Rulings

Rulings allow petroleum operators to continue with activities that existed before the EEZ Act came into force.

You can see the rulings requested by these petroleum operators below.

BW Offshore Plus

BW Offshore (BWO) is an international company that owns the FPSO (floating production storage and offtake facility) Umuroa. The FPSO has been operating in the Tui Field within PMP 38158, approximately 50 kilometres off the coast of Taranaki. BWO wishes to disconnect the FPSO Umuroa from the oil wells operated by Tamarind Taranaki Ltd (in receivership) and remove it from the Tui Field.

In order to do so, BWO have lodged two ruling requests with the EPA:

  1. for the temporary placement of the mooring lines and anchors until BWO can retrieve them before February 2021, and
  2. for disconnection and placement on the seabed of the subsea equipment

Both rulings are required before BWO can fully disconnect and sail the FPSO Umuroa away.

Ruling 2 request (EEZ500029)

On 23 April 2020, we did not provide the parts of the second ruling (Ruling 2, EEZ500029) to BW Offshore to disconnect the offshore installation the FPSO Umuroa from the subsea equipment (SSE) and placement of it on the seabed. The uncertainty in the effects on the environment and existing interests of the proposed activities prevented us from being assured they would be minor or less than minor. We provided part of Ruling 2, EEZ500029 for the use of Remotely Operated Vehicles.

In effect, BWO are not authorised to undertake the other disconnection activities (including activities authorised under its initial ruling) unless the disconnection of the subsea equipment is lawfully authorised.
