Dive Planning

Dive Planning:

This page is intended to be a “one-stop-shop” for all upcoming DOD’s (Diving Officer of the Day). 

It contains all the information required to assist in planning a dive.

The information below may be aimed at the DOD’s but is opened for all to see and learn from.

Please check the DOD Roster to see when you are down as DO.  If you cannot make your allotted day please advise the Diving Officer who can assist in finding an alternative DOD.

The DO will contact you a week in advance of your allotted day to remind you.

If you would like to try being DOD, contact the Diving Officer.

Contact details for anyone in the club can be found on the clubs Teamer page.


Advance Planning:

In the week building up to the dive the DOD should be checking weather forecasts and tides to assist in selecting a suitable dive site.  Planned depth and dive profile may also need to be considered in selecting a dive site.

Information of some of the usual club haunts can be found on the dive sites page on the club website.  – This page is currently under construction –

The DOD should contact both the Tower and Assistant Tower nominated on the calendar to ensure that they are available on the day.

Useful links for dive planning can be found below:

The diving officer is available to assist in selecting a dive site.


Pre-Dive Planning:

Once a suitable venue and dive site has been chosen the DOD moves into the Pre-dive planning stage.  This generally takes place 1-2 days before the actual dive day.


Once a venue has been decided upon the club members must be notified. Under normal circumstances Teamer will be used.

The teamer message should be sent as early as possible to best allow members to organize themselves and their gear in order to make the dive.



The DOD should keep a close eye on the weather forecast in the build up to the dive.


Any club equipment required should be checked.  The equipment officers should be contacted to ensure that all equipment needed is ready and available for use.


The DOD should again contact the tower to ensure all is going according to plan.

If a second tower is required the DOD should organize somebody to tow and an assistant.  There are a limited number of people in the club with vehicles capable of towing the larger boats.  Contact the DO if you need help with this.


The DOD should ensure that there is sufficient Oxygen and Oxygen kits on the dive site.  They may bring the O2 themselves or delegate to a capable other.  Any O2 cells brought to a dive site should be sealed/unopened.

Emergency Plan:        


The DOD should familiarize themselves with the emergency plan for the chosen dive site.

The emergency plans can be found on the relevant dive site section of the club website. – This page is currently under construction –

The emergency plan for the site should contain at minimum Local emergency services; doctor; Gardai, hospital, recompression facility, helicopter, lifeboat, coast radio station, nearest telephone.



On the Day:

Upon arrival on the dive site the DOD becomes the site manager who does not necessarily do everything but ensures that it is done, and uses delegation where possible.

The matters to be considered are:


Assistant DOD:         

The Assistant DOD helps the DOD throughout the day.  They are especially important whilst the DOD is in the water.  They should be familiar with the emergency plans for the site.


Suitably qualified coxswains much be appointed to each boat.  They are responsible for their allotted boats throughout the day.  Assistant Coxswains should also be appointed.

Other People:

The dive site must be organized and run to minimized disruption to other people.  A lot of the slips we use are working slips and should be kept clear and clean at all times.

Emergency vehicle:           

A suitable emergency vehicle should be appointed.

Entry/Exit points:       

If a shore dive is to take place suitable entry and exit points should be selected.

Dive Groups:

Dive groups should be decided upon.  They should be split into boats if a boat dive is to take place.

Shore Marshal:

A shore marshal should be appointed. 

The Dive Brief:

The dive brief should be given to all parties present on the day, including Coxswains and Shore Marshal.  The dive brief should include the following points:

  • Feeling O.K.
  • Outline dive plan, direction of movement, maximum depth, time.
  • Order of entry/exit into the water.
  • Check hand signals.
  • If on exercise or training, explain the sequence of events.
