Detailed Section-Wise Syllabus for GATE 2026 NM
1. General Aptitude (15% Weightage)
This section is common to all GATE papers. It assesses verbal, quantitative, analytical, and spatial skills.
Verbal Aptitude: Grammar, vocabulary, and reading comprehension.
Quantitative Aptitude: Data interpretation, numerical estimation, ratios, and percentages.
Analytical Aptitude: Logic, deduction, and numerical relations.
Spatial Aptitude: Mirroring, rotation, and pattern recognition.
2. Engineering Mathematics (13% Weightage)
Mathematics acts as the foundation for the complex calculations found in ship hydrodynamics and structural analysis.
Linear Algebra: Matrices, determinants, and eigenvalues.
Calculus: Multi-variable calculus, Stokes, Gauss, and Green’s theorems.
Differential Equations: First and higher-order ODEs and PDEs.
Probability & Statistics: Distributions and statistical analysis.
3. Applied Mechanics and Structures (Core NM)
This section focuses on the physical strength of maritime vessels.
Engineering Mechanics: Free-body diagrams, trusses, and kinematics.
Mechanics of Materials: Stress-strain relationships, Mohr’s circle, and torsion.
Vibrations: Free and forced vibration of single degree of freedom systems.
4. Fluid Mechanics and Marine Hydrodynamics
Essential for understanding how ships interact with the water.
Fluid Properties: Statics, stability of floating bodies, and conservation laws.
Potential Flow Theory: Sources, sinks, doublets, and Kutta-Joukowski theorem.
Viscous Flow: Navier-Stokes equations and boundary layer theory.
5. Naval Architecture and Ocean Engineering
The heaviest section, focusing on ship-specific design and environmental factors.
Ship Geometry: Archimedes’ principle, buoyancy, heel, and trim.
Resistance & Propulsion: Ship resistance components, propeller design, and cavitation.
Ocean Engineering: Fixed and floating offshore platforms (Jackets, FPSOs, TLPs) and physical oceanography.
6. Thermodynamics and Marine Engineering
Covers the powerhouses that move the vessel.
Basic Thermodynamics: First and Second laws, Carnot cycle, and gas power cycles (Diesel/Otto).
Marine Diesel Engines: Two/four-stroke engines, turbocharging, and MARPOL regulations.
Auxiliary Systems: Pumps, heat exchangers, and oily water separators.
Key Topics and Weightage Analysis
To optimize your study plan, focus on these high-priority areas:
Topic | Approximate Marks | Priority |
Ship Stability & Geometry | 20–25 | High |
Marine Hydrodynamics | 15–18 | High |
Marine Diesel Engines & Thermo | 15–18 | Medium |
Mechanics of Materials | 10–12 | Medium |
Ocean Engineering | 5–8 | Low |
Frequently Asked Questions (FAQs)
Q1: Is there negative marking in GATE NM 2026?
Yes, but only for MCQs. A 1/3 mark is deducted for a wrong 1-mark question, and 2/3 mark for a 2-mark question. There is no negative marking for MSQs or NATs.
Q2: Which books are best for Marine Engineering?
Naval Architecture for Marine Engineers by Reeds.
Engineering Thermodynamics by P.K. Nag.
Fluid Mechanics by R.K. Bansal.
Q3: Can I attempt the NM paper if I have a Mechanical Engineering degree?
Yes, candidates with a background in Mechanical, Civil, or Aeronautical engineering often find the NM paper a viable option due to the overlapping concepts in Fluid Mechanics and Thermodynamics.
