Solutions

Each boat being a unique technical and industrial challenge, NES proposes custom solutions !

Boat : a program and missions

Due to its missions and navigation program, a boat is a unique achievement. However, they can be grouped into categories wich directly influences the manufacturing methods and the relevant classification.

Experienced in implementing these characteristics, NES is directly operational on leisure boat projects, such as small units or luxury yachts, or commercial boats projects, such as passenger ships or workboats.

Design to manufacture

Designing aims to enable and facilitate manufacturing. NES harmonizes its solutions according to the processes and tools used by the manufacturer.

Materials : center of the design process

Knowledge of materials specificities is essential to ensure technical choices consistency. Conception intent to make the most of materials mechanical characteristics and to ease their implementation.

NES optimizes its solutions whether composite, aluminum, or steel are used.

Project outlines

Preliminary design : technical validation of a concept

Ideas and concepts are at the beginning of every projects. It can be an innovative new construction concept, or a refit aiming to increase its energy efficiency. During the preliminary design, project technical feasibility is checked.

NES offers solutions at each concept analysis key stages.

Naval architecture : an iterative spiral

In addition to specific missions and navigation program, boats are also sailing : therefore design constraints are multiple. Their achitecture is estimated in pre-project phases and iteratively refined along development.

At each dimensioning step, NES proposes dedicated iteration tools.

Hull shape definition
Weight estimation
Stability criteria verification
Performance prediction and engine selection
Structure estimation
General arrangement
Main equipments selection and layout
Regulatory checks (freeboard, falls overboard, safety, ...)

Safety regulations

To ensure crews and navigations safety, rules from flag (Affaires Maritimes) or classification societies (Bureau Véritas, DNV, ABS, …) impose additional design constraints.

NES supports you in these constraints implementation and in regulatory files preparation.

Regulatory compliance study
Regulatory file: drawings and documents
User manuals

Project details

Naval engineering for systems integration

With multiple onboard equipments, boats are complex systems assemblies. Their sizing and integration require calculation tools and naval engineering methods. This is confirmed with energy-efficient propulsion expansion, resulting in more complex on-board assemblies.

NES applies naval engineering principles to optimize systems performances.

CAD : technical language

2D and 3D models are standardized representations of concepts, projects and technical studies. They are technical exchanges main elements, from preliminary design to manufacturing.

At each phase, NES offers tailor-made modeling and drafting solutions.
