Mariner's Draft Survey

Features
Read full description

Mariner's Draft Survey is the draft survey and cargo planning app for bulk carrier officers. Built by a Chief Officer, it works from your own ship's tables and shows the working behind every figure, so you can check the calculation, not just trust it. DRAFT SURVEY • Six drafts, forward, midships and aft, port and starboard, on a ship diagram • Corrections to the perpendiculars, mean of means, trim, list and hog or sag • Hydrostatic interpolation from your vessel's own table • First and second trim corrections, and the dock water density correction • Ballast, fresh water, fuel and other deductibles from your sounding tables, with trim and list corrections • Net cargo by difference, with lightship and constant • Tap any figure for its formula and the numbers that went into it • A signed PDF report with your company's name and logo STOWAGE AND LOADING • Stowage Plan: share the cargo between the holds for the trim you want, loading or discharging, with a second cargo or on top of cargo already aboard • Sequence Plan: pours and ballast steps the terminal can work, with trim checked at every step • Manual Stowage: when the stow is already decided and you just want the sheet • Trimming Calculator and Grab Counter: the last tonnes for the final trim, counted grab by grab, with an ETA for each hold • Hatch by Hatch: a fair figure per hold when the shore figures don't add up to your survey CARGO VOYAGE PLANNER • How much she can lift, and which limit sets it • Every limit on the passage in one answer: load line zones and seasons, channel depths with your under-keel clearance, berth drafts and air draft under bridges • Load lines checked by displacement and at the mark amidships, using your certificate FWA • Fuel, water and endurance to every waypoint, with ECA and port rates • Enter the drafts and figures measured at any port, and the rest of the voyage is worked from them • A passage plan report to print or share AT THE SHIP'S SIDE • Draft Reader: read the marks off a photo when you can't read them by eye • Heel Meter: work out the seaside draft you can't read from the heel and the side you can • Ballast Watch: live pumping progress from your soundings, with finish times and alarms • Conditions: drafts in new water, and the most she may load in any zone YOUR VESSEL, YOUR DATA • Import hydrostatic and tank tables from Excel or CSV, and keep a profile for each ship • Each ship keeps her own survey and plans; history is listed by vessel • Back up everything to one file, and restore it on a new phone • No account, no sign-up, no ads and no tracking. Works fully offline, and nothing leaves your phone. A full user manual is built in, and at marinershandapp.com/draftsurvey. Planning tools are an aid to the officer's own calculation and judgement: check every figure before loading.
