All the Ways We Keep Ships, Docks
& Owners Out of Trouble
What We Do

Naval Architecture and Marine Engineering
From hull shapes that handle chop beautifully to systems that don’t misbehave mid-voyage — we design vessels that work as good as they look. Because a pretty render is nice, but a boat that does its job? Even better. And when it’s time to prove performance, we make sure the numbers back it up.

Marine
Forensic
Engineering
When something bends, breaks, or leaks, we bring science to figure out what happened and design a fix. We provide expert witness services for clients seeking the truth about their vessel’s condition. We review designs, perform LiDAR scanning, inspections, & generate post-incident reports.

Dry Dock & Shipyard Engineering
Docking plans, structural checks, load calculations when the clock’s ticking. We help shipyards plan smarter layouts, design better docks & manage inspections. When surprises arise, we’re two steps ahead. We partner with DM Consulting & Syncrolift to bring projects to life.

Historical
Vessel
Engineering
We blend careful structural reinforcement, discreet modern systems, and a big dose of respect for the original lines — so your classic beauty stays authentic, seaworthy, and safe to show off for decades more, giving kids a chance to touch history instead of just reading about it.
Naval Architecture & Marine Engineering Services
At TM Marine Services, we believe every marine challenge deserves a practical, clear solution — whether you’re in offshore oil and gas, shipbuilding, commercial marine operations, or running a family-owned boatyard, big fleet or one tough tug, historic schooner or new dry dock — if it floats (or needs help floating), we bring the experience, engineering, and straight answers to keep it working safely and efficiently. No project too small, no problem too complicated — just solutions that make sense.
We run the numbers that keep your vessel balanced in calm seas and rough weather alike — so it stays upright and safe.
Behind every sturdy hull is rock-solid math. We check stresses, reinforcements, and fatigue limits, making sure steel and welds do their job voyage after voyage.
Bilge pumps, ballast tanks, fuel lines, HVAC, firefighting system — the pipes and flows that keep your vessel working behind the scenes. We design these systems to fit tight spaces, run reliably, and pass every code check.
From switchboards and emergency power — we plan your vessel’s wiring and controls so everything lights up, powers on, and stays safe when you need it most.
We don’t just hand over drawings and disappear. Our engineers stay involved during builds, refits, or dry dock work — solving surprises on site and making sure the finished job matches the plan.
Missing the drawings of your ship and needing to make new ones for regulatory purposes? No lines plan and trying to dry dock on fixed blocks? Wanting to perform a retrofit or upgrade, but you can’t find the structural plans? We scan every surface in 3D, capturing millimeter-accurate data that helps upgrades, repairs, or forensics go exactly right.
Preserving history means preserving old plans, too. We convert fragile paper blueprints into clean digital files and 3D models. Often scanned old plans can be huge picture files that are difficult to view or interpret on modern computers. We can take those plans, interpret them, generate a 3D CAD model, and produce a full set of modern blueprints for your historical vessel.

Floating Pool Barge
Horseshoe Bay Resort, Lake Lyndon B. Johnson, TX
- Horseshoe Bay Resort, Lake Lyndon B. Johnson, TX
- Project On Time
- Impact-resistant HDPE + Custom Aluminum Framing
- Pure joy (with lake views)
Imagine sipping something cold while floating on the lake instead of just next to it. Travel + Leisure called it one of the most unique resort features in Texas. We engineered this HDPE barge to support an entire pool — safely, sustainably, and stylishly — right in the heart of one of Texas’s most stunning resorts. It’s strong, low-maintenance, and built to handle sunshine, splashes, and serious cannonballs. As Forbes put it, it redefines lakeside luxury.
Battleship Texas Restoration
Gulf Copper Shipyard, Galveston, TX
- Gulf Copper Shipyard, Galveston, TX
- Heavy-duty steel renewal, hull plating, and internal structure reinforcement
- Extending the life of a national icon — without compromising its legacy
The only surviving battleship to have served in both World Wars needed more than a fresh coat of paint — she needed structural surgery. We partnered with TM Marine Services to assess fatigue damage, renew critical steel sections, and restore stability for her next chapter. The work had to be precise, fast, and faithful to the original — a challenge worthy of the ship’s legacy.
Other key projects include:
- USS Orleck Shell Plating Repair
- Elissa Tall Ship Dry Docking & Lidar Scanning
