Anchor Handling Tug Vessel
Jobs
Anchor Handling Tug vessels vary from offshore supply vessels (OSVs)
or platform supply vessels (PSVs) in being built-in with winches for anchor
handling and towing, with an open stern to permit the placing of anchors, and its
engine having more power to raise the bollard pull.
Anchor Handling Tug (AHT) vessels are primarily constructed
to handle anchors for oil rigs, derrick barges, pipelay barges, accommodation/constuction
barges etc, towing them to location, positioning them up and also act as as an Emergency Response and Rescue Vessel. They
are also utilized to carrying supplies to and from offshore units.
Although, Anchor
Handling Tug vessels are designed and build for anchor-handling and
towing operations, they can also carry out other jobs such as ROV (remotely
operated underwater vehicle) works, standby vessel for SAR operation, and perform
functions as supply vessel carrying cargo from shore to offshore rigs
/platforms/ships or barges etc.
The anchor handling operations are performed by
specifically designed machinery on Anchor
Handling Tugs. Anchor Handling Tugs
also have systems for rapid anchor release, which is handled from control
console on the bridge or other manned tower positioned in location in direct
communication with the bridge. The mention load used in the testing and design
of the towing winch is double the stationary bollard pull.
Anchor Handling Tugs are designed to encounter
the adverse conditions during sea rough and bad weather and can take on material
supply tasks similar to offshore supply vessels, there between shore bases and offshore
work locations. They also give towing support during tanker loading, towing of
threatening things and deep-water anchor handling.
