PSG (formerly PSG Marine and Logistics) provides port agency services for vessel operators, owners and charterers working across Scottish ports.
The service supports the practical coordination needed before arrival, during the port call and before departure.
This can include pre-arrival notifications, berth scheduling, authority coordination, customs support, crew changes, ship supplies, waste handling, technical support and reporting.
PSG helps vessel operators, owners and charterers coordinate the key stages of a port call, from arrival planning through to departure.

PSG can support pre-arrival notifications, berth scheduling and coordination with the relevant port contacts. This helps reduce uncertainty before the vessel enters port.
The team can assist with customs support, crew changes, ship supplies, waste handling and urgent in-port requirements. This keeps vessel support organised while the vessel is alongside.
PSG can support departure coordination, reporting and final communication with the vessel team. The aim is to keep the port call clear, controlled and aligned with the vessel schedule.

Vessel Calls With Wider Port Requirements
A call may involve cargo readiness, quayside access, lifting activity, storage or onward transport.
In these cases, PSG can connect the agency work with wider port operations.
This helps vessel operators keep the port call aligned with practical site requirements. It also gives project teams a clearer route when the vessel call forms part of a larger marine or logistics scope.

Maritime logistics is the management of vessel operations and marine transportation to support offshore projects. Think of it as a coordinated system that moves people, equipment, and supplies across water efficiently and safely. At PSG, we handle everything from vessel operations to crew transfers, ensuring your marine operations run smoothly.
Marine logistics is essential because it keeps offshore operations running efficiently. Without it, offshore energy projects, marine construction, and renewable energy installations wouldn't be possible. It ensures your equipment arrives on time, your crews are safely transported, and your operations maintain continuous support. This seamless coordination reduces costs and minimizes project delays.
