[Report of] ISSC Committee: Loads
[Report of] ISSC Committee: Loads
The content of this committee’s report is dictated by its mandate, as well as the expertise of its membership. Its structure follows along similar lines to that adopted in ISSC 2003. Wave-induced loads on ships are dealt within two different sections, namely 2 and 4. The former focuses on 2D and 3D methods, examining current practice in linear and progress in nonlinear methods together with applications of so called CFD (Computational Fluid Dynamics) methods. In addition full-scale and flexible model test measurements are reviewed. The latter focusses on impact related loads, namely slamming, sloshing and green water. The section on offshore structures focusses on multi-body interactions and floating-mooring system interactions, with particular reference to instabilities and the clashing event for the latter. In addition current status on vortex induced vibrations is reviewed. Developments for VLFS are not included in this report, as these are within the remit of Specialist Task Committee VI.2. As with previous reports, current state of progress in short- and long-term predictions is examined and their interaction with the development of rules discussed. Uncertainties in experimental and full-scale measurements and computational methods are discussed with reference to the verification and validation process. This is an extremely important issue that is beginning to gain ground where dynamic loads are concerned, but has yet to reach the level attained in steady state computations and measurements.
A number of new subject for this committee areas have also been incorporated. There is a comprehensive analysis of ice loads and a separate section devoted to large amplitude roll, due to the significance of these issues. Loads induced by rogue or freak waves make for another area of concern for designers of ships and offshore structures. Consequently the emerging small body of work on loads induced by such waves has been reviewed. Comprehensive review of fatigue loading was presented in the last ISSC by the Special Task Committee VI.1, which no longer exists. The latest developments in this area are discussed in this report, as the committee’s expertise could stretch this far.

Abstract

The content of this committee’s report is dictated by its mandate, as well as the expertise of its membership. Its structure follows along similar lines to that adopted in ISSC 2003. Wave-induced loads on ships are dealt within two different sections, namely 2 and 4. The former focuses on 2D and 3D methods, examining current practice in linear and progress in nonlinear methods together with applications of so called CFD (Computational Fluid Dynamics) methods. In addition full-scale and flexible model test measurements are reviewed. The latter focusses on impact related loads, namely slamming, sloshing and green water. The section on offshore structures focusses on multi-body interactions and floating-mooring system interactions, with particular reference to instabilities and the clashing event for the latter. In addition current status on vortex induced vibrations is reviewed. Developments for VLFS are not included in this report, as these are within the remit of Specialist Task Committee VI.2. As with previous reports, current state of progress in short- and long-term predictions is examined and their interaction with the development of rules discussed. Uncertainties in experimental and full-scale measurements and computational methods are discussed with reference to the verification and validation process. This is an extremely important issue that is beginning to gain ground where dynamic loads are concerned, but has yet to reach the level attained in steady state computations and measurements.
A number of new subject for this committee areas have also been incorporated. There is a comprehensive analysis of ice loads and a separate section devoted to large amplitude roll, due to the significance of these issues. Loads induced by rogue or freak waves make for another area of concern for designers of ships and offshore structures. Consequently the emerging small body of work on loads induced by such waves has been reviewed. Comprehensive review of fatigue loading was presented in the last ISSC by the Special Task Committee VI.1, which no longer exists. The latest developments in this area are discussed in this report, as the committee’s expertise could stretch this far.
