“…Some apparent drawbacks are shown as water depth increases. 2 First, the cost of mooring line increases considerably with mooring length, besides, the excessive vertical load that comes from the chain weight decreases the vessel useful payload significantly. Furthermore, the mooring line may interfere with other engineering activities and bring the collision risk due to the large mooring radius.…”

In this article, a novel mooring system with side-mooring lines is proposed for a traditional shape semi-submersible platform with four columns. To obtain the dynamics of moored system, model tests were carried out at a wave basin, including free-decay model tests, white noise model tests and irregular model tests. The natural periods in heave, roll and pitch models were measured and compared with numerical results. The motion response amplitude operators under 90° and 135° waves were obtained from white noise model tests and then compared with numerical simulations. A 100-year sea state in South China Sea was simulated in the wave basin by the JONSWAP spectrum, and the 6-degree-of-freedom motion responses of semi-submersible and mooring tensions were recorded in beam and quartering seas. The effects of the side-mooring lines on the floating platform motion response, mooring tensions and mooring fatigue damage are evaluated by comparing the results with and without side-mooring lines installed.

“…Meanwhile, traditional catenary mooring system has demonstrated many drawbacks as water depth increases (Schmidt et al, 2006;Fonseca, 2009). Firstly, catenary chain or wire relies heavily on their own weight, which can provide restoring forces.…”

Analyzed are the merits and demerits of catenary mooring system and taut mooring system, which are commonly used nowadays. As falling somewhere between these two systems, a new mooring system integrating catenary with taut mooring is proposed. In order to expound and prove the advantages of this new system, the motion performance of a semi-submersible platform is simulated by employing full time domain coupled analysis method. A comparison of the result of new mooring system with that of taut mooring system shows that the movement of the platform using the new type mooring system is smaller than that using the taut mooring system, which ensures a better working condition. Furthermore, the new mooring system is also compatible with the characteristics of catenary mooring system, which eliminates the requirement of anti-uplift capacity of the anchors
