The project Milestones are defined as:
Milestone 1: Completion of the Pier 66 and Pier 91 east berth shore power extension
systems by the start of 2027 cruise season, including bollards and limited deck panel
replacements (Previously approved, in construction).
Milestone 2: completion of the Pier 91 west berth shore power extension and
rehabilitation of section of P91 delineated as DU #9202 by the start of 2028 cruise season
(today’s request: Post-Validation - design and GMP development funding; construction
will be a future request once GMP has been negotiated).
BACKGROUND
In July 2024, the Port passed Commission Order No. 2024-08 mandating all homeport cruise ships
to connect to shore power by 2027, three years earlier than the 2030 goal set in the Port’s
adopted Maritime Climate and Air Action Plan. The provision of shore power for cruise ships is
the Port’s greatest opportunity to improve local air quality and reduce Maritime greenhouse gas
(GHG) emissions from ocean going vessels at berth.
Currently, the Port’s Smith Cove Cruise Terminal at Terminal 91 at Pier 91 (P91) which opened in
2009 provides shore power at its two cruise berths. The single berth at the Bell Street Pier Cruise
Terminal at Pier 66 (P66) which opened in 1999 has a new shore power system completed in
September 2024. While all three of the Port’s cruise berths are now electrified, upgrades to the
shore power systems are required to provide the additional flexibility needed to accommodate
all vessels and berthing configurations to meet Commission Order No. 2024-08.
The project utilizes the Progressive Design Build (PDB) alternative delivery method and selected
Skanska USA Building, Inc. (Skanska) as the design-builder. The project returned to Commission
in December 2025 for Post-Validation Amendment authorization, and in May 2026 for funding
authorization to execute an Early Work Amendment for early procurement of long lead materials.
In June 2026 shore power construction on the west berth of Pier 91 was reprioritized to address
accelerating deterioration of the concrete precast deck panels in the section of the pier
delineated as DU #9202 that falls within the project footprint. Further investigation into the
condition of the panels has shown delamination, spalls, exposed/corroded reinforcing steel bar,
and elevated concentration of chloride ions. Operational load restrictions have been
implemented on twelve of the most deteriorated panels with further condition assessments
required every six months. To accommodate expeditious repair of DU #9202 to eliminate
additional operational restrictions, the PDB contract scope was split into two (2) milestones to
advance the majority of the shore power extensions at P66 and T91 by 2027, and accelerate the
repair of DU #9202 by a year in conjunction with the T91 west berth shore power extension by
2028.

Meeting Date: November 17, 2026

JUSTIFICATION
The Port of Seattle is an industry and regional leader in economic development and sustainability.
The Port’s investment in cruise terminals at P66 and P91 results in a significant contribution to
the region’s economy, generating more than 5,500 jobs and nearly $1.2 billion in total local
business revenue each cruise season. The Port also recognizes its responsibility and the
importance of concerted efforts to balance economic growth with sustainability. The Seattle
Waterfront Clean Energy Strategic Plan and the adopted Maritime Climate and Air Action Plan
provide a Port investment strategy to protect the environment and improve community health.
As a global leader in sustainability, the Port is committed to addressing global climate change and
improving local air quality. In 2017 the Port’s Commission adopted GHG reduction targets in
alignment with the Paris Climate Agreement, then updated goals in October 2021 in recognition
of the climate crisis. In November 2021, the Port Commission adopted the Maritime Climate and
Air Action Plan which identifies strategies and actions the Port can take through 2030 to achieve
Port’s Century Agenda GHG target to reduce GHG emissions 50% by 2030 and to position the Port
to phase out seaport-related emissions entirely by 2050. The plan includes a specific commitment
to install shore power at all cruise berths and maximize connections by 2030. In May 2022, the
Port launched a collaborative effort to explore the feasibility of a maritime green corridor aimed
at accelerating the deployment of low and zero GHG emission cruise ships and operations
between Alaska, British Columbia, and Washington. Most recently, the Port passed Commission
Order No. 2024-08 mandating that all home ported cruise ships must connect to shore power by
2027, three (3) years earlier than the Maritime Climate and Air Action Plan 2030 goal.
Shore power can significantly reduce GHG and air pollution emissions with each connection. Staff
estimate shore power can avoid approximately 268 thousand metric tons of carbon (CO2e)
cumulatively through 2050. Assuming a 25-year infrastructure life and $44 million cost, that
represents a cost per ton of carbon reduced over the full lifespan to range from $164 to $406 per
metric ton CO2e. This range is based on the 2025 cruise schedule with the current ability to
connect cruise ships to shore power at P91 and P66 (86% of homeport calls). If 100% of homeport
ships plug-in consistent with the Commission Order No. 2024-08 in 2027, shore power use would
result in an additional 45 thousand metric tons of cumulative carbon emissions avoided over a
25-year infrastructure life.
In addition to the significant economic and sustainability benefits provided by expanding cruise
shore power, rehabilitation of the P91 DU #9202 is critical to maintaining operational continuity
for both cruise operations and commercial fishing operations on the pier. Pier 91 provides critical
infrastructure necessary to sustain these industries within the Puget Sound region. Operational
load restrictions have been implemented on the most deteriorated deck panels within the pier
making repair of this section of the pier more urgent to minimize the potential for further
operational impacts.

