VERSION 1.0 1 Nautilus Dive Planner Pr oduct Ov er vie w view Product Over ervie 1.1 NAUTILUS DIVE PLANNER OVERVIEW Welcome to NAUTILUS Dive Planner Software. NAUTILUS is the new generation of Technical Dive Planning Software and the most comprehensive dive planning tool developed during the last few years. We are now 15 years into desktop dive decompression software products yet most of the products on the market are limited in their ability to deliver a wide variety of features and functions.
VERSION 1.0 1.2 NAUTILUS USER VERSIONS Nautilus Dive Planner Software comes in six versions. Each is a complete full working version of NAUTILUS but is limited in the maximum operating depth. These depth levels correspond with popular technical diving certification levels. We do not limit the purchase of any of the versions except for one. The licensee of one version will be able to purchase upgrades to the next depth version.
VERSION 1.0 Deco Stops Intervals 10-30 fsw in 1 foot increments Decompression / Bailout SAC rate Air Breaks: No Air Breaks Classic Air Breaks Custom Air Breaks Rule Reset: This resets all changes to the Preference Screen to the base defaults. Save: This saves the preferences set for use now and until it is reset.
VERSION 1.0 1.3.4 COMPARE 1.3.7 GAS MIXING This feature allows the user to compare, separate, and distinct profiles. This is an outstanding feature for looking at the time depth profiles, comparing OC to CCR, or for presentation and educational purposes. Complete calculator for mixing gas either from empty or partially full cylinders. Overlay Mode: - shows the dive profile graph on top of each other. Two Window Mode: - shows the dive profile graphs stacked one above the other.
VERSION 1.0 2 Nautilus Dive Planner Screen Descriptions 2.1 Opening Screen OPENING SCREEN The opening screen of NAUTILUS Dive Planner requires the user to read and either AGREE or DISAGREE with the terms and conditions of the use of the program. Nautilus keeps track of each time the program is launched. 10 When the user clicks the I AGREE, button then the program will allow full features and functions. Should the user click I DISAGREE, the program will exit.
VERSION 1.0 2.2 Preferences Units: Imperial or Metric (in sea water) Table Type: Stop Time or Run Time Scuba Type: Open or Closed Circuit and the associated SAC rates for those modes. If Closed Circuit mode is used, the Setpoint is to be indicated here. Air Breaks: Nautilus allows the user to have “classic” air breaks while breathing oxygen. When the decompression time on with a PO2. of 1.
VERSION 1.0 Conservatism Slider: increase decompression time over the base algorithm from 0-90 Deep Stops: Choose from No-Deep Stops, “Pyle Stops,” or Custom Rule Stops. Pyle Stops inserts a 2 minute stop 1/2 way between the maximum depth of the dive and the first required stop. Then, 1/2 way again between that stop and the required stop and then 1/2 way again until the required stop is reached. NAUTILUS credits at the shallow stops when it can for these deep stops.
VERSION 1.0 2.3 Gas Setup NAUTILUS Gas Setup screen is where the user creates the “Gas Portfolio” that will be available for creating profiles and tables. Here the user will select the gases that are expected to be used for a particular dive or that the user would like to have available while planning dives. There are 15 pre-defined gas mixtures that are commonly used for divers. There are also 14 additional “Custom Mix” placeholders available for creating additional mixes for the gas portfolio.
VERSION 1.0 2.4 Generate Profile Square Profile Illustrated in stop time. Generate Profile is the area where the user will plan the dive and generate the first set of decompression numbers. If this is the first time using NAUTILUS the Preferences and Gas Set-up need to have been visited before generating a profile. If, however, the Preferences and Gas Setup have been completed the user can start off at the Generate Profile tab. Examples shown with 18/50 trimix EAN 36% deco and 100% oxyygen 14 2.4.
VERSION 1.0 To perform the decompression calculations using All Available Gases that have been selected in the GAS SET UP, confirm that there is a 0 in the “Decompress to a Depth:” area and press DECO. NAUTILUS will calculate decompression and perform gas shifts are the appropriate levels based on the maximum PO2 selected in the PREFERENCES tab. A general Depth / Time schedule will appear to the right of the dive graph.
VERSION 1.0 CREATING PROFILES USING CLOSED CIRCUIT To create dive profiles where the diver will be using a closed circuit rebreather, the user needs to: ENTER THE CCR PROFILE Select the Generate Profile tab. Enter the Depth and Time and select the Setpoint gas in the pull-down to the right of the minutes box then press DIVE. 1. Enter the Preferences Tab and change the Scuba Type from Open Circuit to Closed Circuit. 2. Set the High Set Point and Low Set Point for the rebreather you are using.
