2. Capability Overview
We at JBEIL Subsea re extensively involved in
the engineering for submarine Pipelines and
SURF (Subsea Umbilicals Risers & Flowlines).
Route Selection Study
Work profile includes Pipeline Mechanical De-
sign, Pipeline Flow Simulation, Pipeline Allow-
Hydraulic Analysis
able Free Span Analysis, Bottom Roughness

Also, we are involved in the technical bid prepa-
ration, review of specification, technical bid Global Buckling Analysis
evaluation and project management activities.
End Expansion Analysis
We are very well conversant with software Stress Analysis
packages like :
Pipelay Analysis
OFFPIPE
SURF Lay Analysis
ORCAFLEX
CAESAR II Pile Design
PIPESIM
SACS Pile Drivability Analysis
STAAD III
AutoCAD Heavy Lift Analysis
SPM Related Analysis

3. Engineering Services
Route Selection, pipelines are generally unable to follow the direct
traight line route for many reasons, due to land/seabed obstructions,
crossings, land/seabed.
Hydraulic Analysis, pipeline diameter is sized for peak flow and
ensures that flow conditions and pressure drop are within acceptable
ranges. However, one must also check for low flow condition in case
his leads to laminar flow and corrosion at the bottom of the pipe will
occurred.
Mechanical Design, the principle for wall thickness sizing is to make the
wall thick enough to contain the maximum allowable operating pres-
sure, although there are many factors to take into account which may
lead to the selection of a thicker wall.
On-bottom Stability Analysis, this analysis is performed to ensure that
the pipeline is stable on the seabed under the influence of extreme
environmental conditions.
Spanning Analysis, unsupported pipeline (Free Span Pipeline) be-
tween two points will be subjected to a number of loads. These com-
prise bending under its self weight, loads imposed by pressure, hydro-
dynamic loading, etc.
Global Buckling Analysis, this analysis is performed to analyze pipe-
line susceptibility to both lateral and upheaval buckling. End expansion
analysis this analysis is performed to calculate pipeline expansions
due to temperature, longitudinal stress, etc.
Stress Analysis, this analysis is performed to check pipeline system
stresses such as hoop stress, bending stress, longitudinal stress, etc
against their allowable stress limits stated in design code.
Pipelay Analysis, this analysis is performed to check layability of the
Pipeline in S-lay or J-lay methods. This helps to ascertain the Derrick
Barge or pipelaay vessel adequacy for pipelay operation. The Pipelay
Manual provides max. wave Hs, required tension, barge roller support
configuration etc for the entire pipelay operation. The analysis is done
using OFFPIPE (Static & Dynamic).
SURF Analysis, this analysis is performed using the software - Orcaflex.
It determine the required lay parameters (i.e. limiting seasates, re-
quired tension etc.). Suitable modifications & precautions can made
and taken to be with in Design Limits of the SURF product.
