DiveSup

A dive supervisor console for Navy SCUBA and MK 16 rebreather operations. Plan, brief, check, run the side, and document a dive day from one screen.

Live web application

Built against U.S. Navy Diving Manual Rev 7 Chg A · For training and supervisor decision support

The Problem

Dive supervision still runs on paper

Checklists, wet notes, and table lookups compete for the supervisor's attention at the moment attention matters most.
Conditions checks are manual. Someone calls Port Ops, someone checks the weather page, nothing is logged.
Decompression math is done by hand under time pressure, including recomputes when a dive goes long or a stop is missed.
Casualty procedures live in a binder. Diagnosis flowcharts and neuro exams are hard to run cleanly from paper on a wet deck.
The paperwork burden lands after the dive, when details are already fading.

Supervisor signs on with name and contact number, nothing else to manage

The Capability

One guided workflow, plan through debrief

Mission library. Reusable dive plans with depth, bottom time, gas mode, and location. One tap to execute.
Guided dive day. Assign team, check conditions, brief and equipment checks, then the dive station.
Three sides of the house. SCUBA, MK 16 closed-circuit rebreather in nitrogen-oxygen and helium-oxygen, and a surface-supplied side covering air and mixed gas.
Doctrine under everything. Tables and procedures carry their source: Navy Diving Manual Rev 7 Chg A and published dive medicine references.

Workflow

Executing a plan starts the dive day

Step 1. Assign dive team: divers, standby, tenders.
Step 2. Conditions check against live sources.
Step 3. Dive brief and equipment checks.
Step 4. Dive station, the in-water watch screen.
The app enforces the order. Nothing in-water opens before the checks are done or the supervisor documents a bypass.

The workflow is stated up front when execution begins

Feature · Dive Planning

The plan computes its own limits

Mode first. SCUBA, MK 16 nitrogen-oxygen, or MK 16 helium-oxygen, each with its gas badges and its own table set behind it.
Live decompression verdict. Enter depth and bottom time; the plan banner answers immediately: no decompression required, setpoint, no-decompression limit, minutes remaining, with the Navy Diving Manual table cited as authority.
Oxygen flask endurance computed from charge pressure and air and water temperature, reserve excluded and assumptions stated.
Carbon dioxide canister duration by absorbent type, the limiting-factor input for the brief.
Repetitive dive support carries residual nitrogen forward into the next plan.

Feature · Dive Planning

Operating area on a real map

Dive site pinned on the chart, with maximum depth on the pin card.
Supervisor, date, local and Zulu time captured in the plan header; Zulu converts automatically.
Forecast and navigate actions sit on the map: pull the marine forecast for the pin, or hand the position to navigation.
The pin drives everything downstream: conditions checks run for this position, and the evacuation planner measures every chamber and hospital from it.

Feature · Evacuation Planning

The emergency action plan is a map, not a memo

104 facilities across the Indo-Pacific area of responsibility, chambers and hospitals, sorted by distance from the dive site pin.
Filters that match the decision: military or civilian, 24-hour, dive medicine capable.
Reach rings on the map: one-hour and six-hour rings by helicopter or surface transport, tied to the chamber-level requirement.
Chamber requirement computed from the dive profile per the manual's Table 15-4, shown as the level chip the plan must satisfy.
The plan form enforces doctrine: primary and secondary chamber and medical evacuation must be designated before every dive evolution, with the manual paragraph quoted on screen.

Feature · Conditions

Live go / no-go from real sources

Small craft advisory from the National Weather Service office for the operating area.
Lightning within 10 nautical miles from live strike networks, with the 30-minute hold rule cited.
Visibility and sea state from marine forecast feeds, checked against set minimums.
A no-go is a hard banner, and proceeding anyway requires a documented bypass that lands in the dive record.

Feature · Brief

A read-aloud brief that fills itself in

Dive data auto-populated from the plan: mode, setpoint, table and schedule, no-decompression limit from the app's own tables.
Environmental block filled from the live conditions check, including tide state and next low water.
Egress plan: duty recompression chamber and backup chamber for the operating area.
41 briefing items tracked so the supervisor knows what has been read and acknowledged.
Emergency procedures and line-pull signals are mode-aware: a rebreather brief covers rebreather casualties.

Feature · In-Water

The dive station thinks alongside the supervisor

Phase-aware diver timers. Descent rate, bottom time against plan, then ascent split into winch segments with stop clocks.
Live decompression recompute. If a planned no-decompression dive crosses its limit, the schedule and profile chart update in real time, with an exceptional exposure flag if the table runs out.
Scrubber tracking with a hard alarm below 10 percent canister life on MK 16 dives.
Omitted-decompression tool computes the return-to-depth plan and runs the recovery as a guided sub-card on the diver.
Rapid diagnosis engine for diving casualties, calibrated to published dive medicine references, plus a guided neurological exam.

