What do SOLAS chapters XI-1 and XI-2 contain?
Short answer
| XI-1 safety | XI-2 security | |
|---|---|---|
| Regulations 1 to 4 | RO Code; enhanced surveys; IMO number; PSC on operational requirements | definitions; application; security levels; ISPS Part A and the ISSC |
| Regulations 5 to 7 | Continuous Synopsis Record; casualty investigation; atmosphere-testing instruments | the company’s duty to the master; ship security alert system; threats in the territorial sea |
| Regulations 8 to 13 | — | master’s discretion; control and compliance; port facilities; alternative and equivalent arrangements; information to IMO |
- XI-1, safety: 1 recognized organizations under the RO Code; 2 enhanced surveys of bulk carriers and tankers (ESP Code); 3 the IMO number marked permanently; 4 port State control on operational requirements.
- XI-1 continued: 5 the Continuous Synopsis Record; 6 casualty investigation under the Casualty Investigation Code; 7 portable atmosphere-testing instruments for enclosed spaces.
- XI-2, security (the ISPS chapter): 3 security levels set by Governments; 4 companies and ships comply with ISPS Part A (assessment, plan, CSO and SSO, ISSC); 5 the master’s information; 6 the ship security alert system.
- XI-2 continued: 7 threats in the territorial sea; 8 the master’s discretion; 9 control and compliance (inspection, delay, detention, expulsion); 10 port facilities; 11 and 12 alternative arrangements; 13 information to IMO.
- One line: XI-1 is safety, XI-2 is security; both apply to Indian ships through MS Act 2025 s.147.
- As Chief Engineer: the enclosed-space instruments (XI-1/7), the enhanced-survey structure (XI-1/2) and the IMO number in the engine room (XI-1/3) are mine; I support SSAS power and access control.
