LNG Backup for Pipeline Interruptions

LNG, propane or diesel, and when each is right

LNG when the site burns natural gas and needs a like for like replacement. LNG is methane. Once regasified it is the same fuel the plant already burns, so burners, turbines and boilers run on their existing settings with no conversion, no retuning and no change to emissions permitting. For a facility that cannot afford a process interruption, this is usually the deciding factor rather than price.

Propane for shorter interruptions and smaller loads. Propane is simpler to store and faster to stage, and does not need cryogenic equipment. It is not methane, so equipment that burns natural gas needs orifice changes or a propane air blending skid to produce a gas the burners will accept. That is a well understood piece of engineering, but it is a conversion rather than a substitution.

Diesel where dual fuel equipment is already installed. If the generators or boilers already run on diesel as an alternate, diesel is the fastest possible answer because nothing needs adding. Where that equipment does not exist, diesel means new equipment and new storage, and it is usually the most expensive fuel per unit of energy of the three.

What usually decides it. Downtime cost per hour, not fuel cost per million Btu. A site losing six figures a day to an outage is not optimising the fuel bill; it is buying certainty about restart time and about whether the process runs unchanged. That is why the common arrangement is a standby contract covering LNG for the primary load, with a smaller propane or diesel reserve sized to cover the first hours before the first trailer arrives.

Plan it before you need it. The difference between a site with a standby agreement and a site without one is measured in days, not hours. Equipment has to be sited, connections made and the first load scheduled. A site arranging this during an outage is competing for supply with everyone else affected by the same event.

Planned outages

Utilities and pipeline operators schedule maintenance, hydrostatic testing, and integrity work that can cut service for days or weeks. A backup LNG system is engineered in advance, connected, and tested before the outage begins, so production never stops. This is the lowest risk way to handle a known interruption.

Unplanned outages and curtailment

Line strikes, equipment failures, and extreme weather curtailments arrive without warning. In those cases response time is everything. A provider with staged equipment and contracted LNG supply can have gas flowing again in days. Facilities with high outage costs often hold a standby agreement, which pre engineers the tie in and reserves equipment so mobilization starts immediately.

What determines coverage cost

Three things drive price: gas demand (which sets trailer count and delivery frequency), distance from the LNG source, and duration. A short planned outage at a mid size plant may need a handful of loads. A long curtailment at a large facility becomes a rotating delivery operation.

Choosing the best backup fuel

LNG fits where the site burns natural gas and needs a like for like replacement, with existing burners running unchanged. Propane fits shorter interruptions and smaller loads. Diesel fits where dual fuel equipment is already installed. Downtime cost per hour usually decides it. The common pattern is a standby arrangement covering LNG for the primary load with a smaller propane or diesel reserve for the first hours.
