The six components of liner service costs listed in Table 10.3 are the service schedule; ship costs; port charges (including cargo working); container operations; container costs; and administration. This is not a classification which appears in the accounts of any liner company, but it is a useful way of grouping cost variables to discuss their role in the business.The logical starting point for liner cost analysis is the service schedule (Table 10.3, section 1), since this sets the inflexible framework of transport capacity per annum around which costs are incurred.
