Abstract

The International Maritime Organization's (IMO) decarbonization targets necessitate adopting alternative fuels. Liquefied Natural Gas (LNG), regulated by the International Code of Safety for Ships Using Gases or Other Low-Flashpoint Fuels (IGF Code), offers potential emission reductions but faces debates regarding methane slip and cost-effectiveness. This meta-analysis synthesized 48 peer-reviewed studies (2015–2024) following PRISMA guidelines. Random- effects models quantified LNG’s performance versus conventional fuels (HFO/MDO) in emissions (CO₂eq, SOₓ, NOₓ, PM), economics (CAPEX/OPEX), and safety. Heterogeneity was assessed via I² statistics. LNG reduces SOₓ by 98% (95% CI: 96–99), NOₓ by 25% (18–32), and PM by 93% (88–97). Net CO₂eq reduction is 12% (5–19) after methane slip adjustment (0.2–5%). CAPEX is 25% higher (SMD = 1.8; 1.5–2.1), but OPEX is 22% lower (SMD = -1.2; -1.8 to -0.6). Safety incidents are 1.8× more likely (OR = 1.8; 1.2–2.7), mitigated by IGF-compliant training (OR = 0.6; 0.4–0.9). LNG achieves immediate air quality benefits but requires methane slip abatement for climate goals. Policy priorities include bio-LNG blending and global bunkering standardization

Abstract

Passanger ship play an important role in supporting community activities. During voyages, safety equipment is crucial because it must meet the standards set by SOLAS. However, in practice, there are often problems with safety equipment and the skills of the crew themselves. This study aims to identify the factors, constraints, and efforts that influence the skills of crew. The method used in this study is descriptive qualitative, with the research location on the KM. Sangiang ship. The data used is primary data obtained directly through interviews and observations, while secondary data is obtained from ship documents or related reports on board the ship. This study also employed data collection tecchniques such as observation, interviews, and documentation, as well as triangulation data analysis. The result of this duty indicated that the factors and constraints that affect crew skills are crews understanding of lifeboat lowering procedures, discipline, and lifeboat readiness. Efforts made to overcome obstacles include conducting evaluations after drills and improving communication and coordination among crew members.
