“…The measure is used across all ship types and is already relatively wide spread. In a survey by Rehmatulla et al (2017b) implementation of bulbous bows averaged between 32% and 47% in the respondents' fleet. A bulbous bow is not always appropriate and may in some cases increase resistance.…”

“…While implementation of the retrofit itself is not particularly complex, the opportunity costs might outweigh the potential fuel savings at dry-docks. Therefore, the measure is mostly applied on new builds (almost 80% according to survey by Rehmatulla et al, 2017b).…”

“…Several barriers constrain the diffusion of more energy efficient technologies in shipping, despite their potential (Rojon and Dieperink, 2014;Rehmatulla et al, 2017a). Many of these energy efficient technologies are applicable to ships operating under short-term time charter contracts which are prone to the split incentives and imperfect information barriers (Rehmatulla et al, 2017b).…”

The global trade share of international shipping is approximately 80% and it is therefore critical to the global economy. Carbon emissions from international shipping are expected to increase significantly in line with global trade trends. Several niche technologies for ship propulsion provide solutions to reduce shipping CO2 emissions. These technologies face innovation barriers that potentially limit their diffusion. An agent-based model is developed to explore the effect of imperfect agent information and split incentives barriers that current shipping models omit. A transitions perspective is adopted to analyze the diffusion of Flettner rotor technology in time charter drybulk shipping with the model. Simulation results are more conservative compared to those models and show how barriers impact the diffusion of rotor technology, even on favourable shipping routes. The simultaneous introduction of carbon pricing and demonstration projects greatly increases CO2 emission reductions to 2050 relative to either policy introduced in isolation.feasible add-on technology to conventional oil fueled propulsion technologies (Nelissen et al., 2016).Based on this MLP conceptualization, an agent-based model (ABM) is developed to explore the effect of barriers on Flettner rotor technology diffusion in the time charter drybulk shipping sector on a route with favourable wind conditions. The rest of the paper is structured as follows. Section 2 provides the background to the MLP, niche-based innovations and an overview of the international shipping context and modelling work performed to date. Section 3 develops the ABM and presents simulation scenarios and sensitivity analysis results. Section 4 discusses results, limitations of the study and future work and section 5 concludes the paper. BackgroundSection 2.1 outlines briefly the MLP and discusses the extensive literature on transitions and niche. This is used in section 2.2 to conceptualize the shipping transition and the barriers that alternative propulsion technologies face. Section 2.3 provides an overview of modelling applications in the shipping sector to contextualize the model developed in this paper.

“…Moreover, the implementation of energy efficiency management needs to extend for shipping sectors. The measures of high implementation have been concentrated for over thirty energy efficiency and CO 2 emission reduction technologies [7]. Winnes and Fridell had studied two fuel oil qualities-heavy fuel oil (HFO) and marine gas oil (MGO) for four stroke main engines [8].…”

In the shipping transportation industries, they brigh a lot of economical values with rising a number of fleets. Unfortunately, this development always encloses to the environmental pollution issue. "International Maritime Organization (IMO)" has been adopted all member states of nations that are being operated and managed the ocean by means of giving out the "International Convention for the Prevention of Pollution from Ships (MARPOL 73/78)". In where, the exhaust gas cleaning system has been known as an optimal solution to reduce SO x emissions from diesel engine exhaust gas on board. In this article, the structures of sulphur scrubber exhaust gas cleaning systems have been researched along with their cleaning methodology. Based on the working performance of their systems on ship, there is a comparison of efficiency that it will help ship-owners selected effectively in ship operation. The results of this article have identified that the reduction of SO x gas emission reaches to 95% and PM (Particulate Matter) reduction efficiency aims 60%. So, the use of Scrubbers to reduce sulphur content in marine diesel engines approaches reliably in ship operation nowadays
