China’s rigid pipelay fleet ranks 1st in Asia-Pacific and 3rd globally. Its DP3 vessels excel in deepwater operations and operate worldwide, while DP2 and non-DP vessels serve mid-deep and shallow waters respectively. Unlike wind farm installation vessels, top-tier pipelay assets have solid market prospects with no major overcapacity risks.

This document summarizes most of China Classification Society (CCS) classed full-revolving floating cranes in China as of 2026, categorized by dynamic positioning (DP) level: DP3, DP2, DP1, and non-DP. The fleet shows a highly unbalanced distribution between South and North China, with over 70% operating in southern waters. Several vessels are working overseas in the Middle East and Southeast Asia, reflecting growing Chinese participation in international offshore wind, oil & gas, and heavy-lift markets. Newbuild deliveries since 2022 are substantial, indicating potential oversupply and intensified competition ahead.

This is GAC Announcement No. 9 of 2026, effective February 1, 2026, regulating export declaration for dredgers and similar vessels.

Zhenjiang Seagoing Vessel Anchorage launches maintenance dredging in 2026 with a total construction period of 125 days, to be completed by late November 2026. Zonal and time-phased construction is adopted; no works during the flood season. Non-construction vessels are prohibited from entering the construction zone. All passing ships shall slow down, keep safe distance and follow on-site commands.

This report analyzes the 2025 global tugboat delivery market using S&P Maritime Portal data covering 1,067 vessels. The market is dominated by standard tugboats, with engines led by Yanmar and Mitsubishi. Construction is concentrated in Southeast Asia, especially Indonesia. Most tugboats are in the 1000–2000KW power range, and the top shipyard is Karya Teknik Utama. The industry shows high regional concentration, specialization, and growing demand for eco-friendly tugboats.

This paper analyzes seven typical accidents of offshore engineering vessels, including crane failure, sinking, suffocation, explosion, and collapse. It summarizes high-risk characteristics such as complex equipment, mixed personnel, environmental sensitivity, and frequent confined space operations. Ten safety measures and a four-level graded emergency management system are proposed to prevent disasters. The conclusion emphasizes strict corporate responsibility, standardized confined space operations, enhanced safety redundancy, and strict vessel inspection to fundamentally avoid casualties and major losses.

Abstract: This news announces the start of construction of a deep-water crane vessel designed by MARIC (708 Institute) with a cost exceeding 1.1 billion yuan (contract value 1.1488 billion yuan). The vessel is built by Shanghai Zhenhua Heavy Industries for Guangzhou Salvage Bureau, featuring 142-meter pile legs, 90-meter water-depth operation, 210-meter lifting height, and 1600-tonne leg-encircling crane. With full electric propulsion and DP2 dynamic positioning, it serves multi-purpose tasks including emergency salvage, offshore wind installation, platform maintenance and living support. The vessel will strengthen China’s offshore emergency response and marine engineering capacity.

This report analyzes China’s deck barge market from 2024 to 2025, focusing on the 5,000 DWT aft-steered deck barge with ramp — the most popular and liquid type. Newbuilding prices range RMB 28–41 million, while secondhand prices decline with age (RMB 5.8–24 million). Daily charter rates are RMB 21,000–27,000, with secondhand assets offering faster payback. Strong demand comes from domestic and overseas infrastructure, especially Southeast Asia. The market is booming with growing momentum toward larger tonnages and offshore wind specialized vessels.

This report analyzes the global grab dredger market with a focus on real market structure: large state-owned dredging companies pursue high-end, green, and intelligent technologies; private shipowners mainly replace old vessels with larger ones; emerging markets still rely on traditional and non-self-propelled dredgers. High-end, green, and intelligent trends apply only to top players, while upscaling and practicality represent the real mainstream.

This news introduces CRCC Piling No.1, the world’s tallest pile frame pile driving vessel, officially delivered in Nantong on March 31. The vessel sets three world records: 156-meter pile leader frame, 700-ton maximum pile weight, and over 70-meter operating water depth. It is China’s first large piling vessel equipped with a DP system, featuring centimeter-level positioning accuracy and unlimited navigation area. It applies two globally pioneering technologies: integrated DP + mooring positioning system and main cylinder closed-loop hydraulic energy recovery system. Fitted with a world’s largest 5000-ton opening-closing hydraulic cylinder and green emission systems, the vessel will support global offshore wind power, cross-sea bridge, and deep-sea engineering projects, starting with the Salvador Bridge in Brazil.

By the end of 2025, CCCC Dredging owns the world’s largest and most technologically advanced dredging fleet. In 2025, the company optimized its fleet structure by launching new high-end dredgers, phasing out old inefficient vessels, and improving operation efficiency. Key new equipment includes 35,000m³ large trailing suction hopper dredgers, the world’s largest fully electric detachable environmental cutter suction dredger, and intelligent eco-dredgers. Technological breakthroughs were made in alpine shield machines, domestic core components, and AI-assisted construction. CCCC Dredging will continue to lead the industry with large-scale, green, and intelligent development.
