Cruise Ships

Hyde Marine was the first company to install ballast water treatment systems on cruise ships, and it continues to build compact, customizable, and modular systems to meet the specific needs of retrofit and new builds for cruise ships and passenger ships of every class. Hyde Marine has experience with multiple cruise ship retrofit projects and has completed installation and commissioning during service with no impact to schedule and no down-time for the vessel. With the demands of multiple port states, extra scrutiny, and the short turnaround time required for cruise ship yard periods, the Hyde GUARDIAN Gold® BWTS can provide the least impact to vessel operations.

Our typical solution uses a component system with filters and UV reactors located in the vessel's engine room near the ballast pumps. Power panels are installed in the ship's engine room or machinery spaces, and a control panel is installed in the cargo control room with additional remote panels either installed in the engine room or directly tied into the ship's automation system to allow operation of the system from numerous locations convenient to the crew. Our fully integrated solution is designed to meet all Class, IMO, and Port State requirements, and our solutions have been through numerous safety assessments to meet the most current requirements.


Hyde GUARDIAN Gold systems are scalable to meet the demands of even the highest flow systems.

  • Low Flow Ballast Systems - 150 to 250 m3/hr (HG250G)
  • Medium Flow Ballast System - 300 to 600 m3/hr (HG600G)
  • High Flow Ballast System - 700 to 1500 m3/hr (HG1488G)

In the Market

Hyde Marine supplied the first fully operational shipboard ballast water treatment system, which was installed and has been on the 'Regal Princess' since May 2000.

In 2003 after the IMO Ballast Water Treatment Convention requirements were better defined, Hyde Marine installed the Hyde Guardian® system aboard the Coral Princess. This system was tested extensively on land-based installations and on board the Coral Princess in the fall of 2004. The on-board tests demonstrated Hyde Marine's ability to meet the IMO BWT Convention requirements. Since that time, Hyde Marine has continued retrofitting BWTS on all remaining Princess Cruise Vessels.
