Naval Architecture & Marine Engineering Services
For Ships, Boats, and Stories Worth Keeping Afloat
Welcome to TM Marine Services
Where precision meets seaworthiness, math meets metal, and your vessel (big or small, old or new) gets exactly the engineering brainpower it deserves.
Every ship has a story — and every story deserves a team that knows how to keep it safe, stable, compliant, and performing at its best. From dry dock headaches to historical preservation miracles, it all starts with these core services.
Our Core Services
1. Stability Calculations
Because Floating Is Non-Negotiable
We make sure your ship or boat stays balanced in calm seas and when the ocean tries its worst tricks. Whether you’re launching a new vessel, adding a fancy crane, or just want peace of mind for inspections — we run the numbers that keep you upright.
How we use it
- Dry Dock & Shipyard plans
- Historical vessel retrofits that don’t ruin her charm
- New builds and major conversions
- Damage scenario plans for marine forensics
From intact to “oops we hit something,” we calculate it all — so you don’t tip your coffee or your deck cargo.
How we use it
- Checking old ships for hidden weak spots
- Approving new deck houses or supports
- Forensic reports after dents, cracks, or worse
- Sign-offs for dry dock repairs and upgrades
No guesswork. No surprise failures. Just clean, solid confidence in every bulkhead and beam.
2. Structural Calculations
Stress-Tested So You Don’t Stress
Your hull and structure handle pounding seas and heavy loads every single voyage. We make sure the steel, welds, and frames do their job — and keep doing it.
3. Marine System Design
The Hidden Workhorses, Engineered Right
Bilge, ballast, fuel, cooling — the veins and arteries of your ship. We design systems that work efficiently, fit tight spaces, and meet every code.
How we use it
- Modernizing historical vessels without losing authenticity
- Optimizing new builds for clean flows and easy maintenance
- Retrofit projects in the yard without expensive surprises
Good systems mean no clogs, no leaks, no headaches — only smooth sailing.
4. Electrical Design
Power Where You Need It (Without Blackouts)
Lighting, radar, pumps, radios — all run on juice. Our electrical design keeps your vessel bright, safe, and ready, whether she’s a busy workhorse or a lovingly restored icon.
How we use it
- Dry dock upgrades — panels, switchboards, cabling
- Historical vessels — discreet modern wiring
- New builds — redundancy and future-proofing
- Forensic support — tracing shorts and failures
5. Construction Engineering Support
Smooth Builds, Zero Drama
We don’t just design and disappear — we roll up our sleeves at the yard, too. From dry dock docking checks to mid-project tweaks, we make sure the build or repair matches the plan.
How we use it
- On-site support during shipyard projects
- Real-time solutions when plans meet reality
- Coordinating owners, crews, and yard teams so everyone agrees
- Wrangling paperwork and inspectors (we’ve seen it all)
No lost time. No finger pointing. Just a project that moves.
6. LIDAR / Laser Scanning
Bought missing drawings of your boat? We can help with that.
Many owners aquire vesses without any drawings of their ship. Additinally, ships and boats twist, settle, and get “customized” by years of service. Our laser scanners capture reality — fast and accurate down to millimeters — so you get an exact digital twin to design around.
How we use it
- Documenting hulls for dry dock or yard work
- Scanning historic vessels before restoration
- Planning upgrades that fit the first time
- Providing plans for regulatory compliance verification
- Supporting forensic investigations when “what happened?” is a mystery
Goodbye guesswork. Hello perfect fit.
7. Digitizing Historical Ship Plans
Preserving the Past, Preparing for the Future
Old plans fade. Pencil lines smudge. Scanned plans become Gigabytes of digital files – difficult to email or even open on some computers. We turn those fragile pages and huge files into clean, detailed, modern CAD files and 3D models, ready for restorations, replications, or insurance archives.
How we use it
- Historical vessel engineering — our passion!
- Smooth restorations true to the original lines
- Owners who want to future-proof their boat’s legacy
We protect stories — one blueprint at a time.
Where We Apply These Services
Our toolbox works best in places where cutting corners is not an option — where precision, speed, and a deep respect for vessels and their owners make all the difference. Here’s where you’ll find us at our best:

Naval Architecture
This is where your vessel’s story begins — and sometimes, where we help write a thrilling new chapter. We shape hulls that glide through water with less drag, design weight plans that keep you stable no matter what you haul, and integrate new systems or superstructures without messing up performance. Whether you’re building fresh from scratch, retrofitting for new duties, or fine-tuning an existing workhorse for better fuel economy, our naval architects sweat every detail. Beautiful lines, smart hydrodynamics, bulletproof compliance. That’s what we deliver.

Historical Vessel Engineering
We have a soft spot for classic hulls and stories etched in teak and rivets. For us, old ships are living treasures, not headaches. We balance modern safety and regulatory requirements with a gentle touch: hidden reinforcements, upgraded systems no one sees, new plans faithful to the originals. Whether you’re preserving a museum piece, restoring a century-old schooner, or giving new life to a heritage ferry, we protect history with care and smart engineering that stands the test of time.

Marine Forensic Engineering
When something goes wrong — and occasionally, it does — you need facts, not guesses. We step in with clear, science-backed answers. Our forensic team investigates damage, structural failures, mysterious leaks, or stability mishaps. We gather the evidence, crunch the data, and deliver reports that make sense to insurers, lawyers, and yard managers alike. And we don’t just diagnose — we guide you through repairs, claims, and prevent repeat problems. No drama. Just truth and solutions.

Dry Dock & Shipyard Engineering
When your ship or boat hits the blocks, every hour counts. We plan every docking with care: the cradle, the block arrangement, the tide window — nothing left to chance. Once she’s out of the water, we inspect, calculate, scan, and solve problems fast so your project stays on schedule and on budget. Need a last-minute fix? We’ll find the most practical solution that keeps everyone — yard crew, owner, and inspector — nodding yes. Less downtime. Fewer surprises. Better results.
No mater your vessel type — a busy commercial ship, a sturdy tug, a fast ferry, or a classic sailboat that makes heads turn — you’ll find our team treats every vessel like she’s our own. We love this work, and it shows.
