• EEMUA 159 fitness for purpose assessments
• Tank decommissioning
• Tank designs to EN14015
• Tank construction works

The project covered tank inspection, tank assessment, asset demolition, tank design, contractor selection and appointment, new tank build and site supervision. Trident was involved through the project life cycle from inception to handover.

Project : HVO Product Conversion

Sector : Fuel Distribution Terminal

Site : Aberdeen,Scotland

Scope: Trident Engineering was commissioned to manage the full project lifecycle—from initial design to handover—for the introduction of HVO (Hydrotreated Vegetable Oil) import and export operations at the facility. This included the integration of new equipment and the adaptation of existing storage.

Key aspects of the project included:

• Repurposing a 3.33-million-litre storage tank, previously used for a different product, for HVO storage. The tank underwent thorough cleaning, inspection, and repair before being utilised.
• Importing HVO into the tank from the quayside using a combination of new and existing pipework.
• Installation of new pipework to facilitate a bunkering operation for marine services and support a gantry operation utilising an existing loading arm to fill road tankers.
• Installation of two new 55kW pump sets on existing bases for bunkering and gantry operations. The pumps were precision laser-aligned and vibration-checked before being put into service.
• Upgrading existing soft-start units and starters in the switchroom to comply with current regulations, while retaining the majority of the existing cabling for cost-effectiveness. Additional signal cabling was installed to connect the switchroom PLCs with the new equipment.
• Enhancing quayside lighting for improved visibility during bunkering and general maintenance, based on a comprehensive lighting survey and design.
