EGS Conducts Cable Route Survey between Orkney Islands and Caithness

EGS Conducts Cable Route Survey between Orkney Islands and Caithness

During April 2012 EGS (International) Ltd were contracted to carry out a pre-installation cable route survey between the Orkney Islands and the Scottish north coast at Caithness.

The scope of work involved a geophysical survey of a 70km long 560m wide cable route corridor, a geotechnical survey along the route comprising cone penetration tests (CPTs), and vibrocores, and an environmental survey comprising grab sampling and seabed imagery.

During the survey, MBES data was acquired using the vessel‘s hull mounted Reson 7125 system. In order to reduce the number of separately towed sensors, a combined SSS, SBP and magnetometer solution was used.

Upon completion of the geophysical operations the MV Neptune returned to port to re-configure for geotechnical operations. A total of 35 CPT and 35 vibrocore locations were identified. These were alternatively spaced at approximately 1km interval along the proposed main cable route.

EGSi have chartered the MV Neptune on two projects during Q1 and Q2 of 2012. Throughout both projects, the vessel provided a very reliable and efficient working platform with no down time attributable to the vessel on either project. Having a chartered vessel which is equipped with the latest specification of positioning and multibeam systems, this vastly reduced the installation and calibration times for both projects. Feedback from EGSi personnel on board was always positive, with all members of the vessel‘s crew being very helpful and pro-active. The MV Neptune also delivered a high standard of accommodation and victualing which also greatly enhanced the crews experience on board.

EEMUA subsea engineering course: materials selection and corrosion control

This two and a half day training course is recommended for both discipline and project focused engineers from a variety of backgrounds who want to gain an understanding of the fundamental principles for selecting and specifying materials of construction for subsea equipment, and for corrosion control during deployment, commission and operation. The course is based on the EEMUA User Guide to subsea materials selection and corrosion control, EEMUA Publication 194.

It is operated in association with the Society for Underwater Technology (SUT). Permanent employees of EEMUA and SUT member companies are entitled to a 20% discount off the standard course fee.
