ENVIRONMENTAL STATEMENT BARDOLINO DEVELOPMENT

Bardolino Development Environmental Statement
The production separation train consists of a single three-phase separator and a plate
coalescer.
3.6.2 Modifications to Howe infrastructure
Minor modifications will be required to the Howe subsea infrastructure as a result of the
Bardolino project. A new subsea electrical distribution box (EDB) and a new subsea valve
skid will be installed at the Howe Pipeline Tie-in structure (PTS). A new regulator and
associated valves will be fitted to the Howe hydraulic power unit (HPU). These modifications
will entail the presence of a DP DSV at Howe for approximately 15 days during June 2009.
The atmospheric emissions from these vessel operations have been calculated and are given
in Table 3.6.
3.6.3 Topsides Modifications at Nelson
To accommodate the introduction of produced fluids from Bardolino it is necessary to add a
H2S scavenger package to the Nelson topsides facilities. Work will involve the addition of an
H2S scavenger storage and injection skid with associated pipe work and on-line analysers.
This work on the topsides will be undertaken using normal supply vessel transport to Nelson
and no additional vessel trips or days will be required.
3.6.4 Production Start-up
Production start-up plans are yet to be detailed. Initially, the well will be brought on-stream up
to the choke valve in accordance with normal Shell well start-up procedures.
