On Wednesday, March 11th, the RESOLVE Pioneer arrived at Lake Union, Seattle, where it would be dry-docked until April 11th. Over the course of a month, the tug underwent various inspections, including engine coolers and steering linkage. While there was very little wear to general components, upgrades were made to the propeller-shaft seal systems, with a new biodegradable lubricant added to the system for environment friendliness, keel-coolers and Kort Nozzles, among other things, and anodes were replaced. Twenty one center and twenty two portside ballast tanks underwent fairly extensive steel replacement, the fluorescent lights were changed, the tug was given a paint job and left for Anchorage looking brand new.
