Engineering and technology
Aker Solutions’ leading experience and technology combined with understanding
client requirements is key to every project.
We bring together professionals across
a diverse range of engineering and
oilfield domains, ranging from front
end studies to environmentally driven
modifications. The unmatched scale of
our cross-discipline expertise ensures
that every angle is considered.
Over the past 15 years Aker Solutions
has delivered more than 400 umbilicals
to some of the world’s most challenging
fields, from harsh environment to
ultra-deep, high-pressure reservoir
conditions.
Our umbilicals are always designed
with this in mind; the long lay length of
the components and the components
supported in channel elements give the
lowest possible load exposed to tubes,
cables, power cores and fibre optical
elements.
Aker Solutions utilise various
technologies to provide the best
solution for each project:
Carbon fibre rods in the cross section
control the strain of the components
and improve fatigue properties
Suspension of the power cores
below the fatigue exposed section
of dynamic umbilicals eliminates the
combined bend and tension and
significantly reduces contact force
Steel tape armour provides ballast
with high fill factor and increased
mechanical protection
Profile matrix designed to meet
specific requirements for crush and
impact capacity
Polymer properties satisfy
temperature and design life criteria
Our umbilical design with components
individually supported in channel
elements creates a wide range of
possibilities for arranging the crosssection.
The channel elements easily
facilitate incorporation of functions like
fibre-optical monitoring and strength,
and weight components like wires and
composite fibre rods.
The design of the termination and
ancillary equipment is a significant
part of the project. Terminations must
interface with equipment supplied by
external parties like subsea connection
systems and platform infrastructure.
They are designed to minimise the
dimensions and weight, while ensuring
sufficient space and access for the
termination work.
The installation is often the most critical
phase of an umbilical’s life cycle and
the complex issues related to the
installation need proper preparation.
The load imposed on the umbilical
during handling and installation and the
load limitations of the umbilical system
must be thoroughly communicated in
interface documents. The design of the
umbilical, terminations and ancillary
equipment must therefore reflect the
installation equipment and procedure.
