Blast hazard load on offshore and marine operation resulting very catastrophic failure. Installation of protection devices needs to be applied. There are active and passive protection available. This paper investigates the use of corrugated plate as a passive protection to resist blast loads based on ASCE (American Society of Civil Engineers) - Design of Blast Resistant Building in Petrochemical Facilities. This paper aims to investigate the response in terms of stress, deformation and energy dissipation of corrugated plate with accounting the effect of boundary condition.The horizontally installed corrugated plate is modeled using well known FEA Software, ANSYS. Numerical simulation is validated using meshing sensitivity study. The plate is then
loaded by light, medium, and heavy explosions, represented by uniform pressure. Numerical simulation of non-linear structural analysis is performed. Based on the analysis result, it is concluded that the pinned and fixed boundary condition corrugated plate successfully resists the all the blast load variations, but the pinned support gives average better responses..

Indonesia is the world's largest archipelagic country in the world, demand for marine transportation is very important. Marine transport being very strategic because it plays a role in connecting one island to another island and marine transport is a tool for economic activity. Global industrialisation causes traditional shipyard less competitive, causing reduction in the number of traditional ships, which are urgently needed to support economic activity. Proper production management planning at the shipyard is expected to help improve the quality of traditional shipbuilding for competitive. This paper discusses current issues of traditional
shipyards in Kepulauan Riau-Indonesia and implementation of IDEF models as tool for solving the problem by taking the following factors into account: concept design, perform preliminary design, contract design, detail design and building of ships.

This study aims to analyze global wave climates of present and future time by using the WAM model. The analysis is performed based on wind climate data from the JMA/MRI-AGCM3.2 climate change projection. We analyze two 6-hourly wind data sets, covering two periods: the present climate ranging from 1979-2003 and future climate extending from 2075-2099. These wind data are used to implement the WAM model for producing the outputs of wave characteristics. Subsequently, the outputs from each period were used to study global wave climate in the future. The analysis showed that the wave climate is strongly dependent on the geographical position of regions from mid to high latitude and low latitude. This includes regions where the climate induced changes for present to future climate. The largest increases of significant wave height which reached approximately 5% occur in the southern parts of the Indian, Pacific and Atlantic Oceans and in the Antarctic Ocean. The decreases in the same magnitude around 5% occur especially in the North Atlantic Ocean.
