6 INNOVATIVE CYLINDRICAL DRILLING The innovative Castor Drilling Solution s tower and lifting system represent a REAL EVOLUTION STEP IN THE OFFSHORE DRILLING WORLD, enabling to increase the speed of the drilling activities and the drilling performances. Furthermore the smart integration achieved with the vessel improves the ergonomics and the safety of the operations. A A MAIN ADVANTAGES Minimizing the risk of hazardous falling objects due to tower design. Maintenance-friendly design: all main components are located outside, at drillfloor level. Wide open drillfloor layout ensures full access to drillfloor using rig cranes and provide excellent overview over all operations. Lowered CoG increases the stability of the vessel. Proven structural tower design from offshore windmill industry. Balanced lifting ensures optimal load distribution over the support tower. Tower designed for a max lifting capacity of 1650 sh.ton Multiple lifting wires provide redundancy and safety Low speed winches and large radius sheeves increase the wire operative life. No «slip & cut» B B C D Higher tripping speed (varying from +20/+70% depending on the lifting load) considerably reduces the NPT The compensating system is located under the winch at drillfloor/cellar deck level with a capacity up to 1000 sh.ton C The rectractable system allows the maintenance of all tower components with the deck cranes It enables reduced air draught Optimized hoisting performance based on constant power consumption and power re-generation system Less power required at parity of lifting capacity which allows a significant HPU size reduction Winches are operated by digital hydraulic motors which are proven technology from windmill industry Low speed winches reduce the airborne noise at drillfloor and extend the equipment life High redundancy and flexibility achieved by a variable number of Compensation Cylinders Flexible setup ensures optimal heave compensation characteristics/performance at any drilling or down hole operation with less moving parts and minimum friction losses Easily retractable and interchangeable Compensation Cylinders acting on a balanced sheave house Traditional cylinder AHC system is an integrated part of the compensator design D
