In March, the International Maritime Organization
(“IMO”) announced the release of the Ship-Port Interface
Guide (the “Guide”)1 for the purpose of
reducing Greenhouse Gas Emissions (“GHG”).
The Guide was developed by the Global Industry Alliance2
to Support Low Carbon Shipping pursuant to the IMO-Norway
GreenVoyage2020 project, 3 the
Paris Agreement,4 and the United Nations 2030
Agenda for Sustainable Development.5 The Guide contains
practical steps to be implemented for the overarching purpose of
reducing GHG in the world shipping industry. A number of commercial
shipping interests, including the cruise industry, have
collectively endeavored to reduce GHG for the shipping industry. To
that end, the Global Industry Alliance considered that the average
lifetime of a commercial ship is approximately 25 years.
The practical solutions set forth in the Guide require smaller
capital investments and operational costs to implement the
protocols. Additionally, the steps established within the
Guide are easily established and conducted in shipping
operations. Finally the Measures contained
within the Guide are projected to sharply curtain GHG emissions
The Guide contains 8 Measures that are easily implemented. The
Measures are as follows:
- Measure 1: Facilitate Immobilization in
Ports. This Measure is designed to reduce vessel time in
ports. The Measure recommends that work and repairs to the main
engine proceed simultaneously with cargo loading and unloading
- Measure 2: Facilitate Hull and
Propeller Cleaning in Ports. Similar to Measure 1,
this protocol also recommends that hull and propeller cleaning
transpire at the same time as cargo loading and offloading.
Although many ports do not allow cleaning of a vessel hull in port
to prevent the transmission of invasive species, the Guide suggests
following the BIMCO6 protocol if possible.
- Measure 3: Facilitate Simultaneous
Operations (simops) in Ports. The simultaneous
operations of cargo loading and offloading, bunkering, cleaning of
tanks, and replenishing ship stores and other provisions would
minimize the time spent in port and reduce the corresponding GHG
- Measure 4: Optimize Port Stay
by Pre-Clearance. This Measure is intended to
eliminate waiting time for clearance into a port. Ideally,
pre-clearance could be arranged for port customs, port health
requirements, and immigration authorities as well as cargo, crew,
and passenger clearance in accord with the FAL
- Measure 5: Improve Planning of
Ships Calling at Multiple Berths in One Port. This
Measure recommends strategic organization to minimize the times
that a ship is in port.
- Measure 6:
Improve Ship/Berth Compatibility Through Improved Port
Master Data. Measure 6 recommends obtaining data
about the size restrictions of ports and berths by AIS (Automated
Information System) prior to seeking clearance. The AIS is
mandatory under SOLAS8 and certainly could provide ships
with valuable information about ports.
- Measure 7:
Enable Ship Deadweight Optimization Through Improved Port
Master Data. The Guide recommends improving
Port Master Data for tides, water depth and water density to
improve deadweight capability. The Measure recommends
that information concerning the deep water route, fairway, berth
pocket and harbor basin should be obtained prior to entry to the
- Measure 8: Optimize Speed
Between Ports. The Guide recommends arriving
promptly when berthing facilities are available to minimize time
spent waiting at a port.
The U.S. has implemented the AIS requirement from SOLAS in 46 U.S.C
