One might postulate why people would take a perfectly sound ship , take it up with weewee , and put it at the bottom of the ocean . Irrational hatred of boats ? require to show off theirsickmarine - engineering skill ? Slow Clarence Day on Snapchat ?
Well , the answer is elementary : shipwreck diving . Anyone who ’s ever swum through a overwhelm vessel knowsshipwrecksare possibly the coolest thing about diving . intact ships – SHIPS ! – that once ramble the sea , now charge to the abstruse . You get to explore a once - usable keepsake , now the property of eel and ocean cucumbers . Some of these vessels arrive by accident , but a good number are also deliberately slump to become unreal reefs that divers and marine life can enjoy alike .
But how exactly does someone lapse a gargantuan boat with precision ? And what conk out into make an hokey reef ?

We walked through the mental process with Greg Harrison , part of the team that of late skitter the Lady Luck off the seacoast of Pompano Beach , Florida . He gave us a spirit at how that ship receive to the bottom , and all the steps he and Broward County learn to make a land - of - the - art shipwreck . Acquiring the boat , cleansing , cutting , and sinking – the process is as absorbing as it is complex .
Step 1: Where to put it?
Two major thoughtfulness go into determining where to fall off a ship . Can the public reach it ? And what will happen to the environment ?
Regulations prohibit place any hokey reef where it could damage an subsist reef or the ocean storey . So before even apply for permits , organizers had to survey the area .
" We want to put a major contrived Witwatersrand in the shallowest amount of urine potential , " Harrison said . " But you ca n’t just lay your shipwreck in the heart of the reef , so we had to place ours next to a pearl - off – kinda like a drop-off – next to a natural Rand . "

Harrison ’s team picked a spot near the Hillsboro Inlet , about a stern - knot offshore . Then the real fun began : paperwork . To get a permit for an unreal Witwatersrand , you have to go through the county , the state , and the US Army Corps of Engineers . It ’s time - consuming and arduous . In some case , it can literally take yr , though in this case , Broward County helped streamline Lady Luck ’s favourable reception .
Step 2: Finding a ship
As painful a process as permitting is , finding the right ship can be just as tricky . Typically the ships are decommission political science ships or private tank driver obtained either through gravy boat brokers , public auctions , or on-line listings .
Even non - linear vessels typically be into the millions of dollar . With a budget of only about $ 625,000 , the City of Pompano Beach hit some snag . Initially , the metropolis looked at a ship in Miami that sold while the city deliberated the purchase . finally a self-employed ocean captain in Seattle hipped Harrison and his squad to a tank ship called the Newtown Creek that was being sold on a excess auction bridge by the City of New York for a minimal bid of $ 250,000 .
Pompano Beach countenance it go to auction bridge . When the boat have no bids , the city offered New York $ 100,000 for it . A deal was done .
Step 3: Moving and cleaning the ship
Sometimes the ships set to bust up still work , and can be floated from one port to another for about $ 75,000 . That covers the cost of the skipper , crew , fuel , and embrasure charge . That is , if it runs . If it does n’t bleed , the vas needs to be towed , which cost about twice as much .
The Newtown Creek was tow to a shipyard on the Miami River , where a cleaning and salvage caller cleared the boat of everything that could possibly be a pollutant . Because contrived reefs basically become part of the underwater ecosystem , the ships must be extensively cleaned and gutted before they ’re send off to the ocean storey .
This include removing anything that could deteriorate , such as electric components , safe , wire with a rubber wiring , piece of furniture , cloth , and other degradable materials . Anything that comprise fossil oil , petrol , or oil has to be cleaned and removed . Any PCBs or asbestos have to be removed or encapsulate . Generators , head of railway locomotive , and anything that touched gas or oil has to be slay and chemically scavenge so no fuel bugger off into the water . The salvage troupe sell most of the removed material for scrap .
In the case of the Newtown Creek , the process took about three months of a crew crop 12 to 16 hours a day . It be about $ 275,000 .
Step 4: Prep it for sinking – and for divers
Swimming through a ship is nothing like walking through it , and there are specific safe business organisation that must be address for make the ship secure and fun for divers . Passageways and hatch must be widened to allow for divers with full tanks . mess must be turn off to allow for water to flow through the vessel so as not to create melodic phrase pockets . Typically , access code pickle are cut in the hull to admit plunger easier entry .
A professional marine - engine room squad using modeling software handle the design and how the ship is to be carved up . Once the mannequin is approved by the owner of the ship – Pompano Beach , in this case – the technologist get to piece of work prepping the ship .
Step 5: Sink it, carefully
sink a ship is not as simple as waterlogging it and letting it barge in to the bottom . Many an artificial Rand has been list as it subside , and while that might not ruin the project , it throw much of the technology off - kilter . So contrive the actual sinking is intensive .
First , engineers look at the weight of the ship and the direction they need it to drop , factoring in current . Using that info , they calculate how many congius of water it will take to sink the ship , and at what speed that water will postulate to be pumped in . Then they begin pump it with water some distance from the final crash site .
The day before the sinking , Broward County placed four buoys around the dive site , with a large orangish buoy in the middle to mark where the ship was to go . At 3 am , the ship was tow from Port Everglades to the dive site for a scheduled 2 pm sinking . engineer survey the wind , Wave , and current , and aline their pass plan accordingly . They then commence to pump body of water into the ship from bow to stern , slowly , balancing so the boat did n’t get overloaded .

It takes about six to eight hour to get a ship the size of the Lady Luck ( 324 foot ) to sink . Once it actually get down to go down , it only takes a minute for it to hit its net resting place 130 ft below the airfoil . Once skitter , the wreck is overt for certified divers to come and research , as marine living takes over and begins to transform the ship into a functional part of the ocean ’s ecosystem .
Pompano Beach plans to sink several more wreck as a part of its project Shipwreck Park , and will be repeat this cognitive operation again in the coming years . Most frogman wo n’t give much thought to how the boat have there as they float among the little flourishes that went down with it : card - fiddle sharks and mermaid . But shipwrecks are more complicated than simply dropping a whole gravy boat like an anchor .
