Each topic below brings together, in a single place: an operational explanation, the regulatory reference, scope of application, procedure, practical example, what typically goes wrong, common mistakes, what the Port State Control Officer (PSCO) checks, operational tips, a checklist and FAQ — with the regulatory reference verified against the primary source.
EEXI and Engine Power Limitation (EPL)
How to verify EEXI and manage EPL/ShaPoLi: calculation, technical file, power reserve and manoeuvring documents, keeping technical efficiency separate from annual CII.
CII (Carbon Intensity Indicator)
How to read annual CII and the A–E rating, establish applicability and respond to three consecutive D ratings or one E with a corrective-action plan in SEEMP.
SEEMP Part II and Part III
SEEMP connects energy management, DCS data collection and CII planning through three parts with distinct scopes, verification and update requirements.
IMO Net-Zero Framework
The IMO Net-Zero Framework remains an unadopted draft: MEPC 84 arranged further work toward MEPC 85 and possible resumption on 4 December 2026, not finalized detailed guidelines.
Environmental Vetting and GHG Rating
RightShip GHG Rating A–E is distinct from Safety Score, inspection age trigger and charterer policies; nomination consequences require a current attributable policy.
Alternative Fuels and Operational Readiness
Readiness starts from the actual fuel approval route: mandatory IGF provisions for natural gas; for other fuels SOLAS II-1/55, applicable interim guidance and flag/RO requirements.
EU ETS and FuelEU Maritime
EU ETS, MRV and FuelEU have distinct scopes: in 2027 ETS adds offshore ships ≥5,000 GT; 400–4,999 remains proposal/review, while FuelEU concerns ships above 5,000 GT.
Ballast Water Management Convention In Depth
From the BWM plan to discharge: system operation, commissioning, records and exemptions, distinguishing applicable obligations from changes still under development.
Biofouling Management
The Biofouling Guidelines are voluntary and create no IMO-certified provider: before in-water cleaning, check port/coastal-State rules and assess the service technically.
Underwater Radiated Noise (URN)
MEPC 84 agreed in principle to extend the URN experience-building phase to end-2028; the Revised Guidelines remain voluntary.
Onboard Carbon Capture and Storage (OCCS)
OCCS is an emissions-abatement technology, not a fuel or energy source; CII/EEXI/NZF accounting, testing, survey and certification remain to be established by applicable instruments.
Shore Power and Cold Ironing (Onshore Power Supply)
Preparing a shore-power port call: AFIR and FuelEU duties, timelines, ship–shore compatibility and the evidence to retain.
Wind-Assisted Propulsion Systems (WAPS)
WAPS can reduce propulsion power and fuel use in favourable conditions, but benefit depends on the ship, route, wind, arrangement and auxiliary loads and must be verified against a comparable baseline.
Methanol and Ammonia Bunkering: Infrastructure and Real Cases
Methanol/ammonia bunkering availability is route- and port-specific: verify supplier, transfer mode, approval, technical standard and emergency arrangement directly.
Just Transition and the Social Impact of Decarbonization
The transition requires competence tied to the actual fuel, technology, role and arrangement: STCW.7/Circ.25, .26 and .27 provide interim guidance, while MJTTF frameworks remain non-mandatory resources.
Review of the EU MRV Framework in Light of the EU ETS
The 2026 EU review produced COM(2026) 620 final: it is a legislative proposal, while current MRV scope remains governed by consolidated Regulation (EU) 2015/757 until a final act is adopted.
CII: 2027-2030 Reduction Factors and New SEEMP Granularity
CII factors for 2027–2030, the enhanced DCS data timetable and SEEMP updates: connected topics with distinct rules and dates.
