Abstract

In recent years, the number of shipyards in Indonesia has increased significantly to anticipate the increasing demand and the government policy regarding the Cabotage Principles and Masterplan for Acceleration and Expansion of Indonesia’s Economic Development (MAEIED), and three Archipelagic Sea-Lanes (ASL’s) in Indonesia. However, shipbuilding and ship repair works have been centered in the western part of Indonesia. Therefore, this study aims to develop a potential strategy of shipyards in the eastern part of Indonesia to compete in the current market situation. The Analytical Hierarchy Process (AHP) method was used to model the strategy hierarchy and analyze the weight of sub-criteria as the internal and external factors of the shipyard competitiveness. Then, the Blue Ocean Strategy method was used to analyze the competitiveness strategy. To improve competitiveness, the shipbuilding industries in the eastern part of Indonesia have to focus intensively on reforming and upgrading several internal environment factors such as coordination and response, business network, high skill manpower, and complex ship types building ability. Besides, the shipyards also have to focus on external environmental factors, particularly on five factors that have a high influence on improving competitiveness, namely shipping company partners, networks and partnership with suppliers, government policies, human resource development, and cluster formation of shipyards.

Abstract

The impact pressure induced by slamming can imply physical damage on a ship. The high probability of the slamming impact is on the bow part in the actual sea state. In this present study, the slamming induced pressure on the bow flare of a ship have been investigated through the experiment. The experiment was schemed by the dropping test based on free-falling body in the wave tank, wherein the bow of the ship model was inclined in several impact angles 0° to 30° to the free-water surface. To measure slamming impact pressure acting on the bow flare, the piezoelectric sensors S1, S2, S3, S4 were attached to the bow section and installed on a computer. As the obtained results, the impact pressure on bow flare occurred in a short time duration caused by slamming. The discrepancy of the peak impact pressure between ship model weight of 2.42 kg and 7.29 kg for the impact angle 0° is 70.36% S1, 69.52% S2, 68.97% S3, and 68.34% S4. For the relative impact angle of 30°, the discrepancy is 67.02% S1, 65.73% S2, 58.51% S3, and 48.21% S4. The tendency of the peak pressure coefficient at the sequenced impact points S1, S2, S3, S4 is similar for all impact angles 0°, 10°, 20°, and 30°. The peak pressure coefficient due to the full load condition is highest in the nearest bottom part, and the peak pressure coefficients due to the lightship condition highest in the nearest bottom part caused by the small impact angle.
