   Abstract:  Analysis of barge models to capture the energy from ocean wave Irfan Syarif Arief Email: irfansya@its.ac.id, handphone : +62816534894, fax number:+62315994754 Department of Marine Engineering , Institut Teknologi Sepuluh Nopember (ITS) Surabaya Zamrisyaf Sy Email : zamrisyaf@gmail.com , handphone:+6281973552165, fax number :+62217991762 State-owned General Electricity Company of Indonesia/ PT. PLN (Persero) One of energy renewable used of ocean wave energy. A variety of technologies have been proposed to capture the energy from waves. Wave technologies have been designed to be installed in near shore, offshore, and far offshore locations. The paper deals with how to design hull of barge to capture ocean wave energy. The both of motions of barge are rotations and translations appear due to impact directly from surface waves or from pressure fluctuations below the surface and which ocean wave energy convert to kinetic energy. On the deck of barge to be installed horizontal or vertical of pendulum be able to move one way rotation and to be connected with an electric generators is device that converts mechanical energy to electrical energy. The objective of research to find good models barge that have given high value moment due to impact of variety of characteristic ocean wave. The methodology to solve problem used to computational fluid dynamics (CFD) and there are three shape models of barge have been done simulation. Keywords: Wave Energy, Ocean Wave, CFD, Horizontal of pendulum, Vertical of Pendulum Objectives: The objectives of research to find good performance models of barge which to capture ocean wave energy and give impact high value moment (My). Result:   There are three models of barge have been done simulation. Every model of barge which surface fore perpendicular of hull has three shape models round , with angle  and box . The result of simulations that have been given good performance is a barge which shape model using with angle 45 o . It model can be captured ocean wave energy to convert high value moment or kinetic energy compared with another motion of models. Conclusions:   Ocean wave every location always have different characteristic, so we must calculation over again to reach good models of barge. Henceforward the result of research the paper can be representative to choice of good barge and give method how to design hull of barge can be capture ocean wave energy very good.