Diversity in Contracting
The project team in coordination with the Diversity in Contracting Department has included a 6%
WMBE aspirational goal in the Progressive Design Build major work contract for this work to
design and construct the pathway for the shore power system and other structural elements of
the project and to install the Watts designed and procured shore power equipment.
The additional Milestone 2 scope was discussed with Diversity in Contracting. After review, the
6% WMBE goal will be maintained for the overall project, inclusive of both Milestone 1 and
Milestone 2. While the additional scope represents a significant increase in the project value,
some of the major added work, particularly the concrete-related scope, provides limited
opportunities for additional WMBE utilization. However, there are other elements within the
added scope that provide continued WMBE opportunities and should support the contractor in
achieving the established 6% goal. Based on the review of the overall scope and available WMBE
opportunities, the 6% goal remains appropriate for the project.
Community Engagement
Staff will continue to brief Magnolia and Queen Anne community leaders at the regular Port’s
Neighbors Advisory Committee meetings including project details and construction schedule.
Similar outreach is scheduled for waterfront businesses and neighbors near Pier 66.
Details:
The T91/P66 Cruise Shore Power Extension project is on schedule to meet the Commission order
to plug-in all shore-power equipped homeported ships by 2027 at Pier 66 and on the East berth
of Pier 91 (Milestone #1). Milestone 1 is now under construction. The extension of the shore-
power system on the west berth of Pier 91 and the rehabilitation of DU #9202 (Milestone #2) will
be completed the following year to plug-in all remaining homeport ships by 2028.
The Validation phase for Milestone 2 has been completed, and the Basis of Design, Target GMP
Budget, and Target Schedule has been agreed upon with the Design-Builder. Following
authorization of today’s request for funding for the Post-Validation Amendment, Milestone 2 will
progress through design and GMP development.
Due to the proprietary nature of the electrical shore power equipment and the ancipated long
lead me, a sole source purchasing contract with Was Marine was executed to ensure that
design and procurement of the equipment is completed and ready for installaon by Q1 of 2027
for Milestone 1 and Q1 of 2028 for Milestone 2. This equipment is currently in producon, and
milestone 1 work will include surplusing or recycling the equipment it replaces.
Scope:
This funding request is for the Post-Validaon Amendment for Milestone 2 scope package to be
completed by cruise season 2028.

