Using a remotely controlled dredge, Brennan removed wastewater sludge from impoundments on the refinery site and dewatered the material with six 2-meter belt filter presses. The remotely controlled dredge added a layer of safety to the project, preventing any health risks that a Leverman might face if exposed to hydrogen sulfide gas released during the dredging process.

The purpose? For cruise ships to switch off their engines while docking and use electricity instead, conserving fuel and reducing emissions. This change would lead to cleaner air for Seattle and other ports adopting the same practice. ## **Procuring a Power Source**** for Pier 66 ** Pier 66 lacked a power source at that time, so the Port of Seattle began procuring one. The solution involved laying submarine cable on the seabed alongside Seattle's shore, linking Pier 66 to renewable energy from Seattle City Light. Here's how we did it.   [Read More](https://www.jfbrennan.com/blog/submarine-cable-shore-power) [**{count-facebook}](https://www.jfbrennan.com/blog/topic/remotely-operated-vehicle-rovs#)[**{count-twitter}](https://www.jfbrennan.com/blog/topic/remotely-operated-vehicle-rovs#)[**{count-linkedin}](https://www.jfbrennan.com/blog/topic/remotely-operated-vehicle-rovs#)[**](https://www.jfbrennan.com/blog/topic/remotely-operated-vehicle-rovs#) [All posts](https://www.jfbrennan.com/blog/all) ### Subscribe Here! ### Latest Blog Posts ### Posts by Topic - [Marine Construction (70)](https://www.jfbrennan.com/blog/topic/marine-construction) - [Corporate Culture (53)](https://www.jfbrennan.com/blog/topic/corporate-culture) - [Employee Engagement (50)](https://www.jfbrennan.com/blog/topic/employee-engagement) - [Great Place to Work (44)](https://www.jfbrennan.com/blog/topic/great-place-to-work) - [Environmental Dredging (41)](https://www.jfbrennan.com/blog/topic/environmental-dredging) - [J.F.
