2.3.1 A classification demarcation plan is to be submitted for approval that
identifies any boundaries of classification.
2.3.2 The unit will encompass a split between the traditional Classification
scope and that nominally described as process plant. It is noted that particularly
with respect to new build projects the differentiation can lack clarity and it is
not purely a function of location of the systems on the unit. Accordingly, a list of
items to be considered under Classification requirements is to be developed, this
may be extracted from the project equipment list, associated P&ID’s and shall be
agreed with LR. The equipment list shall also be used to identify those systems
which fall inside and outside of Class and will form the basis of a classification
demarcation plan for the unit.
2.3.3 It should be noted that the location of an item rather than its function
can influence the decision for inclusion within the Classification list of items. By
example a tank serving a topsides process, that would normally be considered part of
the topsides process plant, should be considered a Class item if it is located
within the hull and adversely impacts the overall risk.
2.3.4 It should be noted that the forgoing has been written with facilities
encompassing a significant process plant in mind. However, it is recognised that
other facilities e.g. crane barges will also benefit from this approach.
Accordingly, in these instances, an equipment list, associated P&ID’s, if
appropriate, and plot plan are to be submitted for review.