Milestone 2:
- Pier 91 West Cruise Berth Design and GMP Development for:
o Cruise Shore Power
West berth cruise shore power extension system.
o DU #9202 Rehabilitaon
Replacement of remaining 34 precast deck panels along the bull rail between
footmark 780’ and 1,200’ and reconstruct the bull rail.
New reinforced concrete overlay slab in place of the exisng ballast and asphalt
overlay to rehabilitate DU #9202.
Ulies within the slab overlay including water, storm, and 480V commercial fishing
shore power electrical system.
Remaining Project Risks:
- Milestone 1 schedule is aggressive and has very lile float to accommodate unforeseen
condions. Risk conngency has been allocated to migate, as well as shi differenal
allowance to allow for more days per week to work.
- Milestone 2 schedule is aggressive and has very lile float to accommodate unforeseen
condions. This will require tribal concurrence for barge work to complete in a single
season. West berth shore power will be priorized for in-use by cruise season 2028,
however potenal need for a third season to complete all structural work exists.
- DU #9202 structural soluon costs are preliminary. Costs could increase due to escalaon,
feasibility, and constructability. Cost esmates will be updated at contract phases, and
design milestones and migaon measures implemented as feasible and as needed.
Schedule
The schedule to meet Commission Order No. 2024-08 is aggressive. Project constraints including
other concurrent or overlapping critical projects at P91, design and permitting schedule, supply
chain uncertainty, and highly constrained construction work windows due to cruise and
commercial fishing operations create the risk of schedule slippage. Schedule assumptions
account for best case permitting scenarios, including avoidance of in-water work (work
completed in the dry) and successful tribal negotiations to maximize work window between
cruise seasons and the tribal fishery. Due to critical repairs required for DU #9202 of Pier 91 dock,
the dock repairs have been added to the shore power scope, and the scope has been divided to
be completed over two seasons. A Progressive Design Build project delivery with a sole source
contract to Watts Marine for shore power equipment design and procurement was selected to
mitigate schedule risk to the extent possible. This Progressive Design Build contract with Skanska
allows for some acceleration of the design process and minimizes potential for unknown

ALTERNATIVES AND IMPLICATIONS CONSIDERED
Alternative 1 – Execute a post-validation amendment for Milestone 2 scope to be completed by
cruise season 2028 including west berth shore power and complete replacement of all deck
panels instead of structural slab.
Cost Implications: Additional $25M+ to replace all deck panels within DU #9202.
Pros:
(1) Deck panel construction methodology is well established, minimizing risks of delays due
to untested structural solutions.
Cons:
(1) Precludes consideration of all structural solutions for the rehabilitation of DU #9202 and
would likely require rework of the shore power during the dock repair.
(2) Moves the repair of DU #9202 to the original schedule for completion by 2029,
eliminating the opportunity to accelerate the project and avoid additional operational
constraint.
(3) Adds risk probability that additional operational restrictions will be applied to DU #9202
deck panels as they continue to deteriorate.
This is not the recommended alternative.
Alternative 2 – Execute a post-validation amendment for Milestone 2 scope to be completed by
cruise season 2028 including structural slab solution for DU #9202 Rehabilitation.
Cost Implications: Cost savings of $25M+ to integrate DU #9202 Rehabilitation into T91 shore
power project.
Pros:
(1) Meets the mandate of Commission Order No. 2024-08 for Milestone 1.
(2) Provides additional time for design advancement and cost certainty for Milestone 2,
primarily the development of a structural solution for DU #9202 of Pier 91.
(3) Accelerates the rehabilitation of DU #9202 by one year, minimizing risk of further
operational restrictions as the deck panels deteriorate.
(4) Avoids potential rework of the west berth cruise shore power by integrating the shore
power infrastructure with the dock rehabilitation solution.
(5) Less costly than full deck panel replacement.

ADDITIONAL BACKGROUND
Originally, P91 and P66 cruise shore power projects were envisioned as two separate projects
under two CIP #s. Initial funding for the P91 Cruise Shore Power Extension North was authorized
by Commission on August 8, 2023, inclusive of the purchase of two (2) mobile cable positioning
devices (CPD) under CIP # C801293. P66 Cruise Shore Power Extension was under CIP # C801983.
As part of a DORA executed on October 16, 2024, for a Progressive Design Build procurement
and early design for both projects, T91 Cruise Shore Power Extension, except for the costs
associated with the purchase of the CPDs which remained under C801293, was transferred to CIP
# C801983 with P66 to consolidate the projects under a single CIP and to help expedite both
projects to meet the mandate of Commission Order No. 2024-008 to connect all home ported
cruise ships to shore power by 2027.
