Sector 02
LNG, FSRU & Cryogenic Infrastructure
A focused practice across the LNG value chain — anchored by a cryogenic-piping capability few boutiques hold. LNG import terminals, FSRU conversions, cryogenic stress engineering for low-temperature service, and marine interface for berthing, offloading and ship-to-ship transfer.
Capabilities
LNG Terminals & Jetty Structures
- LNG import and regasification terminal — jetty structures, structural design
- Jetty and marine-loading structure design — PIANC / BS 6349
- Cryogenic piping systems — ASME B31.3 low-temperature service, cold box, LNG lines
- Shore approach and berthing structure — trestle, dolphin, fender structures
FSRU Conversion & Integration
- LNG carrier → FSRU conversion — feasibility, FEED, regas and BoG integration
- FSRU mooring and station-keeping — OCIMF MEG4, OrcaFlex time-domain analysis
- Hull-topsides integration — cryogenic load transfer, thermal movement
- Hull structural integrity management and life extension
Marine Interface & STS Operations
- Berthing analysis and fender sizing — LNG jetties, PIANC
- Ship-to-ship (STS) LNG transfer — SIGTTO, cryogenic hose interface
- Cryogenic hose and loading arm interface
- Offloading operability — weather-window and marine-operations analysis
