NAVAL FUEL INSTALLATION ROYAL NEW ZEALAND NAVAL BASE

DEVONPORT, AUCKLAND

The Opportunity Fitzroy Engineering Group were awarded the Engineering,

Procurement, Construction, Project Management,

Commissioning and Training contract for these two concurrent

Naval upgrade projects – the Navy Fuel Installation Project (NFI)

and the Waste Treatment Plant Project for Oily Bilge Water

(OBW).

The Project The NFI Project required the storage of 2.2 million litres of

NATO Marine fuel and 750,000 litres of NATO Aviation fuel,

unloading and loading capabilities between wharf fuel

bunkering stations and storage facilities via under-wharf, under-

ground and above ground pipes, unloading and loading

capabilities between road tankers and storage facilities,

treatment of fuel using filtration and separation filters.

The OBW project required the storage of 150,000L of Oily Bilge

Water at a plant located near the fuel facility, unloading and

loading capabilities between wharf OBW bunkering stations and

storage facilities via under-wharf, under-ground and above

ground pipes, automatic skimming of oil layers in tanks,

dissolved air floatation treatment of the dirty aqueous bilge

water, recovery of waste oil for sale, discharge of treated

effluent to local sewer system.

The fuel storage system is located inside underground bunkers,

typically 8 m diameter and varying lengths from 45m to 60m. All

the fuel tanks are located inside these bunkers and access to

them via connecting tunnels of 3m diameter.

These fuel storage tanks of cylindrical horizontal configuration

with dimensions of 2.4 m ID x 12m long, 2.4m ID x 24 m long,

2.4m ID x 60 m long, 5.5 m ID x 65 m long and 5.5m x 45 m long

were constructed in place inside the bunkers. The fuel

treatment and pumping facilities are located outside the

bunkers in the main access tunnel. The control room is also

located in the same access tunnel.

Scope • Process design and development & HAZOP of P&IDs for both

projects

• Development of all process functional descriptions and

ladder logics for software programming, development of all

PLC screen displays

• Supervision of software programming, dry-run, simulation

and factory acceptance test

• Development and design of all process control systems

• Selection, specification, procurement of all plant

• Development of all plant, above round/underground/under-

wharf pipework layouts and production of detailed

construction drawings including pipe stress analysis

• Design and Calculation of all storage tanks to PD 5500, API

650, NZ Seismic Codes and application of Finite Element

Analysis
