As a core, the valid applicable safety certificates required by the SOLAS convention and the applicable environmental compliance certificates required by MARPOL remain acceptable for general PSC compliance.
Alternatively, some flag states and class societies are issuing Mobile Offshore Unit (MOU) safety certificates based on the vessel meeting the design and operating criteria of the MODU Code, in lieu of (or in conjunction with) the applicable SOLAS safety certificates. There are a couple of important items to note in these cases:
1) Due to the unique designs and operations of many foreign wind farm vessels, the MODU code offers a logical and acceptable alternative level of safety, and so has been accepted for PSC compliance.
2) Some vessels are issued MOU certificates based on the national standards of the vessel’s flag state. National MOU certificates are not acceptable for PSC compliance. The vessel must have valid safety certificates associated with international convention or code (SOLAS or MODU Code).
Additionally, foreign vessels arriving with more than 12 persons in addition to crew (such as wind farm installation techs and the like) should be currently certificated to comply with international convention by certification as either a passenger ship or alternatively a Special Purpose vessel under the Special Purpose Ships (SPS) Code. For awareness purposes, the Industrial Persons (IP) Code has been accepted by IMO and is set to go into effect in July of 2024 as a new Chapter of SOLAS and will offer an alternative for large industrial vessels on international voyages carrying more than 12 industrial persons (per IMO definition). Note that this does not impact vessels approved under the MODU Code (since it already provides for the carriage of more than 12 persons in addition to crew on international voyages), as long as the vessel meets the lifesaving equipment carriage and operational requirements, versus simply the vessel design standards.
