“…For instance, for trim optimization, the seafarers must be familiar with weight distributions with exact precision as well as the optimization tool (Kitada & Ölçer, 2015a). Some studies also showed that seafarers have insufficient knowledge (Banks et al, 2012;Viktorelius & Lundh, 2019) which result in a communication issue relating to fuel-saving activities (Dewan et al, 2018;Rasmussen et al, 2018;Johnson et al, 2014) defined as a barrier to ship energy efficiency (Johnson et al, 2014).…”

“…Banks et al (2011) suggested a model course on energy efficiency, stating that the new regulations on energy efficiency on ships will directly affect the working patterns of seafarers and that training should be given in this regard. Rasmussen et al (2018) argued that seafarers should be trained to gain more energy efficiency skills, as they are the most important link in the system. In their study on energy efficiency with the bridge simulator, Jensen et al (2018) stated that seafarers can focus on energy efficiency issues by installing technical equipment and raising their awareness.…”

“…Seafarers are responsible to operate the ship, generally distant from shore offices, and are therefore essential to the successful operation of energy efficiency measures affecting fuel consumption. The involvement of seafarers is needed for adapting many operational measures such as the decision for speed optimization or weather routing for energy efficiency (Kitada & Ölçer, 2015a;Rasmussen et al, 2018;Banks et al, 2012). Due to the critical role of seafarers in daily operational practices, enhancing their energy efficiency awareness and knowledge is important to increase energy efficiency and achieve energy savings onboard a ship.…”

Determining the awareness and knowledge of officers towards ship energy efficiency measures

Improving energy efficiency practices on ships is crucial for both economic and environmental purposes. Both technical and operational applications are made to increase energy efficiency on ships. The success of energy efficiency applications on ships depends on the effective work of seafarers. Therefore, awareness and knowledge about the energy efficiency of seafarers should be enough. The aim of the study is to determine the awareness and knowledge level of seafarers on energy efficiency on ships and to evaluate energy efficiency practices in maritime transportation companies from the perception of seafarers. In the study, the survey method was used. As a result of the survey, it was found that the knowledge level of the seafarers on ship energy efficiency was low, almost half of them did not receive energy efficiency training but they were informed about the importance of the issue. At the end of the study, it was evaluated that the awareness and knowledge level of officers should be increased in order to improve energy efficiency on ships and suggestions on this issue were determined.

“…Many other studies have also shown that EE operation of the vessels can become irregular and complex as the picture is influenced by multiple actors and their relationships. There could be involvement of multiple stakeholders [21], goal or demand conflicts with EE operations (thus limiting the "maneuverability" for officers on board) [22], gaps in inter-department collaborations [23,24], social barriers in communities of practice [12,25], lack of trust between ship and shore organizations (thus downgrading the organizational practice) [26], etc. These insights in the EE domain can be captured by ethnographic research or its associated "thick data" approaches [27] (i.e., "a sticky stuff that is difficult to quantify" but "offers incredible depth of meanings and stories" [28]).…”

From Ethnographic Research to Big Data Analytics—A Case of Maritime Energy-Efficiency Optimization

et al. 2020

The shipping industry constantly strives to achieve efficient use of energy during sea voyages. Previous research that can take advantages of both ethnographic studies and big data analytics to understand factors contributing to fuel consumption and seek solutions to support decision making is rather scarce. This paper first employed ethnographic research regarding the use of a commercially available fuel-monitoring system. This was to contextualize the real challenges on ships and informed the need of taking a big data approach to achieve energy efficiency (EE). Then this study constructed two machine-learning models based on the recorded voyage data of five different ferries over a one-year period. The evaluation showed that the models generalize well on different training data sets and model outputs indicated a potential for better performance than the existing commercial EE system. How this predictive-analytical approach could potentially impact the design of decision support navigational systems and management practices was also discussed. It is hoped that this interdisciplinary research could provide some enlightenment for a richer methodological framework in future maritime energy research.

“…Numerous factors thus influence the fuel consumption of a ship, which often varies significantly during and between voyages. This complexity, including the lack of knowledge on the ship and route specificity of energy consumption, makes it particularly difficult for crews to learn and develop optimal work practices (Rasmussen et al 2018;Viktorelius and Lundh 2019). Implementation and use of information technology to monitor energy use is thus critical for efficient operations.…”

The paper offers an analysis of how an energy-monitoring system was implemented and eventually adopted by the crew members in a shipping company. It illustrates how the social process of enacting the system as a collaborative technologyin-practice, enabling a significant reduction in energy consumption, was contingent on the negotiation of meaning and mutual learning among crew members in their community of practice. The case study contributes to the literature on the relation between information technology, organization and energy efficiency by investigating the socially situated nature of technology implementation and work practice change. The findings' implications for the role of information technology in improving energy efficiency in shipping are discussed.
