Information To Be Provided When Asking About Marine Power Solutions

Power solutions for marine design and optimization, need to know the following information, to ensure the high efficiency, safety and compliance:

• basic information. Ship types and purposes

- cargo ships, passenger ship, fishing boat, yacht, warships or special ships?

- the main navigation area (ocean, coastal and inland river) and the operation mode (continuous navigation dock or intermittent)?

 

• Power demand scenarios:

- regular electricity (propulsion systems, lighting, navigation)?

- special requirements (reefer container, scientific research equipment, weapon system)?

- is there a port to use shore power requirements?

 

• Technical parameters:

Load analysis - list all key equipment (power, voltage, running time, peak demand). To distinguish between critical load (such as emergency lighting, communication) and non-critical loads.

 

• Power supply configuration:

- existing power type (diesel generators, batteries, solar energy, etc.) and capacity.

- whether you need a hybrid (such as diesel + battery) or redundancy design?

 

• Voltage and frequency standard:

- system voltage (440 v AC, DC 24 v) and frequency (50 hz / 60 hz).

- if we need more than one voltage compatible design?

 

• Environmental requirements

- to meet the discharge standards (IMO Tier III, sulfur oxide restrictions)?

- whether the tendency to clean energy (hydrogen fuel, LNG, solar)?

 

• Space and weight limit

- equipment installation area size and bearing capacity.

- need to modular design to save space?

 

• Regulatory certification

- must be in accordance with specification (e.g., IMO, IEC and classification standard).

- whether you need explosion-proof, salt fog resistance, or seismic certification?

 

• Budgets:

- limits of initial investment and operational cost expected for a long time.

- whether to give priority to the whole life cycle cost (LCC) optimization?

 

• Operational capacity:

- technical background and the complexity of maintenance crew acceptance.

- whether you need remote monitoring and predictive maintenance function?

 

• Special requirements for Redundancy and reliability

- whether to ask the N + 1 redundancy or black start capability?

- emergency power supply (UPS, backup generators) of battery life requirement?

 

• Intelligent requirements:

- integrated energy management system (EMS) or automation control?

- whether to ship the Internet of things (IoTS) docking?

 

• Time planning

- design, installation, debugging, expected time nodes?

- whether facing emergency reconstruction demand?

 

• Existing problems (if applicable)

- the current power system (such as frequent failure, low efficiency.

- historical accident or compatibility problems.
