creation.

Your primary role will be to provide technical support to operating facilities, projects, technology deployment, and

talent development. This includes also conducting technical studies and assessments in stationary assets such as

mechanical calculations for piping, pressure vessel, shell and tube heat exchangers, air cooler fin fans, branch

reinforcement, hydrotest pressure, rating and/or de-rating, fitness for service to evaluate flaws or damage, pipe

stress analysis, flange calculations and perform nozzle calculations.

Duties & Responsibilities:

As the successful candidate you will be required to perform the following:

Perform field troubleshooting in a daily basis or as requested and participate on major T&Is and emergency plant

shutdowns. This includes providing engineering support to repair hydrocarbon leaks, review and approve the bolted

clamp calculations and design made by the specialized leak sealing contractors companies to maintenance prior to

field installation.

Provide support to maintenance support organizations and project executions by developing repair procedures or

just simply follow up on-going projects or repairs.

Perform piping mechanical calculations like minimum wall thickness for internal and external pressure, branch

reinforcement calculations, MAWP calculations as per ASME B31.3, hydrotest pressure, rating and/or de-rating of

piping circuits by following API 570, fitness for service to evaluate flaws or damage and determine if the piece of

pipe is suitable for continuous operation by using API 579, perform pipe stress analysis using Caesar II, perform

flange calculations as per ASME VIII Div 1 App 2 using PVElite, perform nozzle calculations using WRC-107 and WRC-

297 modeling the analysis in Caesar II or PVElite.

Perform pressure vessel calculations like minimum wall thickness for internal and external pressure, nozzle

reinforcement calculations, MAWP calculations, stability and buckling calculations for vessels to be PWHTed, rating

and/or de-rating of pressure vessels by following API 510, NBIC-23, ASME Code VIII Div 1 and/or 2 when applicable.

Perform shell and tube heat exchangers calculations as per TEMA standard, calculate tube sheet minimum thickness,

calculate minimum tube wall thickness, perform flow induced vibration calculations

Perform air cooler calculations and asses mechanical design as per API 661, perform mechanical assessment and

ligament efficiency calculations for tube sheet and plug sheet hole size enlargement as per ASME VII Div 1 App 13

by using PVElite

Perform Fire Heaters calculations like minimum wall thickness (Elastic and Rupture Creep) as per API 530. Perform

tube remaining life calculations and overall mechanical assessment of radiant/convection section tube supports,

perform mechanical calculations of fire heaters stack (Minimum wall thickness and Vibration and analysis)
