EAST-FRIGG

History :
The field was put onstream in 1988 in a water depth of 100 metre. In 1997 the field was
shutdown and in 1999 the production wells were decommissioned, plugged and
abandoned. The field was located 18km from the Frigg complex.

A technological pioneer project developed for diverless installation and operation. The
first subsea field on the Norwegian shelf with remote controlled wells in several clusters.
The East-Frigg development was based on modular principles as the first of its kind.

Design Parameters :
EF installations were designed for a minimum flow-rate of 1.25MSM3/d and a maximum
flow-rate of 6.5MSM3/d. The maximum working pressure rating was 345bar. Bottom hole
flowing temperature approx 62 deg C, Wellhead hole flowing temperature approx 35-40
deg C, Wellhead static temperature 4-6 deg C. Design was based on 5 subsea production
wells located over 2 production templates PSA & PSB. For reduncy reasons and to
minimize intervention it was decided at this time to include 2 off Xmas trees in series
for each well. 1 off Vetco and 1 off ”Well Jumper Module tree Cameron.

There were 3 wells on PSA and 2 wells on PSB , the two production stations produced to a
central manifold station (CMS) located halfway between the 2 production stations which
were approx 3km from each other. Production flowed via the CMS to Frigg where it was
metered and treated.

Status :
Currently stored in Tananger Norway. Has been maintained throughout delivery installation
and return onshore.

Major assemblies comprises :
5 off Vetco Xmas tree and tree cap assemblies, each gas production tree comprising 18 ¾”
SG-5 wellhead connector, integral with 5” x 2” , 5,000psi working pressure valve block, with
fail safe closed valves, equipped with visual position indicators and overrides. Manifold spool
flanged to block, production spool, Xmas tree guide frame, control system components and piping.
Complete tubing hanger system including hydraulic running tools, adaptors, VAM-Hydril x over
riser couplings, emergency recovery tools, orientation/ inspection tools. Control systems for THRT.
Intervention amd maintenance systems incl; flowhead, 5,000 riser system, EDP/ LRP, hydraulic
control system, adaptors, test stumps, remote killing equipment, guide bases, hubs, sealing
caps, dummy Xmas tree etc

6 off Kongsberg/ Cameron WJM (Xmas trees)

Module M35 Description :
The module was delivered, installed and commenced production in 1993. Design life was
30 years. Production ceased as with Lille-Frigg in 1999. The purpose of the module was to
faciltate handling of process for both Lille-Frigg and the Oil producing satellite platform Frøy.
(Note Frøy platform has been returned onshore and been disposed of)
Dimensions of the module are 40.5m length x 24m width x 24.8m height. Weight for single lift
is 3216 ton. The module is located on the TCP2 platform located within Frigg process handling
complex.

The module is equipped with a pedestal crane with working radius at 36 tons between 9-30
metres and 12 tons with maximum radius of 60 metres. This crane carried out material handling
for all of the TCP2 platform, which meant that TOTAL could at the time dispose of the rest of the
smaller cranes which were out of date.
