Design of an Optimum Battery Electric Fishing Vessel for Natuna Sea

Abstract

⎯ Natuna Sea is one of the places in Indonesia, which has a high potency of fish up to one million ton per year. Fisherman in Indonesia relies too much on the fossil fuel, which has limited resources. The author wants to redesign the fishing vessel into the battery electric fishing vessel that can be recharge to reduce the use of fossil fuel and also to increasing the revenue of the fisherman. To minimize the capacity of the battery, the fishing activities concept is also change into centralized fishing activities which the activities is centralized in an open sea and has the offshore building as the fishing base that has power station to recharge the batteries and cold storage to collect all the fishes. As the object to redesign, it is used 10 GT purse seine fishing vessel. As the results of the calculation, it gets the total battery capacity 6000 Ah for operation 11 hours (4 hours travel time, 6.5 hours fishing activities, and 0.5 hours break). Based on the technical and economic analysis, it can be concluded that the battery electric fishing vessel has a better revenue and fewer expenses than the diesel-powered fishing vessel. Keywords⎯ batteries, electric propulsion systems, fishing vessels, Natuna Sea.

Systematic Review of Solar and Wind Power Plants for 14-Meter Fishing Boats

“…In general, the design of a hybrid boat focuses on three key areas: (1) sails that create the most thrust; (2) a system that generates electricity from solar cells to power the ship; and (3) the shape of the ship's hull for minimal resistance and excellent mobility [15]. Another study mentions that the ideal battery for 10 GT electric fishing boats in the Natuna Sea is 6,000 Ah, with a range of around 14 NM, a speed of approximately 7 knots, and fishing activities of approximately 6.5 hours [16].…”

“…Battery capacity calculations are carried out to determine the amount of battery provided to cover the electrical load on board. For emergencies, 10 -15% of the total capacity can be added [16].…”

“…According to the total load calculated above, the minimum capacity of the battery is about 24,433 Ah, which is calculated by dividing the battery voltage by the kWh load [16]. Moreover, according to equation ( 2) and the specifications in Table 4, the number of batteries that must be provided is about 240 units with a total weight of approx.…”

Short-circuit current analysis of DC distribution system in a ship with non-electric propulsion

“…Possible methods to decrease ship energy consumption in the electrical power system including the engagement of renewable energy resources [4]- [7], optimal power management system [8], [9], and efficient distribution systems [10], [11]. In Indonesia, most of vessels are still using diesel engines in their propulsion system and conventional radial AC distribution systems in their electrical grid [12]. Therefore, one of the Int J Appl Power Eng ISSN: 2252-8792  Short-circuit current analysis of DC distribution system in a ship with … (Adi Kurniawan) 363 most reasonable choices as the first step to decrease energy consumption for ships operated in Indonesia is to improve the efficiency of power distribution system.…”
