In 2014, GSI acquired CSSC Guangzhou Longxue Shipbuilding Co., Ltd., and renamed CSSC Offshore & Marine Engineering (Group) Company Limited (COMEC). COMEC now operates through three wholly owned subsidiaries: GSI, Huangpu Wenchong, and GSI Yangzhou.

In 2025, GSI merged two smaller yards, adding two more production lines for MR tankers and feeder vessels. GSI is also using one repair dry dock for newbuilding, where 8+4 Suezmax tankers have been contracted and are expected to be built.

GSI maintains three production facilities located in Liwan District, Nansha District of Guangzhou, and Zhongshan City, respectively. The company employs 3,144 full-time staff and works in coordination with approximately 3,223 contractors. GSI’s operations includes newbuild, ship conversion, refitting, and repair services.

The yard historically specialised in chemical and oil product tankers, notably 38,000 DWT, 50,500 DWT, and 51,800 DWT vessels. GSI has now broadened its portfolio to include Offshore Support Vessels (OSVs), Ro / Ro, Ro / Pax, and semisubmersible ships.

Facilities at the original shipyard include three slipways (one 50,000 DWT and two 60,000 DWT), one 60,000 DWT dry dock, and a 1,466m outfitting quay. GSI’s international clientele includes leading European and domestic shipowners, with projects often supported by its inhouse design and research department, capable of handling both concept and production design across a range of vessel types.

To enhance construction capabilities, GSI established block fabrication facilities in Shunde and Zhongshan City, both in Guangdong Province.

In 2012, GSI acquired Guangzhou Longxue Shipbuilding Co., Ltd, located on Longxue Island in Nansha District, adjacent to Hong Kong and Macao. This shipyard spans 2.53 square kilometres and is undergoing a major expansion. As of 2009, its annual production capacity was 2.12 million DWT, with future expansion
expected to bring this figure to 3.5 million DWT.

The Longxue yard commenced production of its first 308,000 DWT VLCC in 2008. It is supported by a dedicated technical centre, and the combined workforce, including sub-contractors, numbers approximately 8,581 personnel.

New construction decisions shape the performance, compliance and commercial value of a vessel for decades. Lloyd’s Register helps owners, operators, charterers and project teams make those decisions with greater clarity, combining trusted classification expertise with practical newbuild advisory support. 

Through LR’s New Construction Guide, clients can access independent shipyard intelligence across North Asia, including China, Korea and Japan. The guide helps compare shipyard capabilities, facilities, track record, vessel specialisms and future-fuel readiness, supporting smarter shipyard selection and earlier project planning.

Beyond the guide, LR provides advisory support across the full newbuild lifecycle. From technical specification development and design review to regulatory impact assessments, alternative fuel studies, energy efficiency, carbon capture readiness, site support and operational preparation, LR helps clients reduce uncertainty before it becomes a cost, a delay, or a risk. 

With global technical authority, local shipyard knowledge and deep maritime expertise, Lloyd’s Register supports future-ready vessels from the earliest concept through to construction and delivery, helping clients build with confidence in an increasingly complex market.
