SUBJECT:  Terminal 91 Cruise Shore Power Mobile Cable Positioning Devices Procurement 
(C801293) 
Amount of this request:               $2,500,000 
Total estimated project cost:          $2,750,000 

ACTION REQUESTED 
Request Commission authorization for the Executive Director to enter a contract for the
procurement of a proprietary shore power system consisting of two (2) mobile cable positioning
devices for Pier 91. This authorization is for $2,500,000 of a total estimated project cost of
$2,750,000. (CIP# C801293). 
EXECUTIVE SUMMARY 
The provision of shore power for cruise ships is the port’s greatest opportunity to reduce 
greenhouse gas (GHG) emissions and improve local air quality. To capitalize on the opportunity,
the Port is committed to collaborating with cruise lines to increase the number of annual shore
power-equipped homeport calls to 100 percent with a 100 percent connection rate by 2030.
Reaching these goals will require innovation and enhanced technology.  Currently, the Port’s
Smith Cove Cruise Terminal at Pier 91 provides shore power at its two cruise berths. However,
the ability to connect to shore power is constrained due to the fixed-location technology. 
The Terminal 91 Shore Power Extension project will add flexibility to the existing shore power
connection points on the east and west berths and will increase the connection rate of shore
power capable cruise ships by modifying the technology used today. Given the unique needs of 
each cruise vessel, leveraging the CPD innovation will enable more vessels to plug in. This 
approach ensures the highest optimization of the Port’s assets and lifespan.  
The first phase of the project requires the purchase of two (2) mobile cable positioning devices
(CPD) and minimal modification to the current shore power system. This approach uses the 
existing cabling and switch gear from the fixed jib crane and plugs them into the new CPD. The

current jib cranes have minimal reach because of their fixed location and can only accommodate
cruise ships with certain shore power plug configurations. Replacing the jib cranes on the east
and west berths of Pier 91 with mobile CPDs will allow a higher opportunity for cruise ships to
use shore power while at berth and will also result in operational flexibility in how ships use the
berths. 
A competition waiver has been executed to purchase the CPDs from Watts Marine, a local
company leading in shore power technology around the globe. Watts Marine currently operates
the shore power system and jib cranes at Pier 91 and will perform much of the work to transition
to the mobile CPDs.
A second phase of the shore power extension project will be completed later to extend a new
shore power cable and plug-in to the north end of the west berth. Planning for that phase of the
project is anticipated to start in Q4 2023. 
JUSTIFICATION 
This project supports the following Century Agenda and Maritime Division strategic goals: 
Century Agenda: 
1.  Responsibly Invest in the Economic Growth of the Region and All Its Communities 
2.  Be the Greenest and Most Energy Efficient Port in North America 
3.  Be a Highly Effective Public Agency 
Maritime Division: 
1.  Asset Management 
2.  Sustainability 
In addition, the project specifically addresses several near-term Ocean-Going Vessel (OGV)
strategic actions of the Port of Seattle’s Maritime Climate and Air Action Plan (MCAAP, 2021)
contributing to the overall 2030 goal of reducing annual emissions by approximately 13,000
Metric Tonnes CO2 and 8 Metric Tonnes diesel particulate matter (DPM) by maximizing the
potential for shore power connections: 
•    By 2025: Require shore power use by shore power‐equipped homeport cruise ships at
Terminal 91 for all shore power equipped ships. 
•    By 2030: Collaborate with cruise lines to increase the number of annual shore power
equipped calls at the Port with a goal to reach 100 percent shore power‐equipped
homeport calls and a 100 percent connection rate by 2030. 
This investment also contributes to the Port’s long-term commitment to reduce greenhouse gas
emissions as follows:

Meeting Date: August 8, 2023 
•    50 percent reduction by 2030 
•    Net zero or better by 2040 for port-controlled or indirect emissions 
•    Carbon neutral or better by 2050 for port-influences emissions 
Furthermore, the Port’s continued investment in shore power connectivity underscores the
organization’s commitment to near-port communities and the priority to decrease the impact of
operations on adjacent neighborhoods. A transition to the mobile CDPs will have an immediate
benefit to the Magnolia, Interbay and Queen Anne neighbors by increasing the potential for more
ships to use shore power while at the facility. 
In 2022, 69 of 83 equipped homeport calls connected to shore-power, an 83% rate, avoiding
2,000 tonnes greenhouse gas emissions. However, if all shore power-equipped homeport calls at
Pier 91 plugged in, 5,300 tonnes greenhouse gas emissions would be avoided (estimated based
on 2023 season). 
To meet the goal of 100 percent of shore-power capable vessels connecting to shore power, 
cruise facilities need to accommodate a wide-range of vessel types and connection configurations 
to minimize the times ships cannot plug in, including for weather and safety issues, technical
equipment challenges either on board or at the berth and alignment issues. For example, in 2023
two shore-power equipped ships at Pier 91 had alignment issues that required moving gangways 
weekly to establish a shore power connection. Combined, these cruise ships account for 39 calls
or 20% of total calls at Pier 91 and have a GHG reduction potential of 1,000 tonnes GHG. 
By replacing two (2) fixed jib cranes with mobile CPDs, this project enhances the flexibility of
cruise operations by providing more berthing options that allow cruise ships of various types,
sizes, and plug-in configurations to connect to shore-power, further eliminating fossil fuel
dependency while at the Port. Increasing operational flexibility of the shore power at Pier 91
moves the Port closer to achieving its sustainability goals.

Meeting Date: August 8, 2023 
Alternative 2 – Defer procurement of the mobile CPDs to a later date as part of the overall T91
Shore Power Extension project to include shore power cable and plug-in on the north end of the
west berth of Pier 91. 
Cost Implications: At 6% escalation per year, procuring the CPDs later could cost between
$100,000 to $250,000 assuming a 2-year delay. 
Pros: 
(1)   Retains Port capital for other priority projects and financial initiatives. 
(2)   Avoids a second season of temporary construction impacts to existing cruise operations
and commercial shipping business operations. 
(3)   Realizes efficiencies in consolidating construction into a single project, rather than
phasing over two or three years. 
Cons: 
(1)   Missed opportunity to implement long term goals and strategic objectives for Cruise
operations to become sustainable and to increase business opportunities. 
(2)   Continues to contribute to greenhouse gas emissions. 
(3)   Potential lost revenue from increased flexibility to allow more ships to call to port and
plug-in earlier. 
(4)    Adds complication to an easily phased project. 
This is not the recommended alternative. 
Alternative 3 – Procure two (2) mobile CPDs as the first phase of the Termina 91 Shore Power
Extension project. 
Cost Implications: No additional escalation will be applied to the overall cost. Savings of
potentially $250,000, more if the project is deferred longer than two years. 
Pros: 
(1)   Contributes to implementation of long-term goals and strategic objectives for Cruise
operations to become sustainable and to increase business opportunities. 
(2)   Reduces cruise contributions to greenhouse gas emissions. 
(3)   Increased revenue from additional flexibility to allow more ships to call to port and plugin.
(4)   Minimizes potential future supply chain issues should another globally impactful event
occurs (Covid, war, inflation). 
Cons: 
(1)   Requires large Port investment of funds. 
(2)   Creates temporary construction impacts to existing commercial shipping and tenant
business operations. 
This is the recommended alternative.
