Mozambiques LNG Umbilical Mooring Analysis

Project description:

• Mooring analysis consisting of 8 lines for 6 different locations along lay route.
• 4 flat seabed profiles and 2 sloped profiles with 1:3 slopes.
• Careful analysis around a reef area where Dyneema lines and mid-line buoys were used to reduce seabed contact.
• WD’s ranging from 2m at the nearshore to 100m at the laydown location.

OI’s scope of work:

Carry out detailed mooring analysis for umbilical lay providing:

• Mooring axial line tension and anchor loads under survival conditions (intact and SLF)
• Clearances from the obstacles or subsea pipelines/cables
• Vessel excursions
• Amount of line on the seabed
