London-based design and engineering consultancy Longitude has launched a compact \u201cD-Flex\u201d platform supply vessel (PSV) design \u2013 the second design in its IMT Isca series<\/a>, introduced in 2024.<\/p>\n Longitude says that the D-Flex design is an evolution of its operationally proven IMT 984 (G-Class) design and is a smaller, cost-efficient addition to the series for shipowners that seek long term economic value.<\/p>\n \u201cWe believe that the success of a ship and its design hinges simply around one question \u2013 does it make money for its owner? By targeting low CAPEX and OPEX within a package attractive to charterers, the D-Flex design offers shipowners an alternative where larger PSVs are not appropriate,\u201d says Duncan Grigg, Longitude\u2019s product lead for maritime design.<\/p>\n The D Flex is designed as a compact PSV tailored for offshore energy operations in Asia, the Middle East, and West Africa, with additional potential for deployment in the Southern North Sea.<\/p>\n The DP Class 2 vessel is 74.7 meters long, 16.2 meters wide, and has a deadweight of 3,000 tonnes.<\/p>\n Despite its smaller size, says Longitude, the design offers the same strong adaptability as the series\u2019 G Flex, with wide scope for owner-configured layouts. This includes alternative accommodation and powering configurations, and optional preparation for future alternative fuel options such as methanol. The vessel has a total deck area of 650 square meters.<\/p>\n Generous accommodation capacity ensures suitability across multiple geographies and crewing models, while flexibility around the maker\u2019s list allows owners to align the vessel with preferred equipment or lifecycle strategies.<\/p>\n \u201cOur approach is simple: A PSV should earn its keep. By combining operational insight with robust naval architecture, the D-Flex is engineered to reduce cost and complexity for owners without compromising capability. It is a design shaped by real-world operations, not just theory,\u201d Grigg adds.<\/p>\n The D-Flex is the second design of Longitude\u2019s IMT Isca series, which represents the next generation of PSVs, evolved from the successful IMT-984 series, and designed with the flexibility to adapt to the specific commercial and operational requirements of owners.<\/p>\n The IMT Isca line focuses on sustainability for the owner, both economically and environmentally, while meeting regulatory requirements:<\/p>\n The design series offers wide ranging flexibility across cargo configurations, accommodation layouts, machinery arrangements, and propulsion options, enabling owners to tailor the vessel to mission and market.<\/p>\n Based on a proven low fuel consumption platform, the vessels can be adapted for alternative fuel configurations, including Tier III NOx compliant options.<\/p>\n Longitude, which is part of Oslo-listed ABL Group, ASA,<\/a> specializes in ship design, marine operations, facilities and subsea and offshore wind design, with offices in more than 15 countries around the world.<\/p>\n The post Longitude launches new compact D-Flex PSV design<\/a> appeared first on Marine Log<\/a>.<\/p>\n<\/div>\n
