Abstract

This research aims to analyze main causes of waste and inefficiencies in crew boat management in order to determine practices for reducing the costs incurred from non-value added activities in the company of case studies, based on DMAIC process improvement of Lean Six Sigma. Way of improvement is to study about the waiting time of a vessel named “Hercules” as an example to find root causes of high fuel consumption while conducting waiting activity. This study aims to reduce fuel consumption by 20% when vessel is waiting mode. The study found that the activity of waiting for the next job has a share of 94% of all types of waiting activities. The major cause of high fuel consumption is from excessive use of main engines during waiting for the next job. The main problem is caused by a lack of fuel efficiency management awareness, attention of crew and boat controller; and there is no guideline for main engines usage while waiting for the next job. These gaps were closed by conducting training and building motivation for crew and boat controller and initiated documented procedures about fuel efficiency management during standby time. After the implementation of the control measures, the result was shown that fuel consumption rate during waiting activities was decreased form 106.83 liter per hour to 69.93 liter per hour, or decrease to 34%. Cost reduction is estimated at 1,583,432 baht per year.
