Through visual inspection for underwater, above-water and topside
structure of offshore installations, and using different inspection methods,
such as detection/video, measurement of marine growth, thickness measurement,
NDT of critical areas, anode survey, catholic protection potential measurement,
seabed detection, CCS provides scientific and reasonable basis for safe
service, repair and modification of offshore installations combined with
special software of offshore structural and hydrodynamic analysis.
Based on the model established
through safety assessments, CCS provides technical support services for owners
during the whole service life of offshore installations. By tracking the
service conditions of offshore installations and the results of regular surveys,
CCS will update the calculation model in order to reflect the actual status of
offshore installations timely. When the offshore installations need to be
repaired, modified or suffer sea damage, CCS will determine what measures need
to be taken to make repairs through a science-based decision-making process,
that is rapid and will bring direct benefits to owners.
1) Assessment object and content
Assessment of global strength,
local strength, tubular joints punching shear strength, pile foundation bearing
capacity, risk of crack and residual fatigue life of the fixed platforms under
all conditions, including simple platform, jacket platform, tension leg
platform, guyed tower platform and single point mooring platform.
Assessment of global strength,
local strength, hydrodynamic performance, risk of cracks and residual fatigue
life of the mobile platforms under all conditions, as well as calculation and
checking of intact stability, damage stability, anti-capsize stability, anti-sliding
stability, descending and ascending stability of the platforms, including jack-up,
submersible, column-stabilized and surface-type platforms.
Assessment of global strength,
local strength, hydrodynamic performance, risk of crack, residual fatigue life,
as well as calculation and checking of intact stability, damage stability and
load line of FPSOs under all conditions.
Assessment of global strength,
local strength and fatigue strength of subsea pipeline.
Calculation of cable tension,
