Concerning the safety of towing operations, a condition on tug-towed ship motions
interaction during turning is necessary to be studied. This paper presents an analysis
of the turning ability of a towing system consisting of a tug and a barge. The influence
of several parameters is examined on the turning performance of the towing system.
To obtain the objectives by looking into achivable precised outcomes, whilst a
hydrodynamic description that is underlying the rationale behind the explained results,
a Computational Fluid Dynamic (CFD) is proposed for a better prediction of their
turning ability including capturing the increasing of tow point, where effects of towline
length and turning diameter are discussed. This analysis revealed the longer towline,
larger tug and tow point nearer to the bow of the barge increase the turning diameter.
Tow point on the tug closer to its centre of gravity decreases the turning diameter
significantly thus will shortened the towline length hence increase the stability of the
ship towing operations.
