WHY INSPECTION:
Accurate site information is essential for successful offshore positioning.
An exposed cable or a free-span pipeline can easily result in a costly breakage, so Subsea Hundred Global provides a range of suitable methods for conducting route inspections.
Combined with time series analysis, we can visually demonstrate protection requirements due to currents, tides and movement of sediment.
We deploy specialized equipment such as ROVs for detecting, tracking, and mapping using Multi-bean, Side Scan Sonar and under-water videos to follow the route as accordingly and a remotely operated crawler for shallow water environment.
Subsea Hundred Global carries out pipeline inspection surveys to detect free-spans, damage, defects, leaks, erosion or pipeline movement, require innovative technology and experience.

INSTALLATION, REPAIRS & MAINTENACE (IRM) & INSPECTION
REAL TIME MAGNETOMETER DATA ACQUSITION WITH ALTIMETER DISPLAY
Detailed corridor mapping provides the essential raw data for the
design and installation of sub-sea linear structures, such as oil and gas
pipelines, flow lines and umbilical.
Detailed corridor mapping provides the essential raw data for the design and
installation of sub-sea linear structures, such as oil and gas pipelines, flow lines
and umbilical.
Seabed sampling and testing tools - such as grab samplers, vibro-corers and
Cone Penetrometer Testing (CPT) units - can be combined with high resolution
seismic and geophysical data to provide accurate information on the structure
of the seabed. This data is essential for providing a correctly engineered
design that avoids the often-considerable costs associated with over-
engineering for uncertainties.

We work closely with our clients to establish the parameters and objectives of their
projects, also contributing vast international experience of IRM (Inspection, Repairs & Maintenance) and decommissioning projects.
We combine this with pioneering technological innovations and substantial in-house
resources. These include our world class subsea acoustic pipeline inspection services,
with the latest generation of ROTV. However, our Risk Based Inspection methods, are
designed to increase uptime, reduce maintenance costs and further protect the environment.
Our aim is to provide a wholly integrated set of disciplines capable of performing the
most challenging of remote inspection and intervention techniques with precise
