Liquid tank loading onto ship
Recently, Nantong CIMC Pacific Offshore Engineering Co., Ltd. has achieved continuous successes and fruitful results in the LNG clean energy marine engineering equipment赛道. From the delivery of ultra-long LNG bi-lobe tanks, the delivery of fuel tanks for high-end luxury cruise ships, to the completion of large Type B LNG fuel tanks, the company has successfully fulfilled the milestones of three major key projects, continuously demonstrating its hardcore technical strength, high-end manufacturing level, and stable performance capability in the field of marine clean energy equipment.
4600m³ ultra-long bi-lobe tank successfully shipped
The 4600m³ ultra-long bi-lobe tank is the first project for /Intercontinental Shipping. The liquid tank is an independent Type C, adopting a bi-lobe tank design with a total length of 56 meters. Its length far exceeds conventional LNG fuel tanks, making it a typical ultra-long tank, which imposes extremely high requirements on construction processes, precision control, site turnover, lifting, and shipping. This series of projects is an important achievement of CIMC Pacific Offshore’s continuous deep cultivation in the field of ultra-long bi-lobe tanks.
During the project construction, the tight schedule was the biggest challenge faced by the team. Facing the urgent delivery deadline, the project team coordinated and integrated departments including design, procurement, safety, quality, and production, working closely and collaboratively. Ultimately, all work including tank construction, equipment installation, pressure testing, and completion acceptance was completed with high quality within the scheduled工期, ensuring on-time delivery with guaranteed quality.

Delivery of 2000m³ LNG fuel tank for luxury cruise ship
This project is classed with DNV. The design is a horizontal bi-lobe tank, commissioned by the globally renowned liquid cargo system supplier Wärtsilä, and will serve as core equipment for the Carnival series luxury cruise ships.
The project officially started in May 2025. After one year of meticulous and refined construction, it was completed and delivered on schedule as planned. During the construction, the CIMC Pacific Offshore project team faced a series of challenges, such as the narrow space of the enclosed cabin and the high integration of internal piping systems, all of which imposed extremely high requirements on design precision, manufacturing processes, and on-site construction management. Facing numerous technical and construction difficulties, the team adhered to the craftsmanship spirit of continuous improvement, strictly controlled the entire process from scheme design, manufacturing, quality inspection, to testing and verification, overcoming various challenges with professional technical capabilities and a rigorous management system. At the same time, the team maintained efficient coordination and close interaction with the customer, precisely meeting various requirements, ultimately ensuring the orderly implementation and timely completion of key project milestones.

First set of 7500m³ LNG Type B fuel tank successfully completed and delivered
This project, as CIMC Pacific Offshore’s first 7500 cubic meter LNG Type B fuel tank, has been officially delivered to Hudong-Zhonghua Shipbuilding (Group) Co., Ltd., and will subsequently be used for 9000TEU dual-fuel container ships.
The fuel tank delivered this time is the core key equipment of the ship’s dual-fuel power system. It possesses core advantages such as low-temperature cold insulation, structural safety, and efficient storage and transportation. It is a mainstream supporting product for ocean-going vessels to practice low-carbon emission reduction and comply with new international shipping environmental regulations. This series of projects totals 7 ship sets, with a single 7500m³ large-capacity Type B fuel tank configured per ship. The design detailing, material procurement, and construction were all independently undertaken and completed by CIMC Pacific Offshore.
From the start of the project, it faced multiple superimposed pressures, making the delivery task very严峻. On one hand, the customer requested a compressed construction period, advancing the overall delivery cycle by a full month compared to the original plan. On the other hand, due to drawing changes and the high standards and requirements of the shipowner, cross-conflicts between various processes increased, and resource coordination became significantly more difficult.

Facing a series of difficulties, the project team actively coordinated multiple disciplines including design, materials, safety & environment, quality inspection, and production. They organized multiple rounds of special technical discussions, comprehensively reviewed construction difficulties, and optimized core process plans for block construction, insulation work, pipe pre-installation, grinding, and cleaning. Relying on the mature system of LNG low-temperature equipment accumulated over many years, the team overcame a series of construction technical challenges one by one, including assembly block turning fixtures, insulation waterproofing, large tank precision control, equipment installation protection, and ship loading stowage. At the same time, they scientifically planned multi-disciplinary交叉 parallel construction schemes. Through refined project management involving pre-planning, dynamic coordination, and daily progress review, they maximized the capacity utilization of site, equipment, and manpower. All project participants united and worked day and night. Under the premise of strictly adhering to safety production red lines and strictly controlling product manufacturing quality, the project was completed and delivered on schedule, fully meeting standards in the three dimensions of safety, quality, and construction period.

The successful delivery of this project not only accumulated standardized construction experience for the subsequent batch production and delivery of the same series of 6 ship sets of LNG fuel tanks for both parties, but also centrally demonstrated the excellent and pragmatic work style of the CIMC Pacific Offshore technical team in overcoming difficulties, independent innovation, continuous improvement, and fulfilling responsibilities. It is another comprehensive practical verification of CIMC Pacific Offshore’s comprehensive strength in the field of clean energy ship supporting equipment.
Based on a new milestone, moving towards a new journey. In the future, CIMC Pacific Offshore will continue to deeply cultivate the core赛道 of LNG storage and transportation equipment, continuously optimize technical solutions and construction processes for various types of marine low-temperature fuel tanks, and with higher manufacturing standards, better quality products, and stronger performance capabilities, continuously empower the green, low-carbon, and high-quality development of the global shipping industry!
