Vessel design house Longitude Engineering has launched its latest design series for platform supply vessels (PSVs) – IMT-Isca – the next generation of the successful IMT 984 G-Class, designed with flexibility and efficiency at its core.

“PSV newbuilding has been very limited since 2015, resulting in a shortage of suitable tonnage to support growing offshore energy plans. Inspired by our proven IMT PSV designs, IMT-Isca is the next-step evolution, reflecting the sustainability of our vessel designs, and focussing on efficiency and low-fuel consumption, whilst meeting contemporary regulations.”

Duncan Grigg, Product Lead for Maritime Design at Longitude

The first design in the series, a DP Class 2 PSV – the IMT-Isca G—Flex – has a deck area of 800 square metres and has capacity for the maximum quantity of Type 2 and 3 cargoes allowed under the OSV Chemical Code. The launch follows early engagement with the market, to ensure a fit-for-purpose design that meets both current and future market requirements.

“Offshore energy operations are continuously under pressure to reduce cost and keep an eye on their carbon footprint. IMT-Isca G-Flex is designed for maximum environmental and cost efficiency, with multiple options in terms of electrical architecture, crew and accommodation arrangements, and thrusters. In short, we have evolved the IMT-984 with the interests of both owners and charterers in mind.”

Continues Grigg

Features of the IMT-Isca series include:

  • Flexible design: multi-thruster and different engine options, multiple accommodation arrangements including for up to 12 passengers
  • Optimised for low-energy consumption: designed for IMO Tier III NOx compliance, optional battery installation and possible usage of HVO or alternative fuel
  • Design with efficiency at its core: the flexibility in design and low-fuel consumption combine to drive lower-cost operations

The vessel type has been designed by vessel design house Longitude Engineering, fused with acquired OSD-IMT’s track-record in PSVs and the marine operational and risk expertise of sister company ABL.

“The IMT 984s which we operated at Swire Pacific – the G-Class – were brilliant vessels, with market-leading efficiency and low fuel consumption. It is exciting to work with the Longitude team on the development of these next-generation designs.”

Capt. Simon Healy, Regional Managing Director for ABL in Asia Pacific

IMT-Isca is named after the Celtic word for floating water and the river Exe – a nod to both the fortitude and flexibility of the design series, and to Longitude’s heartland of Exeter.

Longitude is the engineering and ship design branch of Oslo-listed global consultancy ABL Group ASA.
