BJ Services awarded multi-million dollar Stolt contract
Posted: 7 July 2003
Services to be carried out on offshore gas gathering system
on behalf of Shell Petroleum Development Company S.A. in Nigeria
BJ Process and Pipeline Services (BJ PPS) has been awarded a multi-million
dollar contract by Stolt Offshore Services S.A. to provide pipeline
pre-commissioning services on several sections of Shell Petroleum
Development Company’s new offshore gas gathering system (OGGS)
in Nigeria.
During the coming months, BJ PPS will provide flooding, cleaning,
gauging, hydrotesting, de-watering, air-drying and nitrogen packing
services on the OGGS 32” trunkline, 24” spurline and
16” spurline.
Pre-commissioning to be carried out on and offshore
The first phase of the OGGS project, which has commenced,
is to pre-commission the 32” trunkline. Already, BJ PPS has
successfully flooded, cleaned and gauged the offshore section of
this trunkline.
BJ PPS is carrying out services both on and offshore. The pipeline
will be tied in to the unmanned OGGS RP-A platform, located approximately
18km west southwest of South Forcados, where BJ PPS will work from
a support vessel alongside the platform.
This trunkline runs approximately 268km southeast along the Nigerian
coast to Bonny Island, where it reaches the shore and runs onshore
8km inland to the NLNG plant on the island.
The onshore pipeline contractor will then tie-in the pipeline to
the NLNG plant after all necessary procedures are completed.
Phase II involves the pre-commissioning of the 24” spurline
that lies between the OGGS RP-A platform and Forcados Yokri, located
approximately 88km north of the RP-A.
The third and final phase is to pre-commission the 16” spurline
between the RP-A and South Forcados, which measures approximately
18km.
Both Phase II and III will be carried out from a support vessel
positioned alongside the RP-A, and on the respective beaches at
Forcados Yokri and South Forcados.
BJ PPS will leave the pipeline on the beach sealed, following completion
of all related pre-commissioning services.
BJ PPS will service the Stolt Offshore contract by drawing upon
its specialist equipment. Of particular note are plans to use the
BJ nitrogen membrane unit to perform nitrogen-packing services,
given the low availability and high price of nitrogen in the region.
By doing so, BJ PPS will be able to provide this service at a considerable
cost-savings.
Further, the operation will be supported by personnel at the BJ
PPS base in Port Harcourt, Nigeria and its world headquarters in
Aberdeen, Scotland.
Largest Pipeline Pre-commissioning Operation in West Africa
The award of this contract further solidifies BJ PPS’s
presence in West Africa and North Africa, as well as its relationship
with Stolt Offshore.
In recent years, BJ PPS has carried out pre-commissioning services
for Stolt Offshore on the Amenam-Kpono Field, EA Field, Girassol,
Lombo East and Mossgas projects in West Africa, and the Scarab/Saffron
project in Egypt.
“As this is the largest pre-commissioning operation currently
taking place in West Africa, we are very excited to be playing such
a critical role. With our pre-commissioning experience in Africa
working on behalf of Stolt Offshore, we are once again working very
hard to deliver outstanding service in all respects,” according
to John Adams, general manager of BJ PPS.
“With our commitment to quality and safe working practices,
we will ensure that all work is carried out with great care, in
order that Shell’s offshore gas gathering system will operate
smoothly and safely,” he added.
BJ Services Company (BJS-NYSE, CBOE) is a leading provider of pressure
pumping and related oilfield services to the petroleum industry.
The company operates in every major oil and gas producing region.
