Introduction 

1 Regulation D-3.1 of the International Convention for the Control and Management 

of Ships’ Ballast Water and Sediments stipulates that ballast water management systems must be 

approved by the Administration taking into account guidelines developed by the Organization. 

2 The Government of the United Kingdom wishes to notify the Committee of its decision to 

type approve the Hyde GUARDIANTM ballast water management system. 

3 The United Kingdom’s competent authority, the Maritime and Coastguard Agency, 

has verified the application dossier submitted by Hyde Marine Inc. for 

the Hyde GUARDIANTM and considers the system to satisfy the requirements of 

the Guidelines for approval of ballast water management systems (G8) adopted by 
MEPC 59/INF.20 - 2 -

resolution MEPC.174(58). Specifically, the United Kingdom considers that the application 

dossier, including the Environmental Acceptability Evaluation, has demonstrated that the 

system does not make use of an Active Substance. 

4 Testing of the Hyde GUARDIANTM ballast water management system was undertaken 

in 2008. Land-based tests were undertaken by the Royal Netherlands Institute for Sea Research 

(NIOZ) between April and July 2008, and shipboard trials conducted on board 

the Princess Cruise Lines ship M.V. Coral Princess with testing and analysis undertaken by 

the University of Maryland (United States), between April and October 2008. Both land and 

shipboard test methodologies and results are available to be downloaded from the Maritime and 

Coastguard Agency’s website (see paragraph 6.4). 

5 The United Kingdom has delegated the type approval of ballast water management 

systems under Guidelines (G8) to its recognized organizations. The Type Approval Certificate 

for the Hyde GUARDIANTM system has been issued on behalf of the United Kingdom 

Administration by the Lloyd’s Register. 

6 In accordance with resolution MEPC.175(58) “Information reporting on type approved 

ballast water management systems”, the following information is provided: 

 .1 Approval date: 29 April 2009;
