Friday 1 March 2013

From Monday 4 March the marine farms operated by Tasman Bay Ring Road Farming Ltd and Golden Bay Ring Road Farming Ltd will be continuing expansion work in both Tasman and Golden Bays.

This work is likely to take approximately eight weeks. There will be increased workboat and diving activities during this period.

Please read the full notice and the advice below.

Navigation Safety Warning

Further to local Navigation Safety Warning TDC2013/02, Tasman Bay Ring Road Farming Ltd (TBRRFL) have advised Tasman District Council that they have completed anchor installations for stage 2 of their permanent mussel farming development in AMA3B, pursuant to Coastal Permit RM050101V1, and over the upcoming month will be setting up farming lines. For further details, refer to TDC2013/02.

  1. Golden Bay Ring Road Farming Ltd (GBRRFL) have advised Tasman District Council that they intend to proceed to stage 2 of their permanent mussel farming development in AMA2 (northwest of Tarakohe Harbour), pursuant to Coastal Permit RM070990V1.
  2. This is an expansion of their two existing full-density farm sites. Stage 2 is 2/3rds density occupation of the entire consented area, forming a rectangle bounded at the seaward edge by the existing North cardinal and East Cardinal marks.
  3. TBRRFL intend to begin placing anchors from Monday 4 March 2013, and follow with installation of backbones and growing lines. There are currently approximately 120 lines in place as stage 1. Approximately 158 new lines will be installed as stage 2. Backbone lines will be bundled in groups of 2 or 3 lines once anchored at one end, prior to connection to their second anchor. These bundles may present a hazard particularly to keeled vessels.
  4. Aids to Navigation: The East Cardinal mark will be moved to 40°46.03’S; 172°52.88’E. The three existing special marks between the North Cardinal mark and the East Cardinal will be relocated. No additional special marks will be installed.
  5. This work is likely to take approximately eight weeks. There will be increased workboat and diving activities during this period.
  6. The seasonal mussel and scallop spat catching sites nearby will not be affected. Normal operations continue in these sub-zones.

Advice

Until changes to marine farming boundaries are formally notified by Land Information NZ via Notices to Mariners, users of these areas are advised to make interim temporary navigation chart corrections as appropriate.

Vessel operators are advised to avoid unnecessary navigation within the areas bounded by cardinal marks at AMA2 - Puramakau (Golden Bay) and AMA3 - Te Kumara (Tasman Bay), especially during times of darkness or poor visibility.

Users of high-speed and small craft are cautioned against navigating at speed within the areas being developed. In particular, the speed limit of 5 knots within 200m of any structure, any vessel showing the dive flag (Code flag A) and 50m of any other vessel should be strictly observed.
