At Tadek Ocean Engineering, we carry out Quayside Mooring Analysis for Cable-Laying Vessels (CLVs) to ensure safe vessel positioning during offshore cable repair operations. These assessments are essential for maintaining operability and structural integrity, especially when operating from ports or quaysides with variable environmental loading.
Our methodology is aligned with OCIMF MEG4 guidelines and includes both Intact and Damaged Line Cases, ensuring robust, contingency-ready mooring plans.
Scope of Analysis
Our deliverables include:
- Hydrodynamic Modelling to simulate vessel responses to waves, wind, and currents.
- Environmental Load Assessments, using site-specific metocean data.
- Mooring Analysis:
- Line tensions and bollard utilisation
- Vessel excursion and limiting wind conditions
- Technical Reporting:
- Clear recommendations for safe operating windows
- Mooring layout diagrams for operational use
We provide visual plots and polar diagrams to present line loadings and directional forces clearly to engineering and operations teams.
Case Study: Mooring Analysis at Nigg
We recently completed a mooring study for two cargo vessels berthed at Nigg. The project involved two bollard configurations (SWL 12t and 48t) under multiple environmental conditions.
Key highlights:
- Hydrodynamic models were built for both vessels.
- Wind and current coefficients were calculated.
- Two mooring configurations were proposed.
- Line utilisation was evaluated for both Intact Case (IC) and Damaged Case (DC).
Outcome:
The operability was governed by vessel bollard limitations, and recommendations were tailored to minimise overload risk across all lines.
Terminal & Quayside & Mooring Case Studies – All vessel types
Our expertise in offshore and quayside mooring ensures that vessel operations can proceed safely and efficiently backed by data, modelling and operational clarity.
