Engineering Design and Fabrication (Onshore and Offshore)

SengS provides Engineering Services for the Onshore, Offshore and Subsea Markets. SengS Engineering services are provides from small studies to large detailed design projects.

Front End Engineering and Design (FEED) develops from a basic engineering package to a project package suitable for use as the basis for detailed design. The FEED will also provide cost estimation (+/- 20%).

Typical deliverable of FEED which will allow a decision to proceed with capital investment can be made:

  • Preparation of project equipment specifications
  • Preparations of major instrument & electrical datasheets such as, flow meters, choke valves and ESV
  • Development of Piping and Instrument diagrams and control philosophy
  • Development of Plant layout, including equipment location, pipe routing, walk ways etc.
  • Structural design (Topside and Subsea)
  • Design Reviews (HAZID, ENVID, HAZOP, RAM)
  • Procurement activities for major equipment items and long lead items

Following on from FEED, SengS can provide detailed design services which consist of developing the FEED into physical asset that achieves the detailed requirement of the project. Below are the typical deliverable of detailed design:

  • Finalisation of Piping and instrument Diagram for construction release
  • Preparation of piping isometrics for constriction including stress analysis
  • Preparation of power and control deliverables
  • Preparation of Power distribution and control systems for construction
  • Preparation of Civil/Structural construction drawings
  • Development of commissioning and operation documents
  • Technical support
  • Procurement of all equipment items

Brownfield Engineering

SengS has extensive experience of brownfield engineering for wide Variety of onshore and offshore facilities. This can consist of small modifications to major facility upgrades. To ensure downtime is minimal SengS strive to develop efficient engineering solutions to minimise offline time. This is down by utilising the latest survey techniques and tools to obtain accurate as built data of the physical asset. This approach minimises onsite modification and rework therefore reducing installation time, below details typical brownfield modifications:

  • Infill Well Projects
  • Retrofit Pigging Loops
  • Chemical injection modifications
  • Valve replacements
  • Reinstallation and replacement of pig launchers/ receivers
