Offshore vessels and ships are islanded power systems. Maintaining the operation during the adverse system operating conditions is a challenge. This paper reviews the concepts to improve the protection and operation using the advanced system protection and new developments of the simulating process.
Underfrequency (UF) schemes are implemented in nearly every power system and are deemed critical methods to avert system-wide blackouts. Unfortunately, UF-based schemes are often ineffective for industrial power systems. Traditional UF schemes are implemented in either discrete electromechanical relays or microprocessor-based multifunction relays. Individual loads or feeders are most commonly shed...
Because of anticipated occasional hydraulic issues in an oil sands slurry pumping application, it was expected that the existing Adjustable Speed Drive (ASD) driven 2500 HP motors would be overloaded at up to 3333 HP at a slightly reduced speed from time to time. Working from factory test data, estimates were made of losses and temperature rises at the expected load points. The temperature rises were...
This paper addresses the causes and effects of a total collapse of power system aboard ships and offshore platforms as well as how to mitigate and recover from these major failures. The catastrophic failure of power sources can cause a blackout condition which often creates havoc for a vessel. Various causes of this failure, chaotic effects from these failures and ways to mitigate failures are presented...
