Burckhardt Compression boosts European energy security with FSRU compressor overhauls
The FSRU received a new lease of life F
loating storage and regasifi cation units (FSRUs) are a cost-eff ective method to safeguard natural gas supply,
and recently, they have proved an eff ective temporary measure for many European nations. Helping to support regional energy
security, Burckhardt Compression conducted time sensitive compressor overhauls for two FSRUs on behalf of a leading maritime energy fi rm, ensuring that the revitalised vessels were fully ready to deliver this essential resource. Although reducing reliance on
pipelines is essential for European energy security, many countries do not have adequate capacity at liquifi ed natural gas (LNG) terminals for import, export and storage. Until these facilities are built, off shore FSRUs are functioning as a stopgap, delivering LNG that will power homes and businesses.
CRUCIAL COMPRESSOR MAINTENANCE BEFORE DEPLOYMENT When a maritime fi rm was asked to station multiple FSRUs for European countries, its attention quickly turned to the Burckhardt Compression Laby 5LP250 compressors aboard two of its ships. Featuring a rated power of 2,000kW (2,680hp) and a maximum speed of 509rpm, the unlubricated units suck methane gas in at a pressure of 12bar (174psi) and discharge it at 101 bar (1,465psi). Due to limited operation of these

compressors in the past and vibration issues, the fi rm wanted the units to be inspected and overhauled as necessary ahead of their deployment. Trusting the superior engineering capabilities and compressor knowledge of the original equipment manufacturer (OEM), the customer contacted Burckhardt Compression to complete the works.
SERVICES THAT ARE UP TO THE CHALLENGE The project presented multiple challenges. First, one of the vessels was due to be operational within three months, putting pressure on the team to deliver on time. Due to limited compressor use, the scope of works was essentially unknown until initial inspections. Having studied the units in detail, Burckhardt Compression engineers discovered issues with the auxiliaries such as the electric motors and safety valves. Furthermore, the anti-vibration pads were rusted, which was placing additional stress on the compressors. Some compressor components also required replacement. A key reason Burckhardt
Compression was selected for the project was its ability to take a holistic approach to the entire compressor skid. This meant that the customer could benefi t from a full- service solution designed to promote the performance and reliability of the complete system. With the scope fi nalised,
Burckhardt Compression got to work.
Utilising its OEM capabilities and capacity, the team organised express manufacturing and delivery of replacement compressor components for the overhauls. Working with a partner, engineers quickly sourced new anti-vibration pads, while the overhaul of other auxiliaries was conducted with trusted subcontractors. Total oversight by fi eld service representatives ensured the highest safety and quality standards were adhered to during challenging work aboard. The company completed the works
on time, resulting in successful FSRU deployment with no delays. This was possible due to the company’s ‘one- stop-shop’ service philosophy, which simplifi ed and expedited all aspects of the project for the customer. New OEM quality components fi tted to the compressors ensured the best possible service life.
HOLISTIC SUPPORT FOR ENERGY SECURITY With energy security a cornerstone of European governmental policy, FSRUs will continue to support countries that are reacting to a previous over-reliance on pipelines. However, the eff ectiveness of these vessels – and therefore dependable gas supply – is subject to the reliability of onboard equipment. With the full-service capabilities of Burckhardt Compression, FSRU operators in downstream applications now have the holistic support they need to succeed.
