QPS Client Spotlight: Deep B.V.
Deep B.V., combining enthusiasm and expertise
Deep B.V. is a survey company based in Amsterdam, The Netherlands, offering specialized services in hydrography, geophysics and oceanography since 1999. Their areas of operation include inshore waterways, harbors, coastal zones and offshore areas.
Whether selecting personnel, purchasing equipment or software; capability of delivering reliable data lies at the core of Deep’s decisions. They use the very latest in survey techniques to offer high end customer specific solutions. Deep has been using QINSy to meet these needs since 2001 and became a Fledermaus client in 2010. Recently, they were selected by QPS to beta-test the latest addition to the QPS software family, Qimera, in order to experience the capabilities of the total QPS workflow, from acquisition to visualization.
A Deep B.V. surveyor states:
“As an all-round surveyor, QINSy enables me to combine a wide range of survey techniques, and makes it possible to create out-of-the box customized solutions. A project I’ll always remember was the positioning of seven vessels during a cable beaching. The operation was very intense and complex. But I could master it, using a single dongle.”
Deep has contributed to many large projects including:
- Offshore energy wind farms in the Netherlands: using multibeam (bathymetric and backscatter), sidescan sonar, subbottom profiler, magnetometer and multi-channel sparker
- Angola wreck and debris removal: multibeam (bathymetric), sidescan sonar and magnetometer
- Poti Georgia Breakwater Survey: combination with Skeye dual head tilted multibeam, photogrammetric survey
- Luchterduinen: Trencher mounted dual head multibeam, USBL, DVL, INS, video, vessel mounted multibeam
Figure 1 shows the Caritas I SS shipwreck, which sank due to a collision in 1947. The data was acquired by Storm survey vessel which is equipped with R2Sonic 2024 and uses QINSy for data acquisition.

Figure 2 and 3 are related to Borssele wind farm, where the geophysical site investigation survey was conducted by Deep B.V., using two vessels. Deep B.V. conducted high resolution bathymetry, side scan sonar, magnetometer and seismic profiling surveys for the Dutch Enterprise Agency (RVO).

Hook-Up Operations added to QINSy
QPS has released a new feature with its latest QINSy version 8.10.2015.06.29.1, called “Hook-Up Operations for Anchor Handling”, for pre-laid anchors powered by Orcaflex of Orcina.
Traditional anchor handling, including showing the catenary, was already possible with QINSy. The anchors are run from the rig or barge using tug boats that deploy the anchors at the planned positions. During the anchor handling procedure the catenary, powered by Orcaflex, is shown during the entire operation.
With the new Hook-Up procedure the anchors are already pre-laid on the seabed, but not yet connected to a rig or tug boat. The anchor has a wire with a (sub) surface buoy at the end.
A tug boat will pick up this buoy and connects its own working wire to the anchor wire. After that, it will sail back to the rig where the anchor wire will be connected with the rig chain wire coming from the fairlead winch.
After completion of such an operation the result will be the same as with normal anchor handling: A rig is connected to several dropped anchors in order to stay in its place.
The advantage of using Orcaflex for the catenary calculation is that it supports complex anchor wires that consist of different types of material, which all have their own structural characteristics.
The Hook-Up functionality is added in the Session Setup of the QINSy Controller, were the Hook-Up operation is added as a new operation type.
The operation can be visualized in 3D using the QINSy 3D Display. The catenary of the anchor chain and wires are displayed as well as the distances between the seabed and the deepest point of the catenary and between subsea assets and the catenary.
QPS welcomes Ms. Samantha Bruce and Ms. Victoria Price to our USA office
We are pleased to announce the addition of two highly skilled Technical Sales Engineers, Ms. Samantha Bruce and Ms. Victoria Price to the Portsmouth, USA office.
Samantha has joined the QPS team from the NOAA Integrated Ocean and Coastal Mapping Program where she worked as a Hydrographic Data Analyst focusing on Hurricane Sandy affected areas. Prior to being at the NOAA Joint Hydrographic Center, Samantha worked as a Geospatial Extension Specialist for the S.C. Sea Grant Consortium and was an adjunct faculty member of the Department of Geology and Environmental Geosciences at the College of Charleston. Samantha completed her undergraduate degree at Brevard College in Environmental Studies and Geology, and earned an M.S. at the College of Charleston in Environmental Studies with a focus on Water Resources.
Victoria previously worked at the University of New Hampshire’s Center for Coastal and Ocean Mapping as a research scientist, where she focused on developing new techniques for habitat classification using remotely sensed bathymetric data and object-based image analysis. She has a background in lidar and acoustic data processing and analysis for ecological purposes, as well as the collection and analysis of high-resolution imaging sonar data for fisheries ecology applications.
