State of the Wreck Presentation – Dive Trail Videos

This interactive dive trail map provides hyperlinks to view footage of ten dive trails covering the main areas of the wreck site. The videos were shot in June and July of this year (2015).

To view each video, please click on the blue rectangle containing the number of the dive trail you want to watch. A number of these videos are being shown to submitters ahead of the hearing, as part of an update on the current state of the wreck.

Supplementary Section 87F Report

The Bay of Plenty Regional Council’s recently filed supplementary s87f report provides some important further context to the application, including a summary of submissions, identification of the relevant statutory provisions and further narrows the issues relevant ahead of the hearing. A copy of the report can be read by clicking here.

BOPRC Rena Dive Report

The Bay of Plenty Regional Council’s Recreational Dive Safety Expert Report and Summary Video has just been released, please click here to read the report.

The report was prepared by Jeroen Jongejans of Dive Tutukaka, who has run dive operations for nearly thirty years and been instrumental in supporting World Heritage Status for the Poor Knights and an advocate for Marine Reserves and National Parks around New Zealand

The following video below captures only short segments of the footage captured, by David Abbott.

* The site visit was undertaken prior to Tropical Cyclone Pam and a second dive survey will be undertaken in due course.

ADUS Survey

Following Cyclone Pam another multibeam survey was carried out by ADUS DeepOcean surveyors between the 18th and 23rd of March, which, as illustrated below confirms further deterioration of the wreck.

The blue outline shows the stern structure in 2012, the red outline in March 2014 and the grey outline in March 2015. This sequence of movements demonstrates how the aft section, as previously forecast by naval architects appointed by the insurers, is expected to continue to deteriorate and move into deeper water over time as a result of natural forces.

The ADUS survey also identified some movement of the bow pieces, which divers have since inspected and identified debris previously trapped that is now being recovered.

Oil Recovery Update

Before Cyclone Pam, Resolve Salvage & Fire conducted multiple deep penetration dives into the wreckage at depths between 35 and 48 metres, and successfully recovered 992 litres of oil trapped within and near the substantially degraded engine room.

This operation was in response to intermittent oil sheens being observed on the surface during debris clearance operations. The divers were first tasked with locating the source of the sheens and then with recovering the pockets of oil that could safely be recovered. These efforts have further reduced the minor oil quantities remaining within the structure.

Farewell Resolve Salvage & Fire – Welcome New Zealand Diving & Salvage

Following completion of the susbtantial work planned to be performed by Resolve Salvage & Fire, recovery work now continues with a New Zealand operator, Wellington-based New Zealand Diving & Salvage (NZDS), which will focus on further reducing remaining debris.

NZDS are currently scaling up their team of divers and have made significant progress, recovering over 43.3 tonnes of debris to date.

Their scope of work over the coming months will be to continue removing any remaining diver entanglements and recovering inorganic materials and aluminium ingots to a depth of 30m. Videos shot by NZDS divers of the areas they will be working in can be viewed by going to page 4 of the following report, please click here.

Should any further oil sheens occur NZDS would also be resourced to undertake further investigations, and if safe, to remove the oil at its source.

NZDS will also continue to remove any identified deposits of copper where recoverable using specialist underwater suction equipment procured by the owner and insurer. For more information about the copper and its recovery, please read the TMC Copper Recovery Report.

The NZDS team includes divers with substantial experience working on the Rena in previous contract roles.

The Rena owner and insurer would like to recognise and thank the Resolve Salvage & Fire team for its efforts since August 2012 in performing many complicated and difficult assignments, while maintaining an exemplary health and safety record.
