Concept development and design basis

Together with Ship owner and operator we define operational, technical and safety requirements, by analyzing operation philosophies with regards to the new hydrogen technology.

In addition we study the impact of rules and regulations on system design and layouts. Both class and Authoritiey requirements are evaluated and defined. 

Further the new operational profiles and energy analysis are evaluated and performed, to set the basis for energy demands and refilling strategies.

Hydrogen integreation to Ship, General physical assessments

Next stage involves the first evaluations regarding ship construction vs naval architechture vs hydrogen system. All Shipowners 45 vessels are evaluated in a feasibility study. 

General arrangement drawings, layouts and main system documentations are analyzed and compared.

A preliminar system design is performed, given design basis requirements.

The approval process

In parallel to the design activities, the approval process is initiated.

Hydrogen installations in maritime applications is as per today not covered entirely by specific rules or regulations. 

A brief safety, rules & regulations and classification overview;

Design and process towards approval

Our design team is the entity (H2Tech, Partners, Shipowner and Operator) that carries out the design development and analyses for the alternative and/or equivalent design.

Together we are in a position to assess safety and environmental protection holistically, and also be responsible for the education of operations personnel, documentation on board and integration with the safety management system.

Operational and technical experts in the relevant field or from similar operations should be involved and assist the design team in the review of hazards as well as supply expertise to the initial risk assessment sessions. Hence a high level of understanding of

the concepts is required. H2Tech collaborates with DNV GL, Gerd Petra Haugom and her team, to manage the Hazid's and and safety issues.

H2Tech is the managing developer of the design seeking approval. We are familiar
with alternative and/or equivalent design approaches in order to utilize them, and 

achieve the approval by the approval Authority and Class(DNV GL).

Detailed system design and development.

 In addition to a General arrangement(GA) of the system and layouts, the preliminary system design includes the Piping and instrumentation diagram(P&ID) and electrical Single line diagram(SLD).

The main disciplines in the detailing phase are process, marine structural, electric and safety engineering.




Engineering and development scope.

In addition to the Authorities and Class document requirements, which focus on process engineering and safety, the following engineering and developing scope applies; 

Together with Sintef and Westcon we develop the ideal system balance, control and efficiency, including the right hybrid hydrogen and batteriy balance of energy amounts.

This scope includes;

Optimisation of operating conditions and control strategies, as well as identification of critical parameters for high efficiency and long lifetime. 

Power and Automation technoloy and design; solutions for machinery and safety, including Ship Automation, Drives, EMS(energy management system), PMS(power management system).

Marine engineering and Naval architechture;

Defining the optimum ship department configuration and application layout for the hydrogen system to be installed and work day-in, day-out with other systems on board. 

Validation of the system in laboratories.

Construction and calculations;

Based on 3D parametric and dynamic simulation we develop the total system model with all detailed module interfaces(all systems). Includes; Layouts, assembly and mechanical interface documentation.

Finally we build, install, test and start operating H2MW on the first ship!

SINTEF Laboratoy


Together with partners, H2Tech are developing the optimal maritime hydrogen system.

Decades of experience in developing world-class marine concepts and products, together with our passion for a sustainable technology development, will ensure success.


In order to achieve commercialization of a cost-effective system, we base the development requirements on a commonalities-study of the many ship types in operation.

The study identifies technical application similarities which gives us the possibility to design an ideal wide range modular energy system. 

The H2MW system and modules will fit all ship categories, new buildings and conversions. 


Let us please present our method and some of the development scope. The sketches and image clips below are examples from our latest hydrogen vessel projects. H2MW's scope related to developing an optimal and scalable, module based hydrogen system, is not similar these sketches.
