Single Point Mooring (SPM) is a type of offshore facility that is used for the loading and unloading of oil and gas tankers in the sea. In Iran, it is briefly called “floating buoy”. The present study discussed floating type, fixed to the seabed with mooring chain. The mooring chain of SPM, which is considered one of the important parameters of its design, will be evaluated with reg...

Abstract: In this study, a deterministic approach for the dynamic analysis of a multi-component mooring line was formulated. The floater motion responses were considered as the mooring line upper boundary conditions while the anchored point was considered as pinned. Lumped parameter approach was adopted for the mooring line modelling. The forces considered were the submerged weights of mooring/...

In this paper, the mooring dynamic loads and the motion responses of a large container ship in irregular waves with steady wind and current is investigated based on the commercial software AQWA. Comparisons between the time-history motion responses of a large container ship and the change of the mooring line tension in three different cases, non-mooring case, V-type mooring case and I-type moor...

The dynamic responses of mooring line serve important functions in the station keeping of a floating wind turbine (FWT). Mooring line damping significantly influences the global motions of a FWT. This study investigates the estimation of mooring line damping on the basis of the National Renewable Energy Laboratory 5 MW offshore wind turbine model that is mounted on the ITI Energy barge. A numer...

In this paper, a new side-by-side mooring bay designed by Keppel Offshore & Marine Technology Centre is investigated, and its global performance and dynamic stability are compared against those of the traditional SPM-mooring system. The multi-body systems include SPM buoy with a turntable and mooring system, a VLCC FPSO, oil tanker, and the hawsers/fenders and yokes between them. A time-domain ...

Like all other floating structures, wave energy converters (WECs) need to be kept in position by station-keeping systems in order to realize its functionality and ensure its safety. A compliant mooring system is normally applied and survivability is the main concern for mooring system design. However, WECs based on relative motions impose special requirements on their mooring systems to ensure ...

In this study, dynamic behavior of a mooring line in a floating system is analyzed by probability approaches. In dynamics, most researches have shown the system model and environments by mathematical expression. We called this process as the forward dynamics. However, there is a limit to define the exact environments because of uncertainty. To consider uncertainty, we introduce the redundancy i...

Cyprus’ offshore aquaculture industry has promising prospects taking into account that Cyprus is an island. Its production trend is increasing overtaking bigger countries such Greece and Italy. However, current mooring systems seem to be under-performing acting as obstacles for its future development. Furthermore, shallow coastal waters scarcity due to competing industries dictates future devel...
