Statutory Documents - MCA Publications - PYC - A Code of Practice for Yachts Carrying 13 to 36 Passengers (The Passenger Yacht Code) - Chapter 7 - Life-Saving Appliances and Arrangements - 7.26 Alternative Design and Arrangements:
7.26 Alternative Design and Arrangements:
Purpose
(1) The purpose of this section is to provide a methodology for the assessment and acceptance of alternative design and arrangements for life saving appliances.
General
(2) Life-saving appliances and arrangements may deviate from the requirements set out in this Chapter, provided that the alternative design and arrangements meet the intent of the requirements concerned and provide an equivalent level of safety to Chapter III of SOLAS.
(3) When alternative design or arrangements deviate from the prescriptive requirements of this Chapter, an engineering analysis, evaluation and approval of the design and arrangements shall be carried out.
Engineering Analysis
(4) The engineering analysis shall be prepared and submitted to the Administration, based on the guidelines developed by the IMOfootnote and shall include, as a minimum, the following elements-
-
(a) determination of the ship type and the life-saving appliance and arrangements concerned;
-
(b) identification of the prescriptive requirement(s) with which the life-saving appliance and arrangements will not comply;
-
(c) identification of the reason the proposed design will not meet the prescriptive requirements supported by compliance with other recognised engineering or industry standards;
-
(d) determination of the performance criteria for the ship and the life-saving appliance and arrangements concerned addressed by the relevant prescriptive requirement(s)-
-
(i) performance criteria shall provide a level of safety not inferior to the relevant prescriptive requirements contained in this Chapter; and
-
(ii) performance criteria shall be quantifiable and measurable;
-
-
(e) detailed description of the alternative design and arrangements, including a list of the assumptions used in the design and any proposed operational restrictions or conditions;
-
(f) technical justification demonstrating that the alternative design and arrangements meet the safety performance criteria; and
-
(g) risk assessment based on identification of the potential faults and hazards associated with the proposal.
Evaluation of the Alternative Design and Arrangements
(5) The engineering analysis required by subsection (4) shall be evaluated and approved by the Administration, taking into account the guidelines developed by the IMOfootnote.
(6) A copy of the documentation, as approved by the Administration, indicating that the alternative design and arrangements comply with this paragraph, shall be carried on board the ship.
Exchange of Information
(7) The Administration shall communicate to the IMO pertinent information concerning alternative design and arrangements approved by them for circulation to all Contracting Governments.
Re-evaluation due to Change of Conditions
(8) If the assumptions and operational restrictions that were stipulated in the alternative design and arrangements are changed, the engineering analysis shall be carried out under the changed condition and shall be approved by the Administration.
