A holistic approach to the all-electric ship

IFAC Proceedings Volumes, 2004
Abstract The advances that have been made in computing technology over the past 20 years have brought us to the point where it is possible to institute an effective Condition Based Maintenance (CBM) strategy for the all-electric ship. With a good collection of equipment health information, condition based maintenance can be employed in the management

All Electric Ship electromagnetic signature. A twenty megawatts podded ship

Europe Oceans 2005, 2005
Today, many ships, cruise liners and Navy vessels, use an electric podded propulsion. These "All Electric Ships" (AES) need an important electric power. Consequently, high currents in extremely low frequencies (ELFE), flow through cables and equipment. These alternative currents could generate important underwater electromagnetic field.

A Resilience-based Comprehensive Evaluation Framework for All-Electric Ship

2021 IEEE 12th Energy Conversion Congress & Exposition - Asia (ECCE-Asia), 2021
The shipboard power system of an all-electric ship can be characterized as an isolated microgrid system with limited capacity and no support from external grid. Its resilience problem is more prominent when confronting some extreme events, compared to land-based power system.

Notional all-electric ship thermal simulation and visualization

2009 IEEE Electric Ship Technologies Symposium, 2009
The impact of unpredicted or unplanned thermal disturbances on any future all-electric ship may well lead to unexpected and untimely failure of mechanical-electrical systems [1] (e.g., power electronics, high power sensors, and pulsed weapons) to the detriment of the ship's combat mission.

Predictive energy management for MVDC all-electric ships

2017 IEEE Electric Ship Technologies Symposium (ESTS), 2017
The integration of energy storage devices is essential to handle the high-power ramp-rate loads in all-electric ships. This paper presents a novel predictive control method to manage the energy flow among distributed resources including generators and a bulk energy storage.

Condition-based Optimal Maintenance and Energy Management of All-electric Ships

IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020
This research paper focuses on coordinated operation scheduling of the condition-based maintenance and energy management of an all-electric ship (AES). The condition-based maintenance comprises of risk assessments, short-duration main-tenance, and condition monitoring of the critical components.

Dependability analysis of cyber security in All-Electric Ships

2018 AEIT International Annual Conference, 2018
The Internet of Things frameworks can improve quality and performance of controlled system but also leading the system to be weaker from the cyber security point of view: new devices can be used to exploit system vulnerabilities with malicious intentions.

Dependable design assessment of Integrated Power Systems for All Electric Ships

Electrical Systems for Aircraft, Railway and Ship Propulsion, 2010
For future All Electric Ships (AESs), setting up of a dependable Integrated Power System (IPS) requires a dedicated design procedure, more articulated than the traditional ones. As a matter of fact, traditional procedures need to be revised and supplemented using an appropriate approach in order to make the IPS dependable.

Notional all-electric ship systems integration thermal simulation and visualization

SIMULATION, 2012
This work presents a simplified mathematical model for fast visualization and thermal simulation of complex and integrated energy systems that is capable of providing quick responses during system design. The tool allows for the determination of the resulting whole system temperature and relative humidity distribution. For that, the simplified physical

NSGA-II for joint generation and voyage scheduling of an all-electric ship

2016 IEEE Congress on Evolutionary Computation (CEC), 2016
The non-dominated sorting genetic algorithm II (NSGA-II) is applied to the concurrent generation scheduling and load management of the isolated microgrid: the joint generation — voyage scheduling of an all-electric ship (AES). The AES uses integrated power generators and an energy storage system (ESS) to match its propulsion and service loads, thus ...
