Enhancing Safety Measures for Ships during Volcanic Activity

Analyzing the hazards posed by volcanic activity to maritime shipping, this presentation explores the various risks such as physical damage, loss of stability, and impacts on instruments and engines. It discusses sources of information available, including Volcanic Ash Advisory Centers and Volcanic Observatory Notice to Aviation Portal, and suggests tailored messages for mariners. The talk proposes collaboration between meteorological and navigational authorities to develop standard warning texts specific to volcanic events, emphasizing the need for enhanced safety protocols and engagement with aviation and meteorological initiatives in the Southwest Pacific region.

Presentation Transcript

1. Volcanic Activity and MSI Volcanic Activity and MSI Hazards to shipping and sources of information Are there any gaps and can we do better? Presented by NAVAREA & METAREA XIV WMO, Geneva 12th 16thSeptember 2022

2. VOLCANIC ACTIVITY AND MSI 1. Is it a hazard to ships? https://volcanoes.usgs.gov/volcanic_ash/marine_transportation.html https://www.youtube.com/watch?v=6lmKUGj_5fc (Paul Cragg Start 15:13) Credit: USGS both images NAVAREA XIV, METAREA XIV & CAA NZ

3. VOLCANIC ACTIVITY AND MSI 1. Is it a hazard to ships? Volcanic Activity Pumice rafts Hazard to Ships Blocks seawater cooling systems, overheating engines Impact to instruments on the ship s hull. E.g. Echo sounders, speed logs Physical damage to, or destruction of ship Gas emissions (sub-sea) Explosive surtseyan (shallow water) eruption Pyroclastic flows (speeds of hundreds KM/h, temperatures hundreds of degrees C) Heat and impact damage, ship stability Loss of stability, navigational data, engines, abrasion/corrosion damage Loss of visibility Hazardous to people Potential corrosion Tephra (from ash to larger objects) Sulphur dioxide Hazardous to people Dependent on depth of water. Loss of stability, etc. Tsunami NAVAREA XIV, METAREA XIV & CAA NZ

4. VOLCANIC ACTIVITY AND MSI What sources of information are available? Volcanic Ash Advisory Centres (VAAC) NAVAREA XIV, METAREA XIV & CAA NZ

5. VOLCANIC ACTIVITY AND MSI Volcanic Observatory Notice to Aviation (VONA) Portal NAVAREA XIV, METAREA XIV & CAA NZ

6. VOLCANIC ACTIVITY AND MSI Tailored messages for Mariners? NAVAREA XIV, METAREA XIV & CAA NZ

7. VOLCANIC ACTIVITY AND MSI Tailored messages for Mariners? NAVAREA XIV, METAREA XIV & CAA NZ

8. VOLCANIC ACTIVITY AND MSI Next steps? Should we (MET/NAV) collaborate on this? Discuss the benefits of developing standard navigational warning text, specific to volcanic activity? Consider the benefits of engaging in the aviation/meteorological work underway in the Southwest Pacific? Anything else? NAVAREA XIV, METAREA XIV & CAA NZ
