Installation and Maintenance of Offshore Facilities and Equipment

Installation and Maintenance of Offshore Facilities and Equipment:

Haiyi holds the “Offshore Equipment Maintenance Qualification Certificate” issued by CNOOC and maintains a highly experienced team specializing in the installation and maintenance of offshore facilities and equipment. The team boasts a full range of technical specialties and comprehensive certification, enabling it to provide engineering services—including skid‑mounted equipment, installation, and maintenance—for various types of offshore assets, such as drilling rigs, vessels, FPSOs, and terminals.

Example 1 ：

In April 2023, Haiyi installed multiple sets of domestic wastewater treatment systems on drilling platforms for CNOOC Services and other clients.

The existing domestic wastewater treatment system on the drilling platform no longer meets current discharge standards, necessitating its removal and the installation of a compliant treatment unit (model: CSWD-70). Following an on-site assessment and taking into account the platform’s limited space and the dense arrangement of surrounding equipment, Haiyi Company carefully planned the placement of the treatment system and the routing of associated pipelines. Without compromising the operation of adjacent facilities, they successfully completed installation and commissioning, achieving both quality and schedule compliance, and securing acceptance by the platform operator.

Example 2:

Haiyi specializes in providing one-stop ship repair and maintenance services for vessels of all types and offshore facilities, boasting mature on‑site repair capabilities and a comprehensive service system. With a team of highly skilled professionals and extensive offshore operational experience, we offer full‑range services—including emergency repairs during voyages, routine preventive maintenance, equipment overhauls, and component restoration—for both underway and at‑dock vessels. We also cover inspection, maintenance, and repair projects for various offshore platforms and associated infrastructure.

Repair Case:

HYSY201 Ship Repair Project: The project encompasses a wide range of maintenance and modification tasks, including crane repair and maintenance, relocation and overhaul of mooring winches, renovation of logistics and living facilities, repair of marine electronic components, fabrication of custom‑made parts, and optimization of the ship’s lighting system. In total, more than 30 specialized operations have been completed. Throughout the project, work was carried out in strict compliance with industry standards, ensuring high quality and timely delivery, thereby fully demonstrating the company’s comprehensive expertise in ship repair, marine equipment maintenance, offshore facility upgrades, and component fabrication and repair.