Feature · Calculation Engines

Every mode carries its own math

SCUBA and surface-supplied air. No-decompression limits, repetitive groups, and residual nitrogen from the verified air tables; live in-water recompute when a dive runs long; ascent-delay handling and an omitted-decompression recovery planner, all per the manual's rules.
MK 16 nitrogen-oxygen and helium-oxygen. Manual-verbatim decompression and no-decompression tables, oxygen flask endurance from charge and temperature, carbon dioxide canister duration by absorbent, live scrubber countdown with a hard alarm, and battery voltage gates.
Surface-supplied helium-oxygen. A real decompression engine built from the manual's Table 12-4, plus the nitrox equivalent air depth grid with the manual's own conservative boundary, not a recomputed one.
Surface decompression using oxygen. In-water stops, surface interval, and chamber oxygen periods computed per profile.
Every mode. Live weather gating, tide state, and the required chamber level from Table 15-4 feed the same plan.

Feature · Surface-Supplied

The surface-supplied side, grounded in Chapter 8

Two gas modes. Surface-supplied air rides the same verified air tables as SCUBA and is not bound by the SCUBA depth limit. Surface-supplied helium-oxygen runs on its own Table 12-4 decompression engine.
Built under a hard grounding rule. The author is not surface-supplied qualified, so nothing was written from recall: every checklist, signal, and schedule traces to the Navy Diving Manual.
Verification you can audit. Table 12-4 was extracted from the manual by two independent methods and cross-checked; the cross-check caught real deep-schedule errors before release. Schedules that fail verification are withheld.
Rig-correct checklists. Loadout and pre-dive checks rebuilt from Chapter 8: rig, gas supply, umbilical, communications, and station, with dress-in, gas, comms, and entry procedures.
Correct comms doctrine. Voice is primary, line-pull signals per Table 8-2 as backup, and divers are individually tended, no cross-diver coupling.

Feature · Surface-Supplied

Running the side: station, gas, and the way home

Surface-supplied station card. The in-water screen swaps the rebreather panel for what this side actually watches: primary and secondary gas, emergency gas supply, umbilical status, communications state, and standby, with per-diver pneumofathometer depth entry.
Emergency gas supply calculator. The come-home bottle computed per the manual's formula and checked against the manual's own worked example.
Surface decompression using oxygen, end to end. In-water stops, the timed transfer window to the chamber, pressurization to 40 feet, and the oxygen periods, computed for air profiles and shown as a workflow card, not a paragraph.
Casualty procedures for this rig. Loss of gas, loss of communications, fouled umbilical, helmet or dress damage, and a falling diver, reachable from the station card.
The record keeps up. The dive record adds a surface-supply block: gas, decompression method, emergency gas supply, communications, tending, and depth source.

Feature · After the Dive

Debrief, casualty handoff, and records

Dive record PDF mirrors the manual's record sheets, including the MK 16 rig block: setpoint, diluent, absorbent, scrubber time.
Casualty handoff is button-first: status, treatments given, next intervention, concerns, with supervisor contact on the output.
Post-dive synopsis structures diagnosis, course of action, and further considerations, and auto-carries treatments already given.
End-of-operations message to the command duty officer carries the dive summary, including rebreather data.
Reference library on board: supervisor's guide, checklists, and a worldwide recompression chamber directory, searchable by country.

Supervised activity rolls up on the home dashboard

Feature · Generated Paperwork

The forms come out filled in

Sailing list, generated. Filled from the dive day's roster and operation data and produced server-side as a document.
Deliberate Risk Assessment, auto-drafted. The DD Form 2977 built from the dive plan's own data, then posted manually.
Dive record, mirrored from the manual. The record sheet layout follows the Navy Diving Manual's own forms, including the rebreather block, per-diver rig serials and gas pressures, and the surface-supply section.
End-of-operations message to the command duty officer generated from the completed dive, rebreather data included.

Feature · Menu Toolbox

Run Watches: a drill trainer built in

The menu carries four tools: Run Watches, Reference, Settings, and First-Time Setup for command information and team.
Run Watches is practice mode. A dry-run dive in real time: the supervisor tracks descent and ascent, jumps past dead waits, and drives every mark. Nothing writes to the logs.
A scripted casualty deck, graded level 1 through 4: caustic cocktail, rig malfunction with hypoxia, arterial gas embolism on fast ascent, trapped diver, lost diver, delays deeper than 50 feet on decompression dives.
Blind mode withholds the scenario, so the watch team has to diagnose from the symptoms, the way a real casualty presents.
Free-form mode simply runs watches on a planned profile for repetitions.

Feature · Menu Toolbox

Reference: the binder, searchable

Ten reference tabs: air and MK 16 no-decompression limits, shallow water, repetitive dive, ascent rules, line-pull signals, contacts, chamber directory, document library, and radio frequencies.
Tables are manual-verbatim with the source printed on the table: Navy Diving Manual Rev 7 Chg A, Table 9-7 and Chapter 15.
Standing emergency contacts preloaded: Divers Alert Network and the supervisor of diving mishap line.
Chamber directory: worldwide recompression chambers searchable by country, with a currency warning built into the header.
