MODEC Next Generation Standardized FPSO Design - M350
Channel: Offshore, Maritime and Energy
Date: 21/05/2023

In 2017, MODEC initiated an in-house program to develop a series of new build hull designs that could be standardized based on the mooring concepts relevant to a particular field. These developments were planned and strategized together with DSIC Shipyard in China, so as to gather all MODEC's relevant FPSO and FSO related new built experience and design an optimized hull which will be easy to build and deliver with shorter duration when compared to customized, project specific FPSO hull designs.

The result of the program was the state-of-the-art, standardized FPSO hull that MODEC branded the M350. The M350 comes in four different variants:

~ the M350i for internal turret mooring,
~ the M350s for spread mooring,
~ the M350e for external turret mooring and
~ the M350y for tower yoke mooring

Key Figures
~ 350 m long, 64 m wide, 33 m molded depth.
~ 2.2 million barrels total cargo storage capacity
~ Suitable for topside weights of up to 50,000 mT
~ 25+ years design life (depending on installation location)
~ 160 people standardized living quarters

Main Features
~ Four design variants based on mooring type
~ Full double hull (i.e. double sides and double bottom)
~ Topsides deck area about 20% larger than standard VLCC
~ Submerged cargo pumping system (2 pumps per tank)
~ Davit launched or free-fall lifeboats
~ Helideck with or without helicopter parking option
~ Designed and built to Shipbuilding Standards
~ Design Approval in Principle from ABS and DNV GL
~ Successfully model tested (spread moored and internal turret version)
~ Jointly developed with Dalian Shipbuilding Industry Co., Ltd. (DSIC)
