Marine & Shipbuilding Engineering Services
Delta Precision Group provides managed marine engineering teams for both new build and retrofit projects, carrying a design through concept, basic design, 3D modeling, and production drawings on the way to the yard, for firms that need capacity without adding permanent staff.
01 / WHEN MARINE CAPACITY IS TIGHT
Built for yards and firms whose vessel projects outgrow their bench.
Shipyards and marine engineering firms with a design backlog
Where a new build or retrofit project has outgrown current design bandwidth — often the project manager waiting on production drawings before a slot at the yard closes.
Firms that need an existing vessel scanned into an accurate model
Before modification work can even be scoped — often the engineer trying to reconcile a retrofit scope against a vessel with no reliable as-built documentation.
If either of those is your situation, tell us where things stand.
02 / THE ENGINEERING CAPACITY GAP
Why shipyards and marine firms bring in outside engineering capacity.
Marine design carries two very different risk profiles depending on the project type. A new build has to work through concept design, basic design, and detailed 3D modeling before a production drawing is finalized and sent to the yard, and a mistake carried through that sequence compounds at every stage after it. A retrofit depends entirely on how accurately the existing vessel is captured: a 3D scan that misses a deformation or an undocumented prior modification means the retrofit design is built on a false premise before it even starts.
Hiring to cover a marine project surge is slow, and a generalist offshore drafting shop can produce a general arrangement drawing without necessarily understanding classification society requirements or how a retrofit scope actually needs to reconcile with scan data. Marine engineering is a judgment discipline built on naval architecture principles, not a pure drafting task.
We build our teams around people who understand the difference between new build and retrofit work, and design accordingly rather than treating every project the same way.
03 / FROM CONCEPT TO PRODUCTION DOCUMENTATION
Marine engineering support from concept and basic design through 3D modeling and production drawings.
Deliverable 01
New build design support
Support across the full new build sequence: concept design, basic design, detailed 3D modeling, and finalized production drawings ready to hand off to the yard.
Deliverable 02
Retrofit and modification design
Design support for modifications to an existing vessel, starting from a 3D scan of the ship to establish an accurate as-built baseline before any modification design begins.
Deliverable 03
Structural and general arrangement drawings
General arrangement drawings and structural scantlings developed to the applicable classification society’s requirements.
Who this is for: shipyards and marine engineering firms managing new build or retrofit projects with design capacity that doesn’t match current volume, and firms that need an accurate as-built model of an existing vessel before retrofit design can start.
04 / FROM DESIGN INPUTS TO YARD DOCUMENTATION
How we develop marine engineering work through each stage of the design process.
-
New builds follow the sequence the project needs. For a new build, we follow the design sequence your project actually needs: concept design to establish the overall vessel parameters, basic design to develop the core systems and arrangement, 3D modeling to work out the detail, and production drawings finalized and checked before anything goes to the yard.
-
Retrofits start from a 3D scan of the vessel. For a retrofit, we start from a 3D scan of the existing vessel, since a modification design built on outdated or assumed as-built information creates rework once it reaches the yard, and we reconcile the scan against your modification scope before detailed design begins.
-
We align with your engineer of record at every stage. Either way, we align with your engineer of record on classification requirements and design intent at each stage, not just at handoff.
05 / MARINE ENGINEERING EXPERTISE
The design, modeling, analysis, and production-documentation capabilities behind our work.
Capabilities our team is equipped to deliver
- New build design support from concept through finalized production drawings
- Retrofit and modification design starting from 3D scan data
- General arrangement drawings and structural scantling development
- Coordination with classification society requirements (ABS, DNV, Lloyd’s Register, and similar)
Scope, project type (new build or retrofit), and the governing classification society are confirmed with you before design work begins.
06 / THE DELTA PRECISION GROUP DIFFERENCE
Managed marine engineering capacity built around your vessel, standards, and schedule.
We design differently for a new build than we do for a retrofit, because the two carry fundamentally different risks.
A new build lives or dies on getting the design sequence right from concept forward, while a retrofit lives or dies on how accurately the existing vessel was actually captured. Treating both the same way is how design errors compound silently until they reach the yard.
We’re built for shipyards and firms with recurring marine design needs.
Though a single new build or retrofit project is a reasonable way to start.
07 / FIND THE RIGHT FIT
Choose the engineering support model that fits your vessel project.
Dedicated production capacity
An ongoing team sized to your marine design pipeline across new build and retrofit projects.
Project capacity
A single new build or retrofit project with a defined scope and deadline.
Surge and overflow support
Additional design capacity ahead of a yard deadline or a staffing gap.
Not sure which fits? Tell us your project scope and we’ll recommend the right approach.
08 / FAQ
Frequently asked questions about marine and shipbuilding engineering services.
Will a retrofit design actually match the real condition of the vessel, or be based on outdated assumptions?
We start every retrofit from a 3D scan of the existing vessel, so the modification design is built against the actual as-built condition, not an assumed one.
Do you handle both new build and retrofit work, or just one?
Both, and we design each differently. New build work follows the full concept-to-production-drawing sequence; retrofit work starts from scan data and works forward from there.
Have you actually done marine design work, or is this generalist structural drafting?
Our teams are built around naval architecture and marine engineering specifically, working to classification society requirements, not a generalist structural pool.
Will back-and-forth slow the project down instead of speeding it up?
We align with your engineer of record at each design stage, concept, basic design, and detailed modeling, rather than waiting until a full package is done to surface issues.
How do you handle sensitive vessel data and drawings?
Data handling is confirmed with you at the start of every engagement, matched to your firm’s and client’s requirements.
