According to this Defenceweb article the two preferred bidders for Biro and Hotel are Damen and SAS respectively. http://www.defenceweb.co.za/index.php?o ... Itemid=242 In my humble opinion this seems like a good way to go. Although I did think that Damen may have only been awarded the IPV part of Biro. I’m assuming the bare and basic hull of the OPV will be built in Europe (probably Romania like the Sarah Baartman) and then everything else done in Cape Town. I don’t think the yard in CT is big enough to build the proposed OPV design from scratch. The IPV will surely have some commonality with the Damen Stan 4708 patrol vessels that the DAFF have. This would be cost-effective and make sense. In terms of Hotel, and again in my humble opinion, I can imagine the hull and superstructure being built by SAS but a lot of the associated hydrographic equipment being supplied by overseas companies. Let’s see how this all unfolds. |

Damen's OPV offering is a Sea Axe design about 100m long, a decent size to handle the rough stuff and the long trips to the Prince Edward Islands and up both coasts on visits to our SADC neighbours. It's the largest of the OPV designs that were in the bidding. The Stan 4708 comes in a Coast Guard version that the USCG bought as the "Sentinel-class cutter" so there's already plenty experience of the type/role.

I thought one of the Biro requirements was to have a Helipad? |

Ah, my bad. Looks good then, a far cry from the Strike Craft. |

At around 60m they are too close to the natural "wavelength" of the usual South Atlantic storm swellls. A longer boat sits in two (or more) waves at the same time so they don't get tossed around so much. |

That picture of the USCG cutter looks like a IPV. It's rather small at 353 tons. Smaller than the strike craft. |

Yes that is the basic form of the IPV, but more to the point it is the exact same basic hull as the DAFF inshore boats, the three smaller ones, not the Sarah Baartman. There is however a very significant difference between the USCG boats and the IPV we are getting. The USCG version has substantially larger engines, for more speed but less endurance - they call it the "Fast Response Cutter, it is used as a "sprinter", not a patrol craft. They have dozens, based in harbours all around their coast, they don't spend weeks at sea, they wait to be called out to an incident, actually much like the way strike craft normally operate. Damen won the bid for BOTH the OPV and the IPV. |

The IPV design the navy will be receiving is based on the FCS 5009 design. It's a bit bigger than the DAFF vessels. http://products.damen.com/en/ranges/sta ... atrol-5009 |

Thanks Doug  So it will also be a "Sea Axe" design - which is a really good move given the otherwise poor seakeeping of ships of that length range in our Southeaster storm conditions. |

Damen Shipyards Cape Town have already built at least two FCS 5009 boats, so the local know-how already exists. http://www.damen.com/en/news/2015/01/fi ... _completed Damen.com's page about the FCS 5009 - http://products.damen.com/en/ranges/sta ... atrol-5009 Damen's own website does not yet have any specifics about the 2600 Sea Axe, but I found this article - http://www.naval-technology.com/project ... ol-vessel/ accompanied by this "photo album" - http://www.naval-technology.com/project ... ssel2.html |

The OPV will be based on the 1800 Sea Axe, not the 2600. |
