Naval Architecture &
Marine Engineering

From concept design through detailed conversion projects — Akkan Maritime's in-house naval architects deliver stability calculations, FEA structural analysis, CFD flow analysis and class-society-grade documentation across every vessel segment.

25+ years of delivered engineering

A track record built on calculations that hold up

From the first stability report in 2003 to today's complex floating drydock designs, every project leaves a paper trail that has been audited, approved, and signed off by IACS member societies.

Core Capabilities

What our naval architects deliver

Whether you need a single calculation for a regulatory filing, a full FEA campaign for a major conversion, or a complete concept design package — our engineering team can deliver, partially or completely.

∫

Stability Calculations

Intact and damaged stability assessments, IMO compliance, longitudinal strength analysis, trim & list studies, light ship verification.

⊞

Finite Element Analysis (FEA)

Structural FEA for newbuilding and conversion projects, fatigue analysis, A-frame and crane stress assessments, panel buckling studies.

≈

CFD Flow Analysis

Computational fluid dynamics for hull resistance, propeller-hull interaction, wake field optimization, energy efficiency studies.

⛟

Conversion Projects

End-to-end conversion engineering — major hull modifications, deck rearrangements, mid-life upgrades, FSO/FPSO conversions.

▦

Stockholm Calculations

RoPax stability under SOLAS Stockholm Agreement, water-on-deck analysis, damaged stability for passenger vessels.

▭

Panama Canal Structural Design

New Panama Canal structural design compliance, Neo-Panamax dimensional optimization, transit-specific structural analysis.

Concept Design Specializations

Vessel types we design from the keel up

Decades of focused experience in specific vessel families — these are the segments where Akkan Maritime offers full concept-to-delivery design capability, not just selective calculations.

Livestock Carriers

Specialized livestock carrier design including ventilation systems, fodder distribution, manure handling, animal welfare compliance, and structural reinforcement for high-deck-density operations.

Up to 10,500 SQM Fodder Systems Conversion Specialist

Antipollution Vessels

Antipollution boat design for harbour cleaning operations — purpose-built designs with floating debris collection, oil spill response equipment, and shallow-draft maneuverability.

Nordic Type Fishing Boats

Ice-class fishing vessels designed for Nordic and Arctic operations — reinforced hulls, heating systems, weather protection, and accommodation standards meeting Northern European crewing requirements.

Ice 1A / 1B / 1C RMRS Approved Iceland & Faroe

Open Sea Fishing Trawlers

Long-range freezing trawlers and factory vessels for open ocean operations. Our ORCA Class series (35m / 45m / 55m) is designed specifically for North Atlantic conditions with full processing capability.

FEA Case Study

FV Daria — Funnel Beam Structural Analysis

A documented example of Akkan Maritime's structural FEA capability: the funnel beam structural analysis report for the FV Daria (ex-Ocean Concorde) 67m freezer trawler modernization. The study evaluates total deformation, longitudinal, transverse, and vertical displacement under maximum load — calculated using Straus7 finite element software and validated against IACS class rule limits.

Straus7 FEA · IACS Compliant

Brattwaag Winch Foundation Analysis

Beam displacement analysis under 300 kN winch load. Maximum displacement: 0.0016 m. Validated against IACS class structural rules for deck-mounted winch foundations on commercial fishing trawlers.

  • Vessel: FV Daria 814281
  • Analysis tool: Straus7 Release 2.3.3
  • Load case: 300 kN winch pull
  • Class society: RMRS

Funnel beam deformation under maximum load

FV Daria funnel beam — Total deformation result (Figure 17) and longitudinal X-direction (Figure 18)
Figures 17 + 18

Total + Longitudinal Deformation

Maximum total deformation (DMX) of 3.1 mm and longitudinal X-direction range from −0.22 to 0.9 mm — within class-allowable limits for funnel beam structures.

FV Daria funnel beam — Transverse Y-direction (Figure 19) and Vertical Z-direction deformation (Figure 20)
Figures 19 + 20

Transverse + Vertical Deformation

Y-direction deformation range −0.25 to 0.76 mm; Z-direction range −3.04 to 0.19 mm. Stress concentration localized at funnel-deck interface, validated against allowable thresholds.

Engineering deliverable: The FV Daria modernization required complete structural FEA validation for the new funnel and winch installations under RMRS class. Akkan Maritime's in-house engineering team (with IEA Technik) delivered the analysis report, FEA verification, and class-society submission package — enabling the project's successful class approval and entry into service.
