSA, Toray DS), preliminary PFDs, equipment lists, process descriptions and control philosophies.
  • Produce preliminary equipment sizing, skid weights, footprint and layout envelopes, and utility / chemical consumption figures — critical for weight- and space-sensitive offshore and FPSO topside bids.
  • Issue RFQs to membrane suppliers, package vendors and skid fabricators; run technical bid evaluations (TBE) and recommend the most competitive compliant technology and vendor.
  • Prepare MTOs, engineering man-hour estimates and the basis of estimate to support the commercial team in pricing, and highlight assumptions, qualifications and risk allowances.
  • Write the technical volume of the proposal — technical narrative, method statements, design philosophies, deliverables list, execution plan, organisation chart and schedule inputs.
  • Present and defend the proposed solution in bid clarification meetings and technical presentations with clients and EPC contractors.
  • Support post-tender negotiation and technical alignment, and lead a structured hand-over of the bid basis to the execution team at contract award.
  • Support business development with feasibility studies, budgetary proposals, technology comparisons and client technical presentations.

TECHNICAL SKILLS, SOFTWARE AND STANDARDS:

  • Process simulation and hydraulics: HYSYS / UniSim / PRO-II, AFT Fathom, PIPENET or equivalent.
  • Membrane projection software: WAVE, IMSDesign, ROSA, Toray DS or similar.
  • Mechanical and layout tools: AutoCAD, PV Elite / COMPRESS, and familiarity with 3D model review in Navisworks, E3D / PDMS or SmartPlant.
  • Working knowledge of API, ASME (Sec. VIII Div. 1, B31.3), NORSOK, ISO, NACE / MR0175 and class society rules.
  • Strong technical writing skills in English for specifications, philosophies, proposals and client correspondence.

REQUIRED QUALIFICATIONS:

  • Extensive knowledge and experience in overall water and wastewater treatment processes.
  • Experience leading and managing teams in a water and wastewater or similar operational environment.
  • Extensive experience in Industrial water and wastewater treatment operations and process management.
  • At least 10+ years of relevant experience in industrial water/wastewater treatment.
  • Experience in FEED, EPC Engineering and Packages, preferably in Water, FPSO and Oil & Gas Industry.
  • Experience in the Oil & Gas / Offshore industry is a plus.
  • Experience in the design of complex skid-based industrial water treatment systems.
  • Willing to travel
  • Able to multi-task and able to work in a fast-paced environment.
  • For the Lead position, 10+ years of relevant experience is preferred, including at least 3 years in a lead or discipline-lead capacity on FEED, EPC or package projects.
  • Demonstrated pre-bid / proposal engineering experience, including technical bid evaluation, cost and man-hour estimation and client-facing clarification meetings.
  • Hands-on offshore / FPSO topside package experience with weight- and space-critical design is strongly preferred.
  • Degree in Chemical, Process, Mechanical or Environmental Engineering; Professional Engineer or Chartered Engineer status is an advantage.
  • Strong interpersonal and client-facing communication skills, with the ability to lead a multi-disciplinary and multi-cultural team.
  • Based in Singapore or willing to relocate; existing eligibility to work in Singapore is an advantage.
  • Valid BOSIET / offshore medical certification is an advantage for site and offshore visits.

REPORTING AND KEY INTERFACES:

  • Internal interfaces: Sales and Proposals, Project Management, Procurement, Piping, Structural, E&I, QA/QC, Site and Commissioning.
  • External interfaces: clients, EPC contractors, vendors and sub-suppliers, third-party consultants and class societies.
