“…Although CFD has been extensively used for modern yacht and ship designs, its application to traditional fishing boats is less common. Traditional fishing boats often rely on empirical knowledge and inherited design practices, which may not always consider the hydrodynamic interactions between the hull, sail, and surrounding fluids [18]. Moreover, the integration of sails as a hybrid propulsion system with fishing boat engines to enhance fuel efficiency and reduce emissions is a relatively novel concept that has not been widely studied [11].…”

The potential of using sails and Computational Fluid Dynamics (CFD) to improve the sustainability of traditional fishing boats in the Maluku region. This study highlights the importance of cost-effectiveness and environmental sustainability in the fishing industry. This study shows that Computational Fluid Dynamics (CFD) is effective in simulating the thrust force generated by sails. Sails were used to generate thrust forces on conventional fishing vessels by implementing CFD methodology with three different models. Various sail shapes were incorporated into the modelling process to assess their impact on the thrust force. Subsequently, a comprehensive analysis was conducted to evaluate the sail thrust force under typical operating conditions, focusing specifically on the average speed of the vessel at 15 knots in the waters surrounding the Maluku Islands. The results reveal that sail model 1 has the highest thrust force, amounting to 240.2 N. Sail models 3 and 2 generate thrust forces of 238.9 N and 227.9 N, respectively. The fluid flow conditions around sail model 1 and screen model 2 provide valuable insights into how the sail interacts with the fluid environment to produce thrust. By understanding and optimizing these fluid dynamics, designers and engineers can enhance the performance of sail models and improve their efficiency in harnessing wind power for propulsion. This study highlights the importance of ship science and technology in the design of appropriate propulsion systems for traditional fishing vessels.

“…The 30 GT fishing vessels produced by fishing communities along Indonesian waters generally use a diesel engine as the driving force for the ship, the determination of which is based solely on the experience of the artisans and the availability of machinery components on the market. This factor makes it impossible to achieve the vessel speed [5][6][7], The low propulsion efficiency of fishing vessels, in addition to impacting the high use of fuel oil consumption [8], also affects the vibration and noise generated. Furthermore, this impact of vibration and noise can cause damage to structures, machinery equipment, and crew discomfort [9], Researchers have made several efforts to optimize the propulsion efficiency of fishing vessels, including redesigning the propeller [10] and rearranging the propeller placement [11 13], In their research, Muhammad et al [14] stated that the order of asymmetric propellers, which is widely applied to some fishing vessels, affects 1.…”

Reducing fuel consumption and carbon emissions in the development of ship propulsion systems following the required Energy Efficiency Design Index (EEDI) has become a concern for the fishing industry as determined by the International Maritime Organization (IMO). This study analyzes the suitability of using a 30 GT fishing vessel propeller and propulsion engine for optimum efficiency. The analysis focuses on developing a propulsion system selection model, studying the characteristics of the ship's resistance, loading propellers, and selecting the appropriate engine. The propeller-engine matching procedure predicts the propeller and engine suitability. Furthermore, the Analytic Hierarchy Process (AHP) method determines the suitability level for the propeller and diesel engine. The results showed the highest level of suitability for the Yanmar 6CH-HHTEC engine versus the A.30X34 type propeller with 31.7%. Then the Deutz BF06M1013MC engine versus the B.30X28 propeller type, the Yuchai YC6A170C engine versus the B30X28 propeller type, and the Volvo D7ATA engine versus the B30X28 propeller type with percentages of 26.6%, 26.4%, and 15.3%, respectively. The high level of SP2 selection is due to the propulsion system having minimal noise levels, dimensions, and engine weight but having maximum power.

“…Dispersants increase the thermal conductivity of oil and slow down the process of paraffin crystallization. Due to the increase in duration for paraffin crystals being in a dispersed suspended state, the possibility of removal thereof from the well equipment at the wellhead increases (Windyandari et al, 2018;).…”

The problem of the formation of asphalt-resin-paraffin deposits (ARPD) in oil fields within the “well – bottom-hole formation zone” system is still relevant. To prevent the formation of ARPD in the “bottom-hole formation zone – well” system, the ARPD inhibitors must have high adsorption and low desorption properties concerning the rock. The composition of inhibitors often includes surfactants. Nonionic surfactants, namely, polyesters, are widely used to prevent the formation of ARPD. However, currently, little is known about inhibitors with a combined effect, for example, possessing depressor-dispersing properties for ARPD. This work aimed to develop a combined inhibitor possessing not only depressor-dispersing properties but also having good adsorption and desorption properties to the rock to prevent the formation of ARPD. The paper presents the research results on the development of an ARPD inhibitor, as well as the effects of determination of its depressor dispersing, inhibiting, and corrosive properties; the temperature of oil saturation with paraffin is determined as well. The studies of the ARPD inhibitor adsorption were carried out by the static and dynamic methods. In contrast, the process of the inhibitor desorption was studied by oil filtering through a saturated sample of the rock using a bulk model and core material. The impact of the fluid flow rate on the inhibitor desorption rate was studied. The technological parameters of the ARPD inhibitor solution injection into the bottom-hole formation zone of production wells were calculated. The developed composition has high inhibiting properties concerning the ARPD, depressor dispersing properties, low corrosive activity for a metal surface, and is capable of lowering the temperature of oil saturation with paraffin.
