Job description

With Aibel you have a chance to develop your career through a range of projects in renewables and oil and gas. We call ourselves Engineering Pioneers. Whatever our job is, we approach it with creativity, curiosity and a drive to find new and better solutions. First we imagine the future. Then we build it.

Job responsibilities:

• Report to, and provide support to the Engineering manager on assigned projects and report to Engineering Manager at the basis level.
• Act as the single point of contact for Weight Estimation and Weight Control within the project and support the project team during bids, concept, FEED, Detailed Engineering, Construction, Transportation, Installation and as-built phases of the project
• Preparation of weight control procedure/specification, weighing procedure, weight reporting formats, and Weight Control Reports (monthly/bi-monthly) in line with project specifications in the assigned project
• Establishing the NTE (Not to Exceed) weights of topsides modules of FPSO and defining COG envelope for each module (Weight Budget), considering the limitations on module lifting capacity, vessel stability and hull structural capacity based on the discussion with client and own the weight budget estimates.
• Realistic estimation of weights and COG of various disciplines for a specific project based on historical data (in the absence of any weight input from disciplines) and. Benchmark the estimated weights with historic projects.
• Collecting the weight data and COG from all the disciplines, checking to ensure all items are identified and reported including the future requirements, review the weight and COG data received from disciplines, creating, maintaining and updating the weight and COG database and issuing weight reports throughout the project duration.
• Verifying and validating the weight input and COG data received from disciplines and highlight any anomalies in the weight and COG or for any missing items, to the respective Discipline Lead Engineers.
• Monitor the weight data of engineering disciplines and alert the management and disciplines at right time if there is any significant change in weight or COG.
• Review the weight data and weight reports received from vendors and sub-contractors for its compliance with procedure, specifications and project requirements.
• Create awareness among engineering disciplines, about the impact of growth in topsides weight, contractual obligations on weight limits for topsides modules, initiate weight reduction programs, suggest ways for reducing topsides modules weight and balancing COG offsets.
• Establishing and maintaining a "weight forecast system" based on feedback from the engineering disciplines which identifies, handles and reports potential and approved design changes affecting weight and COG. Plan and supervise the performance of the physical weighing (if any). Ensure that these weighing is in accordance with contractual requirements
• Provide technical support to the project to obtain necessary approvals from the verification body / classification society or other applicable approving authorities, represent weight discipline in meetings, discussions, audits, verifications, workshops and technical reviews that relates to weight control and be responsible for closeout of actions identified as required.
• Continuously seek to improve discipline working methods and procedures and contribute actively to discipline development activities

Work experience requirements:

• Minimum 10 years of working experience in an engineering setup for upstream oil & gas projects (platforms & FPSO projects), thereof a minimum experience of 5 years in the capacity of a Senior weight control engineer.
• Prior work experience with medium/ large sized FPSO projects in the Oil and Gas sector with similar roles and accountabilities and possess an excellent understanding of weight management, weight estimation and weight reporting at various stages of project from concept to installation.
• Have an overview about the major systems in topsides, responsibilities of various engineering disciplines and excellent understanding about the weight contributions from various disciplines depending upon the specific function of a topsides module in an FPSO. He / She shall also have a thorough knowledge about the pre-services phases like fabrication, land transportation (load-out), sea transportation (transit) and lifting of an offshore project
• Worked in Brownfield and Greenfield offshore FPSO projects and should have an understanding about marine engineering activities.
• Experience in anticipating changes in weight and COG on the project and be able to offer solutions when challenges arise, in collaboration with the disciplines.
• MUST HAVE possess demonstrable experience in developing the weight control report of an FPSO project and also in actual weighing operations in yard / field.
• MUST HAVE experience in verifying and validating the weight input received from various engineering disciplines for consistency with the layout and to find out any missing or double counted items, any anomalies, clarify and quantify contingencies, margins and allowances in the weight estimates, while preparing the weight control reports.
• MUST HAVE experience in estimating topsides modules weight and COG based on the available preliminary information (without the actual weight input from engineering disciplines) and generating topsides weight control report

Qualifications:

• Bachelor's degree in Civil or Structural or Mechanical or Naval or other equivalent engineering specialisation.

Other skills:

• Excellent technical communication (oral and written) skills with proven ability to present technical issues to design teams, client technical authorities, and client's project management representatives and approving bodies.
• Possess a thorough understanding and knowledge of material grades of structural steel and piping in offshore projects, familiar with commonly used oil and natural gas industry standards such as, but not limited to, ISO, API, NORSOK and other relevant standards.
• MUST HAVE technical skills such as reviewing the 3D model (E3D/Navis) / layout drawings, MTOs, vendor drawings and documents, weight control procedures and weight reports from other contractors, in order to obtain weight input to prepare weight report.
