Recently the climate-abusing effects of exhaust gases
from combustion processes have been increasingly focused. This is underlining
the importance of improving the energy efficiency. Nowadays, fishing fleet is in
most cases not efficient because of outdated technology. Maintaining an
adequate level of energy efficiency requires a continuous monitoring of the
energy profile of the vessel. Any causes of energy inefficiency can be
identified, being able to act on them promptly and effectively. A proper system
of energy use monitoring is therefore essential for maintaining high-energy
efficiency. Once energy use has been related to each operating condition,
fishers can minimize fuel use. Energy efficiency in fisheries can be investigated
through Energy Audit, which allows obtaining an extensive energy profile of the
fishing vessels monitored. Vessel Energy Audit assesses the energy consumption
of each energy user (e.g. propulsion system, electric- and hydraulic-user). Energy
audits have been conducted for fishing vessels, which lead to recommendations
for improved efficiencies to solve present and possible future fuel cost
increases.

近年来，燃烧过程排放废气所引发的气候破坏效应愈发受到关注，这也凸显了提升能源利用效率的重要性。当前，多数捕捞船队因技术老旧而能效低下。维持合理的能源效率水平，需要对船舶的能耗特征开展持续监测，如此便可识别出所有能效低下的诱因，并及时采取有效应对措施。因此，一套完善的能源使用监测系统，对维持高能源效率而言至关重要。一旦将能源消耗与船舶各运行工况关联起来，渔民即可最大限度减少燃油使用量。渔业领域的能效水平可通过能源审计（Energy Audit）进行研究，该方法能够获取受监测捕捞船舶的全面能耗概况。船舶能源审计会评估各类能源消耗终端的能耗情况，例如推进系统、电力及液压用能设备。目前已有针对捕捞船舶开展的能源审计工作，其结果可提出能效优化建议，以应对当前及未来可能出现的燃油成本上涨问题。
