In Denmark venting of gas is assumed to be negligible because controlled venting is send through
the gas flare system.
Ships
This source includes the transfer of oil from storage tanks or directly from the well into a ship. This
activity also includes losses during transport. When oil is loaded hydrocarbon vapour will be displaced
by oil and new vapour will be formed, both leading to emissions. The emissions from ships
are calculated by equation 3.5.5.

where EMF ships is the emission factor for loading of ships off-shore and on-shore and L oil is the
amount of oil loaded.
Oil tanks
The emissions from storage of raw oil are calculated by equation 3.5.6.

where EMF tanks is the emission factor for storage of raw oil in tanks.
Activity data
(3.5.5)
Activity data used in the calculations of the emissions is shown in Table 3.29 and is based on information
from the Danish Energy Authority (Danish Energy Authority, 2004a and 2004b) or from
the green accounts from the Danish gas transmission company DONG (DONG, 2004).
