The MOLEC Electrical team have now finished the installation at HMAS Cerberus. At HMAS Cerberus we were required to build a new training simulator within existing Commonwealth facilities that enables the Royal Australian Navy to train their personnel on a ships diesel generation and electrical distribution system. MOLEC took this project on as a Design and Construct Contract and was required to emulate a RAN ship installation and as such comply with DEF(AUST) 5000-VOL 05 Pt 08 – Electrical System Requirements- Electrical Systems for RAN Combatant Ships and Submarines. To achieve this, MOLEC assembled a specialised team of recognised experts in their individual fields and have overseen the complete design and installation of the electrical system, fuel system, water coolant system, airflow and exhaust system and also a raised platform area to allow for ease of access to the generators for training purposes.

For the construction of the simulator we used five marine grade Kohler/ MTU diesel generator sets operated via three main switch boards. Load is simulated for training purposes using two Sepcho WAR series load banks, which are both resistive and reactive power.

The complete system can be controlled either manually via the control panels on the front of the MSB’s or automatically via the Human Interface Panel on each MSB or remotely over a network.

During March/April 2014 Molec Electrical Contractors has been involved in creating a power generation and distribution system intended for training environments for sailors in the Royal Australian Navy. This simulator will allow the sailors to familiarize themselves with the technology that they will be expected to use aboard ship.

The electrical system is designed for a split plant, split parallel and closed-loop ring mode operation that replicates a ship’s electrical supply and distribution system. It consists of the following major items:
Ø Four 440 Volt, 60 Hz, 3 phase diesel generators, approximately 50KVA capacity to
replicate ships generation plant.

Ø One 440 Volt, 60 Hz, 3 phase diesel generator, approximately 50KVA capacity to
replicate shore supply generation plant..
Ø Two Main Switch Boards (MSB),
Ø One Shore Power Switchboard (SPS),
Ø Four electric motors (440 Volt, 3 phase, approx 2 HP) including control equipment,
Ø Two Electrical Distribution Centres (EDC),

Ø Minimum six Distribution Panels,
Ø Two Variable Load Banks , and
Ø Two power connection points to simulate Ship power connection points
Ø Two power connection points to simulate Shore power connection points.

During March 2012, Molec Electrical Contractors were involved in the electrical upgrade to the Silo Electrical Services to comply with current standards for Goodman Fielder - Pampas.

The requirement of this project was to inspect the existing installation and formulate a turnkey solution to upgrade the designated plant to comply with current legislation while the facility remained in full production and preserving the protocols required to operate in a food preparation environment.

This installation works consisted with mainly all Steel Wire Armour and Intrinsically Safe cables for use in Hazardous Dust environments classified as Zone21 and Zone22 and integrating 24Vdc equipment with an existing PLC which operated on a 240Vac system.

Works also included the installation of pneumatic actuators in the classified hazardous areas in lieu of non-compliant electrically operated actuators and valves.

Part of these works included developing a plan to facilitate working at heights over shared trafficable areas requiring the passage of delivery vehicles in order to keep the plant in full production.

Australian Federal Police - Weston Data Centre Canberra - Emergency Generator Installation

Molec performed the following work on this project on behalf of Coote Energy:

Ø Complete rewiring and additional modifications on a double-bus 415V, 2000A switchboard for controlling four 630A essential data-centre load circuits, a bus-tie, a 400kW load bank, and two Cummins 650kVA containerised (outdoor) generator sets, with provision for a third generator set. The switchboard contained automatic ComAp controllers for selecting either the mains supply or generators for powering the four load circuits.

Ø Most of the 2000A copper busbar was removed for cleaning due to tarnishing through a sulphuric acid spill at the place of manufacture of the switchboard.

Ø Modifications were performed to the generator on-board controls to facilitate interfacing with the controllers in the double-bus switchboard.

Ø An outdoor control box was built and installed for a 10kL automatic bulk refuelling system for filling the generator 900L onboard tanks from the bulk tank.

Ø A new metering switchboard (between the ActewAGL substation and double-bus switchboard) was installed to replace an existing metering board, performed in a single day as part of an extensive cutover plan for the essential load circuits between an original switchboard and the new double-bus switchboard.

Ø Assistance was provided with commissioning the installation up to the point of final cutover.
