PLB C-Master Technical Specifications:
C-Master is a DP3 Derick lay barge equipped with 8 azimuth thrusters of which two middle ones are retractable and the rest located above the ship’s bottom making it the most suitable for shallow waters.
Having as low draft as 4.5 meters and her keel cooling system would add to this advantage. She Produces a total of 200 tons of thrust in her 100% thruster capacity.
Having 3 X 60 tons’ tensions and a 1 X 180 Ton A&R winch is
ideal for pipe laying in the Persian Gulf region. She is having an accommodation fully air-conditioned designed for vigorously humid atmosphere of the Persian Gulf region.
She is most suitable for pipe laying (S-Lay) in water depth of up to 100 meters.
Her spacious deck space along with 1 X 800 Tons and 2 X 33 Tons cranes at sides plus her excellent maneuverability makes her specially suitable for infield works.
