HS-SOSS PERSEAS — Accommodation Expansion & Conversion Feasibility

Comprehensive feasibility study to expand accommodation from 70 to 235 personnel and integrate small-craft launch/recovery systems on the Hellenic Navy support vessel (A377).


The study addressed the need for increased accommodation capacity while maintaining operational efficiency and vessel functionality — focusing on layout reconfiguration, auxiliary spaces and mission-support systems with minimal impact on existing hull structures. The work established the basis for a potential full vessel conversion.

Scope of Work

Coordinated and supervised multiple critical mechanical and marine systems refurbishment activities, including:

  • Accommodation redesign — +165 personnel
  • Small craft launch & recovery system (4 SAP + 8 ZODIAC)
  • Structural & mechanical modification studies
  • HVAC, water, sewage, power and lighting upgrade assessments
  • Stability + weight management studies
  • Preliminary cost and duration estimation

Our Approach

HYDRUS delivered the complete feasibility assessment for the conversion concept — including accommodation redesign studies, launch-and-recovery system assessment for 4 SAP boats and 8 ZODIAC craft, structural and mechanical modification studies, evaluation of onboard utility systems, and preliminary cost / duration estimation for the full conversion scope.
