4.1.2 Recognizing that there are a variety of
options to improve efficiency – speed optimization, weather
routeing and hull maintenance, for example – and that the best
package of measures for a ship to improve efficiency differs to a
great extent depending upon ship type, cargoes, routes and other factors,
the specific measures for the ship to improve energy efficiency should
be identified in the first place. These measures should be listed
as a package of measures to be implemented, thus providing the overview
of the actions to be taken for that ship.
4.1.3 During this process, therefore, it is important
to determine and understand the ship's current status of energy usage.
The SEEMP then identifies energy-saving measures that have been undertaken,
and determines how effective these measures are in terms of improving
energy efficiency. The SEEMP also identifies what measures can be
adopted to further improve the energy efficiency of the ship. It should
be noted, however, that not all measures can be applied to all ships,
or even to the same ship under different operating conditions and
that some of them are mutually exclusive. Ideally, initial measures
could yield energy (and cost) saving results that then can be reinvested
into more difficult or expensive efficiency upgrades identified by
the SEEMP.
4.1.4 Guidance on Best Practices for Fuel-Efficient
Operation of Ships set out in chapter 5, can be used to facilitate
this part of the planning phase. Also, in the planning process, particular
consideration should be given to minimize any onboard administrative
burden.
