The pile driving barge is equipped with an extra‑tall 72‑metre pile leader designed for marine and offshore foundation works. This leader height allows the vessel to handle very long tubular steel piles and H‑piles for deep‑water projects, bridge foundations, and large quay walls, reducing the need for splicing and increasing overall installation efficiency.The 72 m leader is a lattice‑type steel structure with high bending stiffness and torsional resistance. It is engineered to withstand dynamic loads generated by impact and vibratory hammers during pile driving operations. The leader provides accurate vertical or raked alignment of the pile, ensuring that design tolerances for position and inclination are maintained even under challenging sea and weather conditions. Adjustable guides and clamp systems are fitted along the length of the leader to secure the pile and minimize deflection.The barge itself is configured as a stable work platform with sufficient deck space and load capacity to support heavy lifting equipment, hammers, power packs, and ancillary tools. A main crane or dedicated pile handling system is used to upend, lift, and position piles within the leader. Once the pile is correctly aligned, the hammer—diesel, hydraulic, or vibratory—is mounted at the top of the pile and operated from a central control station. Instrumentation for blow count, penetration rate, hammer energy, and pile inclination can be integrated for real‑time monitoring and quality control.The 72 m leader height offers distinct advantages for offshore wind, deep berthing facilities, and river or sea‑crossing bridge projects, where pile lengths frequently exceed conventional leader capacities. By accommodating longer single‑piece piles, it reduces welding time, joint preparation, and inspection work offshore. This not only shortens construction schedules but also lowers risks associated with working over water and at height. In addition, fewer pile joints improve structural continuity and fatigue performance, which is important for long‑life marine structures.For safe and efficient operation, the pile driving barge is equipped with a positioning and mooring system suitable for the water depth and environmental conditions at the site. Spud legs or a mooring spread are commonly used to maintain the barge’s position during driving. Safety features include access ladders, work platforms along the leader, fall‑protection systems, and emergency stop devices for all major equipment.Overall, the 72 m pile leader height on the pile driving barge significantly extends the operational envelope for marine piling, enabling the installation of very long foundation elements with high precision, improved productivity, and enhanced structural reliability in demanding offshore and nearshore environments.
