Job summary

Surbana Jurong is seeking a (Senior) Mechanical Engineer specializing in rotating equipment and pumping systems for hydrocarbon, water and seawater services. The role spans feasibility through commissioning across energy projects, including power generation, fuels, terminals and coastal engineering.

The engineer will handle pump sizing, equipment specifications, bid evaluations and vendor reviews, working with multidisciplinary teams on site and in offices.

Qualifications

• Bachelor's degree (Hons) in Mechanical Engineering from a recognised university.
• A master’s degree or postgraduate qualification in mechanical engineering will be an added advantage.
• Minimum eight (8) years (Senior Mechanical Engineer) of experience in conceptual, FEED and detailed engineering for mechanical, rotating equipment and pumping systems in power, oil & gas, petrochemical or water infrastructure projects.
• Experience in a range of pump technologies and applications, including hydrocarbon process and transfer pumps, large vertical seawater and cooling-water pumps and concrete volute pumps.
• Experience in seawater intake and outfall systems, or cooling water systems for power plants and/or refinery/petrochemical plants and/or coastal engineering projects.
• Conversant with relevant international and local codes, standards and practices (e.g. ANSI/HI, ISO 9906, API 610 / ISO 13709, ASME) for pumps and mechanical equipment.
• Experience in pump installation, alignment, vibration monitoring, testing & commissioning and operation & maintenance will be an added advantage.
• Strong written and verbal communication skills and interpersonal skills.
• Strong analytical skills and ability to solve problems independently.
• Team player with the ability to work with and manage clients and contractors.

Responsibilities

• Independently carry out feasibility studies, conceptual design, basic engineering, FEED and detailed engineering for mechanical works – rotating equipment and pumping systems.
• Independently prepare and review key project documentation to execute the complete mechanical engineering scope of work in accordance with project requirements and customer expectations.
• Perform pump sizing and selection, including system hydraulic calculations, system resistance curves, NPSH and submergence checks, and analysis of operating points and parallel pump operation.
• Develop specifications and data sheets for seawater cooling pumps (e.g. vertical wet-pit, mixed-flow and concrete volute pumps).
• Coordinate pump intake and sump design with civil/structural and process disciplines in accordance with Hydraulic Institute guidelines, including review of physical or CFD hydraulic model studies.
• Specify materials of construction suitable for seawater service, taking into account corrosion, erosion, biofouling control and cathodic protection requirements.
• Coordinate transient (surge/water hammer) analysis of cooling water systems and recommend surge protection measures.
• Prepare mechanical equipment lists, material take-offs (MTOs) and technical bid evaluations for vendor packages.
• Review and comment on vendor and EPC design documents, including pump performance curves, rotordynamic and vibration analyses, structural interface loads and installation procedures.
• Review and comment on construction activities, and witness FAT/SAT and commissioning activities.
• Supervise the fabrication, installation, pre-commissioning and commissioning of mechanical equipment.
• Prepare work progress reports and submit them to senior team members for review and approval before issuing to owners and other parties for approval.
