Imenco’s ROV Shackle
Imenco's semi-automat-
ic ROV Shackle has been
proven as the safest and
the best in the market
because there is no need
to retrieve the shackle pin.
The shackle can be used
as many times you like as
long as you clean it with fresh water after operation. No
loss object occurs and no prevention is needed, and easy
handling, operated with only one manipulator claw, and
with safety lock. Maintenance kit available upon request
to save time if maintenance should be needed. Many
major operators and contractors have recommended
Imenco shackle for safe and user friendly operations
underwater. The shackle's body and most part is made
from high tensile stainless steel S165M equivalent to
Martensitic Stainless steel 17/4PH The pin is standard
shackle pin. The Imenco Shackle comes in various sizes
6.5T – 12T – 17T – 25T- 25T- 35T – 55T – 85T –
150Tons. Safety factor is 5. Any certification can be pro-
vided according to client's instruction.
For the bigger shackles clients often request a trans-
portation basket which also can be certified.

Fugro GRL Models NDT Tools
As part of a European FP7 Project to develop new
underwater non-destructive testing tools, Fugro GRL
provided its DeepWorks software to simulate the deploy-
ment by ROV of a long range ultrasonic manipulator in
the jacket structure of an offshore platform. The work was
part of ‘SubCTest’, a 2m project, sponsored by the EC to
develop ROV deployable inspection systems.
TWI in Cambridge has developed a prototype Long
New Mooring Comms System
Traditionally, moorings have had to rely on the mobile telephone
network or radio to transmit data to onshore bases. Off the coast
of the islands of Morea, a new innovation provided by MacArtney
Underwater Technology Group transfers data via wireless modem.
This new technology opens up areas otherwise unavailable by
mobile networks and unsuitable for conventional radio transmis-
sion systems. In the drive to understand the mechanics and effects
of global warming on our planet, oceanographic institutes are
installing buoys in various areas to map the water conditions and
wildlife and to chart any changes over time that relate to an
increase in global temperatures. The sites of such buoys vary great-
ly and one of the more recent installations has taken place In the
coastal waters of the volcanic island of Morea, 15km North West
of Tahiti in French Polynesia. Chosen for its well-established coral
reef and its abundance of life, this location is expected to provide
valuable information about changes in a range of underwater
parameters, including water temperature, changes in current speed
and water levels. Yet placing moorings and designing buoys
requires expertise and cooperation between scientists, engineers
and underwater experts. Of the many considerations in designing
and building a mooring system is the communications system.
Information gathered from the range of instruments on the mooring needs to be transferred in some way onshore.
Typically, data from buoys is relayed to onshore information centres via mobile telephone networks, by radio trans-
fer or by cable. www.macartney.com
