15-12 RECORDS

RECORDS

This section covers the records required to be maintained during the conduct of a saturation dive.

Command Diving Log

An official diving log shall be maintained at all times throughout the dive. It shall contain a chronological record of the dive procedure in addition to any significant events. A narrative of significant events is to be recorded by the Diving Officer (or Diving Supervisor) and Saturation Diving Medical Officer (as necessary). This log shall be retained for 3 years.

Master Protocol

Each diving operation shall have a master protocol submitted by the Master Diver, reviewed by the Saturation Diving Medical Officer and Diving Officer, and approved by the Commanding Officer. This master protocol shall contain all the information needed to ensure that the dive follows a program consistent with the requirements for saturation diving as defined in this manual and shall include the necessary information to carry out these procedures on the specific operational platform.

A copy of the protocol shall be maintained as the master copy at the MCC. No alterations except those made by the Diving Officer and approved by the Commanding Officer are permitted. Any changes to this protocol shall be signed and dated.

Modifications

Because saturation dives generally follow a predictable pattern, only a few elements of protocol need to be modified from mission to mission. Consequently, once a complete and carefully written protocol is available, only minor modifications will be needed to support future missions.

Elements

The dive protocol shall include, but is not limited to, the following:

  • A detailed gas-usage plan, including projected gas supply requirements (paragraph 15-15). The required mixtures for supplying emergency, treatment, and excursion gas shall be specified for the depth ranges expected with specific depths to shift mixes indicated.
  • A compression schedule, including planned rate of travel with rest stops, if applicable.
  • Manning requirements, including a watchbill.
  • Predive and postdive procedures.

Chamber Atmosphere Data Sheet

Hourly readings of chamber pressure, temperature, humidity, oxygen, and carbon dioxide concentrations shall be recorded. In addition, time of operation of the carbon dioxide scrubbers and time of carbon dioxide absorbent replenishment shall be recorded.

Service Lock

The following information shall be recorded: date, depth, clock time upon leaving the surface or leaving the bottom, and items locked in or out of the chamber. This information is useful in controlling the spread of contaminants and in minimizing the combustibles in the chamber while in the fire zone.

Machinery Log/Gas Status Report

A record of the status of all gas banks, including their pressure and mixture, and of the status of all DDS gas delivery equipment, shall be maintained. This log shall be reviewed by each oncoming Diving Supervisor prior to assuming the watch and daily by the Diving Officer and Master Diver.

Operational Procedures (OPs)

Currently approved operational procedure sheets are to be properly completed and signed by the operator and then reviewed and signed by the Diving Supervisor and Dive Watch Officer and logged in the Command Smooth Log.

Emergency Procedures (EPs)

A set of approved emergency procedures with each individual watch station’s responsibilities shall be separately bound and available at the main control console throughout a saturation dive. The convenience of having emergency procedures on station does not relieve any diver or any saturation diving watch team member from being sufficiently knowledgeable, thoroughly trained, and fully qualified to react efficiently and instantaneously to any emergency. Constant training in these emergency procedures is necessary to maintain watchstanding proficiency.

Individual Dive Record

Use the Dive Reporting System (DRS) to record and report dives, as outlined in paragraph 5-9.
