“…In addition to studies assessing the abundance of the energy resource, some work has focussed on MRE technologies developed by groups of researchers in Indonesia [15][16][17][18][19][20]. An initial experiment to investigate the effect of fixed-pitch and passive variable pitch to vertical-axis turbine performance was carried out in 2011.…”

“…A wave energy converter (WEC) using a pendulum system was also invented in 2010, and an experimental approach was performed to analyse the novel geometry of a pontoon in maximising the amplitude of pendulum oscillation [19]. This study was then continued to investigate the mooring configuration by determining the heave, pitch and roll response of pontoon [20].…”

Marine renewable energy holds strategic potential in Indonesia, not only to meet the target of renewable energy share in the national energy mix but also to provide equal access to clean energy throughout the archipelago. Marine energy in Indonesia is still in the early phase of development, which mainly focusses on resources assessment and power generation through technology prototype testing. Based on a review of available literature, it is found that specific research on the effects of biofouling on material durability of marine energy infrastructure in Indonesia has yet to be addressed. In this study, a matrix that identifies and predicts key fouling organisms and their possible risks on marine renewable energy infrastructure in tropical waters of Indonesia is developed by analysing previous findings in temperate and subtropical waters. Based on the matrix developed, calcareous polychaetes (Serpulidae), barnacles (Amphibalanus spp.), and bivalves (Perna viridis) are among possible key fouling organisms that might pose risks to marine energy infrastructure in Indonesia, such as by adding weight and drag and causing corrosion. Further studies and detailed and statistically robust analysis of the biofouling and its impacts are needed to support the development of the technological performance of marine renewable energy in Indonesia.

The design of a marine current turbine generator specifically in deep water with unequal seabed which requires the designer to develop a floating platform for the turbine. It creates a massive challenge in improving the mechanical system, such as the turbine arm. In order to make the monitoring and maintenance accessible, the generator must be placed on the platform’s deck. A long shaft is required to make the connection between the generator and turbine. The problems occur due to the vibration generated by the vortex around the shaft or the turbine arm. This paper aim is to investigate the vortex effect on the turbine arm and propose an advanced design to reduce its impact. The computational fluid dynamic method is approached to analyse the vortex generated by the turbine arm. The analysis compared the conventional cylindrical and the foil-shaped turbine arm. Moreover, the investigation includes force along the X-axis and Y-axis, flow, drag, lift coefficient, also fatigue lift near the turbine arm. The numerical output illustrates that the foil shaped on the turbine arm provided limited vortex and improved the performance compared to the conventional cylindrical turbine arm.

“…Free-floating barge with an angle 45° at portside and starboard hull could capture ocean wave energy to convert high-value moment or kinetic energy compared with other motions of models like a cylinder or box hull [12]. Barge movement that often occurs in free-floating is a roll, pitch, and heave [13]. This paper presented the position of mooring bitts influence motions of a barge.…”

Potential wave energy in Indonesia between 5 kW m–1 to 20 kW m–1 depending on-site location coastline. This research in ocean energy of Wave Energy Conversion (WEC) is wave activated body using the floating or motion hull due to kinetic and momentum energy from an ocean wave. The pendulum movement cause by a floating hull to drive the electric generator. The shape of the hull, displacement, and position point of the mooring line greatly influences the movement of the hull. This paper discusses how to computational fluid dynamics (CFD) simulation can solve and determine the best mooring line position in the hull. Moreover, the shape of the hull at under waterline or drought has slope angle 45°, length overall 3 m, breadth 1.5 m, depth 2 m, and draft 0.65 m. One of the boundary conditions in the domain CFD, the direction of a wave from inlet boundary to starboard or port side using regular wave. The position both of mooring bitts are at forwarding perpendicular and after perpendicular. Three-position of mooring bitts that have simulated CFD: under the waterline, (ii) at the waterline, and (iii) up waterline. The result of simulation that the best position of mooring bitts is at the waterline.
