ERHA and USAN FPSOs (ExxonMobil)

Premier Ship Models were recently contracted with a rather complex order of two large Erha FPSO models, as well as one large Usan FPSO model, together with thirty smaller models of each, to be completed for a private foreign company.

All three large models were to be at a scale of 1/300, with the two Erha’s measuring 95 centimetres in length, with the Usan being slightly larger, at 107 centimetres in length. We also provided a custom-built display case for each model, to ensure their protection and retain their ability to be displayed over an extended period of time! They all received Esso embroidered stands for added flair.

The thirty smaller models of each all measured 30 centimetres in length, and were complete with stands and informational plaques.

An FPSO is a vessel, the acronym stands for Floating Production Storage and Offloading, and both the real-life Erha and Usan are two of the world’s largest and foremost FPSO’s.

The Erha has a designed storage capacity of 2.2 million barrels of crude oil, with a remarkable processing capacity of 210,000 barrels a day! It is operated by Esso Exploration and Production Nigeria (EEPNL), which is a subsidiary of ExxonMobil.

The Usan has a slightly lesser production capacity of 180,000 barrels a day, but is still vastly successful.

The project was completed for a private client based in Nigeria. They partner with various investment firms in order to source and structure investment opportunities, and they largely focus on the US market, but also work all around the globe.

All of the models were originally produced using 3D printing technology and then meticulously finished by hand.

Each one was constructed entirely from wood and fibreglass, with chrome detailing applied to smaller sections to enhance the overall appearance.

3D printing is a highly specialised craft that relies on a thorough understanding of three key factors:

• The properties of the materials used
• The operation and capabilities of the printer
• The design objectives and intended final outcome

This process demands considerable expertise. Our 3D printing specialist manages two principal stages: firstly, the creation and preparation of the digital model for printing; and secondly, the refinement of the printed components to achieve a high-quality, professional finish.

The bespoke Erha and Usan models were primarily 3D printed using timber, fibreglass, and acrylic, and finished with chrome accents — reflecting a high level of technical skill, technological sophistication, and precision.

Before construction began, every detail was carefully reviewed and agreed with the client. This included precise measurements, design specifications, aesthetic preferences, the payment schedule, and the overall project timeline. Establishing clear terms from the outset ensured a smooth process and significantly reduced the risk of misunderstandings.

The build commenced with the bases, which formed the structural foundation of the models. This phase required meticulous measurement and exceptional craftsmanship to accurately capture the structure’s original form. With the bases completed, work progressed to the upper sections — including pipes, valves, and cranes — to achieve the highest possible degree of realism.

The painting stage was undertaken with great care to achieve a flawless, high-quality finish. The bases were painted a crisp black, while the majority of the models were finished in Esso’s classic blue, red, and yellow. In the final stages, each model was thoroughly cleaned and polished to perfection.

The client expressed great satisfaction with the final outcome. Delivering a project of this calibre required significant attention to detail and collective effort, and we take great pride in the professionalism demonstrated throughout. With this commission successfully completed, our focus now shifts to the ongoing and forthcoming projects in our portfolio.
