We are looking for a person who has a good sense of order and is used to working both independently and in groups.
In addition to the technical staff hired consultants, students and researchers will work with the AUV. It is therefore important to have a good ability to cooperate and a good ability to communicate in writing and orally. Communication languages are English and Swedish. If the candidate does not speak Swedish at the time of employment, the university provides language training with the aim of being able to communicate in Swedish within 2 years.
The person we are looking for must have relevant technical education, corresponding to at least 4 years of technical high school (or equivalent) and documented practical experience of
* AUV operations at sea
* AUV maintenance work
* Basic mechanical and electronic integration of sensors on an AUV
* Underwater navigation and communication, including challenges in precision, propagation of errors and uncertainties as well as improvement of positioning and underwater communication equivalent to the system available on GU's AUV (Honeywell HG9900 IMU with Nortek 500 kHz DVL and USBL positioning). Feel free to describe the challenges you encountered and how you solved them.
* Mobilization and demobilization of AUV or equivalent equipment on ships, and transport
* Operating and basic troubleshooting of the acoustic sensors (Kongsberg EM2040 MBES and Edgetech 2205 SideScanSonar / SubBottomProfiler) that GUs AUV is equipped with
Describe the practical experience substantiated by references. Relevant references may be contacted.
* Documented practical experience of operations with a Hugin AUV
* Experience of more advanced development work and / or quality work with a Hugin AUV (or equivalent AUV)
* More advanced development and quality work with underwater navigation
* Detailed knowledge of one or more of the sensors that the University of Gothenburg's AUV is equipped with
* Broader experience of mobilizing major infrastructure on ships
* Higher education in electronics, IT, underwater technology or similar relevant subject
The ice-covered parts of the oceans have a key function for the climate and future sea levels. Due to technical challenges in these remote and inaccessible areas, very little is known about these systems and their future changes. The only way to systematically map the processes under the floating ice is with autonomous underwater vehicles (AUV), equipped with specialized sensors and capacity for advanced obstacle avoidance and ability to perform long missions without contact with the surface vessel. In a new staking, University of Gothenburg will carry out previously impossible measurements under some of the most difficult-to-access areas on Earth: the floating glaciers around Antarctica and Greenland. We will use an AUV with capacity to navigate under the ice to map the seabed and the ice thickness, structure, and presence of meltwater channels.
To implement this long-term investment, the University of Gothenburg wishes to expand its technical support operations by employing an AUV technician. You will work in a small but knowledgeable team consisting of 1-3 researchers, 1 ship technician, 1 computer technician, technical consultants and grad students specializing in autonomous underwater vehicles and their applications for the polar oceans. The university is in need of qualified technical staff who can perform service and maintenance, assist with handling and basic installations and repairs of the university's AUV (a Kongsberg Hugin AUV, see https://www.gu.se/en/skagerak/auv-autonomous -underwater-vehicle). It is also possible to participate in longer expeditions at sea, including to Antarctica and Greenland, but this is not a requirement.
The AUV owned by the University of Gothenburg:
The University of Gothenburg's AUV is a Kongsberg model Hugin, manufactured in 2018. It has 3000 m depth rating, is 6.5 m long and weighs about 2 tonnes. It is equipped with a Honeywell HG9900 inertial navigation system that uses two Nortek DVL for navigation and state-of-the-art acoustic sensors such as an EM2040 multi-beam sonar, an Edgetech Side Scan Sonar, and an Edgetech Sub Bottom Profiler. Other sensors include dual SeaBird 19+ CTD with SBE43 oxygen sensors, water sampler, low frequency ADCP (RDI Pinnacle 45 kHz) mounted looking upward, a DeepSUNA nitrate sensor and a Contros CO2 sensor. More information about AUV can be found at https://www.gu.se/en/skagerak/auv-autonomous-underwater-vehicle.
The AUV is used for various research projects in offshore environments, including polar regions. It is operated from different platforms such as GU's
research vessel RV Skagerak (https://www.gu.se/en/skagerak) and research icebreakers from different countries. Larger research missions are normally planned at least 6-12 months in advance. When the AUV is not occupied with research it can be rented out commercially. Between assignments, the AUV is stored in a facility where it is possible to carry out basic repairs and upgrades.
The University of Gothenburg currently has an agreement with an external partner for operation, maintenance, storage and technical support during expeditions for the AUV. The technician we employ will work together with the hired technical consultants, and will be involved in any changes to the agreement and future procurements of technical support that are necessary for the operations.
Experience of ROV operations.
The work will consist of operation and maintenance of the AUV and its sensors, including:
* Basic repairs needed during field work or in connection with service
* Periodic maintenance according to the manufacturer's instructions (weekly, monthly and annual)
* Mechanical and electronic integration of new sensors including mounting, buoyancy adjustments, power supply and possible (serial) data transfer to payload processor (integrations are made in collaboration with the manufacturer)
* Future major upgrades that may need to be implemented
* Planning of mobilization and demobilization to research vessels and other platforms from which it will be operated
* Shorter (<1 week) operations at sea in connection with projects or tests
* Participation in education about AUVs as research platforms that the University of Gothenburg conducts
* Keeping of spare parts (including keeping track and ordering new spares when needed) as well as ordering and handling shipping of the equipment. As administrative support for spare parts and freight handling, the University of Gothenburg uses the Marine Facilities planning tool (https://www.marinefacilitiesplanning.com/about).
It is possible to combine the job with work at sea on longer expeditions (up to 2 months) but this is not a requirement.
