For some time now I have been observing large, 'slab - sided' car carrying vessels (like Wilhelmsen Lines m.v Trinidad coming into and out of Port.
Can anyone enlighten me as to the stability of these ships. I realise they must employ decent sized stabilisers (probably both tank and fin systems), but still a huge area for windage. What are they like in a big sea, and high wind?

I have served on huge car carriers for some time and at times we entered port with ""0"" stability.
New and better car carriers are required for safety.

Thanks for the response. Tell me, what sort of stabilising systems are employed in these ships?

There are no stabilising systems employed. Basic principle of residual stability is the underlying criterion.

Having a pair of stabilizers have really nothing to do with the concept of having adequate stability of a vessel. The so-called stabilizing system refers to means of reducing roll (and sometimes pitch as well). Having adequate stability means the vessel meets the minimum standards of transverse stability in INTACT undamaged condition. Usual standard is to assess this characteristic in three loading conditions: (a) Full Load; (b) Intermediate Condition; and (c)Minimum Operating Condition. When a vessel arrives at a destination port after an open ocean voyage, it has spent most of its consumables (fuel, water, etc.) resulting to rise in V.C.G. and hence reduction in GM(t). The minumum standards of required GM sre set forth in IMO regulations and also by the registry originating country, ADMINISTRATION, for safe operation of the vessel when it arrives in their port. It is the captain's obligation to follow the Trim and Stability Booklet guidelines and review at all times the vessel's GM(t) during the voyage and rectify if necessary by ballasting to meet the minimum GM(t) requirements. Taking account of the huge sail area due to beam wind and open-ocean operation are parts of the intact stability evaluation to meet this GM(t). The naval architect who prepared the Trim and Stability Booklet for the vessel takes these factors into his analysis. In these days, most of these ships are safe to operate if the captain is educated enough to understand these safety parameters, and most do. So, I would not worry too much of (intact) stability for vessels like you mentioned.

hello sir i am arunkumar i am doing my final year nautical technology. now i am doing a paper presentation on the topic "factros affecting the stability of a car carrier" can u help me by giving some idea sir,and i also heared there is no vertical bulk heads in a car carrier. will it also affect the stability of a ship
