Bamboo resources in Indonesia is abundant and have big potential to be development. Bamboo has been used as raw material for industry or construction. However bamboo also has some limitations when used for construction material, due to its diameter. Oriented strand board (OSB) is one of the alternative to increase the efficient utilization of bamboo for construction material. The objective of this study was to evaluate the properties of OSB on various shelling ratio and to evaluate the relation of mechanical properties of OSB via destructive and non-destructive testing. Strands were steamed at 126 oC for 1 h under 0.14 MPa. Three-layer OSB with core layer perpendicular to the surface and back layers were formed and binded with 8% of phenol formaldehyde (PF) resin with the addition of 1% of wax. Shelling ratio investigation of OSB was carried out by several types of strand with the ratio of face and core layer were 50:50, 55:45, 60:40, 65:35, 70:30, and 75:25 based on the strand oven dry weight on percent. From the result show that physical and mechanical properties of OSB that treated by steam was meet the requirement of CSA 0437 (Grade O-2) and EN 300 (Grade 2) standard. Non-destructive test using simple regression analyze was performed to analyze the statistic modulus elasticity (MOEs), modulus of rupture (MOR) of several shelling ratio. At shelling ratio 70:30 and 75:25 with parallel direction have higher mechanical properties as compared to perpendicular direction. OSB treated by steam has lower emission as compared to untreated OSB.

An offshore installation is built or installed for the purposes of exploration and exploitation in any part of the sea. The offshore installations that are presently in existence reflect great scientific progress in the field of marine resources. However, they become a source of concern when they are no longer in use. Due to the potential to disrupt activities conducted around their location, they interfere with navigational safety. Therefore, it is important to remove such installations. Their removal should be based on the provisions of the IMO Guidelines and Standards. Indonesia is a coastal State and should adhere to the above mentioned guidelines and standard in designing policies and regulations.
