LATEST TECHNOLOGY SHOWCASED IN 3 NEW CABLE TRENCHING MACHINES
With a history stretching back 20 years IHC Engineering Business has always led from the front in trenching technology. For the safe and reliable burial of subsea pipes and cable the offshore industry has made the company its first port of call. Three high-profile projects to be completed this year are reinforcing an enviable track record in subsea ploughs and tracked trenchers.
CABLE PLOUGHS
The Sea Stallion range of cable ploughs have buried in excess of 10,000km of cables throughout the world. In its latest form, due for delivery to the USA in November, the Sea Stallion 3, operating in 2,000m of water, can bury cables up to 150mm diameter to a trench depth of 3m. The new machine will trench in soil strengths from 5kPa up to strong clays of 350kPa.
Another brand new system, the all- new Advanced Cable Plough 2(ACP2) is the first in the offshore industry to be optimised for high performance in all areas but especially for the safe handling of large diameter power cables. This soon to be-completed machine is unique in its ability to accommodate products up to 300mm diameter with a minimum bend radius of 5m and to offer both simultaneous lay and trench and post lay trenching (seabed cable loading). An interesting feature to assist in
shore approaches is the addition of an anti-cavitation jetting system. ACP2 is designed to DeepOcean’s specification and is destined for their state of the art power cable installation vessel Maersk Connector.
WINDFARM CABLE TRENCHING
The all-new Hi-Traq is the world’s first subsea trencher specifically designed for the installation and burial of wind-farm power cables. The notoriously harsh shallow water environments, typical of windfarms on the European continental shelf, present a special set of challenges for installation contractors. Hi-Traq, with its unique four-track chassis, is designed to provide enhanced steering and traction performance in the toughest subsea environments.
The ability to operate from a range of vessels, its extended weather window and high sea-state launch and recovery capability all combine to reduce project risk, time and cost. Hi-Traq is currently undergoing final assembly in readiness for testing and full operation early in 2017.
