Mooring & Riser Analysis

The complex nature of offshore environment and the risk involved it becomes very important to correctly analyse and design any support system which has a significant effect on offshore safety and operation.

Vedam's in-depth technical expertise and industry knowledge has capability to undertake variety of complex projects :

Mooring Analysis of offshore work-cum-accommodation barges
Riser and Mooring Analysis
Pipelaying Analysis
General Line dynamics and motion prediction
Mooring Analysis

Mooring Analysis has become an essential tool to simulate complex nature of station keeping to ensure safety and to reduce risk during offshore operation. Mooring analysis is vastly required in case of:

Complex platform and sub-sea infrastructure
Vessel positioning in close proximity to assets
Longer mooring durations
Operational requirement: gangway connections, helicopter operations
Vessel response under accidental damage of a line
Support vessel's movement in close proximity to barge
Unconventional requirements: Connection to Jacket leg, DP buoys etc.
Mooring analysis for station keeping involves:
Motion Analysis and determination of RAO
Mooring Pattern Design
Quasi-static mooring analysis & catenary derivation
Code checking as per API/ISO/DNV
Damage case transient analysis
Mooring analysis can be wide varieties:
Spread mooring system for station keeping
Single Point Mooring or Turret System for floating compliant bodies
Mooring analysis for pipe laying or cable laying activities
Riser-mooring interference analysis (coupled)
Berthing Analysis
Spread Mooring System for Station Keeping
Mooring Pattern Design
Catenary shape derivation
Clash check with sub-sea structure
Placement of DP buoys
Line damage or transient analysis
Relocation or safe parking zone
Single Point Mooring System
Vessel shape optimization as per Motion Analysis
Single point and Tandem mooring system design
Line fatigue analysis
Mooring analysis for Pipe/Cable laying operation
Mooring analysis of layup vessel