VERSION 1.0 Square Profile CCR Heliox High-Setpoint Classic Deep Stops Gas Shift to Offboard Oxygen Classic Air Breaks (on CCR) Illustrated in stop time. NAUTILUS will allow the use of multiple off-board decompression gases and allow the user to create “what if” scenarios, illustrating bail outs with off-board gases as well. The user needs to set up a gas portfolio under the GAS SETUP tab to have access to those gases.
VERSION 1.0 2.4.4 REPETITIVE DIVES NAUTILUS creates repetitive dives with relative ease. After the user has set up Preferences and Gas Setup, return to the Generate Profile tab. Create the first dive as described earlier indicating depth and time and the bottom gas to be used. Then, complete the decompression. After the decompression is complete, enter the SURFACE interval in Hours and Minutes. For purposes of this illustration, select AIR as the surface interval gas.
VERSION 1.0 2.5 Manage Profiles NAUTILUS has a dive filing system that allows the user to SAVE each and every dive profile for future use. Each profile saved includes the actual profile, gas selections, and preferences. To load a dive, enter the Manage Profile tab, select a particular dive, and press LOAD. The dive will be loaded back into the Generate Profile tab where it can be viewed or modified. To save a profile press the SAVE button on the Generate Profile tab.
VERSION 1.0 2.6 Compare NAUTILUS features a unique COMPARE function screen that allows the user to select two dive profiles and compare them in two graphical forms. Overlay: In this mode, NAUTILUS will overlay two dive profiles. This view is helpful in visualizing the effects of time and depth of two dives on the decompression of each. This is helpful in identifying operational problems with a particular dive profile.
VERSION 1.0 2.7 TTable able Output NAUTILUS allows the user to output the generated dive profile in a variety of formats These formats are generaly refered to as Tables or Schedules. A Table is defined as a Schedule for a Single dive. NAUTILUS allows for a variety of table “formats.” In the Alpha Version there are four Table Formats available. Classic - This format follows that of the traditional US Navy type tables.

VERSION 1.0 3 Nautilus Dive Planner Decompression Models 3.1 NAUTILUS DIVE PLANNER DECOMPRESSON MODELS The Nautilus Dive Planner provides an interface into the following decompression algorithms: Parallel models: Hamilton-Kenyon 11 Compartment Parallel (TII-11F6) Buhlmann 16 Compartment Parallel (ZHL-16a) Hamilton-Kenyon Bubble Model Buhlman Bubble Model (VPM-X) US Navy 1965 (12-Compartment Parallel) 3.
VERSION 1.0 3.3 Hamilton-Kenyon Model 11 Compartment Parallel (TIIa-11F6) (aka DCAP) NAUTILUS Dive Planner is the only commercialy available decompression software product to liscense the HamiltonKenyon decompression model for use in generating decompression schedules for the technical diver. The “model” has been incorporated into some proprietary rebreather decompession computers, most notably the Cis Lunar and others to be available shortly. Some of Dr.
VERSION 1.0 eggs. The idea was to design a program that could be used by engineers and diving supervisors as well as researchers and would not need a programmer as such. This concept was accepted, and DCAP was developed and acquired by several major diving research laboratories. A project to develop deep air tables by one of the DCAP users, the Swedish Navy, led to a highly reliable matrix that later was found to work well for trimix diving also.
VERSION 1.0 NOAA Trimix Diving Tables, and the Andrea Doria OffShore Diving Tables. These tables have thousands of dives experience with very good results.. This is the model included in NAUTILUS. ‘Thus to wrap up, DCAP is a practical result of many years of collective experience in preparing and evaluating many types of decompression tables. The DCAP concept does not limit it to calculations with any specific model there is currently a choice of several models, and others are under development.
VERSION 1.0 3.6 Variable Permeability Model (VPM) Dr. David Yount created the Variable Permiablilty Model that takes into account the suspiscion that sub-clinical bubbling occurs on every dive of significant depth and/or time. The VPM-A, VPM-B, VPM-E and RGBM models were derived from this work initially done by Yount and are very popular with technical divers today.
VERSION 1.0 Comparison of the VPM to Conventional Decompression Procedures A major difference between the VPM and standard supersaturation algorithms is that the VPM programs use an iterative procedure to calculate a decompression schedule. In each step of the iteration, a new decompression schedule is calculated. The total decompression time is then fed-back into the calculation to revise the critical gradients (SUB PNEW in the BASIC Programs), and a more liberal schedule is produced.
VERSION 1.0 3.6 Future Models and Integration The goal of NAUTILUS Dive Planner is to be the single source tool for decompression planning for the advanced and technical diver. We will continue to seek out and work with the best minds in decompresison modeling and bring to NAUTILUS more reliable models as time progresses. We hope with time to incorporate some of the Navy Probability models including V-VAL and others.
