Overseas and Offshore Services

JEM provide experienced Service and Commissioning engineers for project, Operations & Maintenance work also Supervisory positions if required. All engineers are supported by a dedicated team at our UK North West based office. Our engineers are familiar with permit to work systems, paper or ISSOW and have current offshore survival and medical certificates.


To maintain efficiency all compressors should have basic maintenance carried out based upon run hours or performance. The oil and filters should be changed, and the receivers drained. In addition the pneumatics and mechanics of the compressor should be checked and adjusted as necessary in compliance with the original engineering manufacturer. JEM can provide this service for you.

Controller and Alarm Systems

JEM is a supplier and installer of fully automatic and manual control / starting equipment for both diesel and electric drivers, employed for all types of applications. We install panels compliant with the latest LPCB, FM & NFPA requirement for fire pump use, or tailor-made packages with all of the relevant alarms and monitoring systems for industrial pump usage.

We can provide 12 volt or 24 volt systems, dependant on the capacity of the engine. For electric motors, we offer star delta or direct on-line high voltage panels. Replacement of control systems is our specialty, and where required we can interface new controllers with existing drivers.

Due to the high level of expertise JEM has gained over many years, we have the ability to undertake repair work on obsolete fire fighting products that still exists where the original engineering manufacturer is no longer trading.

Diesel and Motor Drivers

Diesel engines and Electric motors are often removed in order to carry out extensive repairs. It can sometimes prove to be cost effective to carry out a major overhaul of these drivers (especially on the older packages). Injector and fuel pump calibration is essential to the efficient operation of a diesel unit.

The JEM service centre has the facilities to repair most makes of engine (regardless of age). We can overhaul and repair most makes of injectors and fuel pumps, and Electric motors can also be overhauled or replaced with new.

Bladder Tanks

JEM has been active for many years in the maintenance and replenishment of both horizontal and vertical foam bladder tanks. There is a severe risk of rupture when filling the bladder and end users need to be assured that the system will operate satisfactory when required.

The bladder tank is a mechanical device that requires periodic inspection, and annual maintenance is strongly recommended to ensure that any defects are found and corrected. We are specialists in this area.

Emergency Generators

JEM Engineers can fully service your Emergency Generator (temporary or permanent) and in addition our approved subcontractor can carry out on site load testing.
