Shipbuilder Completes Complex Propeller Installation Milestone for Naval Vessel
What happened
A shipyard executed the Tail Shaft Insertion and CPP Blades Fitment of an approximately 81-tonne assembly, which included four 7-tonne CPP blades for a 7-meter diameter propeller. This operation, a major pre-float milestone for FSS-1, was completed ahead of the vessel's scheduled float-out on October 6, 2026. The shipyard developed an in-house methodology to manage the challenge of a tight 400 mm radial clearance between the hull structure and the blade sweep circumference.

Why it matters
The successful execution of this complex operation, which surpassed the shipyard’s earlier 36-tonne propeller installations, reflects the engineering precision of the facility’s Hull, Engineering and Quality Control teams. This achievement supports the modernization goals of the Ministry of Defence.
