Abstract/Description
-
A folding span deployed between two ships is proposed for dry cargo transfer during replenishment operations at sea. This structure is modeled as a one-dimensional truss-work, composed of spatially periodic units. The governing equation is formulated for a single periodic unit by a finite element method. A transfer matrix method is then used to connect it to its neighboring units. The dynamic response of the structure is finally obtained by a wave propagation approach. For application to...
Show moreA folding span deployed between two ships is proposed for dry cargo transfer during replenishment operations at sea. This structure is modeled as a one-dimensional truss-work, composed of spatially periodic units. The governing equation is formulated for a single periodic unit by a finite element method. A transfer matrix method is then used to connect it to its neighboring units. The dynamic response of the structure is finally obtained by a wave propagation approach. For application to underway replenishment (UNREP), this analysis is extended to the case of a travelling load and to the case of moving boundaries, which accounts for the relative motion of the supplying and receiving ships. Moreover, a parametric study is conducted for future design purpose.

Abstract/Description
-
At sea cargo transfer has historically been a logistical challenge for both the military and the offshore industry. Even in moderate seas, three to five foot wave heights, extreme pendulations of cargo and large relative motions between vessels can occur that halts cargo transfer activities. This work develops a six-degree-of-freedom rigid crane dynamics model that is used to investigate the feasibility of crane target tracking which could extend and enhance offshore crane operations.

Show moreAt sea cargo transfer has historically been a logistical challenge for both the military and the offshore industry. Even in moderate seas, three to five foot wave heights, extreme pendulations of cargo and large relative motions between vessels can occur that halts cargo transfer activities. This work develops a six-degree-of-freedom rigid crane dynamics model that is used to investigate the feasibility of crane target tracking which could extend and enhance offshore crane operations. A double girder crane system is developed that easily adapts to different configurations and efficiently supports long reach heavy lift applications. Target tracking is feasible in sea states up to 5 when using the double girder crane. When compared to a present crane system, the target tracking crane requires, on average, only 3.65% more absolute total system power and 13.4% less continuous power, indicating that the proposed system should be realizable.
