Jet Fuel Tank Conversion

Channel Infrastructure New Zealand is undertaking the repurposing of Tank T06 to serve as a finished jet fuel storage facility for a private customer.

DFL is responsible for the complete delivery of the repurposed jet fuel storage facilities, encompassing front end engineering design (FEED), procurement, construction, pre-commissioning, and handover. Key execution objectives include:

Robust Project Management Apply sound project management practices across all project phases to ensure alignment, efficiency, and delivery.
Health, Safety, and Environmental ExcellenceMaintain exemplary performance in HSE, adhering to CINZ’s standards and best practices.
Schedule Adherence Complete all activities within the agreed timeline.
Performance Monitoring Implement and track project KPIs to ensure progress and identify improvement opportunities.
Stakeholder Engagement Manage interfaces with stakeholders and adjacent works to minimize disruptions and enhance collaboration.
Engineering Compliance Meet all engineering standards and performance requirements as outlined in the design documentation.
Construction Quality Deliver facilities to the specified quality standards and workmanship expectations.
Statutory Approvals Secure all regulatory and statutory approvals relevant to the scope of work.
Commissioning Support Conduct pre-commissioning and assist the operations team during final commissioning, if required.
Completion Criteria Full completion is achieved when DFL has delivered all aspects of work in accordance with this scope.

Execution Strategy

DEFINE (front-end engineering development)

A truncated DEFINE phase was undertaken (June 2024 - August 2024) to undertake front-end engineering to:

define the execution scope,
investigate and select options,
mature the underlying technical basis, and
establish the total-installed costs, execution schedule and methodology.

The FEED duration was reduced from 13 weeks to around 9 weeks at CINZ’s request to enable a sanction package to be delivered in advance of public announcements and FID slated at the end of August 2024. This reduced timeframe meant some activities originally planned during FEED were not completed and instead rolled over into detailed design post-FID.

EXECUTE (Procurement and Construction)

Due to the brownfield nature of the project, the project requires considerable planning around how the final hook up to the existing piping systems is to be carried out, as well as integrating the required electrical and instrumentation modifications.

The EXECUTE phase is currently on-going and has a high degree of overlap between the following scope groups:

Detail design – finalising all technical documentation and drawings to AFC.
Procurement – the project timeline dictates early procurement of long-lead items is required for the tank roof, motor-operated valves and steel plate for the new tank floor. For these items, orders are required to be placed early in the EXECUTE phase.
Demolition works – the tank IFR needs to be demolished before any construction work on T06 can proceed.
Construction – a core site construction requirement is that DFL shall advise operations well in advance of what machines are entering the T06 construction zone. This is required as T04 is in active jet storage service and is adjacent T06 to. As T04 and T06 share the same compound, the compound is not considered greenfield as it was for the T04 conversion.

Key Objectives

Maintaining excellence in health, safety and environment performance – no harm to people, assets or the environment.

Quality – all appropriate regulatory and legislative requirements will be met, with all works being completed in accordance with DFL’s ISO9001 accredited quality management systems.
Completing the project within the agreed project schedule. The schedule target for successful handover to CINZ operations team is 2 September 2026.
Effectively manage all stakeholder interfaces that impacts on other work.
Meeting all engineering standards and performance requirements.
Pre-commissioning, handing over of the facilities and subsequently provide commissioning support and assistance to the operation team.
Cost – deliver the project within the agreed budget; and
Production – minimal impact on existing production availability during project execution
