Engineering for land, sea and offshore
We design steel structures, vessels, offshore equipment and mechanical systems from Swakopmund, for clients along the coast of Namibia, Angola and West Africa.
A coastal firm for coastal and offshore work
Coastal Consulting Engineers is an engineering and design consultancy based in Swakopmund. We work where land meets sea: ports and harbours, workboats and vessels, drilling rigs and production units, mines and industrial plants along the coast.
We take a project from first concept to fabrication drawings, with the calculations behind every member, weld and lifting point. The drawings we issue are ready for the workshop, and the reports are ready for the class society or certifying authority.
Services
Four disciplines under one roof, so the structure, the vessel and the systems inside it are designed to work together.
Structural and civil engineering
Steel and concrete structures for industrial, commercial and port sites, designed for coastal wind and corrosion.
- Steel buildings, portal frames, roof covers and canopies
- Platforms, mezzanines, stairways, walkways and railings
- Equipment supports, pipe racks and storage racking
- Foundations, ramps and civil works
- Strengthening and repair of existing structures
Naval architecture and marine engineering
Design and modification of steel workboats and marine structures to class rules.
- Hull structure: frames, decks, stiffeners, bulkheads and engine girders
- General arrangement and safety plans, including redraws from old drawings
- Anchoring, mooring and deck equipment foundations
- Crane and davit bases
- Floating docks, dry docks and pontoons
Oil and gas offshore structures
Structures and equipment for drilling rigs, FPSOs and supply bases, verified for offshore loads and lifting.
- Helidecks and supporting structure
- Lifting beams, padeyes and lifting lugs
- Offshore containers, baskets and equipment stands
- Sea fastening and load-out design
- Deck reinforcement, monorails and crawler beams
Mechanical engineering
Tanks, piping and process equipment for marine, mining and industrial plants.
- Storage tanks for fuel, water, sludge and chemicals
- Piping spools and systems: cooling, bilge, fuel, fresh, grey and black water, HVAC
- Flange and material selection to design pressure
- Pump sizing and selection
- Corrosion allowances and material choices for aggressive service
What we deliver
Design calculations
Hand checks and finite element analysis, written up in reports a reviewer can follow line by line.
3D models
Full 3D models of structures, vessels and plant, so clashes and access problems show up before steel is cut.
Fabrication drawings
General arrangements, part and assembly drawings, and cutting lists for the workshop.
Welding procedures
Weld details and procedure specifications matched to the material and the code.
Surveys and inspection
Structural surveys of rigs, vessels and plant, with thickness gauging, UT and MPI, followed by a report and repair drawings.
3D laser scanning
As-built point clouds of decks, hulls and plant rooms, turned into accurate models and drawings for modifications.
Repair and reinforcement
Repair method statements for steel, FRP and composite repairs of tanks and seawater pipework, with supervision of the field team.
Certification support
Documentation packs for DNV and other class societies, and support through their review.
Software and equipment we use: Rhino, AutoCAD, STAAD.Pro, PROKON, and terrestrial 3D laser scanning.
Standards we design to
Every design is checked against the code that applies to it, and the report says which clause each check comes from.
- DNVOffshore containers, lifting, helidecks and ship rules
- BVBureau Veritas rules for steel ships
- API 650Welded steel storage tanks
- NACECorrosion control and material selection
- ISOSmall craft and international standards
- Eurocode and SANSSteel, concrete and loading for onshore structures
How we work
Brief and site information
You send the scope, loads, drawings or photos. If there are no drawings, we survey and measure on site.
Proposal
A fixed scope, price and programme, so you know what you will receive and when.
Concept and design
We model the design in 3D, run the calculations and agree the layout with you before detailing.
Drawings and report
Fabrication drawings, the calculation report and welding details, issued for construction or for class approval.
Fabrication support
We answer workshop queries, review changes and inspect the work where needed.
Who we work with
- Drilling contractors and offshore operators
- Shipyards, boat builders and vessel owners
- Ports, harbours and supply bases
- Mines and processing plants
- Steel fabricators and workshops
- Industrial and commercial developers
