Piping Tie-In Works in Singapore

Seamless Integration of New Pipelines into Existing Systems

Seamlessly Integrating New Pipelines into Existing Systems with Precision and Safety

At ATM Engineering Pte Ltd, we specialize in high-quality Piping Tie-In Works that ensure smooth integration of new piping systems into existing infrastructure—without disrupting operations. Whether it’s a live plant modification, shutdown requirement, or brownfield expansion, we bring precision, expertise, and safety-first execution to every project.

Our experienced team has successfully executed tie-in works across multiple sectors including Oil & Gas, Petrochemical Plants, Chemical Process Facilities, and Water Treatment Plants—primarily in Jurong Island, Tuas, and Bukom Island.

What Are Piping Tie-In Works?

Piping Tie-Ins are critical connection points where a new pipeline system is integrated into an existing one. These are highly technical operations that require thorough planning, detailed isometric drawing reviews, and accurate cut-in, welding, and inspection work.

When done right, a tie-in creates a seamless flow transition without compromising the mechanical integrity of either the new or existing system.

Our Piping Tie-In Capabilities Include:

✅ Hot Tapping and Cold Cutting
✅ Precise Line Isolation and Blinding
✅ Shutdown & Non-shutdown Tie-ins
✅ Isometric Drawing Review and Site ark-ups
✅ Spool Fabrication, Erection & Hydrotesting
✅ NDT (Non-Destructive Testing) & QA/QC Compliance
✅ Pipe Support Fabrication and Installation
✅ System Flushing and Leak Checks

Why Choose ATM Engineering for Tie-In Works?

✔ Technical Expertise: Our pipefitters and welders are experienced in handling tie-ins under live-plant and shutdown conditions with a focus on minimizing downtime.

✔ Safety-Driven Approach: We follow strict Permit-to-Work (PTW) procedures and are well-versed in working within high-risk zones, including confined spaces and hazardous environments.

✔ 3D & Isometric Understanding: Our engineers are capable of interpreting and adjusting to site conditions, modifying routes and supports without compromising engineering intent.

✔ Coordination Excellence: We work closely with main contractors, project engineers, and plant operations teams to ensure zero conflicts and 100% integration accuracy.

📍 Our Experience

We’ve carried out multiple tie-in works for clients such as Shell, PCS, Vopak, and more—both during shutdowns and ongoing operations. Our projects often include retrofit upgrades, capacity expansion tie-ins, and emergency pipe rerouting.

✅ Safety is Our Priority

We conduct detailed Risk Assessments (RA), Method Statements, and Toolbox Talks before every tie-in. With safety certifications, confined space permits, and real-time supervision, we ensure zero incidents and full compliance.

Frequently Asked Questions (FAQ)

Yes. We are fully equipped to perform live tie-in works with proper isolation, hot tapping, and shutdown coordination if required.

We serve Oil & Gas, Chemical Plants, Power Generation, and Water Treatment Facilities throughout Singapore, especially on Jurong Island and Tuas.

The duration of a tie-in project depends on several factors including the size of the piping, working environment, and whether it's done during a plant shutdown or live operation. On average, small-scale tie-ins can be completed within a few days, while larger or high-risk tie-ins may take weeks of planning and phased execution.

Our team comprises certified welders (ASME/BS EN standards), confined space trained personnel, and WSQ-certified supervisors. We also conduct continuous internal safety and technical training to ensure that everyone is up-to-date with Singapore’s industry safety regulations and client-specific requirements.

Absolutely. We provide complete Quality Assurance & Quality Control documentation, including welding reports, NDT results, hydrotest records, material traceability, and as-built drawings. All documentation is compiled in compliance with client specifications and MOM requirements.
