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.
