The ship is equipped with 3 generators, rated at 3655KW, 6600V, 400A and 2 retractable thrusters rated at 4500KW, 6600V, 486A. The high power rating of the thrusters in relation to the three generators required that special attention be paid to starting-current and voltage-drop issues. Some of the critical requirements were: a. Limiting the starting current and the voltage drop to acceptable levels. b. Ability to start the thrusters with only two of the three generators running. HRVS-DN 6600V, 4.5MW After comparing the various available starting methods available (including auto-transformer starter, electronic soft starters and variabl frequency drives) it was decided that a Solcon HRVS-DN medium voltage soft starter would offer the optimum solution both technically and financially. Two HRVS-DN soft starters were installed. Starting current is 360% of In and starting time is 12 sec. Voltage drop when starting the thruster with only two generators running is less than 5%. The application was a huge success. motor control is our nature -1- Solcon USA | 724.473.1301 or 727.388.4604 | www.solconusa.com Soft Starters for Main Propulsion in “BC Ferries” C-Class Driving main propulsion Motor ratings: 1200A/11MW/6600V Passenger ferries spend a lot of time manuevering at dock while at the same time, trying to ensure passenger comfort. Soft starters for main-propulsion eliminate the initial torque surge on the shaft as the enormous propeller begins to turn. It also eliminates the voltage drop associated with starting these large motors (minimizing the generating capacity required) and reduces wear and tear on the mechanical system. When designing BC Ferries latest C-Class, the designers were looking for a highly dependable soft starting systems for the main propulsion system - one that would endure continuous performance under some of the most adverse conditions including constant vibration, temperature variations and corrosive ambient conditions. Solcon’s HRVS-DN was chosen for its proven track record in these types of marine applications.

At the Edson Gas Plant, the gas is pumped from underground, re-liquefied and then transported via underground pipes to a distribution station. Due to the harsh environmental conditions (nightly temperatures at the Edson plant easily reach -40°C between November and March), the consulting engineer prescribed the use of soft starters. Since Solcon HRVS-DN soft starters are known for being able to operate in some of the most difficult environments, Solcon was selected for the job. These soft starters, rated at 900 HP, reduce high inrush current on starting and eliminate problematic system wide voltage drops while the motor comes up to full speed.

Cargo pumps circulate liquid natural gas at -170°C. When starting, the initial friction at such temperatures causes difficult starting conditions. The four cargo pumps are soft started by the HRVS-DN, thus eliminating high inrush current and torque surge that could potentially damage these very expensive and critical pump motors. Utilizing a dual-adjust curve, the chiller compressor uses the soft starters same current limit curve to eliminate high inrush current and the resulting voltage drop for ship-wide voltage stability. The motor protection package built into the HRVS-DN ensures protection from any number of potential fault conditions for each of the motors in this unique “multi-start” system.

The consulting engineers were looking for a heavy duty solution that would be suitable for operation in humid and salty air conditions with temperatures as high as 50ºC. They also wanted the latest pump control features. The ultimate solution was Solcon’s HRVSDN, high-end medium voltage soft starter. The HRVS-DN’s pump-control software eliminates the damaging effect of water hammer. Water pipes, joints, check valves and other components are protected from mechanical shock while the built-in motor protection relay provides comprehensive protection to both the motor and the soft starter. 5MW at 4160 (800A) x 2HRVS-DN for water pumps at Electricidad Haina SA, Santo Domingo motor control is our nature -12- Solcon USA | 724.473.1301 or 727.388.4604 | www.solconusa.com Soft Starters for Water Desalination Driving water pumps Motor ratings: 6600V, 400A Desalination Plant, Ashkelon HRVS-DN 6600V / 400 A for 6 desalination pumps This new desalination plant has six enormous pumps (over 3 MW each) driving high pressure sea-water through its filtering system on its route to being drinking water. The soft-starting process must be smooth and stepless due to the sensitive piping system involved in desalinating water.

Supplying water to the city requires many booster pumps operating periodically to keep the water pressure at a suitable level. It was very important to eliminate the high inrush current and start-up torque on every start and to have the ability to soft-stop these pumps to eliminate damaging water hammer that threatens the pipe joints, valves, and instruments with every stop. Solcon soft starters not only soft start and soft stop, but also provide start and stop pump curves that increase the life of both the pumps and the piping infrastructure.

The motor inrush current had to be limited because the factory could not sustain the voltage drop caused by the high inrush when starting direct on line. A Solcon HRVS-DN soft starter with its adjustable starting curves eliminated the high inrush current that was disrupting the power grid. It also eliminated the high starting torque that could have caused damage to the motor/blower shaft. By eliminating this wear and tear on the system, Solcon was able to increase the life expectancy of the entire system. Scrubber blower in the Incitec Pivot fertilizer plant in Queensland, Australia.

The fan was initially designed with a damper over the intake for start up. Starting the fan without a damper caused a very high inrush current at 3.3KV. Over time, the damper malfunctioned and was no longer serviceable. When this happened, the starting inrush current became so high that one of the motor’s rotor bars would crack every few months. The customer installed a Solcon HRVS-DN soft starter at a fraction of cost to repair the damper repair and the associated downtime. The soft starter not only eliminated need for the damper but it eliminated the high inrush current and provided benefits to the mechanical system by eliminating mechanical shock. Over 10 years have passed since this HRVS-DN soft starter was installed and since then, the system has been operating flawlessly. The built in motor protection system provides additional assurance of early detection of any changes in the system, allowing for pre-emptive maintenance to avoid any fuure motor damage.

HRVS-DN 6K These soft starters, rated for 900-1250KW, reduce high inrush current on starting that had otherwise, created system wide voltage drops (on an already challenged utility) while the motors were coming up to speed. Solcon’s state of the art digital technology provides operators with the status of the equipment for preventative maintenance purposes. 4 Liquid Gas Compressors 2 x 1250KW, 6.0KV, 3000RPM 1 x 1000KW, 6.0KV, 3000RPM 1 x 900KW, 6.0KV, 3000RPM motor control is our nature -25- Solcon USA | 724.473.1301 or 727.388.4604 | www.solconusa.com Soft Starters for the Oil & Gas Industry Driving Booster Pumps Motor ratings: 4160V, 800A Enbridge Pipelines, Fort McMurray Alberta, Canada At the Fort McMurray pump station installation, inrush current while starting the 2 new pumps was a potential problem. Enbridge engineers searched for a solution that would eliminate the high inrush current when starting and eliminate related voltage drop issue. The equipment also had to operate in severe environmental conditions allowing for long term, dependable operation and reliability.
