LAM-B Wellhead Platform
GeneralDescription>LAM-B platform is located at LAM field in the Caspian Sea about 30 km offshore
Cheleken area in Turkmenistan. The water depth in the field varies from 16 to 30 m.
The type is unmanned offshore fixed wellhead cum production platform provided with
8 conductor slots to drill 8 new wells each to be completed as dual string producer
(8 conductors/16 wells).
A brief description of the automated LAM-B offshore fixed wellhead cum production
platform plus major associated facilities is given below: the substructure consists
of two jackets fixed in design position by piles driven into the sea bed and joined on top
by means of support framing. Topside consists of a drain deck, main deck, wire line deck,
one cargo deck and corresponding fire-walls.
The platform accommodates 8 nos. of 30” conductors in two rows arrangement with
well spacing of 2.8 m x 4.9 m x 2.8 m and 3 m spacing between rows. Enough spacing
is provided between X-mas trees to allow for safe operation and maintenance of X-mas
trees. The platform is planned such that the wells array on one edge of the platform
so as to use jack up rig. Riser and its clamps to the platform: 12” for the pipeline from
LAM-B to LAM-28 (not included into contractor’s scope of work). The platform is provided
with two boat landings, topside facility to accommodate 16 wells and is equipped with
process and other equipment as per Client’s order.
Overview>
The project on EPC basis included design, engineering, procurement,
steel structures fabrication at fabrication yard in Astrakhan, Russia,
load-out of ready modules and jackets on barge, transportation
to Turkmenistan, offshore installation on location using marine spread
consisted both of own and chartered support fleet, connection
of platform modules, finalizing LAM-B wellhead process package,
driving of 8 conductors, start-up, testing and commissioning
of process equipment and all auxiliary process communications
and networks.
Design has been carried out by the NCG Services in-house design
and engineering team of NCGS Group. The project was inspected and
certified by Germanischer Lloyd.
Engineering included organization, coordination, maintenance of the
project and internal technical supervision over the construction.
All supplies and deliveries have been supervised by commercial
department and procurement and logistics department. All equipment
and materials required for fabrication of steel structures and piping
has been mainly supplied by recognized and approved international
companies.
To provide high quality output continuous technical supervision
over construction has been carried out by third party inspection:
Germanischer Lloyd representative.

Smart Solutions>The project pioneered the use by our design and engineering team
new specialized 3D modeling software by Bentley Systems in their work
for all project segments: from steel structures and process, instrumentation,
power supply, heat tracing of pipelines and gauges to life saving and firefighting
equipment.
Being a new experience to our engineers this required much effort
to quickly train personnel and nail down all the tools and tweaks offered by
this sophisticated software to do the job. Yet, it brought in great results.
Owing to this 3D design platform which enabled us to find spare tunnels
for piping installation, as well as to detect collisions with existing objects etc.,
not only this project has been successfully implemented, but it also contributed
a lot to optimize all the following projects making design and engineering
a lot smarter, easier and versatile.
Moreover, LAM-B project became a part of a competition held by Bentley
Systems where we managed to demonstrate our professionalism and join
the leaders.
