Internacional incrível – Conformidade Harmônica para Nove Graneleiros Panamax: Grupo CSL e a Via Marítima dos Grandes Lagos

/

Nine Panamax bulk carriers in the CSL Great Lakes Seaway fleet were found non-compliant with Lloyd’s Register harmonic requirements during routine inspection. VFD-driven loads on each vessel were generating harmonic currents exceeding the limits. Mirus Lineator filters brought all nine vessels into compliance — documented with before/after measurements on representative vessels.

Internacional incrível – A mitigação de harmônicas de serviço marítimo salva um programa de embarcação de serviço offshore

/

An offshore service vessel DC drive system produced voltage notching severe enough to cause control system malfunctions on other vessel systems. The vessel program was at risk of cancellation. A Mirus Lineator filter on the DC drive eliminated the notching — restoring compatibility between the drive and the vessel’s sensitive electronics. Documented with oscilloscope waveforms before and after.

The Marco Polo Cruise Terminal in Saint John required emergency lighting that met new fire and life safety codes for 190,000 annual passengers. An emergency lighting inverter was specified as part of the essential services infrastructure — the case covers selection, integration, and reliability requirements for port terminal power systems.

Energia confiável mantém investigação à tona (Confiável Power Inc.)

Canada’s oldest marine biological station at St. Andrews, NB, pumps seawater with two 100 HP pumps — whose speed and flow rate are controlled by variable frequency drives sensitive to supply quality. The case examines VFD-based pump control and power reliability requirements for continuous marine research operations.

Canadian Forces Base Goose Bay — a NATO training facility and alternate space shuttle emergency landing site — updated aircraft ground support power systems in Hangars 7 e 8. The case covers power quality and reliability requirements for military aviation infrastructure with no tolerance for downtime.

Halifax Stanfield International Airport required a 125 Vdc station battery and charger as part of a continuous substation upgrade. The case examines battery backup specifications for airport substation operation — a critical infrastructure application where DC supply reliability directly affects all protective relaying.
