Mechanical Maintenance Engineer – Heat Exchangers & Turnarounds

About Dolphin Dolphin Oilfield Equipment Services is an Abu Dhabi (Mussafah) industrial services company serving ADNOC group companies, EGA, Borouge and other oil & gas, power and industrial clients across the UAE. We manufacture, service and retube heat exchangers, execute EPC-stage site works — structural, piping, equipment installation — and deliver shutdown and turnaround maintenance campaigns onshore and offshore. The Role We are hiring a Mechanical Maintenance Engineer to own heat exchanger servicing and shutdown/turnaround execution: retubing, tube plugging, bundle repair, cleaning and testing in our Mussafah workshop, plus site campaigns — bundle pulls, on-site piping jobs and valve replacement — inside client turnaround windows, onshore and offshore. You will run work under our long-term heat exchanger maintenance agreements with ADNOC group companies, EGA and Borouge, and on refinery and offshore turnaround campaigns. What You Will Do • Own heat exchanger servicing jobs end-to-end: receipt or site inspection, repair scoping, execution, testing, documentation, dispatch. • Inspect shell & tube bundles and produce as-found condition reports (photos, measurements, tube condition) within 24–48 hours; support quotations with quick man-hour and material estimates. • Execute retubing, tube plugging, bundle repairs, gasket replacement, mechanical/chemical cleaning, and hydrostatic/pneumatic testing. • Deliver shutdown and turnaround (STO/TAR) scopes: bundle extraction to box-up, site piping and valve installation/replacement inside the outage window. • Make repair-vs-replace recommendations; document and secure client approval for scope growth once units are opened. • Lead supervisors, technicians and multinational crews across day/night shifts; mobilise at short notice. • Own quality documentation: ITPs, dimensional and test records, as-found/as-left reports and final dossiers. • Work to permit-to-work, confined-space and client HSE requirements on ADNOC-type sites. What We Are Looking For • B.Eng. in Mechanical or Maintenance Engineering — hands-on capability weighs more than paper qualifications. • 3–7 years in heat exchanger servicing, static equipment maintenance or turnaround contracting. • Practical shell & tube experience: retubing, tube plugging, bundle repair, leak and pressure testing. • Site experience with piping jobs and valve installation/replacement. • Shutdown/turnaround experience in refinery, gas plant or petrochemical environments; confident in PTW and confined-space culture. • English confident enough for client-facing site communication and reporting. Preferred / a plus: • TEMA nomenclature, API 660/661 awareness; plate heat exchanger (PHE) refurbishment exposure. • Valid ADNOC site passes/inductions; offshore experience. • Estimation exposure (pricing repair scopes); night-shift crew leadership. What We Offer • One of the UAE's busiest heat exchanger workshops, with long-term maintenance agreements across the ADNOC group, EGA and Borouge — steady work between turnaround seasons. • Onshore and offshore turnaround campaigns — high-intensity, high-responsibility site work with real client exposure. • Variety: service jobs run days to weeks, several at different stages — never one long identical project. • Competitive salary and benefits per UAE labour law; immediate start available. Working Pattern — Read Before Applying Honest note: during shutdown seasons this role means night shifts, extended hours, consecutive working days and mobilisation on under 48 hours' notice, across the UAE and to Oman/Qatar. Between campaigns you are workshop-based in Mussafah. If you want a predictable calendar, this is not your role; if you like intense campaigns followed by quieter workshop periods, it is.
