Stability Analysis

Bastion Defence Consulting provides full stability analysis against stability standards as well as recommendations for remediation action required for vessels with compromised stability. Bastion’s Naval Architects have experience in creating full 3D ship models for intact and damage stability as well as calculations for compliance to various conventions including Load Line, SOLAS, Suez/Panama Canal Certificates.

Bastion Defence Consulting Naval Architects have experience remodelling vessels to account for design changes that modify the stability characteristics of the vessel using many different stability modelling tools.

Inclining Experiments

Bastion Defence Consulting have extensive experience conducting inclining experiments on many classes of commercial and military vessels including submerged and surfaced submarine trials and inclining experiments of surface ships up to Destroyer size. Our Naval Architecture team has also significant experience in writing and updating stability booklets post inclining experiments.

Margins Management

Bastion Defence Consultants have in-depth knowledge of vessel margins management, including management of data associated with design change impacts and forward margins predictions based on proposed fleet implementation schedules. This includes the upkeep of margins management models as well as the ability to model and assess the cumulative impact of proposed changes in terms of space, weight, weight/buoyancy balance (submarines), stability, electrical power, thermal loads and the corresponding impact on cooling systems.
