Sakhalin II Phase 2 - Technical Support for Pipeline Route
Feasibility and Slope Study
Project Introduction
Sakhalin Energy Investment Company Ltd is
developing a multi-billion dollar pipeline project located on the
northwest Pacific rim. This is intended to transport offshore oil
and gas from the north of Sakhalin, which is ice-bound in winter,
to the south of the Island where climatic conditions permit
year-round shipping access to an export facility.
Project Background
The onshore works comprise a contract for the
design and construction of twin 782km long pipelines and associated
infrastructure passing through varied terrain and complex geology
in a seismically active area subject to climatic
extremes.
Project Scope
Scott Wilson was commissioned initially to
carry out a desk study, aerial photograph interpretation, detailed
field mapping and preliminary geotechnical assessment for route
location and landslide assessment purposes along the 120km length
of alignment through the Makarov Mountains section. Subsequently,
the brief was extended to encompass review of the Contractor’s
designs for mitigation works, observation of supplementary ground
investigations and ground monitoring works, analytical checks and
the preparation of conceptual alternative mitigation works where
necessary
Value Adding Project
Achievements
Through the deployment of these geotechnical
experts on this challenging project Scott Wilson has assisted the
client to tackle the exceptionally demanding ground risks along the
route. Key ingredients to this success included Scott Wilson
arranging both for staff to be temporarily resident on Sakhalin
itself and also for short-term visits of senior personnel and
specialists, all experienced in one or more of the fields of
geomorphology, engineering geology, hydrology, geotechnics and
ground engineering, and the design and construction of major civil
engineering works.
Scott Wilson has provided advice and
observational assistance to the Client. This has involved detailed
engineering geomorphological mapping, logging of trial pits and
construction exposures, geotechnical modeling and analysis.
