TIE-IN PROJECT WORKS

SERVICE DESCRIPTION

The term ‘Tie-in’ is generally used to describe the connection of a pipeline to a facility, to other pipeline systems or the connecting together of different sections of a single pipeline. Furthermore it can be defined as a welded joint that cannot be carried out by the main front end welding/production during the main line laying. These projects are usually required within a specified time frame without causing inconvenience to the operation schedule.

 

Alstern Technologies Singapore provides a synergy based on our individual services scope and offer to our clients a complete tie-in project execution. This service include preparatory works (e.g. in-house fabrication and on-site installation), setting-up works, tie-in operations and post tie-in operations.

OUR CAPABILITIES

With the broad range of pipeline services we render, Alstern Technologies Singapore is capable of offering the most cost-effective solutions to meet our customers requirements.

 

Starting with the project proposal, we would offer a solution while working within the constraints of project requirements. Our project team has vast experience and the technical expertise to propose suitable solutions to maximize operation uptime.

 

During the project preparatory stage, we offer NDT Surveys including leak detection, corrosion detection, pipe thickness measurements, flow measurements, thermal imaging, x-ray and ultrasonic surveys. Fabrication works are also performed in-house under strict supervision with traceability including weld numbering.

 

Being a pipeline solutions provider, we have a team of dedicated tie-in operations crew that work with the clients, consultants and project managers to perform tie-in operations including pipe freezing, hot tapping, line stopping, by-pass services, leak sealing, etc.

 

As a one-stop service provider, we also cater to the post tie-in activities such as NDT inspections on welds, joint and pipe coatings and pipeline insulation works.

 

At Alstern Technologies Singapore, we believed in providing cost-effective one-stop pipeline solutions to our customer while minimizing operation downtime (or maximizing asset uptime).
