IALA Workshop On AtoN Services in Extremely Hot Climates

IALA Workshop On AtoN Services in Extremely Hot Climates

An IALA workshop on the subject of Aids to Navigation (AtoN) Services in Extremely Hot Climates was hosted by the Qatar Ministry of Transport and Communications, supported by Qatar Ports Company and Sealite in Doha, Qatar from 4 to 7 September 2016.

The workshop was attended by 44 delegates, representing 12 countries, 9 national members, 9 associate members, and 11 industrial members

The workshop was structured with presentations on relevant topics on day 1, with a technical study tour on day 2 (Picture) followed by working group sessions on day 3. Output work was reviewed and conclusions were agreed on the final day.

The workshop generated six conclusions.

  1. There is an increase in average global temperature, sea level and dust, giving rise to growing challenges in AtoN provision in relation to both equipment and personnel.
  2. There is a need for IALA guidance to identify appropriate standards for AtoN equipment for regions around the world in relation to issues such as temperature conditions; enclosure ratings; UV conditions; peak intensity specification for LED AtoN; batteries; optic service factor; thermal cap, etc. There are a number of sources of information on worldwide climatic conditions which can be referenced.
  3. Consideration of human factors in AtoN work in extremely hot and humid environments is essential, to ensure safety of personnel and productivity.
  4. Modular replacement is an effective maintenance strategy to minimise working on station in hot climates.
  5. Considering that manufacturer equipment tests are conducted at 25oC, there is a need to apply above average technical specifications for AtoN equipment in hot climates.
  6. AtoN competent authorities and service providers should work as closely as possible with suppliers and provide them with as much accurate information as possible.

The workshop further developed the draft IALA Guideline on Providing AtoN Services in Extremely Hot and Humid Climates. The output documents were forwarded to the ENG session for further development and completion.
