Van Oord First to Adopt the New Tritech Gemini
17 March 2016
Dutch contracting company, Van Oord Dredging and Marine Contractors B.V. [Van Oord], have purchased a suite of Gemini 720is multibeam imaging sonars, in the week of its launch at Oceanology 2016, 15 - 17 March, ExCel, London.
The Gemini 720is sonars, combined with customised Gemini SeaTec software, will enable Van Oord to automate basic tasks such as monitoring the touchdown point of pipelaying operations on Stingray, the shallow-water pipelay barge; thus eradicating the need to deploy a highly-skilled operator and reducing the overall project time and costs. The system will also be used for obstacle avoidance on rock dump vessels. Van Oord’s initial trials of the Gemini system during survey inspections verified its scope, prompting them to purchase.
With real-time visualisation and a fast
update rate of 30 Hz across a 120 degree field-of-view, the new Gemini 720is
regenerates in a new body shape with the latest electronics and features an
integrated velocity of sound sensor and near-range focus. Communication
protocols are Ethernet communications as standard (VDSL and dual communication
units are also available) and the standalone Gemini software offers basic
target tracking capabilities, including SeeByte advanced target tracking.
Vanessa Venida, Chief Surveyor, commented: "We tested the Gemini 720id to discover that the 20 degree vertical beam provided us with the best overall performance for the dredging, marine engineering and energy projects we undertake. At Van Oord we have seen the true benefit in moving to multibeam technology for imaging sonars and due to the improved performance and the enhanced software capabilities of the new model, we are adopting the Gemini 720is as our standard for our offshore operations.”
Scott McLay, Tritech Sales Director, commented: "With the launch of the next generation of multibeam imaging sonar, the delivery of 6 Gemini 720is sonars to Van Oord along with Gemini SeaTec software specifically adapted to their requirements, highlights the market confidence in our multibeam technology and emphasises our ability to innovate existing provisions to improve customer operations.”
