Need help with a tactical problem

[Schone23666]

So I am busy, or trying to be busy (LOL) writing fiction....and I have a segment where my designated "heroes" have to board and search a damaged vessel in a harbor, that's supposedly deserted (it's not) and is listing after suffering damage from an explosion in the boiler room area. The mission is to search the captain's quarters for any clues or manifest in regards to a high-value cargo that may still be down within the cargo interior hold of the ship.

The time is roughly late morning. It's the middle of winter though, and a heavy blizzard is blowing in, making visibility a problem. A fire had broken out earlier last night from the boiler room explosion, but has been put out by the local coast guard

Two sniper overwatch teams have been assigned and are monitoring the exterior of the ship from different, but not opposing angles. Helicopter gunship support is also standing by in case anything should go wrong and matters get EXTREMELY hairy. However, as stated visibility is a problem due to the snow. Let's just say this mission is in a more supernatural horror kind of vein.

But anyway....thoughts and opinions on how entering and searching the, or any sort of cargo ship should go about? My first impression is, well, mostly metal interior as opposed to a typical residential/office building, so ricochets from bullets and shrapnel might be a bigger problem, plus sound reverberation from any automatic weapons fire will probably be a bit more deafening on the ears. Having any sort of explosive or concussive device that creates overpressure in a ship's steel interior is gonna be real nasty too. And then there's the environment itself. All those narrow corridors and corners with sealed hatches that have to be accessed. Doors are always a problem in MOUT, but I'm thinking steel pressure hatches are a bit more challenge.

Oh, and just to add to it....the interior is barely lit as the power has gone out and only the ship's emergency lighting is on. And there are possible friendlies inside the ship as well....in the form of two police detectives who decided to board the ship first since it's under their jurisdiction, and there MAY be at least one if not several containers full of Russian mail-order "brides" that are meant to be sold off to slavers, but it's unknown if any of these women are still alive or if they've possibly frozen to death (or worse. This is a supernatural horror setting). There also happens to be several containers that are stacked full of WarPac weapons, that were also meant to be sold to an undisclosed buyer, but that's not quite the high-value cargo the heroes are looking for....

How does one deal with all this? Though I'm sure any naval special operations forces or boarding teams (SBS, SEALS, FAST, etc.) practice for situations involving the boarding and searching of ships fairly often. Any thoughts or suggestions?

The amount of damage you have described is pretty catastrophic.

If the ship is listing the boiler explosion has caused either a breech in the hull or popped enough welds to cause a major leak. It also means that the cargo hold has the potential to be partially flooded in order to cause the ship to list. An explosion that has caused that much damage is likely to have killed anyone in the hold and damaged or flooded any valuable cargo.

The fire is also an issue. Fires in ships are nasty and will have caused major toxic issues, also, I would be very surprised if the Coast Guard haven't formed a cordon and be crawling all over the ship to contain the fuel oil that is likely to be leaking from it. That means the harbour is full of HAZMAT boats and oil-spill cleaners are on the way.

Inside the ship, not only are the walls metal but the ship is listing so everything is canted at an angle. Below decks the corridors are coated with toxic soot and anyone not in BA is likely to suffer horrible effects. A boiler explosion that has caused a breech is also likely to have twisted ladders and steps up and down and caused some doors to be distorted and impossible to open.

I find it unlikely to think of any detectives being in the ship unless they're following a lead. Fire Investigators and HAZMAT personnel, yes, but local plods, no. The scene is a major environmental incident first and a crime scene second.

The heroes would be better off posing as a HAZMAT clean-up crew than a traditional SWAT breeching unit. I also don't see the point of a helicopter gunship back up, or the snipers: any incident will be inside rather than out.

My father was a fireman and worked in one of the largest docks in the UK (Port Talbot deep ore port: not much in transit but massive ships). If there had been an incident like that, crews would have been coming in from across the country and by the next day, international teams would be on the way.

This, of course may depend on the country it is set in, but a listing ship which has had a catastrophic explosion and fire is highly unlikely to be deserted the next morning.

I'd go for a high-tension infiltration with the heroes sneaking in wearing high vis and BA rather than tooled up for bear. In many ways this makes for a much scarier environment: the situation is dangerous and when the SHTF you don't even have the big guns to bail you out. This could be a really dramatic situation with lots of horror moments depending on the nature of your terror.

Thanks SimonMark6. A lot of really good points here. As you can probably guess I'm not very well-versed in naval/maritime knowledge. I thought later with a boiler explosion that would very well indeed create a LOT of problems.

So instead I might write that the cargo vessel is more like a ghost ship (not literally of course) that ended up sailing into the harbor without responding to any hails from the port authority or coast guard. The ship scraped alongside a pier and sustained some damage but is still afloat. What's eerie is that there doesn't appear to be anyone aboard....other than signs of chaos. Blood spatter, bullet holes, discarded Kalashnikov rifles and shell casings with other ominous signs are everywhere but no corpses....except for the captain, who if found is inside his locked cabin, dead from a self-inflicted pistol shot to the head with his eyes frozen in sheer horror. And the power system to the ship appears to have failed, so again it's dark with only the emergency lighting now on.

Instead of daytime, it's nighttime....within hours of the incident the heroes are flown to the site to investigate what exactly happened, and it's snowing and freezing cold. As for where this is taking place, New York harbor. So most likely NYPD, Port Authority and Coast Guard will be on the scene.

So, now back to how one should approach a search of the ship when they believe a high value target or cargo is in the interior. Are there anything to consider in particular or should it go somewhat similar as one would consider doing MOUT in a room-to-room, corridor by corridor tactical situation?

As for the supernatural horror in question, let's just say I'm going for a bit of a Lovecraft vibe.

The search is going to be similar to multi-storey building search except that most work ships (i.e. anything that isn't intended to carry paying passengers) don't need wide open corridors.
While main passageways typically allow space for two people to pass each other, secondary passageways and stairwells are often only wide enough for one person at a time and you won't get a lot of capacity for overwatch as the person you'd be covering will effectively be blocking your view down the passageway/stairwell.

Any combat in these areas is going to require the second man to be shooting over the shoulder of the lead man (or around his torso, hips etc. etc.) unless the lead kneels or ducks down to allow unobstructed view for the second guy. Naturally enough, conducting a search like that takes much longer

I would recommend taking a look at many of the pages found here

but specifically this sub-heading

While not all the schematics are big enough to use for mapping purposes, a lot of the images can give you ideas as to the limited space you have inside a work ship.

Although the following link is for an icebreaker, there's a lot of photos of various areas on the ship that may also prove helpful for getting a feel for the space constraints any searchers would have to deal with.

Same with this one although this is a research ship

For military and Coast Guard units the mission is called Visit, Board, Search and Seizure.

Coast Guard law enforcement personnel and Navy Masters of Arms will do 'permissive' mission," where they do not expect "significant active resistance." Marines will execute non-permissive missions in-extremis, but the Navy Seals are THE world experts on the mission. Often Navy surface combatants will order ships to strike colors/surrender and fire across their bow, or if required disable them by cannon fire rather then risking personnel.

Will not talk much about tactics beyond saying they are done either TOP down via Helo insert, or bottom up via boarding from small craft.

Potential for losses are very high. It's a very challenging mission to do right.
