M/V “SARAH” is a Inspection Maintenance and Repair /
Offshore Construction and Light Well Intervention Vessel,
designed by Ulstein Design AS. The hull form, with the ULSTEIN
X-BOW®, combined with diesel electric propulsion system,
ensures exceptional performances with regard to fuel consumption, sea keeping, station keeping, speed, and cargo capacity.
The main propulsion system comprises two azipull thrusters of
controllable pitch propeller type, each driven by frequency
controlled variable speed electric motor. Two retractable/
swing-up azimuth thrusters and two tunnell side thrusters
forward are installed, ensuring the vessel to obtain the best
station keeping capabilities with ERN 99, 99, 99.
The vessel is equipped, built and certified according to
IMO Class III for Dynamic Positioning.
The vessel is equipped a 150 t offshore crane and a module
handling tower for performing subsea riserless well intervention
services. The MHT system is designed to work in cooperation
with the AHC main hoisting winch, the moon pool doors, and
the horizontal skidding system.
