Abstract

Perangkat Automatic Identification System (AIS) adalah salah satu perangkat yang wajib dipasang pada kapal berukuran lebih besar dari 300 GT. Penggunaan perangkat AIS dimaksudkan untuk meningkatkan keamanan dan keselamatan di laut (SOLAS, Safety of Life at Sea). Penelitian ini merupakan kelanjutan dari penelitian yang telah dilakukan sebelumnya terkait dengan pemanfaatan AIS untuk inspection score pengawasan kapal dan monitoring pipa bawah laut. Hasil-hasil penelitian tersebut mendasari pembangunan konsep dasar sebuah prototype software real time monitoring berbasis AIS. Prototype yang dikembangkan saat ini adalah monitoring real time untuk anjungan lepas pantai dan pipa bawah laut, skor inspeksi kapal, dan ship tracking. mengolah data AIS sedemikian rupa dan membandingkan dengan lokasi fasilitas anjungan lepas pantai dan pipa bawah laut. Monitoring anjungan lepas pantai dan pipa bawah laut memungkinan dalam kondisi bahaya, sistem akan mengirimkan peringatan dini melalui notifikasi telepon seluler, surat elektronik dan media komunikasi lain. Sistem inspeksi kapal bermaksud untuk memonitor lalu lintas kapal dalam daerah perairan tertentu. Oleh otoritas pelabuhan, fitur ini dapat digunakan untuk memudahkan dalam menentukan prioritas kapal-kapal yang akan dilakukan inspeksi. Fitur lainnya yang dikembangkan adalah sistem data historis, yaitu penampilan kembali vessel track dalam kurun waktu, batas daerah perairan atau untuk memperlihatkan jalur/track beberapa kapal tertentu. Pengembangan prototype software ini diharapkan dapat berkontribusi dalam meningkatkan keamanan dan keselamatan operasional kapal dan fasilitas lepas pantai/bawah laut serta meningkatkan efisiensi dalam melakukan monitoring terhadap lalu lintas laut.

Abstract

This paper examines the risk to subsea gas pipeline during hot-tapping installation process. Hot tapping is one method to connect new pipeline to existing pipeline while they remain in service. In this study it is considered that hot tapping is installed using crane barge. To assure the crane barge in steady position, the crane barge is moored by means of mooring chain at several locations. These mooring activities and hot tapping installation possess potential risk to existing subsea facilities. Hence, in general there are two objectives in this study such as: determining the safe distance between mooring chain for and the existing facilities, and performing risk level due to external load that may occurs during installation. The risk level is determined by analyzing frequency and its consequence then will be mapped into risk matrix according to DNV-RP-F107. From mooring distance analysis, the result can be used as a reference for positioning the mooring point of crane barge. Based on the result of risk assessment to facilities, risks due to external load such as dropped anchor, dragged anchor, ship sinking and dropped object are in the as low as reasonably practicable (ALARP) region which mean, in the practical life risks are acceptable as long as the frequency is maintained in the lowest rank.

Abstract

Choosing a shipyard that does not meet the requirements can affect ship building process. Incompatibility of construction process can cause delays in completion time or delivery of ship to shipowner. The resulting delays can affect reputation of shipowner because they cannot fulfill their cargo delivery services, where cargo contract is generally carried out before ship is handed over from shipyard to shipowner. Delays will also affect insurance providers, both ship and cargo insurance. A stricter evaluation from insurance company could result in an increase in premiums charged due to risks that will be faced in the future. The aim is to determine priority of shipyards that will be appointed for ship construction in Batam area. Because shipyard selection does not only involve quantitative but also qualitative variables, Multi-Criteria Decision Making (MCDM) method was used in this research. Method used in selection is a combination of Analytical Hierarchy Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). AHP is used to determine weight of the criteria and sub-criteria used in selection, while TOPSIS is used to determine shipyard selection priorities based on weight of criteria and sub-criteria that have been generated from AHP process. Respondents in this study were representatives of three ship owners, consisting of two technical managers and one deputy general manager. Based on the results of the analysis of six shipyards in Batam area, a priority order of shipyards recommended for ship construction by company was obtained. Sensitivity analysis also shows that the results produced in shipyard selection are quite robust.
