Question:
All vessels have noted "Vessel must be constructed under comprehensive stability assessment.". Please provide clarification of the intent and extent of this requirement. Comprehensive stability criteria for offshore vessels is based on stability area under a curve and is usually not achievable for small vessels with limited underdeck buoyancy. That is why NSCV has criteria specifically for smaller vessels.

If an inclining experiment is completed and a computer analysis utilised, as would be expected for larger vessels assessing against comprehensive criteria, can the small vessel criteria contained within sections 7A, 7B or 7C be applied as appropriate in accordance with NSCV? Ultimately, is it the process of a practical stability proof test that QPS wants to avoid, or is it mandating the use of NSCV 5A/5B criteria?

Question:
Confirming post the industry brief this morning that category C vessels have a weight limit of 3.5t on the trailer ready to be deployed (i.e. full of fuel and with safety gear, etc)? I cannot source that requirement written anywhere in the supplied tender documentation.

Do any of the other category vessels have a trailer able weight limit?

Please refer to Addendum 4.

Question:
1. Please confirm if foam-collared vessels are acceptable to satisfy the “soft collar” specification for category C vessels.

2. Under the respective ‘regulatory compliance’ sections of Part B, attachment 1, all vessels are required to have LEVEL flotation. Please confirm if this is required, or if the vessels may satisfy the requirements of NSCV C6B by other allowable means such as suitable spacing and number of watertight bulkheads. This question is particularly relevant for category C and D vessels.

3. NSCV C1 section 4.20 requires class 2 vessels to have a toilet and washbasin for voyages over 2 hours with passengers, and 4 hours with crew only. Table 12 note A in this section of the NSCV defines length of voyage to be time without access to shore-based toilet facilities. Category B and C vessels are specified to be deployed for “Patrols or Rescue lasting 8 hours” in their respective sections of Part B, attachment 1. Please clarify if toilet and washbasins are to be fitted to these vessels.

4. Under the respective ‘miscellaneous’ sections of Part B, attachment 1, category C and D vessels are required to have a “fire/water pump with hose D coupling”. This appears to be a QPS specification in excess of NSCV requirements, and so there is no guidance on sizing from AMSA. Please specify intended use, size/output requirements and hose requirements.

Question:
Query on Inflatable vs foam collars.

Category A specifically mentions inflatable collar

Category B mentions 'soft collar'

Category C mentions 'soft collar'

Category D1 specifically mentions foam collar

Category D2 mentions 'soft collar'

Does this mean that Category B, C & D2 could be either air or foam filled soft collars?

Question:
Clarifying discrepancy with regards to D2 specification in Part B contract details - Attachment 1 & Part C response schedule - Schedule 3 technical solution.

The layout described in Part B for Category D2 state "Internal seating for minimum (6) via shock mitigating seats or seat bases. Additional seating per survey requirement for total 12 pax."

Whereas the layout described in Part C for category D2 states "Seating for (2) crew (minimum) via shock mitigating seats or seat bases"



Assume Part B is the correct layout description?

With regards to QPS29294 for the “Provision of QPS vessels 2026/27”, due to competing work obligations and also the ability to source suppliers costings for all categories, we are struggling to meet the current deadline and we would like to request an extension of the closing date to Wednesday 22 July 2026 at 2.00pm AEST.

Could you please advise if this request is possible?
