Safety at Sea

Safety at Sea

Safety at Sea Ltd brings together specialists in seakeeping, manoeuvring, stability, hydrodynamics, fire protection, evacuation as well as safety engineering and risk analysis. The company’s scientific approach used for solving practical problems allows us to provide customers with cost effective solutions that fulfil their highest expectations.

Serving clients across the marine and offshore industries we undertake a variety of work; from feasibility and concept design to risk assessment of marine operations. We work for designers, builders as well as owners/operators in advisory, supporting or project leading roles.

  • Ship stability
  • Design support (naval architecture and engineering analysis)
  • Safety engineering and risk assessment
  • Safety studies
  • Software

Safety at Sea also provides independent, high-quality technical advice to customers involved in disputes and/or litigation involving rule compliance, ship collisions, grounding, fire and structural failures.

Safety at Sea has also advised on and carried out studies for clients in various aspects of port design and operations. This activity has previously been delivered independently and in close cooperation with external experts. The combined capabilities of our mariners and naval architects can be tailored to cover most aspects of port design and operations.
