Reporting Matter ANM 15

Offshore Man-Made Structure

Aims of Reporting Matter

Short overview about the international development of OREI in connection with AtoN matters

Derivation of main tasks from the questionare sended by the memberstates, f.e.

- Marking (AIS, RACON, Lights, Numbering)

- Distance to shipping routes and TSS

- Other questions

Other experiances with special tasks in connection with:

- Marking of OREI in general,

- Marking of Windfarms

- Other methods to improove the safety of ships traffic

Considerations and investigations concerning AtoN in connection with OREI.

How to get Informations

2009 from:

UK, Netherlands, France, Korea, Portugal, Germany

2010 from:

UK, Latvia, Norway, France, Germany, Sweden

In 2008 the former Recs. O-114, O-116. O-117 and O-131were unified to the Rec. O-139.

This Rec. contains different Marking Systems: Offshore Structures in General, marking of Aquaculture

Farms, marking of OWF, marking of Wave and Tidal Energy Devices

All responses will be collected and are ready for use in the working groups as required.

The informations by the memberstates of

the questionare are a part to observe the

development of OREI and identify

questions that raising in connection with

the equippment with AtoNs and the safety

of navigation

Questionare

Member State/ Organisation

Kind of OREI Aprox. Number

Single/ area Distance to shore

Distance to TSS/ Routes

Kind of AtoN Specification of vis. aids

Example Offshore-Windfarms,Tidal Current devices,Wave Energy devices

5 operational OWF, 5 under construction, 14 in planning.1 tidal deviceWave energie being tested

Operational OWF 25 to 30 turbines. Future OWF 25 to 250 turb.Tidal dev.stands allone.

OWF 4 to 5 miles of the shore, other within 12 miles.Tidal 1 mile.Wave testing 12 miles.

Aproved area for OWF:5 nm to next TSS,Tidal: 23 nm to shipping route.

OWF: Fixed AtoN, AIS, Fog horn etc.Tidal: Floating AtoN, partly fitted with AIS,sonar transponder.All area covered by VTS

Floating aids and lights in the structure in acc. with IALA guidelines and COLREGPartly additional lights for inner turbines in OWF

Questionare to get some ideas what‘s going on!

All responses where collected and are ready for use in the working groups as

needed..

Raising Questions for Markig of OWF

The b.m. bullet points are derivated from the memberstate reports 2009 and 2010 and reflects the discussions

with stakeholders and marine experts. The sequence means no ranking.

Requirement of fog signals,

Use of AIS,

Horizontal angel of lights,

Lighting of inner structures,

Unified numerical marking of structures for search and rescue reasons,

Use of inverse illumination for short range marking,

Use of RACON,

Distance to TSS and ships routes,

Raven Kurtz23.09.2010 S11

Example: Distance to TSS

Memberstates Reports:

Netherlands different

Norway N.A.

Sweden 5

France 20 nm

Germany 2 nm

Latvia NIL

Portugal

UK N.A.

No international Rules.

Different view points for existing TSS and new TSS in conjunction with WOF.

Specific situation is importand (kind and number of traffic, risk of collision and

pollution)
