Stowage Tubes on Deck
The ship above carries its own stainless steel flexible hoses, which are very expensive, in stowage tubes on deck. This is a good idea because it assists against factors such as:-
Damage protection - The expensive stainless steel flexible hoses can be correctly stowed without any kinks and ship's staff cannot walk on the pipes, therefore reducing damage.
Weather protection - In cold climates there's less chance of the stainless flexible hoses from freezing, hence easier handling by ship's staff and quicker connections to shore facilities.
