Siping Juyuan Hanyang Supported Deepwater Fleet's Equatorial Seismic Operation

A Chinese deepwater geophysical fleet completed a 3D seismic exploration operation in the equatorial waters off West Africa, filling a gap in China's operating record at zero-latitude seas. The operation area was located off Gabon and covered more than 10,000 square kilometers, making it a notable marine 3D seismic exploration project.

Continuous Operation in Hot Equatorial Waters

Because the equator crosses Gabon, sea-area temperatures can reach 40 C, and marine growth creates additional operating challenges for cables, cooling systems, and long-duration vessel work. The Haiyang Shiyou 721 vessel operated continuously at sea for five months and set Chinese geophysical acquisition records for daily and monthly 3D seismic output.

Central Cooler Equipment Support

The deepwater geophysical fleet consisted of the Haiyang Shiyou 720 and Haiyang Shiyou 721 vessels. Siping Juyuan Hanyang Plate Heat Exchanger Co., Ltd. supplied equipment for the related twelve-cable geophysical vessels in 2009 and 2013, including main central coolers and auxiliary central coolers, supporting the vessels' cooling systems during continuous operation.

Marine Heat Exchange Experience

Siping Juyuan Hanyang Plate Heat Exchanger Co., Ltd. has long focused on marine heat exchange applications. Its equipment can be used as central coolers, lubricating oil coolers, fresh-water coolers, and hydraulic oil coolers across tankers, LNG carriers, container ships, bulk carriers, engineering vessels, chemical tankers, asphalt carriers, deck carriers, supply vessels, and sulfur carriers.

The company said technical capability and quality assurance are key reasons marine customers select its heat exchange equipment. This case also shows the value of plate heat exchangers in marine engineering, vessel power systems, and continuous-operation cooling systems.
