“Designing the New National Security Multi-Mission Vessel” for State Maritime Academies

MarineLink reports MARAD is planning a new class of ships to serve as training ships for the five State Maritime Academies (SMA). Additionally these ships are expected to be available to respond to Natural Disasters. The new design is being referred to as the National Security Multi-Mission Vessel (NSMV).

NSMMV Humanitarian Assistance Disaster Response facilities will be concentrated at the sternHerbert Engineering Corp (HEC) prepared a conceptual level design for the NSMV.

French Building OPVs

FrenchOPVBSAH

NavyRecognition reports the French have contracted for two OPVs with an option for two more.

In several respects, these ships are very different from most OPVs and particularly the Coast Guard’s Offshore Patrol Cutters (OPC) and Webber class WPCs.

France has a huge Exclusive Economic Zone, very nearly as large as that of the US, which is the largest in the world. These ships are intended to support France’s many island territories far from European France. Disaster Relief and Humanitarian Assistance is expected to be an important mission for these ships.

Structurally they appear much closer to a typical Offshore Industry Support Vessel. At 70.3 meters (231 feet) long, it is sized between the OPC and the WPC. Speed is relatively low at 14 knots. The crew is smaller than that of the Webber class, while the endurance is similar to that of the much larger OPCs.

Significantly, they have no helicopter facilities.
