David Robinson, the Harbourmaster at Christmas Island, contacted ROV Innovations to complete inspections of their deep water moorings at Flying Fish Cove and the Smith Point refuelling facility. Working closely with commercial divers and engineers from Undersea Construction Ltd, we were able to inspect the deep water anchorages for the vessel moorings that were in 265m and 550m of water just off the Christmas Island coast.
With the commercial divers inspecting the top mooring components and horizontal spans, the ROV concentrated on penetrating the deeper water to inspect the chains, wires, shackles, dumpers, and anchors of the moorings themselves.
With additional modules on the Seamor ROV such as a Cygnus ultrasonic thickness probe, and Tritech underwater positioning system, additional information on the underwater assets was available including actual position of the anchor allowing the engineers to determine if the system had moved from its first position.
Thanks to David Robinson and Neil McNeil at Christmas Island for their great support and hospitality, as well as Wayne and Dave from Undersea Constructions Ltd.
ROV Innovations received an emergency call from Paul Pengilly, the Electrical Inspector at BHP Billitons Olympic Dam site at 19:30 Tuesday Night (12th May). ROV Innovations had a team on site in the remote South Australian mining site by Thursday Morning (14th May) ready to inspect one of the freshwater reservoirs that BHP were experiencing some issues with.
After completing the intensive inductions and safety requirements for BHP, the ROV Innovations team set to work completing a thorough inspection of the reservoir. Providing a live, high definition video feed for the BHP engineers, we were quickly and efficiently able to identify a few issues with the reservoir infrastructure.
Being a completely enclosed and covered system, the Seamor ROV showed itself to be the ROV of choice for these sorts of surveys. Having high torque thrusters to enable the ROV to access every point within the reservoir, powerful LED lighting to illuminate the zero light environment, and a high definition Sony camera, capable of zooming in of assets underwater without taking the reservoir offline, allowed the BHP engineers to have extreme confidence in what they were seeing, and how to rectify any issues with the least amount of impact to the reservoir operation.
On reviewing the operation, Paul had this to say about the exercise -
We did get very good images and these are now being reviewed by our engineers...
Having no one in the water also reduced the high risk hazard, and provided a zero risk and zero impact solution to the mine site.
Thanks to Michael and Simon Wright for their level of professionalism, Paul Pengilly at BHP, Darryl Hamlyn from Monadelphous Engineering, and all those who assisted in the extremely fast and efficient mobilisation to an extremely remote part of the country.
We look forward to assisting the guys out at Olympic Dam again in the near future!
