Deep in the South China Sea, steel giants rise through the waves. The Blue Whale 7500 splits waves and lifts the world's first 16 MW tension leg floating wind power platform. From the Bohai Bay to the South China Sea, a fierce battle of extreme lifting spanning thousands of miles of sea has quietly begun in the dual cracks of turbulence and timeliness.

Let the main ships do irreplaceable things

The shortage of ship resources is a hard constraint for crossing three work areas and installing four blocks in a short period of time. The key to breaking the deadlock lies in redefining the responsibility boundaries of the main ship - adding auxiliary ships to fully undertake the pre production processes such as pile head cutting and welding finishing, completely removing the blue whale from auxiliary operations, and allowing it to focus on core lifting. Synchronize the adjustment of the sea going sequence: prioritize the completion of the C-block transition, and assist the ship to use the main ship's navigation gap to return and prepare materials. Off peak construction and interspersed operations to achieve zero gap operation of ships. Essentially, it is a restructuring of the construction value chain - precisely allocating scarce resources to irreplaceable key nodes.

Minimize uncertainty

The plan on paper cannot be put on the sea. The project team will break down the entire process of 332 hours of work item by item, and set clear time standards for anchoring, lifting, and connection, forming an hourly schedule. The on-site command team conducts hourly checks and dynamically adjusts any delays. This precision twists the passive chain of people waiting for ships and boats into an active rhythm of lifting when the tide reaches and withdrawing when the window period is extremely short in the unpredictable sea environment. Refinement is not about formalities, but rather the core means of minimizing uncertainty.

The safety window is the construction window

During the installation phase of the Bozhong 26-6 block, a strong convective wind warning of level 6 or above has suddenly been issued. The project team acted decisively to expedite the process - barge approach, personnel transfer, module placement, rigging removal, windproof reinforcement, and evacuation of all personnel, all in one go. When the strong wind arrived one hour earlier than the forecast, the scene had already been closed and all personnel and equipment were safely evacuated. The next morning, as the wind subsided, the blue whale immediately moved to the next spot. Keywords: offshore construction, resource coordination, fine control

Accurate analysis, proactive planning, and decisive execution - the combination of the three can transform the safety window into a construction window. True safety management is not passive shutdown, but completing all necessary actions before risks arise. The commissioning of the world's first 16 MW tension leg floating wind power platform is a victory in equipment capability and a proof of engineering management capability. The methodology of coordinating the release of scarce resources, implementing hourly plans to eliminate waste, and competing with the heavens for time rather than passively waiting will become the underlying competitiveness for China's offshore energy infrastructure to move towards deeper waters.Editor/Gong Ziwei
