International Submarine Engineering Ltd is pleased to announce the award of a contract to supply and operate two Explorer Autonomous Underwater Vehicles (AUVs) to Natural Resources Canada (NRCan).
The AUVs are designed to be used under the ice in the Lincoln Sea, supporting Canada's seabed survey program in 2010 and 2011 under Article 76 of the United Nations Convention on the Law of the Sea (UNCLOS).

NRCan requirements call for a payload configuration consisting of both single and multibeam echosounders, and an inertial navigation system with external acoustic homing.
The 6.0 meter long hull configuration will also allow for the installation of a 48.75 kWh Lithium-ion battery pack, providing an endurance of 85 hours. The Explorer vehicle design is modular - all major sub-systems including control electronics and batteries can be accessed and maintained in the field.

ACE is designed to provide the capability to create complex, high performance, reconfigurable real-time control systems using a library of control components.
A key requirement of the UNCLOS program is to conduct a schedule-sensitive development program that will validate the navigation and support procedures used during surveys. The program involves underwater vehicle operations in open waters of Newfoundland and frozen waters of Northern Canada. It will involve the use of Memorial University of Newfoundland's ISE built Explorer 3000 meter AUV and AUV operating team for developmental trials.
Additionally, ISE's involvement in the early 90's with its Theseus AUV performing cable-laying under the ice and subsequent arctic survey experience will lend additional expertise to the program.
