Ulstein, a Norwegian shipbuilder and ship designer, has unveiled a new subsea vessel, the ULSTEIN SX232, tailored to serve the offshore wind market for both floating and fixed installations, as well as the offshore oil and gas industry, says an article published on marine link website.

Summary

  • Ulstein, a Norwegian shipbuilder and designer, introduces the ULSTEIN SX232, a new subsea vessel catering to the offshore wind and oil/gas industries.
  • The vessel features an optimized hull design based on the ULSTEIN TWIN X-STERN, ensuring superior performance in challenging maritime conditions.
  • Equipped with a smart power and propulsion system, the ULSTEIN SX232 aims to minimize energy consumption during dynamic positioning (DP) operations and utilizes waste heat for emission reduction and cost savings.
  • It offers improved performance, safety, and comfort, with versatile fuel options and a battery energy storage system for operational flexibility.
  • The vessel’s layout includes accommodation for up to 130 personnel, ROV hangars, a moonpool for subsea operations, and a spacious flat deck for various operational setups.

Design Features

The ULSTEIN SX232 is specifically designed for walk-to-work operations in the offshore energy sector. It boasts an optimized hull based on the ULSTEIN TWIN X-STERN design, ensuring superior performance in challenging maritime conditions.

Smart Power And Propulsion System

Equipped with a smart power and propulsion system, the vessel aims to minimize energy consumption during dynamic positioning (DP) operations. Additionally, an integrated energy recovery system efficiently utilizes waste heat from machinery systems, contributing to emission reduction and operational cost savings.

Enhanced Capabilities

Ulstein emphasizes that the ULSTEIN SX232 offers improved performance, safety, and comfort. The vessel’s design incorporates versatile fuel options and includes a battery energy storage system for peak shaving and spinning reserve purposes, enhancing its operational flexibility.

Functional Layout

The forward section of the vessel accommodates up to 130 personnel and features two remotely operated vehicle (ROV) hangars. At the rear of the accommodation block, a moonpool facilitates subsea operations, complemented by a spacious flat deck spanning over 2,000 m². This design versatility allows for various operational setups to meet diverse maritime requirements.

Crane Capacity And Applications

Initially configured with a 250-tonne offshore crane, the ULSTEIN SX232 platform can support an upgraded crane capacity of 400 tonnes. This enhancement enables the vessel to handle tasks such as the installation of suction anchors, commonly used in floating offshore energy projects. Additionally, the vessel can be utilized for inter-array cable laying operations.

Market Demand And Versatility

Ulstein underscores the growing demand for subsea vessels capable of operating in challenging environments and performing complex tasks. Whether supporting offshore wind farms, oil and gas platforms, or other maritime operations, the ULSTEIN SX232 aims to offer flexibility, efficiency, and reliability to meet evolving industry needs.
