Because the latest version of Part 4 requires additional load to allow for tolerances in rubber. Not reasonable increase load factors since loads are highly predictable and more factors are taken into account

BS 6349 Essential Update for the Ports and
Limited guidance at present The whole of seismic design covers many issues which Part 1.2 does not cover c over New seismic guidance will be included in other parts For now, all we do is define the seismic action (ground motion)
Seism ismic ic iss issue ues s
BS 6349 Part 1.2-- Action s 1.2 The Final Stretch!
BS EN 1998 parts 1,2 and 5 are the key references
Definition of seismic guidance is structured to that.
PIANC produced a document WG34 in 2001
Most recent guidance is in ASCE 61-14.

There is goodwill from the UK seismic community to orient maritime seismic design towards EC8 But few people with the competence to organise it!
Seism ismic ic iss issue ues s
EC 8 is based on 2 levels of earthquake
BS 6349 gives guidance on assessing assessi ng them
BS 6349 Part 1.2-- Action s 1.2 The Final Stretch! Steve Osbor Osbor n
Ground motions have similar return periods to those in EC8 rather than PIANC
