Crestchic provided a 4.5MVA load bank solution as part of a £16m refurbishment programme for the Royal Navy’s premier repair vessel, the RFA Diligence.
Client : Seaking Electrical
Location: Birkenhead, UK
Requirement: 1x 20ft 6MVA Load banks
2x 2.9MVA Transformers
“The Vessel has a diesel-electric drive; five Nohab-Polar diesel generators; four NEBB motors; one propeller; two 360 degrees azimuth thrusters and two bow thrusters. We were contracted to supply load bank equipment for the testing of the vessel’s generators.”

RFA DILIGENCE (A 132), the Royal Navy’s premier repair vessel, which has seen active operations throughout the Falklands and Gulf wars, is undergoing a £16m refurbishment plan, of which Crestchic Limited, the fast growing load bank specialist, has successfully provisioned a 4.5MVA load bank test on the vessel’s 2.52MW Wartsila generators.
The load requirement saw Crestchic transport a 20ft 6MVA load bank and two 2.9MVA Transformers operating a 6kV 60Hz, 3-phase system to the Birkenhead dockyard, where the vessel currently resides while it undergoes the major refurbishment plan.
“The Vessel has a diesel-electric drive; five Nohab-Polar diesel generators; four NEBB motors; one propeller; two 360 degrees azimuth thrusters and two bow thrusters,” said Jo Price, Rental Manager at Crestchic Limited. “We were contracted to supply load bank equipment for the testing of the vessel’s generators.”
“Prior to the start of the two week testing schedule, we installed both low and medium voltage cabling and ensured the load banks achieved a resistive and resistive reactive capability at 0.8PF and stepped load increments up and down 1kW/1kVA, allowing for the incredibly accurate application and rejection of load.
“The Diligence has seen some heavy use over the last 25-years, being used as a support ship for submarines in the Far East and has had the longest deployment of any RFA ship in recent times, which makes our job even more crucial to the continued success of the vessel.”
Crestchic is a dedicated manufacturer and retail supplier of load bank packages, which are available from 30kW to 100MVA. Boasting high profile clients from every corner of the globe, Crestchic is leading the way in load bank solutions for the power generation, oil and marine sectors.
“We also had an engineer on site to install, operate and monitor the load bank tests,” continued Price.
Operating from multiple bases in the UK, Europe, US and the Far East, the company has garnered an excellent reputation for its high levels of quality and service.

WHY USE A LOAD BANK?
Load banks are primarily used for testing electrical power output on diesel generators, gas turbines and UPS systems whilst carrying out commissioning and maintenance work.
The load banks are used for simulating real electrical loads enabling essential setup and commissioning which ensures that all electrical and control parameters are met prior to power generation/back up equipment being energized on line.
