Cheoy Lee Delivered 3 Major Projects in May

Jun 13, 2007

The 36m (118’) Crew Boat ‘Pertama’, delivered on May 5, completed it’s delivery voyage to Brunei in just 4-days, and is now entering service. Twin Caterpillar 3508B engines propel the steel hulled/GRP superstructure vessel to a speed of 17knots.

Departing two days later on May 7, Cheoy Lee’s 16th ‘Z-Tech 6000’ 5,000HP tug set sail for Singapore to join the growing PSA Marine fleet. Cheoy Lee is scheduled to complete one ‘Z-Tech 6000’ tug per month over the next year, for Panamanian, Singaporean and Australian clients.

The third recent delivery was a ‘50m (164’) Off-take Support Vessel’ built to Bureau Veritas 1 + HULL + MACHINERY + AUT/UMS + CLEAN-AIR TUG SUPPLY VESSEL UNRESTRICTED NAVIGATION. The 1,200 tonne vessel, designed in Singapore, and built for a repeat client in Australia is powered by an electric drive propulsion system. The twin electric motors are energized by three Caterpillar 3516B generating sets each producing 1,825kW(2,450 HP). The two 1,825kW Siemens electric motors drive two Schottel SRP-1515 Azimuthing thrusters. Two 2.6m (8.5’) diameter propellers are housed inside the steerable nozzles. Maneuvering is enhanced by a 550kW Schottel STT2 electric bow thruster. Power from the three Caterpillar generating sets also powers onboard electrical equipment.


Deck machinery includes towing winches fore and aft. The aft double drum winch, also used for anchor handling, has a capacity of 75 tonnes at 15m (50’)/minute and will hold 2 x 1000m (3,300’) lengths of 52mm (2”) diameter wire rope. The wood sheathed aft deck also includes a 20 tonne tugger winch, two hydraulically activated towing pins and a 3m (10’) stern roller.
