1Impact of new technology on shipping operations- Workshop -
Danaos Auditorium, Piraeus, Greece May 13th
FLAGSHIP SP A2Key performance indicators for technical
operationMARINTEK - Brage Mo, senior research engineer
2 The use of key performance indicators (KPI) has become a recognised practice in measuring performance
The cargo owners and legislation bodies are increasingly focusing on documented proactive operation
Efficiency Environmentally Safety
Aggregated performance models of ships need to be made by transparent and consistent assessments of their technical condition
Background
3The TCI, the Technical Condition Index, is defined as follows: The Technical Condition Index, denoted TCI, is defined as the degree of
degradation relative to the design condition. The TCI can apply to equipment, a system, a whole ship or a fleet of ships. It
may take values between a minimum and a maximum value, where themaximum value describes the design condition [e.g. sea trial condition], TCI=100, and the minimum value describes the state of total degradation, TCI=0.
The state of total degradation is the condition so unsatisfactory that the equipment, system or ship is prevented from carrying out its primary function.
It is important to distinguish between the TCI and the KPI. The KPI are financial and non-financial metrics used to help an organization define and measure progress toward organizational goals [6]. In some instances the KPI and TCI can be the same thing, i.e. if one uses fuels cost as a KPI, this will be the same as the TCI fuel consumption.

Business process revision
Business processes might be different within similar businesses
Stakeholders know best how TCI results fit into their business processes
Consequently, stakeholders identify/ describe/ illustrate/ exemplify how the results fit into their organisations processes
