Longitude Engineering has launched D-Flex, a compact platform supply vessel (PSV) design positioned as the second entry in its IMT Isca series. The company says the design is an evolution of the operationally proven IMT 984 (G-Class) and targets long-term economic value for shipowners.

Configured as a DP Class 2 PSV, D-Flex is intended for offshore energy operations in Asia, the Middle East and West Africa, with additional potential deployment in the Southern North Sea. The design measures 74.7 m in length and 16.2 m in breadth, with a deadweight of 3,000 tonnes.

Longitude Engineering states that the vessel provides scope for owner-configured layouts, including alternative accommodation and powering configurations, as well as optional preparation for future alternative fuels such as methanol. Total deck area is stated at 650 m². The company adds that accommodation capacity is designed to support multiple geographies and crewing models, while flexibility around the maker’s list allows owners to align the vessel with preferred equipment or lifecycle strategies.

The wider IMT Isca series is described as the next generation of PSVs, evolved from the IMT-984 line and developed to adapt to specific commercial and operational requirements. Longitude Engineering says the series focuses on sustainability for owners, economically and environmentally, and can be adapted for alternative fuel configurations, including Tier III NOx compliant options. The company is part of ABL Group.
