Question 1

The challenge

Accepted Answer

A marine construction and dredging business 
supporting an LNG development project along 
the Gulf Coast required reliable temporary power 
to operate electrically driven dredging pumps.
With no permanent utility power available, the 
operation depended on a solution capable of 
sustaining high load pumping over long distances 
to move material several miles from site. The 
project carried demanding operational 
requirements, with extended runtime needs and 
tight alignment to broader construction 
schedules. As timelines accelerated, the 
customer also needed early access to power for 
one pump while the wider installation was still 
underway, creating an urgent requirement for 
interim generation support during mobilization.

Question 2

The solution

Accepted Answer

Aggreko engineered a temporary natural gas 
power solution using 1500 kW generators, 
electrical distribution, cabling, and load bank 
support to meet the site’s sustained pumping 
requirements. Natural gas generation from the 
site supported long-duration operation and 
aligned with the project’s planned load profile. 
The system was designed to integrate with the 
dredging operation’s electrical demand and 
provide flexibility as site requirements evolved 
during mobilization. Installation included staged 
deployment of generation assets and distribution 
infrastructure to support commissioning activities. 
To address an early start requirement during the 
installation phase, our experts deployed a virtual 
pipeline to supply power to a single pump while 
the full system was being completed on site.

Question 3

The impact

Accepted Answer

The solution gave the customer a reliable way to keep 
dredging operations moving without permanent utility 
power, avoiding costly downtime and protecting project 
continuity on a 16-month schedule. By running on a natural 
gas-based strategy and rightsized temporary generation, 
the customer achieved significant fuel and operating cost 
efficiencies, delivering millions in savings over the course of 
the project. What also set this deployment apart was 
Aggreko’s end-to-end support model. With 24/7 coverage 
from standby technicians and remote monitoring capability, 
the system was continuously overseen and optimized in real 
time, reducing risk and ensuring consistent performance in 
a high demand marine environment. The combination of 
engineered power design and technical support gave the 
customer confidence to focus on production, not power 
constraints.
