1 INTRODUCTION

The purpose of this report is to assess the feasibility of the proposed Old Salt Perth Entertainment Barge installation and operations.

This report reviews regulatory requirements and assesses the mooring loads and mooring options available. This report does not assess the requirements of any support vessel/s. This report is confined to the marine aspects of the barge only and does not comment on the business or catering side of the operation.

This report assumes that the barge will be built overseas to classification society rules and will be delivered in survey.

2 SUMMARY

2.1 Survey

Three possible survey methods have been considered; classification society survey, local AMSA survey and foreign flag survey. Given that it is likely that the barge will be built and delivered in classification society survey, it is recommended that the vessel remain in survey with class as an Australian DCV. The advantages are that the vessel will not be limited in length and it is likely that it will be easier to extend the dry docking to every 5 years.

2.2 Barge

Reference B1 illustrates a suitable hull for the vessel Entertainment Barge. A more detailed vessel arrangement will need to be produced when the project progresses to the detailed design phase.

2.3 Manning

Preliminary discussions with the local survey authority indicate the minimum manning requirement is one MED2. It is recommended that the manning of the barge be revisited based on consideration of the vessel’s Safety Management System (SMS) and in consultation with DOTWA and AMSA.

2.4 Mooring

Several mooring methods have been considered for the Entertainment Barge. The most efficient and low impact mooring arrangement appears to be a four point mooring utilising SHHP anchors. Appendix B illustrates an example of preliminary design that would suit the Entertainment Barge.

3 REGULATORY FRAME WORK

At the time of writing this report, the author understands that the intention is for the vessel to be built and delivered in ABS classification society survey.

Under the National Law, even though the barge will be permanently moored, it is defined as a vessel and is, therefore, subject to survey requirements. Three possible paths to survey have been identified to date;

1. Classification society: Keep the barge in ABS/class survey and register it as a DCV,

2. Local AMSA survey: Transfer the vessel from class survey to local AMSA DCV survey governed by the NSAMS,

3. Foreign flagged vessel: Transfer the registration to a flag state, i.e. Cook Islands, comply with their survey requirements and operate under the Navigation Act as a foreign vessel.

3.1 Classification society

There are some advantages with keeping the vessel in class. AMSA will accept any vessel as a registered DCV if it is in class with a recognised organisation, i.e. a classification society. As such, the vessel could be taken out of classification society survey at any point and it would be accepted by AMSA as a DCV.

The NSCV states “Vessels of 35 m or more in measured length shall be classed, i.e. designed, constructed and maintained in accordance with the rules of a recognised organisation.” Keeping the vessel in class would allow some flexibility in the vessel length. If the vessel were to be over 35 metres in length, it would need to remain in class survey.

It should be noted that whilst a vessel may be in survey with a classification society, for a vessel to operate as a DCV, the equipment, manning, lifesaving, fire safety and accommodation sections of the NSCV must be adhered to.

A classification society will allow underwater surveys in lieu of docking (UWILD) providing certain conditions are met. This would effectively mean that the vessel’s hull survey could be carried out in situ with the use of divers instead of having to dry dock the vessel. There are a number of conditions that must be met, but they are not expected to be too onerous on a vessel of this type.

3.2 Local AMSA survey

As the vessel will be in class survey when it arrives, it will be accepted into local AMSA survey as a DCV as a matter of course. However, the vessel would be limited to 35 meters. If the vessel were to be less than 35 metres, the applicable rule set would be the NSCV. It should be noted that the NSCV invokes class rules for construction at any rate.

If the vessel were to be taken out of class survey and put into local AMSA survey under NSAMS, there could potentially be some survey cost saving, however, preliminary investigations seem to indicate that this saving would not be that great.

A survey schedule under NSAMS would require the vessel to be dry docked at the third and fifth years of the five year cycle. It is likely that AMSA would grant an exemption for the year 3 dry docking if equivalence with the class requirements for UWILD could be demonstrated. However, it is likely it would be simpler to keep it in class.

