As part of its aim to promote hydrography and to create opportunities to exchange experience and knowledge between its members and others who are interested, the Hydrographic Society Benelux (HSB) organizes regularly (6-7 times/year) workshops on topics of interest for its members.
The Offshore Energy exhibition, together with the parallel conferences, is of interest to hydrographic surveyors and to those working in the related industries and government organizations. Offshore Energy 2019, therefore, offers a great opportunity to combine a visit to the exhibition/conference and to attend a workshop (14:00-17:00 hours) of the HSB.
The exhibition opens at 09:30 thereby offering time to visit the exhibition in the morning hours and during lunch break.
The HSB emphasizes that non-members of HSB are also heartily welcome!
The workshop will be held at the RAI – exhibition premises Amtrium-complex “Side events”. All presentations will be in the English language.
To attend this workshop, please register via the Offshore Energy 2019-website: https://registration.offshore-energy.biz and register as visitor to be able to come on the exhibition floor. For logistic reasons registering to be done before 6th of October 2019. Attendance of the workshop is free. There is a maximum of 100 attendees. “Walk-in registrations” pending on availability of seats.
On behalf of the Hydrographic Society Benelux I look forward to meeting you all on the 8th of October 2019.

Chairman of Hydrographic Society Benelux

1. Challenges with Acoustic positioning in shallow water, by Jan Erik Faugstadmo, Product-line manager Kongsberg Maritime Subsea Division
Operating acoustic positioning systems in shallow water introduces different challenges than operating in deep water and therefore must be addressed differently. The behaviour of the present-day acoustic wide band signals in shallow water conditions is discussed. Another topic is what kind of accuracies we can expect: this depends on the impact of errors from acoustic signal propagation, lever arms and ancillary sensors on the total propagated error in the final positioning solution. Selecting the appropriate equipment and using it in the best suited way will ensure a good operation.
2. Lay vessel ROV subsea positioning during pipeline touchdown monitoring, by Michiel van de Munt, who is in charge of the Allseas survey department.
For many offshore pipeline installation jobs in the more challenging terrains, (partial) ROV monitoring of the pipeline touchdown point at the seabed is a requirement. This activity is often performed from ROV support vessels, especially in deeper water. Thanks to the improvements in technology last decade, including but not limited to improved subsea positioning and extended ROV tether lengths, part of this work can be performed with ROV’s deployed from the installation vessel. The basic methodology, including calibration & position verification, as well as the challenges are addressed in a short presentation.
16:05 – 17:05 Workshop part 2
3. QuickVision: Ways to cost efficient subsea positioning, by Mr. Robert Andersson, Technical Product Manager in the Vision Innovation Program at the Fugro Innovation Engine in Europe and Alexander Steele who supports the worldwide program for implementing the effective deployment and use of new systems within Fugro’s Vision Technology Group.
Fugro QuickVision technology delivers a solution for efficient, accurate and reduced risk survey and positioning of subsea assets while increasing uptime and reducing operating costs. Through the use of coded targets and augmented reality tools, Fugro’s technology has been used to successfully install structures in multiple regions across the globe. In this session, a description of a recent project case study shall be presented alongside a demonstration of the QuickVision technology.
4. Navigating with Nortek’s DVL, by Brook Rodger. Brook is the Offshore Energy and Navigation Business Development manager for Nortek Group, having been with the organization since beginning of March 2019. Before that Brook was with iXblue as a regional Manager for Offshore Construction, Hydrography and Marine Navigation markets.
Topic is “Little man Syndrome”: The presentation will discuss how Nortek DVL’s have enabled navigation in more vehicles, platforms and locations than before.
