The essence of RoRos is that everything is wheeled in and off.Thanks - wondering if there was "space round the edges" for spares given the horror stories about replacement windscreen times.
Spare parts etc are normally shipped via container. This is usually a cheap and very fast method however at the moment it's neither.
There is still a shortage of containers in China although the cost of new containers is showing a reducing trend.
Shipping companies are being accussed of profiteering and Governments are under pressure to try and force a reduction in the currently high shipping costs. This will prove to be a difficult nut to crack unless there is clear evidence of anti-competitive practices.
