Description

Technical Field

[0001] The present invention belongs to the technical field of front and side thrust installation, and in particular relates to a PCTC front and side thrust installation device and method. Background Art

[0002] Bow thruster is an auxiliary seakeeping device for modern ships, mainly used to help ships quickly adjust their direction in emergency situations to avoid collisions. It is usually installed on bulk carriers with larger tonnage, and consists of a propeller and a power unit installed at the bow. It can provide additional thrust in emergency situations to help ships quickly adjust their direction.

[0003] The bow thruster is mainly composed of a propeller and a power unit. The thrust generated by the propeller is perpendicular to the hull, so that the bow of the ship can quickly respond to direction adjustments. The bow thruster has a compact structure, but requires a dedicated hydraulic oil supply and operating system. The electric device usually requires a pair of bevel gear reductions, and the motor must be installed above the waterline.

[0004] To ensure safety and performance, the bow thruster is usually installed behind the bow collision bulkhead, and avoid being installed too close to the bow and stern. The distance between the guide cylinder axis and the keel and load waterline should be kept at one cylinder diameter to prevent air from being sucked in due to wind and waves and hull movement.

[0005] The PCTC bow lateral thruster is of tube-tunnel type, which is relatively difficult to install after the hull structure is complete. How to install the thruster without damaging the hull structure is a technical problem that needs to be solved urgently. Summary of the invention
