Major Revamp of Laby®-GI Compressor on FSRU
Golar Management Norway is one of the world’s largest independent owners and operators of LNG midstream infrastructure. They decided to deploy their FSRU (floating storage and regasification unit) vessel Golar Freeze with a new charterer who will deliver gas to Jamaica's sole power utility JPS. In order to meet the new process parameters, a major revamp of the existing Laby®-GI Compressor (used as minimum send-out compressor on board) was required under high time pressure.
„Thanks to the compressor revamp, we were able to repurpose our Golar Freeze vessel within the given tight time frame. The technical solution offered and subsequent project execution completely met
our expectations. Burckhardt Compression was proactive, available at the right time, with the right plan, the right offer and the right team. We really appreciated its rapid and flexible responses to unanticipated
situations.“Gabriele Pipitone, Vessel Manager,
