INCITIAS has been supporting our clients with the selection and design of mooring, riser and umbilical systems. Involving our team during the early development of the project, allows us to provide clients with a range of options and recommendations to facilitate the right decisions early in the project.  

Further to the mooring selection studies, INCITIAS also provides mooring analysis and design for offshore and nearshore floating systems according to classification rules and international standards.   

We also undertake mooring designs for smaller facilities, like a single point mooring, marker buoys and the installation analysis.  

The following provides an overview of types of mooring system INCITIAS has experience with: 

 

 

Single point moorings: 

  • Bangladesh FSRU disconnectable buoy mooring and riser analysis FEED 
  • Disconnectable soft yoke mooring analysis for an FSRU located in South Vietnam 
  • Decommissioning analysis of turret moored FPSO 
  • Calm buoy mooring analysis for iron ore slurry and conventional oil and ammonia export 
  • River marker buoy detail design 
  • Solomon Island overflow-mooring detail design 

 

Jetty:

  • Bid engineering of Sardinia FSRU mooring 
  • Luzon, Philippines, 185,000m3 FSU jetty and side-by-side mooring analysis 
  • Son My 2 Pre-FEED design of 170,000m3 FSU Jetty  
  • Jetty design and mooring analysis for small scale LNGCs in range of 5,000 to 35,000m3 
  • Offshore jetty mooring design for FSRU West Sulawesi 

 

Other systems:

  • 155,000m3 FSRU FEED spread mooring, riser, umbilical and side-by-side mooring analysis 
  • Bangladesh LNGC-FSRU side-by-side mooring FEED 
  • Myanmar temporary river barge mooring for LNG Easy LNG transfer barge concept and detail design 
  • Expert opinion on cyclone tug berth mooring 
  • Permanent strut mooring pre-FEED of 350m FLNG facility and 240m LPG facility.
