Project Summary

Project
Incat Crowther collaborated with Bhagwan Marine and Neptune Marine Services on this AUD 30 million project in Dampier, Australia, to develop a first-of-a-kind, integrated catamaran. The goal was to design one vessel capable of performing six functions: dive support, geophysical survey, geotechnical survey, cargo transport, hyperbaric rescue, and safety standby. Challenges included SOLAS 2009 (Safety of Life at Sea) compliance, efficient space arrangement, and displacement and draught control.

Solution
With such a varied array of operational roles, this project required unique solutions not only in the allocation of compartments and spaces, but also with the specification of a flexible, high-redundancy propulsion system. Numerous arrangement prototypes were analyzed based on 3D hull-form and compartment configurations developed in Bentley’s MAXURF software. This allowed the team to select the optimal arrangement with the highest operational safety while enabling performance of all intended roles.

Outcome
Using the MAXSURF software, particularly MAXSURF Stability Enterprise, the time required to accurately determine the stability characteristics of the vessel was reduced from a projected three months to one month. The software allowed the team to quickly identify innovative solutions, automate the required analyses, and integrate SOLAS regulation compliance into the design. Capital costs were also reduced.

Software
MAXSURF Modeler and MAXSURF Stability Enterprise were integrated into the design process to determine the overall intact and damage stability of the vessel, which enabled the team to develop 3D models of various hull-form and compartment configurations.
Outcome/Facts:
  • Using MAXSURF, the time required to accurately determine the stability characteristics of the vessel was reduced from a projected three months to one month.
  • The team’s innovative design reallocated compartments and respecified the flexible, high-redundancy propulsion system
  • What sets this vessel apart from its peers currently operating in similar environments is the combination of six capabilities consolidated onto a singular purpose-built platform.
