Aker Solutions advanced H6 drilling rigs use integrated Milestone video
surveillance for state-of-the-art operational control in harsh environments
Aker Solutions is building model H-6e drilling rigs, the latest-generation of semi-submersible
platforms specially designed to conquer the challenges of deep water drilling operations in harsh
environments. They include the Aker Solutions MH DrillView™ system for optimal monitoring of
the operations in action, which has integrated Milestone XProtect® IP video surveillance software
at its core.
The latest model, the Aker H-6e, is one of the largest drilling rigs ever, constructed by Aker Solutions. Two
hulls were produced by Dubai World Drydocks and
towed to Aker Solutions' yard on the west coast of
Norway. There they were combined with locally
produced topsides and equipped with the integrated
Milestone XProtect video surveillance software, with
components delivered by Last Mile Communication AS.
For over thirty years Aker Solutions has been a market
leader in the design of drilling equipment and facilities,
recognized for its development of new technology for
deep water drilling based on field-proven equipment.
Satisfying the industry's requirements for efficiency,
safety and reliable operability has always been a prime
Harsh environments require reliable, robust solutions
The topsides of the Aker H-6e rigs weigh 16,000 tons and can drill in water depths down to 3,000 meters,
with a maximum drill string length of 10,000 meters. Drilling
operations are mainly conducted within enclosed areas of
the topside facilities for safe, year-round operations.
Exposed operating and inspection areas are shielded from
wind and water, and a variety of heating systems
compensate for Arctic weather conditions. The H-6e hulls
provide enhanced stability, so drilling can continue in
weather conditions that would require other rig designs to
shut down.
The MH DrillView system provides a user-friendly interface
for acquisition, logging, storage, distribution and display of
drilling data, as well as setup and remote control of drilling
equipment. MH DrillView integrates the drilling systems into
one common control and monitoring center for greater
efficiency, safety and ease of use. Real time drilling data can The MH DrillView with integrated Milestone XProtect
be shared between the driller, rig offices, shore base or other
locations accessible by telecommunications.

Integration in practice for local and remote
operations or diagnostics
Based on drilling operational experience, the
Aker H6 offers a completely integrated platform
designed for the entire drilling rig. User-friendly
screens cover all normal drilling operations, as
MH DrillView contains all the mechanisms
required to interface with drilling equipment.
Typical examples are control of pumps and
valves on mud system schematics, hydraulic
power units, and so forth. Users can monitor the
status of the individual drilling equipment for
efficient troubleshooting or maintenance
Information is easily accessible due to the
system’s versatility and flexibility. Operators can
set up trend charts from a large selection of direct
and computed variables. All data stored from
previous wells can be replayed for analysis and is available for offline reports. The drilling data is stored in
an SQL real time database.

chairs with joysticks and viewing displays
The MH DrillView system has a built-in web server, which means that all data can be made instantly
available on a local area networks (LAN), wide area networks (WAN) and the Internet. The drilling stations
offshore can be linked via the Internet to the remote diagnostics center at Aker Solutions, so
troubleshooting can be carried out in cooperation with customer service without requiring Aker Solutions
personnel to travel.
Built-in drilling rig surveillance system
Safe operation of an automated drilling system requires effective
monitoring in very demanding environments. Aker Solutions install up to
90 or more video cameras on each rig, and make the outdoor camera
housings specially designed and certified for handling harsh demands.
The ATEX approved (explosion proof) stainless steel enclosures are
IP66 and are specially designed for hazardous location installation. The
dome type pan-tilt-zoom (PTZ) camera used is very small, weighing less
than 12 kilos with a standard wall bracket and sunshield: the entire unit
is only 155 mm in diameter and 300 mm high, and can therefore be
placed in very small areas inside the hull of the drilling rigs. The pan-tiltzoom camera movement is very fast at 100° per second, with endless panning, no stop and return. The
MH DrillView system can also be delivered with fixed cameras, with or without zoom.
To keep the lens view clear from water, the dome glass can be cleaned using a high pressure wash unit.
Drying is done by compressed air. Like all outdoor dome cameras, the housing has a fan and thermostatcontrolled heater inside that keep them from fogging or icing up.
Milestone XProtect IP video software supports mix of hardware models
The MH Dome CCTV system is interfaced to Milestone XProtect® Enterprise software, which has been

tailored by Milestone consultants to the Aker Solutions system use requirements. The Milestone XProtect
software provides powerful video management and control functions and can easily be made accessible to
remote users over the Internet or company Intranet.
The surveillance hardware includes a dome camera from Panasonic, model WV-NS202. Other network
cameras used are Panasonic WV-NP1004 and ACTi ACM-1430. On drilling equipment where close-up
images are required, “the world’s smallest ATEX approved camera” (analog) from Orlaco is used. For
converting analog signals to IP, ACTi SED-2610 or 2120 video servers are used.
The MH DrillView systems with integrated Milestone XProtect IP video management software have been
delivered to such customers as Maersk, Seadrill and Aker Drilling.
