The highly nonlinear responses of compliant ocean structures characterized by a large-geometry restoring force and a coupled fluid-structure interaction excitation are of great interest to ocean engineers. Practical modeling, parameter identification, and incorporation of the inherent nonlinear dynamics in the design of these systems are essential and challenging. An experimental mooring system...

The aim of the presented research was: 1. to analyse the causes and effects of accidents that occurred on the Polish Ocean Lines ships in 1975-1980 at mooring manoeuvres. 2. Issuing certain prophylactic recommendations. The material of the research was information contained in the 95 accident record cards and in other post-accident documents such as rulings of the Marine Chamber, situational sk...

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...

Offshore oil and gas industry is blooming up towards the deep-water region of ocean deposit. Far off the continental shelf, the traditional jacket type fixed platform and bottom supported compliant platform are not suited to be economic offshore structure in deep water oil and gas exploration. Floating Spar platform is essentially most economic and efficient in these sea states. In the present ...

Mathematical analysis is an essential tool for the successful development and operation of wave energy converters (WECs). Mathematical models of moorings systems are therefore a requisite in the overall techno-economic design and operation of floating WECs. Mooring models (MMs) can be applied to a range of areas, such as WEC simulation, performance evaluation and optimisation, control design an...

Tacoma Narrows Constructors (TNC) is building a new suspension bridge in Tacoma, close to Seattle, Washington State, USA. The new bridge will be built just south of the existing bridge mounted on two caissons, referred to as East Caisson (Tacoma side) and West Caisson (Gig Harbor side). Each pier is about 80’ wide and 130’ long in plan. The mooring system for each caisson consists of two sets o...

The design of a mooring system for a floating structure is a significant challenge the choice of line structure and layout determine highly nonlinear hydrodynamic behaviors that, in turn, influence the dynamics of the whole system. The difficulty is particularly acute for Self-Reacting Point Absorber Wave Energy Converters (SRPA WEC) as these machines rely on their movements to extract useful p...
