Change Impact Analysis
CBOM Change Event — 14 April 2025 · Detected by Agent · Awaiting review
⚠ CRITICAL IMPACT DETECTED
XBOM-PROP-001 (Main Engine) specification updated to Rev 3. NOx compliance standard modified. 1 active supplier has submitted TNC responses against Rev 2 specification. Those responses are now potentially invalid.
Change Event Details
Agent assessment · Confidence 94% · Materiality CRITICAL
This is a mandatory regulatory change. It cannot be deferred to the next ship. All active procurement against this specification requires immediate review.
Impact Cascade — All Affected Procurement Records
3 active procurements affected across 1 ship
NVL-OPV-11 · TNC Active (Day 23 of 40)
SecureForce Marine has submitted TNC responses for 38 of 47 requirements against Rev 2 specification. Requirement 12 (NOx compliance — affected by this change) has been marked COMPLIANT by the supplier against the OLD standard. This compliance position is now invalid.
NVL-OPV-11 · Technical Document Submission (Day 6 of 15)
Supplier technical submissions may reference NOx compliance as a linked system requirement. Submissions received from 2 of 4 suppliers. Issue clarification notice before remaining 2 submit.
NVL-OPV-11 · SOTR Raised (Day 2 of 3)
SOTR draft references NOx compliance requirement in Section 3. No supplier activity yet. Update SOTR before RFQ issue.
NVL-OPV-11 · PO Generated — Complete
Procurement complete. Change noted for records only.

XBOM to PBOM Translation Intelligence
NVL-OPV-12 · 23 items awaiting classification · AI proposals ready
ECDIS Navigation System — Integrated Bridge
XBOM spec excerpt: “ECDIS compliant to IEC 62288, IMO Res. MSC.302(87), 24" display minimum, S-57/S-63 chart support, ARPA integration”
⚡ Classification: SOTR Equipment
Basis: Matched to NVL-OPV-11 XBOM-NAV-001 (87% specification similarity). Complex technical compliance requirements mandate competitive SOTR process.
Accepting will create PBOM record and trigger SOTR generation
VHF/DSC Radio Installation
Bridge Monitoring and Alert Management System (BNWAS)
Confidence MEDIUM — BNWAS specification includes software integration requirements with existing bridge systems. Unclear whether standalone procurement or integrated with ECDIS package.
⚠ Recommend D&E clarification before proceeding: confirm whether BNWAS is procured as standalone or as part of ECDIS integrated package.
Custom Hull Frame Bracket — Midship Section Variant
Classification: Insufficient confidence to propose automatically
This item has no strong historical match. The “variant” designation suggests a modified design not previously procured. Recommend: senior procurement officer review + market sounding before classification decision.
Basis for LOW confidence: closest match NVL-OPV-09 structural bracket (42%). Specification differs in material grade, bracket geometry, and weld specification.

NVL-OPV-12 | SOTR | Navigation and Bridge
STATEMENT OF TECHNICAL REQUIREMENTS
The ECDIS shall be compliant with IEC 62288 (2014) — Presentation of navigation-related information.
The ECDIS shall display official ENC charts in S-57 format and shall support S-63 data protection standard.
The equipment shall comply with IMO Resolution MSC.232(82) performance standards for ECDIS.
⚠ IMO MSC.232(82) is in effect but MSC.327(89) (2016) added amendments. Verify whether both resolutions should be cited or MSC.327(89) alone is current.
Display screen size: minimum 24 inches diagonal. Viewable in all ambient light conditions. Anti-glare coating mandatory.
The ECDIS shall have integrated ARPA (Automatic Radar Plotting Aid) capability compliant with IEC 62388.
The supplier shall provide type approval certificate from a recognised classification society listed in the DNV approved product register.
⚠ OPV-11 accepted GL approval. DNV rules for this ship class require DNV or BV type approval specifically. Confirm accepted classification society list.
