Making shipping more carbon-friendly? Exploring ship energy efficiency management plans in legislation and practice

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

“…This study shows that energy-saving measures are mostly determined with the involvement of the ship's personnel which is the desired outcome. To make the SEEMP useful as a dynamic and practical tool which is also in-tended by IMO, participation of the seafarers in identifying and meeting goals and objectives influencing the decisionmaking process has great importance in energy-saving activities (Hansen et al, 2020). Participation of shore personnel and the seafarers is critical in order to achieve the goals.…”

“…The study demonstrates that there are differences between the planned measures and their real practice achievement onboard. This gap might be a result of a lack of understanding of operational practice, which was observed by Viktorelius & Lundh (2019) and Hansen et al (2020). The energy efficiency gap has been defined by Jaffe & Stavins (1994) as a difference between the calculated optimum energy use and how much it is actually used.…”

“…In addition, the seafarers exemplify shipboard operations so the company must pay attention to involve seafarers and use their feedback in developing the content of the SEEMP for a particular ship. This would give the shipping company valuable insight into day-to-day operations and ensure it set more meaningful objectives (Hansen et al (2020).…”

Prediction and optimisation of fuel consumption for inland ships considering real-time status and environmental factors

“…It also reflects the operating status of ship engines (Schaub et al, 2019), which makes it an important monitoring variable in modern intelligent ship systems and a key parameter to control in unmanned ship navigation systems (Wright, 2019). On the other hand, the ship fuel consumption is also closely related to exhaust emissions and is an important indicator for pollution research and environmental monitoring (Van et al, 2019;Hansen et al, 2020). Therefore, the ship fuel consumption has become an important research topic for many scholars and practitioners.…”

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

“…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]).…”
