Custom-designed Containerized Power module

About the project

The project aimed to improve the stability of the local electricity network in Lowestoft, UK, while enhancing grid resilience and meeting specific client requirements. It also needed to address excess heat generated during operation.

A custom containerized power module was developed using a Jenbacher J620 (6th series) engine with a capacity of 3 MW. The unit runs on natural gas, and excess heat is dissipated using rooftop dry coolers. The design ensures compactness, mobility, and ease of operation.

We designed and delivered a fully tailored power module with separate machine and control rooms. The container includes a chequer plate floor functioning as an oil containment sump and acoustic insulation for noise reduction. The system is built for safe, reliable, and easy maintenance.

Inside the Lowestoft Modular Power Project

The Layout

External

Exhaust Gas Silencer

A free-standing silencer with integrated catalytic converter elements. The engine’s frequency band, the required target levels, and the possible pressure drop are considered to reduce sound emissions.

Dry Cooler

Customized, horizontal design flat coolers to meet the engine requirements, ambient temperature, and noise restrictions. As for the power plant specification, the dry coolers are placed on the ground beside the containers.

Access ladder to roof and railing

Steel ladder and railings to provide access and safety during maintenance work and checkups of auxiliary equipment.

Gas connection flance

Connection point to the plant’s gas line.

Internal

Generator Set

Jenbacher J620 3MW engine.

Air inlet silencer

Series of sound-absorbing panels designed to limit the noise generated by the power module and allow an optimal flow of the combustion air in the engine room.

Air outlet silencer

Sound-absorbing panels are positioned to limit the noise generated by the power module and allow steady exhaust airflow.

Air supply fans

Engine room ventilation to ensure the discharging of the radiant heat from the unit and for combustion air supply to the engine.

Engine heating system

The engine heating system warms up the engine and keeps it at a ready-to-start temperature, ensuring faster engine starts and reducing engine wear.

Engine cooling system

The engine cooling system removes excess heat to maintain the engine operating temperature so it can work most efficiently.

Gas train

The gas train supplies the engine with gas and contains regulatory, measurement, and control elements.

Oil tanks

A tank for the storage of lubricating oil is installed in the container.

Control systems and panels

A user-friendly engine management system that provides engine management, monitoring, and control. All error messages are date stamped to identify the sequence of events.

Safety systems and equipment

Smoke alarm system with detectors in the machine and control room and a gas warning device in the machine room. Powder fire extinguisher in the control room.

Air temperature control system

Air temperature sensor in the machine room. Heating radiator in the machine room. Electric heating/cooling in the control room as well.
