What We’ve Accomplished Together
Tomsey Engineering & Services International Ltd successfully facilitated the Constructability Review Workshop for the Oben NAG Field Late-Life LP Compression Project, hosted by Seplat Energy Plc with participation from key project stakeholders including NNPC E&P Limited and the Nigerian Midstream and Downstream Petroleum Regulatory Authority (NMDPRA).
The workshop provided a structured platform to evaluate the project design from a construction perspective and identify potential challenges before the commencement of full-scale construction. As the independent facilitator, Tomsey guided the technical review sessions, bringing together multidisciplinary expertise to assess construction feasibility, execution requirements and opportunities for design optimization.
“During the workshop, stakeholders assessed the proposed design for construction feasibility and execution efficiency, while identifying potential construction risks, constraints and opportunities for optimization. The review also considered factors that could influence safety, quality, schedule and cost performance during project execution.”
Project Overview
Constructability is an important consideration in the development of major Oil & Gas projects, helping ensure that engineering designs can be safely, efficiently and practically executed in the field.
For the Oben NAG Field Late-Life LP Compression Project, the review considered potential construction risks, site and operational constraints, execution requirements and areas where the design could be optimized. Particular attention was given to factors that could affect safety, quality, schedule and cost performance during construction.
As a late-life field development, the project may involve interfaces with existing facilities and operational infrastructure. Reviewing these considerations during the design stage provides an opportunity to identify challenges early and incorporate practical solutions before construction begins.
Highlight Features
- Independent Constructability Facilitation
Tomsey provided independent facilitation of the technical review sessions, creating a structured platform for stakeholders to collaboratively assess the design and construction requirements. - Multidisciplinary Design Review
The workshop brought together key project stakeholders and technical disciplines to evaluate the design from different construction, engineering and operational perspectives. - Construction Risk & Constraint Identification
Potential construction risks, site constraints and execution challenges were identified and reviewed to help the project team address issues before full-scale construction. - Design Optimization Opportunities
The review provided opportunities to recommend practical improvements to the design that could enhance construction feasibility, safety, quality and execution efficiency.
The Results
- Improved Construction Readiness
The review provided the project team with a clearer understanding of construction requirements and potential constraints ahead of project execution. - Enhanced Safety & Risk Management
Early identification of construction-related risks supported recommendations aimed at improving safety and reducing potential hazards during execution. - Improved Schedule & Cost Performance