3.3 Foreign flagged vessel

It is the author’s opinion, because the vessel will be permanently operating in Australian waters, path no. 3, foreign flagged vessel, is not a viable option as it is intended for vessels engaged in international voyages.

4 BARGE

Reference B1 has been put forward as a typical example of a standard barge commonly manufactured in Asia. This barge is adequate in size, subject to the above survey requirements, for the intended layout shown in reference B2 and C1. As the vessel is intended to be permanently moored, the hull shape is fit for purpose.

Whilst there needs to be some more work done on the arrangement to properly deal with machinery, deck fittings and fire and safety equipment, it is the author’s opinion that there is sufficient deck area and compartment space to comply with all expected regulatory and functional requirements.

A generic equipment list for a class 1E vessel (i.e. passenger vessel, smooth waters) is attached at Appendix A. Whilst this gives a good indication of the equipment likely to be required, a more specific equipment list would need to be agreed with the local authorities due to the vessel’s unique set of operation circumstances.

It is intended at this stage that the sewage treatment plant be installed below deck, see reference C2. To properly maintain this system, we would recommend that sufficient access be built in to the vessel for this purpose. That is, the bolted flush man holes typically provided with these barges would not be practical in this instance. A hinged watertight door with regulation coaming and a step type ladder would be ideal in this situation. However, a hinged hatch with coaming and a vertical ladder would suffice.

Our understanding is that any on board generator sets would be in a purpose built, appropriately fire protected space above deck for ease of maintenance.

The accommodation layout of the vessel is intended to meet NSCV Part C Section 1. This includes compliance with Chapter 4, 4.11.4 Access for persons with disabilities.

It is intended that the support vessel and the barge will be designed/ballasted to ensure that the loading and off-loading decks on both vessels are level with each other to ensure safe transfer of passengers and personnel via a suitable short gangway.

5 MANNING

The vessel meets the requirements of Reference D8 and as such is subject to the survey requirements that applied to the vessel on 30 June 2013. This essentially means that the minimum manning requirement can be determined by the DOTWA.

Preliminary discussions with DOTWA indicate that the minimum manning for this vessel would likely be one MED2, however, this would depend on the size and complexity of machinery and would need to be confirmed as more details come to hand. DOTWA also indicated that the permanently moored barge could essentially share a master with the continuously operating support vessel on the condition that there was a continuous method of communication between the two vessels and line of sight was established at all times. Again this would need to be confirmed when more details come to hand.

Note that the above is the “minimum” manning requirement and the vessel’s Safety Management System (SMS) would indicate a more appropriate level of manning.

6 MOORING

A number of mooring methods were considered for this vessel. Required mooring characteristics are as follows:

• Directional stability, i.e. not allow the vessel to rotate

• Be capable of holding the barge in all weather conditions, i.e. permanently moored

• Low environmental impact

The original preference was to use spuds to hold the vessel in place. Unfortunately, due to the vessel’s requirement to be permanently moored, it was deemed the mooring needed to be able to withstand winds in excess of 60 knots. Due to the large sail area of the vessel, the loads are quite large. The holding power of a spud in mud/silt is difficult to determine and not as effective as an anchor. It was felt that the spuds presented too great a risk of dragging. They also require machinery to lift and lower presenting other unwanted risks.

Permanently fixed piles are very effective with regard to directional stability and holding capacity, however, they are very difficult to remove. It was felt that they presented too much of an environmental impact.



Page 4

It was decided that a four point mooring utilising super high holding power (SHHP) anchors presented the best option. Appendix B shows a preliminary mooring design suitable for the vessel and its intended location. This mooring design is based on a 1/50 year storm. The high holding power of some anchors allows a relatively small footprint on the river bed compared to the use of clump weights. Relatively short lengths of chain are then attached to each corner of the vessel to prevent it from rotating. The chain catenary helps hold the vessel in situ which also prevents the chain from sweeping across the river bed as single point moorings can. The four point mooring is relatively easily installed and can be easily removed at a later date with little impact.
