Are you an experienced marine professional ready to take on a key role in a live harbour environment? Do you enjoy balancing operational delivery, safety, and stakeholder management? Do you want to be part of the team working on a nationally significant infrastructure project? We’re looking for a Deputy Harbour Master to join NASH Maritime, supporting Harbour Authority operations for the Sizewell C project, based at our client’s office in Suffolk. This is a 12-month contract, with the possibility of further extension.
In this hands-on role, you’ll support the Harbour Master in managing day-to-day marine activity, helping ensure safe, compliant and efficient operations across a busy and evolving construction environment. You’ll work closely with contractors, regulators and project teams, acting as a key point of coordination and decision-making on navigation safety.
Alongside operational delivery, you’ll play an important role in maintaining an effective marine safety management system compliant with the Ports & Marine Facilities Safety Code (PMSC), supporting risk management, and ensuring activities align with statutory requirements and best practice.

- Marine operational experience preferably at Assistant Harbour Master or equivalent level
- Demonstrable track record of managing navigation safety in harbour or port environments
- Knowledge and understanding of the Ports & Marine Facilities Safety Code (PMSC)
- A developed understanding of relevant occupational health, marine safety and environment obligations and systems
