Oil Spill Response During LNG Terminal Construction: What Is Often Overlooked?

Oil spill response planning for LNG terminal projects often focuses on long-term operations and regulatory compliance.

For a comprehensive overview of what oil spill response equipment is required throughout the entire LNG terminal lifecycle, you may also refer to Oil Spill Response Solutions for LNG Terminal Projects: What Equipment Is Really Required?


However, the construction phase presents a very different set of spill risks — and many of them are frequently underestimated or overlooked.

During construction, LNG terminals experience higher marine activity, temporary systems, and frequent equipment movement, making oil spill response readiness especially critical.


This article highlights what is often overlooked during LNG terminal construction, and how EPC contractors can better prepare for real-world spill scenarios.


Construction Phase Oil Spill Risks Are Different — and Higher

Unlike the operational phase, LNG terminal construction involves:

  • Multiple subcontractors working simultaneously
  • Temporary fuel storage and refueling operations
  • Frequent mobilization and demobilization of vessels
  • Heavy reliance on hydraulic equipment
  • Changing work zones and access points

These factors significantly increase the likelihood of small but frequent oil spills, which can quickly escalate if not managed properly.




Overlooked Issue #1: Temporary Fueling and Refueling Operations

One of the most common spill sources during construction is temporary fueling.

Unlike permanent fuel systems, temporary setups often involve:

  • Portable tanks
  • Flexible hoses
  • Manual connections
  • Inconsistent spill protection measures

Without proper containment and absorbents nearby, minor leaks can quickly reach water surfaces, especially at jetty or barge locations.

What should be prepared:




Overlooked Issue #2: Hydraulic Oil Leaks from Construction Equipment

Cranes, winches, pile drivers, and dredging equipment rely heavily on hydraulic systems.

During intensive construction:

  • Hoses are frequently stressed
  • Connections loosen over time
  • Small leaks often go unnoticed

Hydraulic oil spills are rarely dramatic — but they are persistent and difficult to clean if not addressed immediately.

Effective response includes:



Overlooked Issue #3: Delayed Deployment of Oil Containment Booms

Many projects assume that oil containment booms are only needed for major incidents.

In reality, early deployment during construction can prevent minor spills from spreading.

Booms are often overlooked because:

  • They are stored offsite
  • Deployment is considered “too slow”
  • Responsibility is unclear between contractors

However, even temporary boom deployment during high-risk activities can significantly reduce environmental exposure.


Many of these overlooked issues arise because construction-phase spill response is handled by EPC contractors under tight schedules and changing site conditions.

Overlooked Issue #4: Poor Placement of Spill Kits

Another common issue is that spill kits exist — but are not where they are needed.

Typical problems include:

  • Kits stored too far from work areas
  • Incomplete or mismatched contents
  • Workers unfamiliar with kit usage

During construction, spill kits must be:

  • Close to high-risk zones
  • Clearly labeled
  • Easy to transport by hand or vehicle

Fast access can mean the difference between a controlled spill and an environmental incident.



Overlooked Issue #5: Construction-to-Operation Transition Gaps

As LNG terminal projects move toward completion, attention often shifts to commissioning and handover — leaving spill response equipment in a gray zone.

Common gaps include:

  • Temporary equipment removed too early
  • Permanent systems not yet fully commissioned
  • Responsibility shifts between EPC and operator

A well-planned spill response strategy should bridge construction and operation, ensuring continuous coverage.


Best Practices for LNG Terminal Construction Spill Preparedness

Based on real project experience, effective construction-phase spill response planning should:

  • Address temporary and mobile risk sources
  • Combine containment, absorbents, and kits
  • Ensure equipment is deployable by construction crews
  • Adapt to changing site conditions
  • Remain active until full operational readiness


Final Thoughts: Construction Is Where Preparedness Matters Most

Oil spill response failures during LNG terminal construction are rarely caused by lack of equipment — they are caused by lack of planning for real-world conditions.

Recognizing and addressing overlooked risks during construction:

  • Reduces environmental exposure
  • Protects project schedules
  • Supports regulatory acceptance
  • Builds confidence for long-term operations
