APPLICATION OF LEAN CONCEPT TO SHIP SAFETY INSPECTION: A CASE STUDY AT PORT OF SURABAYA
Abstract: The Lean Concept is
a mindset widely used in various industries seeking for efficiency and
effectiveness through improvement of process flow and elimination of waste.
This research applies lean thinking to ship safety inspection at Port of
Surabaya to investigate the existing procedure and to identify the wastes and
non-value-add (NVA) activity. It used a combination of literature review,
examination on the data of 520 inspections that have been carried out to 201
ships in the last two years (2009 - 2011), investigation on related regulations
and guidelines, observation on the actual conduct of inspection, and interview
with 59 marine inspectors and ship officers. Analysis is conducted using Value
Stream Mapping (VSM). It is found that the existing procedure lacks significant
impact in terms of imposing a reduction in the total number of detected
deficiency between the earlier and subsequent inspections. Only 37% of the
ships experience a reduction, indicating that the performance of inspection is
currently at the level of 37 on a 100-point scale. It was mainly due to severe
violation of the regulations, which is demonstrated by the issuance of ship
certificate regardless of corrective action undertaken relating to the detected
deficiency.
