Non-Destructive Rope Examination07/09/2009 |
| There are a plethora of wire ropes used on offshore construction vessels. The wires can be very long (several kilometres) and quite inaccessible. They are performing in a harsh environment in terms of being underwater or in corrosive weathers and atmospheres. High performance and integrity is demanded so that safe and efficient operations can be achieved. Thus the performance of the ropes is paramount and all aids to reliable and efficient inspection are very valuable to the industry. |

Magnetic rope testing (MRT), which measures changes in magnetic flux along the length of a wire rope and identifies the presence of anomalies in its structure, is a comparative process. To fully assess the condition of a wire rope, the operator of an instrument needs to know what to expect in terms of wire rope structure, fill factor and metallic cross section.
As there is little published guidance on MRT in the marine industry, the International Marine Contractors Association (IMCA) has risen to the challenge and published ‘Guidance on Non-Destructive Examination by Means of Magnetic Rope Testing' (IMCA SEL 023/ M 197).
The new document, with its useful full colour illustrations, aims to provide guidance on the use of non-destructive examination (NDE) by means of MRT for wire ropes, to assist with inspection and integrity management.

MCA on Surveying the British Coast |
Rob Spillard explains how the MCA is conducting hydrographic surveys, including the history of British hydrographic surveying, latest developments in technology and wreck research projects, sometimes accompanied by a BBC TV camera crew. This movie includes an example of the discovery of two sunken WWI submarines off the Orkney Islands.
