Shipwreck and Buried Treasure Combo Seeds
Ocean Seeds · By the ChunkScan Team · Updated 2026-09-02
A shipwreck and a buried treasure chest within walking distance of spawn is one of the strongest early-game setups in Minecraft. Shipwrecks can carry a map chest pointing to buried treasure, and the treasure itself guarantees a heart of the sea, the key ingredient for a conduit. Finding both structures naturally close together, without hours of boating, is rare: out of more than 1.7 million seeds scanned in our database, only 20 pass the filters for this combination. The ten seeds listed below are the best of that set. Each one was verified by scanning the actual world generation, so every coordinate shown is where the structure really generates in Java Edition.

Why shipwrecks and buried treasure belong together
Shipwrecks generate with up to three chests: a supply chest with food and materials, a treasure chest with iron and gold, and a map chest that can hold a buried treasure map. Following that map leads to a chest that always contains a heart of the sea, plus a mix of iron, gold, emeralds, and prismarine crystals. Combine the heart of the sea with eight nautilus shells and you have a conduit, which grants underwater breathing, night vision, and faster mining in a large radius. A seed where both structures sit near spawn compresses that entire progression into the first in-game day.
What makes a good combo seed
Distance is the first filter: anything under roughly 250 blocks from spawn is reachable before the first night. Second is clustering. A shipwreck plus multiple treasure chests in the same direction beats two structures on opposite sides of the map. Third, look at the supporting cast. Ocean ruins add drowned farming and buried treasure maps of their own, ruined portals offer early gold and a shortcut toward the Nether, and a beach spawn means you skip the swim entirely. Several seeds below stack all of these within a few hundred blocks.
How ChunkScan verifies these seeds
Every seed in our database comes from scanning real world generation with the cubiomes library, the same algorithms Minecraft uses internally. The scanner generates each world's structure placements and biome layout, records every structure within about 1,000 blocks of the spawn point, and stores exact x and z coordinates plus the straight-line distance from spawn. The list on this page is not curated by hand or copied from forums; it is the direct output of those scans, filtered for seeds where shipwrecks and buried treasure generate close to spawn. If a coordinate is listed, the structure is there.
Seed -9223345425736603125: four treasure chests off one beach
This is the standout of the set. You spawn on a beach with a buried treasure chest just 46 blocks away at x 73, z 137, and a shipwreck 67 blocks out at x 64, z 64. Three more treasure chests generate along the same stretch, at distances of 124, 147, and 161 blocks, meaning four guaranteed hearts of the sea within 165 blocks of spawn. A ruined portal at x 48, z 0 rounds out the loot loop. Everything sits in one tight cluster, so a single short expedition covers all six structures.
Seeds -9222967412756367343 and -9222887857968393231: treasure plus trial chambers
Seed -9222967412756367343 spawns you in a taiga with trail ruins only 80 blocks away, a shipwreck at 147 blocks, and two buried treasure chests roughly 66 blocks apart from each other at x 345, z 105 and x 361, z 41. Trial chambers at 229 blocks give the run a mid-game target. Seed -9222887857968393231 flips the order: buried treasure comes first at 136 blocks from a birch forest spawn, with a ruined portal, ocean ruin, trial chambers, and a second treasure chest all between 217 and 233 blocks, and a shipwreck at 250.
Seed -9223103620573813429: the full ocean structure lineup
If you want variety over raw treasure count, this forest spawn packs five different structure types into one corridor. Trial chambers sit 101 blocks away, a shipwreck at 135, a ruined portal at 150, an ocean ruin at 182, and an ocean monument at just 222 blocks, unusually close for a monument. The buried treasure is the far point at x -231, z 409, 325 blocks out. That makes this seed a strong pick for a permanent ocean base: conduit materials, a guardian farm site, and a portal all within render distance of each other.
Practical tips for the treasure run
Buried treasure chests generate at chunk coordinates ending in 9, usually under sand or gravel on a beach, so dig around the X on the map rather than only at its center. Bring a shovel and a door; the door creates an air pocket for digging underwater. Loot the shipwreck's map chest first if you want extra treasure maps beyond the coordinates listed here. Watch for drowned near ocean ruins, since they attack with tridents at range. Cook the raw cod and salmon from shipwreck supply chests, and save any TNT from treasure chests for mining later.

Frequently Asked Questions
Do these seeds work on Bedrock Edition?
No. All ten seeds listed here were scanned on Java Edition, and structure placement differs between editions. The same seed number on Bedrock will generate different shipwreck and treasure locations.
What is always inside a buried treasure chest?
Every buried treasure chest contains exactly one heart of the sea. The rest of the loot varies and can include iron and gold ingots, emeralds, diamonds, prismarine crystals, TNT, and cooked fish.
How rare are shipwreck and treasure combo seeds?
Quite rare at these distances. Of the 1.7 million-plus seeds scanned in the ChunkScan database, only 20 meet this page's filters for shipwrecks and buried treasure generating close to spawn.
