lubricants, due to various factors
such as the absence of compre-
hensive data gathered through
actual use and observation over
time.
Efforts are continuing in
this area. So far, there have been
positive results. The bar graph in
figure 2 compares two market-
leading brands of conventional
lubricants with an EAL in terms
of oxidation times.
Such improvements would
slowly and steadily bring EALs
as the preferred choice, and over
time, the acceptance of bio-lubri-
cants could become more wide-
spread and extend beyond the
mandatory regime in U.S. waters
and the VGP requirements.
原始设备制造商（OEM）在推荐
EAL时也有所保留，这是因为缺乏
实际使用中的全面数据，观察时
间太短等。
在这个方面的努力还在继续。
到目前为止，结果令人鼓舞。图2

这种提升将缓慢而稳定地使
EAL成为更受欢迎的选择，随着
时间的推移，对生物润滑油的接
受度将超越有强制要求的美国水
域和VGP要求。
总结
最新版的VGP是船舶污染控制
和环保领域的一大进步。同时，美
国环保署也考虑一些旧船从常规
润滑油转为EAL过程中的实际困
难，因此他们制定了一个较为合理
的时间进度，使之能在下一次大修
时进行换油。对技术上无法使用
EAL，且向权威部门作出合理解释
的船只，他们还给予了豁免。
最后，可以这样说，新的VGP较
早期的版本是一大进步。在各洲各
国，防污和控污标准应该逐步提
高。只有这样才能提升船舶业使用
生物润滑油的意识。

Summary
The latest version of the VGP
is a welcome step in the area of
marine pollution control and
beneficial for the environment as
a whole. It’s also worth noting that
the EPA has taken into account
some of the practical difficulties as-
sociated with the changeover from
conventional lubricants to EALs
instantly, so they have drawn out a
reasonable time frame for existing
vessels by allowing them to do
the required changes at the next
drydock. They have also exempted
cases where use of such oils is
technically infeasible and proper
explanation can be given for the
same to the authorities concerned.
Finally, it can be said that the
new VGP is certainly an improve-
ment over the earlier version, and
there should be a gradual effort in
raising the benchmarks of pollu-
tion prevention and control across
all nations and continents. This
would help to heighten awareness
about the use of biolubricants in
the marine sector.
