... in the industry. In this paper, by means of a model experiment and a numerical calculation, we focused on constraining forces at the contact point (fenders) between the bow of the SWATH CTV and the offshore wind tower to determine the cause of the stick/slip characteristics. Then, we clarified the constraining...

... that measure the ship movements, mooring forces, and fender forces of a 50000 DWT container ship under various sea states were conducted, and the critical wave conditions and the corresponding downtimes were analyzed. An undistorted model at scale 1:58 was built to replicate the piers, breakwater...

.... It shows that HMPE ropes should be preferred for the bunker vessel.Additionally, the mooring design scheme of mooring line in combination with fender is capable of meeting the limited operation environmental conditions specified by OCIMF. These findings are helpful for the bunkering mooring system design...

... during the lift-off operations under various irregular waves. The dominant operational criterion is the re-hit force between the spool and the deck of the barge after the spool being lifted. To seek for a potential improvement of the sea states, different fender supports have been modeled. It is shown...

... a pre-installed fixed structure using a transportation barge together with a system of mooring lines, fenders, guides, bumpers, ballast system, and mating equipment. The pre-installed fixed structure may be a steel piled jacket, a group of freestanding piles, or a gravity-based structure. This technique...

... system is composed with a number of mooring ropes and fenders, which might trigger unexpected motions. In this study, eigenvalue analysis was conducted, which gives the resonant frequencies and modes of vessels induced by the ship-to-ship mooring system. These eigenvalues were drawn in the model test...

... to guide the vessel stern for initial smooth docking into the jacket slot. Four sets of sway fenders are mounted on the jacket legs inside the eight-legged jacket slot to absorb impact between jacket legs and vessel sideshells and also to ensure mating cones within capture radius of leg mating units (LMU...

For topsides mating analysis, DSUs, DSF Support Points, LMUs, steel-to-steel contacts at LMU points, sway fenders, mooring lines and many...

.... During the test, the vessel motion, line tensions, and fender forces were measured under various irregular wave headings i.e. head sea and beam sea. The relation between the vessel surge motion and line tension was investigated under head sea waves. Wave period effects were also studied in the condition...

... ABSTRACT Currently, the life time of rubber marine fender (hereafter "fender") has been evaluated by the external damage but many of large size fenders are not visually deteriorated even after over 30 years of use. But, there is a concern that material and performance maybe changed even though...
