Search the D&D KM-IT
The hotline allows the decommissioning and dismantlement community to post problems
in a specific decommissioning and dismantlement (D&D) area and get solutions
from the subject matter specialists. Users can also search for previously published
problems and their solutions.
Technology provides information on decommissioning and dismantlement related technologies including robotics
and any associated demonstrations. It provides technology descriptions, benefits,
limitations, and associated links and documents. It also provides vendor information,
technology and demonstration fact sheet reports, and search capabilities.
The custom decommissioning and dismantlement web crawler searches and retrieve information
from decommissioning and dismantlement related websites. The crawler provides the
user with a listing of best-matching web pages, usually with a short summary containing
the document's title or parts of the text.
The mobile system component provides access to important D&D KM-IT features through wireless devices. The D&D community users can access the following modules from their mobile devices: vendor directory, specialist directory, hotline, technology information, picture library, lessons learned and best practices, and the fixative module.
Lessons learned provides a repository of documents published by the decommissioning
and dismantlement community users. This allows them to share their experience with
Best practices provides a repository of decommissioning and dismantlement best practices
documents that the user community can upload to the system.
The video/picture library allows community users to upload decommissioning and dismantlement
technology and demonstration videos and pictures to the decommissioning and dismantlement
KM-IT system. The videos and pictures could then be viewed by the decommissioning
and dismantlement community.
Weekly reports published by the ALARA center include the status of the decommissioning
and dismantlement activities that have taken place at various centers. It includes
the list of ALARA center activities for consecutive weeks. This feature makes the
reports available to the entire decommissioning and dismantlement user community.
The specialist directory provides a directory of decommissioning and dismantlement
experts in different areas along with their contact information. The user can search
the specialist directory by name or by area of interest.
Vendor management provides a directory of decommissioning and dismantlement vendors
along with their contact information.
Collaboration tools provides information-sharing mechanisms such as decommissioning
and dismantlement news, events calendars, links, message boards, and frequently
asked questions (FAQs). This allows the decommissioning and dismantlement community
to interact with fellow users.
The training component provides training videos related to decommissioning and dismantlement
work, ALARA Centers’ training material and custom training for the decommissioning
and dismantlement community.

Autosub Long Range is a new type of AUV developed at the National Oceanography Centre (NOC) in Southampton, UK. By travelling slowly (0.4 metres per second), and keeping a tight rein on the power available to its sensors, it will be capable of missions of up to six months duration and ranges of 6,000 kilometres. It can dive to a depth of 6,000 metres. It is fitted with the latest oceanographic sensors, battery technology and advanced satellite communication. The sensors include dual 600 kHz Acoustic Doppler Current Profilers (ADCPs) which measure the water velocities above and below the submarine to a range of 50 metres; a microstructure turbulence probe used to measure small scale turbulence in the undisturbed water in front of the AUV; a fluorometer which provides information on the turbidity of the water; and a standard CTD (conductivity, temperature and pressure) sensor used to calculate water salinity and to identify different water masses. This comprehensive sensor suite will provide data about the mixing processes which occur around the shelf edge.

Historically, NOC have used Alkaline and Lithium Polymer battery packs in AUV's but with the ever-increasing deployment demands on endurance NOC required a fresh approach to power. Steatite worked with NOC to develop a mission-critical lithium primary solution that increased the AUV's endurance while reducing the whole life cost. AUV deployment can be costly with limited deployment and recovery times so deploying for as long as possible is essential.Steatite's lithium primary solution offered a number of benefits over the existing alkaline solution, such as greater endurance due to the increased energy density, weight saving, higher stable head voltage and a greater operating temperature range.Lithium batteries are already utilised with success in oceanographic applications including autonomous underwater vehicles (AUV), pipeline inspection, seismic surveying, acoustic profilers, sonar devices, oceanographic buoys, sensing devices, GPS systems and memory storage.Steatite Batteries designed and manufactured battery packs, each containing 56 lithium thionyl chloride D cells. These battery packs were then tested to meet UN Testing Criteria Part III 38.3 Rev 5, Clauses T1 - T5. The finished solution comprises of 10 battery packs in order to achieve NOC required battery set specification of 25.2V DC @ 152Ah. Each battery set will be constructed into a frame inside a pressure vessel by NOC with connections made to the Autosub. Operational Experience:
